ECS task role chaining limitation to 1 hour

Question

A customer is running into an error when trying to take the current task role credentials to assume a different role beyond 1 hour. They run into this error message:
"ClientError: An error occurred (ValidationError) when calling the AssumeRole operation: The requested DurationSeconds exceeds the 1 hour session limit for roles assumed by role chaining."

I can't seem to find guidance on how a customer should configure the task role credentials duration beyond 1 hour so that assume role chaining can also extend beyond 1 hour. Is that possible?

Accepted Answer

I am just working on a container that ran into exactly the same issue. I made an assume role and added the credentials directly to the invocation of a third party lib. In the moment where the credentials timed out, all calls failed.

I found this merge request https://github.com/boto/botocore/pull/1313!

Now, I created a profile with the EcsContainer source:

[profile crossaccount]
    role_arn="${CROSS_ACCOUNT_ROLE_ARN}"
    credential_source=EcsContainer

I pass this profile to the 3rd party lib instead. Under the hood, this profile is registered in the credentials provider chain which solves the issue.

Best regards
