An error occurred (ValidationError) when calling the CreateChangeSet operation: Template format error: Resource name batch_job_admin_group is non alphanumeric.

AWS Naming Conventions…again…CloudFormation

Apparently no names in CloudFormation can contain underscores. I don’t love camel case but that would work. In this case the problem was with one of my resource names.

So this:

Resources:
  batch_job_admin_group:
    Type: AWS::IAM::Group
    Properties:
      GroupName: !Ref group_name_param

Became this:

Resources:
  batchjobadmingroup:
    Type: AWS::IAM::Group
    Properties:
      GroupName: !Ref group_name_param

Just name everything on AWS all lowercase no spaces no underscores no dashes and no numbers. That should work. I think.
