Amazon ECS examples using Amazon CLI

To create a capacity provider

The following create-capacity-provider example creates a capacity provider that uses an Auto Scaling group named MyASG, has managed scaling and managed termination protection enabled. This configuration is used for Amazon ECS cluster auto scaling.

aws ecs create-capacity-provider \
    --name "MyCapacityProvider" \
    --auto-scaling-group-provider "autoScalingGroupArn=arn:aws:autoscaling:us-east-1:123456789012:autoScalingGroup:57ffcb94-11f0-4d6d-bf60-3bac5EXAMPLE:autoScalingGroupName/MyASG,managedScaling={status=ENABLED,targetCapacity=100},managedTerminationProtection=ENABLED"

Output:

{
    "capacityProvider": {
    "capacityProviderArn": "arn:aws:ecs:us-east-1:123456789012:capacity-provider/MyCapacityProvider",
    "name": "MyCapacityProvider",
    "status": "ACTIVE",
    "autoScalingGroupProvider": {
        "autoScalingGroupArn": "arn:aws:autoscaling:us-east-1:132456789012:autoScalingGroup:57ffcb94-11f0-4d6d-bf60-3bac5EXAMPLE:autoScalingGroupName/MyASG",
        "managedScaling": {
            "status": "ENABLED",
            "targetCapacity": 100,
            "minimumScalingStepSize": 1,
            "maximumScalingStepSize": 10000,
            "instanceWarmupPeriod": 300
        },
        "managedTerminationProtection": "ENABLED"
    },
    "tags": []
}

Example 1: To create a new cluster

The following create-cluster example creates a cluster.

aws ecs create-cluster \
    --cluster-name MyCluster

Output:

{
    "cluster": {
        "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster",
        "clusterName": "MyCluster",
        "status": "ACTIVE",
        "registeredContainerInstancesCount": 0,
        "pendingTasksCount": 0,
        "runningTasksCount": 0,
        "activeServicesCount": 0,
        "statistics": [],
        "tags": []
    }
}

For more information, see Creating a Cluster in the Amazon ECS Developer Guide.

Example 2: To create a new cluster using capacity providers

The following create-cluster example creates a cluster and associates two existing capacity providers with it. The create-capacity-provider command is used to create a capacity provider. Specifying a default capacity provider strategy is optional, but recommended. In this example, we create a cluster named MyCluster and associate the MyCapacityProvider1 and MyCapacityProvider2 capacity providers with it. A default capacity provider strategy is specified that spreads the tasks evenly across both capacity providers.

aws ecs create-cluster --cluster-name MyCluster --capacity-providers MyCapacityProvider1 MyCapacityProvider2 --default-capacity-provider-strategy capacityProvider=MyCapacityProvider1,weight=1 capacityProvider=MyCapacityProvider2,weight=1

Output:

    "cluster": {

Example 4: To create a new service behind a load balancer

The following create-service example shows how to create a service that is behind a load balancer. You must have a load balancer configured in the same Region as your container instance. This example uses the --cli-input-json option and a JSON input file called ecs-simple-service-elb.json with the following content:

{
    "serviceName": "ecs-simple-service-elb",
    "taskDefinition": "ecs-demo",
    "loadBalancers": [
        {
            "loadBalancerName": "EC2Contai-EcsElast-123456789012",
            "containerName": "simple-demo",
            "containerPort": 80
        }
    ],
    "desiredCount": 10,
    "role": "ecsServiceRole"
}

Command:

aws ecs create-service \
    --cluster MyCluster \
    --service-name ecs-simple-service-elb \
    --cli-input-json file://ecs-simple-service-elb.json

Output:

{
    "service": {
        "status": "ACTIVE",

                "loadBalancerName": "EC2Contai-EcsElast-123456789012"
            }
        ],

                "taskDefinition": "arn:aws:ecs:us-west-2:123456789012:task-definition/ecs-demo:1",
                "updatedAt": 1428100239.123,
                "id": "ecs-svc/1234567890123456789",
                "runningCount": 0
            }
        ],
        "events": [],
        "runningCount": 0
    }
}

Example 1: To add an existing capacity provider to a cluster

The following put-cluster-capacity-providers example adds an existing capacity provider to a cluster. The create-capacity-provider command is used to create a capacity provider. The describe-clusters command is used to describe the current capacity providers and the default capacity provider strategy associated with a cluster. When adding a new capacity provider to a cluster, you must specify all existing capacity providers in addition to the new capacity provider you want to associate with the cluster. You must also specify the default capacity provider strategy to associate with the cluster. In this example, the MyCluster cluster has the MyCapacityProvider1 capacity provider associated with it and you want to add the MyCapacityProvider2 capacity provider and include it in the default capacity provider strategy so tasks are spread evenly across both capacity providers.

aws ecs put-cluster-capacity-providers \
    --cluster MyCluster \

Example 2: To remove a capacity provider from a cluster

The following put-cluster-capacity-providers example removes a capacity provider from a cluster. The describe-clusters command is used to describe the current capacity providers associated with a cluster. When removing a capacity provider from a cluster, you must specify the capacity providers you want to remain associated with the cluster as well as the default capacity provider strategy to associate with the cluster. In this example, the cluster has the MyCapacityProvider1 and MyCapacityProvider2 capacity providers associated with it and you want to remove the MyCapacityProvider2 capacity provider, so you specify only MyCapacityProvider1 in the command along with the updated default capacity provider strategy.

aws ecs put-cluster-capacity-providers \
    --cluster MyCluster \
    --capacity-providers MyCapacityProvider1 \
    --default-capacity-provider-strategy capacityProvider=MyCapacityProvider1,weight=1,base=0

Example 1: To register a task definition with a JSON file

The following register-task-definition example registers a task definition to the specified family. The container definitions are saved in JSON format at the specified file location.

aws ecs register-task-definition \
    --cli-input-json file://<path_to_json_file>/sleep360.json

Contents of sleep360.json:

{
    "containerDefinitions": [
        {
            "name": "sleep",
            "image": "busybox",

            "command": [
                "sleep",
                "360"
            ],
            "memory": 10,
            "essential": true
        }
    ],
    "family": "sleep360"
}

Output:

        "family": "sleep360",
        "placementConstraints": [],

    }
}

For more information, see Example task definitions in the Amazon ECS Developer Guide.

Example 2: To register a task definition with a JSON string parameter

The following register-task-definition example registers a task definition using container definitions provided as a JSON string parameter with escaped double quotes.

aws ecs register-task-definition \
    --family sleep360 \
    --container-definitions "[{\"name\":\"sleep\",\"image\":\"busybox\",\"cpu\":10,\"command\":[\"sleep\",\"360\"],\"memory\":10,\"essential\":true}]"

The output is identical to the previous example.

For more information, see Creating a Task Definition in the Amazon ECS Developer Guide.

To run a task on your default cluster

The following run-task example runs a task on the default cluster and uses a client token.

Example 1: To change the task definition used in a service

The following update-service example updates the my-http-service service to use the amazon-ecs-sample task definition.

aws ecs update-service --service my-http-service --task-definition amazon-ecs-sample

Example 2: To change the number of tasks in a service

The following update-service example updates the desired task count of the service my-http-service to 3.

aws ecs update-service --service my-http-service --desired-count 3

For more information, see Updating a Service in the Amazon ECS Developer Guide.

To update a task set

The following update-task-set example updates a task set to adjust the scale.

aws ecs update-task-set \
