Hello, I've some old projects that I'd like to maintain along new ones in my kubernetes cluster. I thought that the easiest way of doing that might be running said project inside one pod (docker in docker). Is that doable? Google searches don't yield any results, so there have to be some roadblocks :P I don't care about HA for those projects and just want to maintain one infrastructure instead of multiple ones.

EDIT. Thanks for the answers guys, I guess I'll spend some time to properly convert those compose files. Thanks for taking time to answer. Cheers :-)
