MediaCMS on Portainer

Has anyone tried to get MediaCMS setup on portainer, I love the YouTube style layout and it would be awesome for my non-plex style content. Been trying to build it on a stack from the docker compose having constant issues with missing files like entrypoint.sh that cant be called when building the system. Open to any ideas if someone got it running on the homelab via portainer?

Or interested in Alternatives similar setups. I already have plex, but I want to host work related content separate on this, so I have my own private offline YouTube of tutorials I like and need. I want to use it to host other video content like family videos and just memories and stuff for my home network, again separate from plex. I have so I want this to be offline self-hosted for that reason and privacy.
