public interface AWSSimpleSystemsManagement

Interface for accessing Amazon SSM.

Simple Systems Manager (SSM) enables you to remotely manage the configuration of your Amazon EC2 instance. Using SSM, you can run scripts or commands using either EC2 Run Command or SSM Config. (SSM Config is currently available only for Windows instances.)

Run Command

Run Command provides an on-demand experience for executing commands. You can use pre-defined Amazon SSM documents to perform the actions listed later in this section, or you can create your own documents. With these documents, you can remotely configure your instances by sending commands using the Commands page in the Amazon EC2 console, AWS Tools for Windows PowerShell, or the AWS CLI.

Run Command reports the status of the command execution for each instance targeted by a command. You can also audit the command execution to understand who executed commands, when, and what changes were made. By switching between different SSM documents, you can quickly configure your instances with different types of commands. To get started with Run Command, verify that your environment meets the prerequisites for remotely running commands on EC2 instances (Linux or Windows).

SSM Config

SSM Config is a lightweight instance configuration solution. SSM Config is currently only available for Windows instances. With SSM Config, you can specify a setup configuration for your instances. SSM Config is similar to EC2 User Data, which is another way of running one-time scripts or applying settings during instance launch. SSM Config is an extension of this capability. Using SSM documents, you can specify which actions the system should perform on your instances, including which applications to install, which AWS Directory Service directory to join, which Microsoft PowerShell modules to install, etc. If an instance is missing one or more of these configurations, the system makes those changes. By default, the system checks every five minutes to see if there is a new configuration to apply as defined in a new SSM document. If so, the system updates the instances accordingly. In this way, you can remotely maintain a consistent configuration baseline on your instances. SSM Config is available using the AWS CLI or the AWS Tools for Windows PowerShell. For more information, see Managing Windows Instance Configuration.

SSM Config and Run Command include the following pre-defined documents.

Name Description Platform

AWS-RunShellScript

Run shell scripts

Linux

AWS-UpdateSSMAgent

Update the Amazon SSM agent

Linux

AWS-JoinDirectoryServiceDomain

Join an AWS Directory

Windows

AWS-RunPowerShellScript

Run PowerShell commands or scripts

Windows

AWS-UpdateEC2Config

Update the EC2Config service

Windows

AWS-ConfigureWindowsUpdate

Configure Windows Update settings

Windows

AWS-InstallApplication

Install, repair, or uninstall software using an MSI package

Windows

AWS-InstallPowerShellModule

Install PowerShell modules

Windows

AWS-ConfigureCloudWatch

Configure Amazon CloudWatch Logs to monitor applications and systems

Windows

The commands or scripts specified in SSM documents run with administrative privilege on your instances because the Amazon SSM agent runs as root on Linux and the EC2Config service runs in the Local System account on Windows. If a user has permission to execute any of the pre-defined SSM documents (any document that begins with AWS-*) then that user also has administrator access to the instance. Delegate access to SSM and Run Command judiciously. This becomes extremely important if you create your own SSM documents. Amazon Web Services does not provide guidance about how to create secure SSM documents. You create SSM documents and delegate access to Run Command at your own risk. As a security best practice, we recommend that you assign access to "AWS-*" documents, especially the AWS-RunShellScript document on Linux and the AWS-RunPowerShellScript document on Windows, to trusted administrators only. You can create SSM documents for specific tasks and delegate access to non-administrators.

Method Detail

setEndpoint

void setEndpoint(String endpoint)

Overrides the default endpoint for this client ("https://ssm.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

Callers can pass in just the endpoint (ex: "ssm.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://ssm.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912

This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:

endpoint - The endpoint (ex: "ssm.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://ssm.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

setRegion

void setRegion(Region region)

An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.

This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:

region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.

See Also:

Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration), Region.isServiceSupported(String)

createAssociationBatch

CreateAssociationBatchResult createAssociationBatch(CreateAssociationBatchRequest createAssociationBatchRequest)

Associates the specified SSM document with the specified instances.

When you associate an SSM document with an instance, the configuration agent on the instance processes the document and configures the instance as specified.

If you associate a document with an instance that already has an associated document, the system throws the AssociationAlreadyExists exception.

shutdown

void shutdown()

Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:

request - The originally executed request.

Returns:

The response metadata for the specified request, or null if none is available.
