如何删除 AWS ECS 任务定义？

Question

在 Amazon 的 EC2 Container Service 中创建任务定义后，如何删除或移除它？

Answer 1

It's a known issue . Once you de-register a Task Definition it goes into INACTIVE state and clutters up the ECS Console.

Answer 2

I've recently found this gist (thanks a lot to the creator for sharing!) which will deregister all task definitions for your specific region - maybe you can adapt it to skip some which you want to keep: https://gist.github.com/jen20/e1c25426cc0a4a9b53cbb3560a3f02d1

You need to have jq to run it: brew install jq

I "hard-coded" my region, for me it's eu-central-1 , so be sure to adapt it for your use-case:

#!/usr/bin/env bash
get_task_definition_arns() {
    aws ecs list-task-definitions --region eu-central-1 \
        | jq -M -r '.taskDefinitionArns | .[]'
}

delete_task_definition() {
    local arn=$1

    aws ecs deregister-task-definition \
        --region eu-central-1 \
        --task-definition "${arn}" > /dev/null
}

for arn in $(get_task_definition_arns)
do
    echo "Deregistering ${arn}..."
    delete_task_definition "${arn}"
done

Then when I run it, it starts removing them: Deregistering arn:aws:ecs:REGION:YOUR_ACCOUNT_ID:task-definition/NAME:REVISION...

Answer 3

您可以像以下命令一样取消注册（删除）任务定义： aws ecs deregister-task-definition --task-definition task_defination_name:revision_no

Answer 4

Oneline approach inspired by Anna A reply:

aws ecs list-task-definitions --region eu-central-1 \
  | jq -M -r '.taskDefinitionArns | .[]' \
  | xargs -I {} aws ecs deregister-task-definition \
        --region eu-central-1 \
        --task-definition {} \
  | jq -r '.taskDefinition.taskDefinitionArn'

Answer 5

Created following gist to safely review, filter and deregister AWS task-definitions and revisions in bulk (max 100 at a time) using JS CLI.

https://gist.github.com/shivam-nagar/aa79b02b74f616f8714d51e419bd10de

Can use this to deregister all revisions for task-definition. This will result in task-definition itself marked as inactive.
