It has an ‘App store’ that’s been growing a lot lately. Writing new docker-compose.yaml files is easy (see: https://www.runtipi.io/docs/contributing/adding-a-new-app ), and exposing them behind NAT, e.g. from home it’s easy too (see: https://www.runtipi.io/docs/guides/expose-apps-with-cloudflare-tunnels )… But my favorite perk is the folder structure (see: https://www.runtipi.io/docs/reference/folder-structure ), and the fact that ‘media’ is shared between apps.
To be clear, you have a (user:group) 1000:1000 on both containers? What about having the same mapping of Uid and Gid on the host? I assume the host is a desktop distro, and they usually have it already. You would require the three, so that permissions are “coherent” between each system
