Tagging Resources

The Amazon ECS CLI supports adding metadata in the form of resource tags to your AWS resources. Each tag consists of a key and an optional value. Resource tags can be used for cost allocation, automation, and access control. For more information, see AWS Tagging Strategies.

When using the ecs-cli compose create command, using the --tags flag enables you to add metadata tags to the task definition.

Examples

Register a Task Definition

This example creates a task definition with the project name hello-world from the hello-world.yml Compose file.

ecs-cli compose --project-name hello-world --file hello-world.yml create --launch-type EC2

Output:

INFO[0000] Using ECS task definition                     TaskDefinition=ecscompose-hello-world:5

Register a Task Definition Using the EC2 Launch Type Without Task Networking

This example creates a task definition with the project name hello-world from the hello-world.yml Compose file. Additional ECS parameters specified for the container size parameters.

Example Docker Compose file, named hello-world.yml:

version: '3'
services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    logging:
      driver: awslogs
      options:
        awslogs-group: /ecs/cli/tutorial
        awslogs-region: us-east-1
        awslogs-stream-prefix: nginx

Example ECS parameters file, named ecs-params.yml:

version: 1
task_definition:
  services:
    nginx:
      cpu_shares: 256
      mem_limit: 0.5GB
      mem_reservation: 0.5GB

ecs-cli compose --project-name hello-world --file hello-world.yml --ecs-params ecs-params.yml --region us-east-1 create --launch-type EC2

Output:

INFO[0000] Using ECS task definition                     TaskDefinition=ecscompose-hello-world:5

Register a Task Definition Using the Fargate Launch Type

This example creates a task definition with the project name hello-world from the hello-world.yml Compose file. Additional ECS parameters are specified for task networking configuration for the Fargate launch type. Then one instance of the task is run.

Example Docker Compose file, named hello-world.yml:

version: '3'
services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    logging:
      driver: awslogs
      options: 
        awslogs-group: tutorial
        awslogs-region: us-east-1
        awslogs-stream-prefix: nginx

Example ECS parameters file, named ecs-params.yml:

version: 1
task_definition:
  task_execution_role: ecsTaskExecutionRole
  ecs_network_mode: awsvpc
  task_size:
    mem_limit: 0.5GB
    cpu_limit: 256
run_params:
  network_configuration:
    awsvpc_configuration:
      subnets:
        - subnet-abcd1234
        - subnet-dbca4321
      security_groups:
        - sg-abcd1234
      assign_public_ip: ENABLED

Command:

ecs-cli compose --project-name hello-world --file hello-world.yml --ecs-params ecs-params.yml --region us-east-1 create --launch-type FARGATE

Output:

INFO[0000] Using ECS task definition                     TaskDefinition=ecscompose-hello-world:5
