Summary

  • The Serverless Worker CloudFormation templates (Lambda invocation role, both Cloud and self-hosted) build the final IAM role name by concatenating RoleName and the stack name (<RoleName>-<StackName>).
  • IAM role names cannot exceed 64 characters, so a long RoleName or stack name can cause stack creation to fail.
  • Added a note to the RoleName parameter description in both deploy guides.

Test plan

  • yarn build passes with no new broken links or MDX errors

┆Attachments: EDU-6672 Note IAM role name length limit for CloudFormation stack

The template appends the stack name to RoleName to form the final IAM
role name. If the combined name exceeds the 64-character IAM limit,
stack creation fails.

This is a temporary caution; the note will be removed once the
underlying stack name length issue is resolved.
