Stop all ECS Cluster tasks with AWS CLI

Self answers:How to stop all tasks on a cluster with a single cli command, easily allowing for extra parameters to be passed.

Solution

  • The below will:

    1. Get all the tasks in the cluster
    2. Select the task arns using jq, -r removes the quotes from the json value.
    3. Pass each arn to the next command using xargs, the value is appended to the command (after --task). n-1 just ensures there is one command per arn, not sure if necessary.

    aws ecs list-tasks --cluster "$ecs_cluster" | jq -r ".taskArns[]" | xargs -n1 aws ecs stop-task --no-cli-pager --cluster "$ecs_cluster" --task

    --no-cli-pager prevents the output from stop-task from getting stuck after each execution.

    Any optimization welcome. I saw another solution with awk but found it hard to use with passing extra params to the second command.
