String name
The name of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, and periods are allowed.
String value
The value of the attribute. Up to 128 letters (uppercase and lowercase), numbers, hyphens, underscores, periods, at signs (@), forward slashes, colons, and spaces are allowed.
String targetType
The type of the target with which to attach the attribute. This parameter is required if you use the short form ID for a resource instead of the full Amazon Resource Name (ARN).
String targetId
The ID of the target. You can specify the short form ID for a resource or the full Amazon Resource Name (ARN).
String clusterArn
The Amazon Resource Name (ARN) that identifies the cluster. The ARN contains the arn:aws:ecs
namespace, followed by the region of the cluster, the AWS account ID of the cluster owner, the
cluster namespace, and then the cluster name. For example,
arn:aws:ecs:region:012345678910:cluster/test ..
String clusterName
A user-generated string that you use to identify your cluster.
String status
The status of the cluster. The valid values are ACTIVE or INACTIVE. ACTIVE
indicates that you can register container instances with the cluster and the associated instances can accept
tasks.
Integer registeredContainerInstancesCount
The number of container instances registered into the cluster.
Integer runningTasksCount
The number of tasks in the cluster that are in the RUNNING state.
Integer pendingTasksCount
The number of tasks in the cluster that are in the PENDING state.
Integer activeServicesCount
The number of services that are running on the cluster in an ACTIVE state. You can view these
services with ListServices.
String containerArn
The Amazon Resource Name (ARN) of the container.
String taskArn
The Amazon Resource Name (ARN) of the task.
String name
The name of the container.
String lastStatus
The last known status of the container.
Integer exitCode
The exit code returned from the container.
String reason
A short (255 max characters) human-readable string to provide additional details about a running or stopped container.
SdkInternalList<T> networkBindings
The network bindings associated with the container.
String name
The name of a container. If you are linking multiple containers together in a task definition, the
name of one container can be entered in the links of another container to connect the
containers. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This
parameter maps to name in the Create a
container section of the Docker Remote API and the
--name option to docker run.
String image
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker
Hub registry are available by default. Other repositories are specified with
repository-url/image:tag . Up to 255 letters (uppercase and lowercase),
numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter
maps to Image in the Create a
container section of the Docker Remote API and the
IMAGE parameter of docker run.
Images in Amazon ECR repositories use the full registry and repository URI (for example,
012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).
Images in official repositories on Docker Hub use a single name (for example, ubuntu or
mongo).
Images in other repositories on Docker Hub are qualified with an organization name (for example,
amazon/amazon-ecs-agent).
Images in other online repositories are qualified further by a domain name (for example,
quay.io/assemblyline/ubuntu).
Integer cpu
The number of cpu units reserved for the container. A container instance has 1,024 cpu
units for every CPU core. This parameter specifies the minimum amount of CPU to reserve for a container, and
containers share unallocated CPU units with other containers on the instance with the same ratio as their
allocated amount. This parameter maps to CpuShares in the Create a
container section of the Docker Remote API and the
--cpu-shares option to docker run.
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.
The Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to 2 CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
Integer memory
The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory
specified here, the container is killed. This parameter maps to Memory in the Create a
container section of the Docker Remote API and the
--memory option to docker run.
You must specify a non-zero integer for one or both of memory or memoryReservation in
container definitions. If you specify both, memory must be greater than
memoryReservation. If you specify memoryReservation, then that value is subtracted from
the available memory resources for the container instance on which the container is placed; otherwise, the value
of memory is used.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
Integer memoryReservation
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention,
Docker attempts to keep the container memory to this soft limit; however, your container can consume more memory
when it needs to, up to either the hard limit specified with the memory parameter (if applicable),
or all of the available memory on the container instance, whichever comes first. This parameter maps to
MemoryReservation in the Create a
container section of the Docker Remote API and the
--memory-reservation option to docker
run.
You must specify a non-zero integer for one or both of memory or memoryReservation in
container definitions. If you specify both, memory must be greater than
memoryReservation. If you specify memoryReservation, then that value is subtracted from
the available memory resources for the container instance on which the container is placed; otherwise, the value
of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for
short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard
limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the
remaining resources on the container instance, but also allow the container to consume more memory resources when
needed.
SdkInternalList<T> links
The link parameter allows containers to communicate with each other without the need for port
mappings, using the name parameter and optionally, an alias for the link. This
construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase),
numbers, hyphens, and underscores are allowed for each name and alias. For more
information on linking Docker containers, see https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/. This parameter maps to
Links in the Create a
container section of the Docker Remote API and the
--link option to docker run.
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
SdkInternalList<T> portMappings
The list of port mappings for the container. Port mappings allow containers to access ports on the host container
instance to send or receive traffic. This parameter maps to PortBindings in the Create a
container section of the Docker Remote API and the
--publish option to docker run. If the
network mode of a task definition is set to none, then you cannot specify port mappings. If the
network mode of a task definition is set to host, then host ports must either be undefined or they
must match the container port in the port mapping.
After a task reaches the RUNNING status, manual and automatic host and container port assignments
are visible in the Network Bindings section of a container description of a selected task in the Amazon
ECS console, or the networkBindings section DescribeTasks responses.
Boolean essential
If the essential parameter of a container is marked as true, and that container fails
or stops for any reason, all other containers that are part of the task are stopped. If the
essential parameter of a container is marked as false, then its failure does not affect
the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that is composed of multiple containers, you should group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon EC2 Container Service Developer Guide.
SdkInternalList<T> entryPoint
Early versions of the Amazon ECS container agent do not properly handle entryPoint parameters. If
you have problems using entryPoint, update your container agent or enter your commands and arguments
as command array items instead.
The entry point that is passed to the container. This parameter maps to Entrypoint in the Create a
container section of the Docker Remote API and the
--entrypoint option to docker run. For
more information, see https://docs.docker.com
/engine/reference/builder/#entrypoint.
SdkInternalList<T> command
The command that is passed to the container. This parameter maps to Cmd in the Create a
container section of the Docker Remote API and the
COMMAND parameter to docker run. For
more information, see https://docs.docker.com/engine
/reference/builder/#cmd.
SdkInternalList<T> environment
The environment variables to pass to a container. This parameter maps to Env in the Create a
container section of the Docker Remote API and the
--env option to docker run.
We do not recommend using plain text environment variables for sensitive information, such as credential data.
SdkInternalList<T> mountPoints
The mount points for data volumes in your container. This parameter maps to Volumes in the Create a
container section of the Docker Remote API and the
--volume option to docker run.

container section of the Docker Remote API and the
--volumes-from option to docker run.
String hostname
The hostname to use for your container. This parameter maps to Hostname in the Create a
container section of the Docker Remote API and the
--hostname option to docker run.
String user
The user name to use inside the container. This parameter maps to User in the Create a
container section of the Docker Remote API and the
--user option to docker run.
String workingDirectory
The working directory in which to run commands inside the container. This parameter maps to
WorkingDir in the Create a
container section of the Docker Remote API and the
--workdir option to docker run.
Boolean disableNetworking
When this parameter is true, networking is disabled within the container. This parameter maps to
NetworkDisabled in the Create a
container section of the Docker Remote API.
Boolean privileged
When this parameter is true, the container is given elevated privileges on the host container instance (similar
to the root user). This parameter maps to Privileged in the Create a
container section of the Docker Remote API and the
--privileged option to docker run.
Boolean readonlyRootFilesystem
When this parameter is true, the container is given read-only access to its root file system. This parameter maps
to ReadonlyRootfs in the Create a
container section of the Docker Remote API and the
--read-only option to docker run.
SdkInternalList<T> dnsServers
A list of DNS servers that are presented to the container. This parameter maps to Dns in the Create a
container section of the Docker Remote API and the
--dns option to docker run.
SdkInternalList<T> dnsSearchDomains
A list of DNS search domains that are presented to the container. This parameter maps to DnsSearch
in the Create
a container section of the Docker Remote API and the
--dns-search option to docker run.
SdkInternalList<T> extraHosts
A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This
parameter maps to ExtraHosts in the Create a
container section of the Docker Remote API and the
--add-host option to docker run.
SdkInternalList<T> dockerSecurityOptions
A list of strings to provide custom labels for SELinux and AppArmor multi-level security systems. This parameter
maps to SecurityOpt in the Create a
container section of the Docker Remote API and the
--security-opt option to docker run.
The Amazon ECS container agent running on a container instance must register with the
ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before
containers placed on that instance can use these security options. For more information, see Amazon ECS Container
Agent Configuration in the Amazon EC2 Container Service Developer Guide.
