How do you build from devel and include custom_credential plugins?

I wrote a custom credential plugin and was able to get it working fine in the old non-container based installs of Tower.

While trying to also validate against the new AWX container-based installs I’ve been running into quite a few snags. The only way I’ve been able to get the AWX image to even build was off of devel… which doesn’t include any of the custom_credentials in awx/main/custom_credentials dir. I checked and don’t see these files in any of the containers that were built.

I’m assuming there is some extra build step required to populate those files, but don’t see any documentation around it.

Has anyone packaged any of their own custom credentials or know the process to do so?

Thanks!

EDIT: I did find the credential_plugins in the tools container… I’m just not sure how they were added or how I would include my plugin as well.

EDIT 2: While the credential plugins are visible on the filesystem, I don’t see all of them in the UI… Only the defaults are visible, but all the custom plugins such as “HashiCorp Vault Secret Lookup” or the other plugins are not visible…
