getExecutionRoleArn

public final String getExecutionRoleArn()

Description copied from interface: CfnTaskDefinitionProps

The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make AWS API calls on your behalf.

For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide .

getFamily

public final String getFamily()

Description copied from interface: CfnTaskDefinitionProps

The name of a family that this task definition is registered to.

Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.

To use revision numbers when you update a task definition, specify this property. If you don't specify a value, AWS CloudFormation generates a new task definition each time that you update it.

getIpcMode

public final String getIpcMode()

Description copied from interface: CfnTaskDefinitionProps

The IPC resource namespace to use for the containers in the task.

The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance.

If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose.

If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .

• For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.
• For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.

This parameter is not supported for Windows containers or tasks run on AWS Fargate .

getMemory

public final String getMemory()

Description copied from interface: CfnTaskDefinitionProps

The amount (in MiB) of memory used by the task.

If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition .

If your tasks runs on AWS Fargate , this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter.

• 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU)
• 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU)
• 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)
• Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU)
• Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU)
• Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192 (8 vCPU)

This option requires Linux platform 1.4.0 or later.

• Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU)

This option requires Linux platform 1.4.0 or later.

getNetworkMode

public final String getNetworkMode()

Description copied from interface: CfnTaskDefinitionProps

The Docker networking mode to use for the containers in the task.

The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .

For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.

If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .

If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.

getNetworkMode in interface CfnTaskDefinitionProps

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ecs-taskdefinition.html#cfn-ecs-taskdefinition-networkmode

getPidMode

public final String getPidMode()

Description copied from interface: CfnTaskDefinitionProps

The process namespace to use for the containers in the task.

The valid values are host or task . On Fargate for Linux containers, the only valid value is task . For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.

If task is specified, all containers within the specified task share the same process namespace.

If no value is specified, the default is a private namespace for each container.

If the host PID mode is used, there's a heightened risk of undesired process namespace exposure.

This parameter is not supported for Windows containers. > This parameter is only supported for tasks that are hosted on AWS Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

getProxyConfiguration

public final Object getProxyConfiguration()

Description copied from interface: CfnTaskDefinitionProps

The configuration details for the App Mesh proxy.

Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, they contain the required versions of the container agent and ecs-init .

public final List<CfnTag> getTags()

Description copied from interface: CfnTaskDefinitionProps

The metadata that you apply to the task definition to help you categorize and organize them.

Each tag consists of a key and an optional value. You define both of them.

The following basic restrictions apply to tags:

• Maximum number of tags per resource - 50
• For each resource, each tag key must be unique, and each tag key can have only one value.
• Maximum key length - 128 Unicode characters in UTF-8
• Maximum value length - 256 Unicode characters in UTF-8
• If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : /
