How to alter GitHub Docker-Compose.yml To use Informix DB for Portus?

Question

I am attempting to make a secured repo for our internal docker registry. Github has a ready to go docker-compose however it is using MariaDB and Postgres as highlighted below.

What would be the best practice to utilize the same informix container to run 2 databases for the frontend and backend support of Portus & Docker Registry.

I feel I have to post the entire docker-compose yaml for context. I am also not clear on if i really need Clair for anything.

I am running this on a Open SUSE Leap 15 system. Thank you!

I have been messing around with this and as its written the registry and portus will not connect for some reason, but the underlining Databases seem to work fine and those are a bigger concern at this moment.

The databases seem to run fine but I am still what i would consider a novice with docker-compose and informix on the setup side.

Any pointers or documentations recommendations would be most helpful as well.

unfortunately, Portus does not support informix DB. see this link
