Class CreateLaunchConfigurationRequest

    • Method Detail

      • launchConfigurationName

        public final String launchConfigurationName()

        The name of the launch configuration. This name must be unique per Region per account.

        Returns:
        The name of the launch configuration. This name must be unique per Region per account.

      • imageId

        public final String imageId()

        The ID of the Amazon Machine Image (AMI) that was assigned during registration. For more information, see Finding a Linux AMI in the Amazon EC2 User Guide for Linux Instances.

        If you specify InstanceId, an ImageId is not required.

        Returns:
        The ID of the Amazon Machine Image (AMI) that was assigned during registration. For more information, see Finding a Linux AMI in the Amazon EC2 User Guide for Linux Instances.

        If you specify InstanceId, an ImageId is not required.

      • hasSecurityGroups

        public final boolean hasSecurityGroups()
        For responses, this returns true if the service returned a value for the SecurityGroups property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • securityGroups

        public final List<String> securityGroups()

        A list that contains the security group IDs to assign to the instances in the Auto Scaling group. For more information, see Control traffic to resources using security groups in the Amazon Virtual Private Cloud User Guide.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSecurityGroups() method.

        Returns:
        A list that contains the security group IDs to assign to the instances in the Auto Scaling group. For more information, see Control traffic to resources using security groups in the Amazon Virtual Private Cloud User Guide.

      • hasClassicLinkVPCSecurityGroups

        public final boolean hasClassicLinkVPCSecurityGroups()
        For responses, this returns true if the service returned a value for the ClassicLinkVPCSecurityGroups property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasClassicLinkVPCSecurityGroups() method.

        Returns:
        Available for backward compatibility.

      • instanceId

        public final String instanceId()

        The ID of the instance to use to create the launch configuration. The new launch configuration derives attributes from the instance, except for the block device mapping.

      • ebsOptimized

        public final Boolean ebsOptimized()

        Specifies whether the launch configuration is optimized for EBS I/O (true) or not ( false). The optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization is not available with all instance types. Additional fees are incurred when you enable EBS optimization for an instance type that is not EBS-optimized by default. For more information, see Amazon EBS-optimized instances in the Amazon EC2 User Guide for Linux Instances.

        The default value is false.

      • associatePublicIpAddress

        public final Boolean associatePublicIpAddress()

        Specifies whether to assign a public IPv4 address to the group's instances.

      • placementTenancy

        public final String placementTenancy()

        The tenancy of the instance, either default or dedicated. An instance with dedicated tenancy runs on isolated, single-tenant hardware and can only be launched into a VPC. To launch dedicated instances into a shared tenancy VPC (a VPC with the instance placement tenancy attribute set to default), you must set the value of this property to dedicated. For more information, see Configuring instance tenancy with Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

        If you specify PlacementTenancy, you must specify at least one subnet for VPCZoneIdentifier when you create your group.

        Valid values: default | dedicated

        Returns:
        The tenancy of the instance, either default or dedicated. An instance with dedicated tenancy runs on isolated, single-tenant hardware and can only be launched into a VPC. To launch dedicated instances into a shared tenancy VPC (a VPC with the instance placement tenancy attribute set to default), you must set the value of this property to dedicated . For more information, see Configuring instance tenancy with Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.
