Use `UpdateService` with an AWS SDK or CLI

The following code examples show how to use UpdateService.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code examples:

CLI

AWS CLI

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 \
    --cluster test \
    --service my-http-service \
    --task-definition amazon-ecs-sample

Output:

Example 3: To configure Amazon EBS volumes for attachment at service update

The following update-service example updates the service my-http-service to use Amazon EBS volumes. You must have an Amazon ECS infrastructure role configured with the AmazonECSInfrastructureRolePolicyForVolumes managed policy attached. You must also specify a task definition with the same volume name as in the update-service request and with configuredAtLaunch set to true. This example uses the --cli-input-json option and a JSON input file called ebs.json.


aws ecs update-service \
    --cli-input-json file://ebs.json

Contents of ebs.json:


{
   "cluster": "mycluster",
   "taskDefinition": "mytaskdef",
   "service": "my-http-service",
   "desiredCount": 2,
   "volumeConfigurations": [
        {
            "name": "myEbsVolume",
            "managedEBSVolume": {
                "roleArn":"arn:aws:iam::123456789012:role/ecsInfrastructureRole",

Example 4: To update a service to no longer use Amazon EBS volumes

The following update-service example updates the service my-http-service to no longer use Amazon EBS volumes. You must specify a task definition revision with configuredAtLaunch set to false.


aws ecs update-service \
    --cluster mycluster \
    --task-definition mytaskdef \

    --availability-zone-rebalancing ENABLED

Output:
