Is there a possibility that these are going to exceed 1MB? Do you also need a procedure to maybe build derived heat containers that have the custom modules built in?

I have a feeling I worked on a Jira related to this and I listed a couple of options that I explored and tested. I have insufficient access to find that Jira now though unfortunately.

The largest plugin we've in repo (most complicated one, server.py) is 81,860 bytes, which is well under (7.8% of 1 MiB) etcd limit and they can use multiple configmaps for different plugins/files. I think we don't have to worry about it.

For larger files/folder (if can't use configmaps) there is the option of using a pvc.

I've added the option of using pvc for larger plugins in the docs now.