Map<K,V> dockerLabels
A key/value map of labels to add to the container. This parameter maps to Labels in the Create a
container section of the Docker Remote API and the
--label option to docker run. This
parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the
Docker Remote API version on your container instance, log into your container instance and run the following
command: sudo docker version | grep "Server API version"
SdkInternalList<T> ulimits
A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a
container section of the Docker Remote API and the
--ulimit option to docker run. Valid
naming values are displayed in the Ulimit data type. This parameter requires version 1.18 of the Docker
Remote API or greater on your container instance. To check the Docker Remote API version on your container
instance, log into your container instance and run the following command:
sudo docker version | grep "Server API version"
LogConfiguration logConfiguration
The log configuration specification for the container. This parameter maps to LogConfig in the Create a
container section of the Docker Remote API and the
--log-driver option to docker run. By
default, containers use the same logging driver that the Docker daemon uses; however the container may use a
different logging driver than the Docker daemon by specifying a log driver with this parameter in the container
definition. To use a different logging driver for a container, the log system must be configured properly on the
container instance (or on a different log server for remote logging options). For more information on the options
for different supported log drivers, see Configure logging drivers in the Docker
documentation.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the
Docker Remote API version on your container instance, log into your container instance and run the following
command: sudo docker version | grep "Server API version"
The Amazon ECS container agent running on a container instance must register the logging drivers available on
that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed
on that instance can use these log configuration options. For more information, see Amazon ECS Container
Agent Configuration in the Amazon EC2 Container Service Developer Guide.
String containerInstanceArn
The Amazon Resource Name (ARN) of the container instance. The ARN contains the arn:aws:ecs
namespace, followed by the region of the container instance, the AWS account ID of the container instance owner,
the container-instance namespace, and then the container instance ID. For example,
arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID .
String ec2InstanceId
The EC2 instance ID of the container instance.
Long version
The version counter for the container instance. Every time a container instance experiences a change that
triggers a CloudWatch event, the version counter is incremented. If you are replicating your Amazon ECS container
instance state with CloudWatch events, you can compare the version of a container instance reported by the Amazon
ECS APIs with the version reported in CloudWatch events for the container instance (inside the
detail object) to verify that the version in your event stream is current.
VersionInfo versionInfo
The version information for the Amazon ECS container agent and Docker daemon running on the container instance.
SdkInternalList<T> remainingResources
For most resource types, this parameter describes the remaining resources of the container instance that are available for new tasks. For port resource types, this parameter describes the ports that are reserved by the Amazon ECS container agent and any containers that have reserved port mappings; any port that is not specified here is available for new tasks.
SdkInternalList<T> registeredResources
For most resource types, this parameter describes the registered resources on the container instance that are in use by current tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent when it registered the container instance with Amazon ECS.
String status
The status of the container instance. The valid values are ACTIVE, INACTIVE, or
DRAINING. ACTIVE indicates that the container instance can accept tasks.
DRAINING indicates that new tasks are not placed on the container instance and any service tasks
running on the container instance are removed if possible. For more information, see Container
Instance Draining in the Amazon EC2 Container Service Developer Guide.
Boolean agentConnected
This parameter returns true if the agent is actually connected to Amazon ECS. Registered instances
with an agent that may be unhealthy or stopped return false, and instances without a connected agent
cannot accept placement requests.

(ARN) of the task definition to run in your service. If a revision is not specified, the latest
ACTIVE revision is used.
SdkInternalList<T> loadBalancers
A load balancer object representing the load balancer to use with your service. Currently, you are limited to one load balancer or target group per service. After you create a service, the load balancer name or target group ARN, container name, and container port specified in the service definition are immutable.
For Elastic Load Balancing Classic load balancers, this object must contain the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer. When a task from this service is placed on a container instance, the container instance is registered with the load balancer specified here.
For Elastic Load Balancing Application load balancers, this object must contain the load balancer target group ARN, the container name (as it appears in a container definition), and the container port to access from the load balancer. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group specified here.
Integer desiredCount
The number of instantiations of the specified task definition to place and keep running on your cluster.
String clientToken
Unique, case-sensitive identifier you provide to ensure the idempotency of the request. Up to 32 ASCII characters are allowed.
String role
The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load
balancer on your behalf. This parameter is required if you are using a load balancer with your service. If you
specify the role parameter, you must also specify a load balancer object with the
loadBalancers parameter.
If your specified role has a path other than /, then you must either specify the full role ARN (this
is recommended) or prefix the role name with the path. For example, if a role with the name bar has
a path of /foo/ then you would specify /foo/bar as the role name. For more information,
see Friendly Names and Paths in the IAM User Guide.
