AWS ECS 服务错误：必须启用任务长 arn 格式才能使用 ECS 托管标签启动服务任务

Question

I have a ECS service running in a cluster which has 1 task. Upon task update, the service suddenly died with error: 'service my_service_name failed to launch a task with (error Task long arn format must be enabled for launching service tasks with ECS managed tags.)'

Current running tasks are automatically drained and the above message shows up every 6 hours in the "Events" tab of the service. Any changes done to the service config does not repair the issue. Rolling back the task update also doesn't change anything.

I believe I'm already using the long ARN format. Looking for help.

Answer 1

This turned out to be a AWS bug acknowledged by them now. It was supposed to manifest after Jan 1 2020 but appeared early because of a workflow fault in AWS.

The resources were created by an IAM user who was later deleted and hence the issue appears.

我只是从我的任务 JSON 输入中删除了以下内容：propagateTags、enableECSManagedTags

Answer 3

It seems like you are Tagging Your Amazon ECS Resources but you did not opt-in to this feature so you have to opt-in and I thin you are using regular expression in deployment so if your deployment mechanism uses regular expressions to parse the old format ARNs or task IDs, this may be a breaking change.

Starting today you can opt in to a new Amazon Resource Name (ARN) and resource ID format for Amazon ECS tasks, container instances, and services. The new format enables the enhanced ability to tag resources in your cluster, as well as tracking the cost of services and tasks running in your cluster.

In most cases, you don't need to change your system beyond opting in to the new format. However, if your deployment mechanism uses regular expressions to parse the old format ARNs or task IDs, this may be a breaking change. It may also be a breaking change if you were storing the old format ARNs and IDs in a fixed-width database field or data structure.

After you have opted in, any new ECS services or tasks have the new ARN and ID format. Existing resources do not receive the new format. If you decide to opt out, any new resources that you later create then use the old format.

You can check this AWS compute blog to migrate to new ARN.

Tagging Your Amazon ECS Resources

To help you manage your Amazon ECS tasks, services, task definitions, clusters, and container instances, you can optionally assign your own metadata to each resource in the form of tags. This topic describes tags and shows you how to create them.

Important

To use this feature, it requires that you opt-in to the new Amazon Resource Name (ARN) and resource identifier (ID) formats. For more information, see Amazon Resource Names (ARNs) and IDs .
