AWS Batch: How to enable ECS Exec?

AWS Batch does not currently support ECS Exec functionality. If you'd like this feature, I'd recommend you reach out to your AWS account team so they can inform the service team of your request.

In the meantime, if you use an EC2 compute environment, you can log into your EC2 instances and access your Batch-manged containers via the docker exec command.

Someone who downvoted my answer, then please explain why could I actually ECS Exec into my Batch container?

Hi, this documentation shows that you can run a task with ECS Exec enabled by running run-task command with --enable-execute-command.

However, you need to override the command to make the task persist long enough for you to debug. For example, if your batch runs java MyMainTask, you need to override the command to sleep infinity and run your program manually in the execute-command session.