DeploymentConfiguration deploymentConfiguration
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

Date updatedAt
The Unix timestamp for when the service was last updated.
Integer maximumPercent
The upper limit (as a percentage of the service's desiredCount) of the number of tasks that are
allowed in the RUNNING or PENDING state in a service during a deployment. The maximum
number of tasks during a deployment is the desiredCount multiplied by maximumPercent
/100, rounded down to the nearest integer value.
Integer minimumHealthyPercent
The lower limit (as a percentage of the service's desiredCount) of the number of running tasks that
must remain in the RUNNING state in a service during a deployment. The minimum healthy tasks during
a deployment is the desiredCount multiplied by minimumHealthyPercent/100, rounded up to
the nearest integer value.
String cluster
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to deregister. If you do not specify a cluster, the default cluster is assumed.
String containerInstance
The container instance ID or full Amazon Resource Name (ARN) of the container instance to deregister. The ARN
contains the arn:aws:ecs namespace, followed by the region of the container instance, the AWS
account ID of the container instance owner, the container-instance namespace, and then the container
instance ID. For example,
arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID .
Boolean force
Forces the deregistration of the container instance. If you have tasks running on the container instance when you
deregister it with the force option, these tasks remain running until you terminate the instance or
the tasks stop through some other means, but they are orphaned (no longer monitored or accounted for by Amazon
ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler
starts another copy of that task, on a different container instance if possible.
Any containers in orphaned service tasks that are registered with a Classic load balancer or an Application load balancer target group are deregistered, and they will begin connection draining according to the settings on the load balancer or target group.
ContainerInstance containerInstance

String sourcePath
The path on the host container instance that is presented to the container. If this parameter is empty, then the
Docker daemon has assigned a host path for you. If the host parameter contains a
sourcePath file location, then the data volume persists at the specified location on the host
container instance until you delete it manually. If the sourcePath value does not exist on the host
container instance, the Docker daemon creates it. If the location does exist, the contents of the source path
folder are exported.
String cluster

maxResults was used and the results exceeded the value of that parameter. Pagination continues from
the end of the previous results that returned the nextToken value. This value is null
when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of cluster results returned by ListAttributes in paginated output. When this
parameter is used, ListAttributes only returns maxResults results in a single page
along with a nextToken response element. The remaining results of the initial request can be seen by
sending another ListAttributes request with the returned nextToken value. This value
can be between 1 and 100. If this parameter is not used, then ListAttributes returns up to 100
results and a nextToken value if applicable.
SdkInternalList<T> attributes
A list of attribute objects that meet the criteria of the request.
String nextToken

String nextToken
The nextToken value returned from a previous paginated ListClusters request where
maxResults was used and the results exceeded the value of that parameter. Pagination continues from
the end of the previous results that returned the nextToken value. This value is null
when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of cluster results returned by ListClusters in paginated output. When this
parameter is used, ListClusters only returns maxResults results in a single page along
with a nextToken response element. The remaining results of the initial request can be seen by
sending another ListClusters request with the returned nextToken value. This value can
be between 1 and 100. If this parameter is not used, then ListClusters returns up to 100 results and
a nextToken value if applicable.
SdkInternalList<T> clusterArns
The list of full Amazon Resource Name (ARN) entries for each cluster associated with your account.
String nextToken
The nextToken value to include in a future ListClusters request. When the results of a
ListClusters request exceed maxResults, this value can be used to retrieve the next
page of results. This value is null when there are no more results to return.
String cluster
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instances to list. If you do not specify a cluster, the default cluster is assumed.
String filter
You can filter the results of a ListContainerInstances operation with cluster query language
statements. For more information, see Cluster Query
Language in the Amazon EC2 Container Service Developer Guide.
String nextToken
The nextToken value returned from a previous paginated ListContainerInstances request
where maxResults was used and the results exceeded the value of that parameter. Pagination continues
from the end of the previous results that returned the nextToken value. This value is
null when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of container instance results returned by ListContainerInstances in paginated
output. When this parameter is used, ListContainerInstances only returns maxResults
results in a single page along with a nextToken response element. The remaining results of the
initial request can be seen by sending another ListContainerInstances request with the returned
nextToken value. This value can be between 1 and 100. If this parameter is not used, then
ListContainerInstances returns up to 100 results and a nextToken value if applicable.
String status
Filters the container instances by status. For example, if you specify the DRAINING status, the
results include only container instances that have been set to DRAINING using
UpdateContainerInstancesState. If you do not specify this parameter, the default is to include container
instances set to ACTIVE and DRAINING.
SdkInternalList<T> containerInstanceArns
The list of container instances with full Amazon Resource Name (ARN) entries for each container instance associated with the specified cluster.
String nextToken
The nextToken value to include in a future ListContainerInstances request. When the
results of a ListContainerInstances request exceed maxResults, this value can be used
to retrieve the next page of results. This value is null when there are no more results to return.
String cluster
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the services to list. If you do not specify a cluster, the default cluster is assumed.
String nextToken
The nextToken value returned from a previous paginated ListServices request where
maxResults was used and the results exceeded the value of that parameter. Pagination continues from
the end of the previous results that returned the nextToken value. This value is null
when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of container instance results returned by ListServices in paginated output. When
this parameter is used, ListServices only returns maxResults results in a single page
along with a nextToken response element. The remaining results of the initial request can be seen by
sending another ListServices request with the returned nextToken value. This value can
be between 1 and 10. If this parameter is not used, then ListServices returns up to 10 results and a
nextToken value if applicable.
SdkInternalList<T> serviceArns
The list of full Amazon Resource Name (ARN) entries for each service associated with the specified cluster.
String nextToken
The nextToken value to include in a future ListServices request. When the results of a
ListServices request exceed maxResults, this value can be used to retrieve the next
page of results. This value is null when there are no more results to return.
String familyPrefix
The familyPrefix is a string that is used to filter the results of
ListTaskDefinitionFamilies. If you specify a familyPrefix, only task definition family
names that begin with the familyPrefix string are returned.
String status
The task definition family status with which to filter the ListTaskDefinitionFamilies results. By
default, both ACTIVE and INACTIVE task definition families are listed. If this
parameter is set to ACTIVE, only task definition families that have an ACTIVE task
definition revision are returned. If this parameter is set to INACTIVE, only task definition
families that do not have any ACTIVE task definition revisions are returned. If you paginate the
resulting output, be sure to keep the status value constant in each subsequent request.
String nextToken
The nextToken value returned from a previous paginated ListTaskDefinitionFamilies
request where maxResults was used and the results exceeded the value of that parameter. Pagination
continues from the end of the previous results that returned the nextToken value. This value is
null when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of task definition family results returned by ListTaskDefinitionFamilies in
paginated output. When this parameter is used, ListTaskDefinitions only returns
maxResults results in a single page along with a nextToken response element. The
remaining results of the initial request can be seen by sending another ListTaskDefinitionFamilies
request with the returned nextToken value. This value can be between 1 and 100. If this parameter is
not used, then ListTaskDefinitionFamilies returns up to 100 results and a nextToken
value if applicable.
SdkInternalList<T> families
The list of task definition family names that match the ListTaskDefinitionFamilies request.
String nextToken
The nextToken value to include in a future ListTaskDefinitionFamilies request. When the
results of a ListTaskDefinitionFamilies request exceed maxResults, this value can be
used to retrieve the next page of results. This value is null when there are no more results to
return.
String familyPrefix
The full family name with which to filter the ListTaskDefinitions results. Specifying a
familyPrefix limits the listed task definitions to task definition revisions that belong to that
family.
String status
The task definition status with which to filter the ListTaskDefinitions results. By default, only
ACTIVE task definitions are listed. By setting this parameter to INACTIVE, you can view
task definitions that are INACTIVE as long as an active task or service still references them. If
you paginate the resulting output, be sure to keep the status value constant in each subsequent
request.
String sort
The order in which to sort the results. Valid values are ASC and DESC. By default (
ASC), task definitions are listed lexicographically by family name and in ascending numerical order
by revision so that the newest task definitions in a family are listed last. Setting this parameter to
DESC reverses the sort order on family name and revision so that the newest task definitions in a
family are listed first.
String nextToken
The nextToken value returned from a previous paginated ListTaskDefinitions request
where maxResults was used and the results exceeded the value of that parameter. Pagination continues
from the end of the previous results that returned the nextToken value. This value is
null when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of task definition results returned by ListTaskDefinitions in paginated output.
When this parameter is used, ListTaskDefinitions only returns maxResults results in a
single page along with a nextToken response element. The remaining results of the initial request
can be seen by sending another ListTaskDefinitions request with the returned nextToken
value. This value can be between 1 and 100. If this parameter is not used, then ListTaskDefinitions
returns up to 100 results and a nextToken value if applicable.
SdkInternalList<T> taskDefinitionArns
The list of task definition Amazon Resource Name (ARN) entries for the ListTaskDefinitions request.
String nextToken
The nextToken value to include in a future ListTaskDefinitions request. When the
results of a ListTaskDefinitions request exceed maxResults, this value can be used to
retrieve the next page of results. This value is null when there are no more results to return.
String cluster
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the tasks to list. If you do not specify a cluster, the default cluster is assumed.
String containerInstance
The container instance ID or full Amazon Resource Name (ARN) of the container instance with which to filter the
ListTasks results. Specifying a containerInstance limits the results to tasks that
belong to that container instance.
String family
The name of the family with which to filter the ListTasks results. Specifying a family
limits the results to tasks that belong to that family.
String nextToken
The nextToken value returned from a previous paginated ListTasks request where
maxResults was used and the results exceeded the value of that parameter. Pagination continues from
the end of the previous results that returned the nextToken value. This value is null
when there are no more results to return.
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
Integer maxResults
The maximum number of task results returned by ListTasks in paginated output. When this parameter is
used, ListTasks only returns maxResults results in a single page along with a
nextToken response element. The remaining results of the initial request can be seen by sending
another ListTasks request with the returned nextToken value. This value can be between
1 and 100. If this parameter is not used, then ListTasks returns up to 100 results and a
nextToken value if applicable.
String startedBy
The startedBy value with which to filter the task results. Specifying a startedBy value
limits the results to tasks that were started with that value.
String serviceName
The name of the service with which to filter the ListTasks results. Specifying a
serviceName limits the results to tasks that belong to that service.
String desiredStatus
The task desired status with which to filter the ListTasks results. Specifying a
desiredStatus of STOPPED limits the results to tasks that ECS has set the desired
status to STOPPED, which can be useful for debugging tasks that are not starting properly or have
died or finished. The default status filter is RUNNING, which shows tasks that ECS has set the
desired status to RUNNING.
Although you can filter results based on a desired status of PENDING, this will not return any
results because ECS never sets the desired status of a task to that value (only a task's lastStatus
may have a value of PENDING).
SdkInternalList<T> taskArns
The list of task Amazon Resource Name (ARN) entries for the ListTasks request.
String nextToken
The nextToken value to include in a future ListTasks request. When the results of a
ListTasks request exceed maxResults, this value can be used to retrieve the next page
of results. This value is null when there are no more results to return.
String targetGroupArn

String loadBalancerName
The name of a Classic load balancer.
String containerName

Integer containerPort
The port on the container to associate with the load balancer. This port must correspond to a
containerPort in the service's task definition. Your container instances must allow ingress traffic
on the hostPort of the port mapping.
String logDriver
The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.
If you have a custom driver that is not listed above that you would like to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that is available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, Amazon Web Services does not currently provide support for running modified copies of this software.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the
Docker Remote API version on your container instance, log into your container instance and run the following
command: sudo docker version | grep "Server API version"
Map<K,V> options
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote
API or greater on your container instance. To check the Docker Remote API version on your container instance, log
into your container instance and run the following command:
sudo docker version | grep "Server API version"
String sourceVolume
The name of the volume to mount.
String containerPath
The path on the container to mount the host volume at.
Boolean readOnly
If this value is true, the container has read-only access to the volume. If this value is
false, then the container can write to the volume. The default value is false.
String bindIP
The IP address that the container is bound to on the container instance.
Integer containerPort
The port number on the container that is be used with the network binding.
Integer hostPort
The port number on the host that is used with the network binding.
String protocol
The protocol used for the network binding.
String type
The type of constraint. Use distinctInstance to ensure that each task in a particular group is
running on a different container instance. Use memberOf to restrict selection to a group of valid
candidates. Note that distinctInstance is not supported in task definitions.
String expression
A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the
constraint type is distinctInstance. For more information, see Cluster Query
Language in the Amazon EC2 Container Service Developer Guide.
String type
The type of placement strategy. The random placement strategy randomly places tasks on available
candidates. The spread placement strategy spreads placement across available candidates evenly based
on the field parameter. The binpack strategy places tasks on available candidates that
have the least available amount of the resource that is specified with the field parameter. For
example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory
(but still enough to run the task).
String field
The field to apply the placement strategy against. For the spread placement strategy, valid values
are instanceId (or host, which has the same effect), or any platform or custom
attribute that is applied to a container instance, such as attribute:ecs.availability-zone. For the
binpack placement strategy, valid values are cpu and memory. For the
random placement strategy, this field is not used.
Integer containerPort
The port number on the container that is bound to the user-specified or automatically assigned host port. If you
specify a container port and not a host port, your container automatically receives a host port in the ephemeral
port range (for more information, see hostPort). Port mappings that are automatically assigned in
this way do not count toward the 100 reserved ports limit of a container instance.
Integer hostPort
The port number on the container instance to reserve for your container. You can specify a non-reserved host port
for your container port mapping, or you can omit the hostPort (or set it to 0) while
specifying a containerPort and your container automatically receives a port in the ephemeral port
range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under
/proc/sys/net/ipv4/ip_local_port_range; if this kernel parameter is unavailable, the default
ephemeral port range of 49153 to 65535 is used. You should not attempt to specify a host port in the ephemeral
port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the
ephemeral port range.
The default ephemeral port range of 49153 to 65535 will always be used for Docker versions prior to 1.6.0.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent
ports 51678 and 51679. Any host port that was previously specified in a running task is also reserved while the
task is running (after a task stops, the host port is released).The current reserved ports are displayed in the
remainingResources of DescribeContainerInstances output, and a container instance may have up
to 100 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count
toward the 100 reserved ports limit).
String protocol
The protocol used for the port mapping. Valid values are tcp and udp. The default is
tcp.
String cluster
The short name or full Amazon Resource Name (ARN) of the cluster that contains the resource to apply attributes. If you do not specify a cluster, the default cluster is assumed.

SdkInternalList<T> attributes
The attributes applied to your resource.
String cluster
The short name or full Amazon Resource Name (ARN) of the cluster with which to register your container instance. If you do not specify a cluster, the default cluster is assumed.
String instanceIdentityDocument
The instance identity document for the EC2 instance to register. This document can be found by running the
following command from the instance:
curl http://169.254.169.254/latest/dynamic/instance-identity/document/
String instanceIdentityDocumentSignature
The instance identity document signature for the EC2 instance to register. This signature can be found by running
the following command from the instance:

(uppercase and lowercase), numbers, hyphens, and underscores are allowed.
String taskRoleArn
The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon EC2 Container Service Developer Guide.
String networkMode
The Docker networking mode to use for the containers in the task. The valid values are none,
bridge, and host.
The default Docker network mode is bridge. If the network mode is set to none, you
cannot specify port mappings in your container definitions, and the task's containers do not have external
connectivity. The host network mode offers the highest networking performance for containers because
they use the host network stack instead of the virtualized network stack provided by the bridge
mode; however, exposed container ports are mapped directly to the corresponding host port, so you cannot take
advantage of dynamic host port mappings or run multiple instantiations of the same task on a single container
instance if port mappings are used.
For more information, see Network settings in the Docker run reference.

The short name or full Amazon Resource Name (ARN) of the cluster that your service is running on. If you do not specify a cluster, the default cluster is assumed.
String service
The name of the service to update.
Integer desiredCount
The number of instantiations of the task to place and keep running in your service.
String taskDefinition
The family and revision (family:revision) or full Amazon Resource Name
(ARN) of the task definition to run in your service. If a revision is not specified, the latest
ACTIVE revision is used. If you modify the task definition with UpdateService, Amazon
ECS spawns a task with the new version of the task definition and then stops an old task after the new version is
running.
DeploymentConfiguration deploymentConfiguration
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
Service service
The full description of your service following the update call.
String agentVersion
The version number of the Amazon ECS container agent.
String agentHash
The Git commit hash for the Amazon ECS container agent build on the amazon-ecs-agent GitHub repository.
String dockerVersion
The Docker version running on the container instance.
String name
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are
allowed. This name is referenced in the sourceVolume parameter of container definition
mountPoints.
HostVolumeProperties host
The contents of the host parameter determine whether your data volume persists on the host container
instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for
your data volume, but the data is not guaranteed to persist after the containers associated with it stop running.
String sourceContainer
The name of another container within the same task definition to mount volumes from.
Boolean readOnly
If this value is true, the container has read-only access to the volume. If this value is
false, then the container can write to the volume. The default value is false.
