Lispy Dobby writes that Nextcloud is a bit hostile with containers and that some features might not work. Do you think I could install Nextcloud groupware / LibreOffice Online / Nextcloud Talk inside the Nextcloud container?
Those will run fine for the most part. Once you have it running you can go to the “App” page and install them. Depending on the image you use, there will be some errors about an optional library not being installed, and some apps might want some additional packages installed in the image. If this is the case and they’re important enough that you want them, you can build the image yourself.
I just installed Red Hat Enterprise Linux 8.4 and Cockpit on a small server (an Intel NUC). Maybe I can create the same setup as mentioned in the article ‘Installing Nextcloud 20 on Fedora Linux with Podman’ with Cockpit (Cockpit has a Podman application)? Of course I could always use the command-line.
This will work just fine. I have mine running on Fedora 34 on a dual core Intel Atom board with 4GB of RAM I bought in like 2009. RHEL 8.4 ships with podman 3 so it does everything you need it to do. For the most part, there’s only a few podman commands you need to get familiar with to get started:
This lets you manage the images you have store locally:
podman image ls | rm | pull
This lets you look up and manage your containers that have been created from the downloaded images:
podman container ls | ps | logs | start | stop | rm
To lookup and manage your volumes for persistent storage:
podman volume ls | create | remove
And to get more info about any of the above items there is inspect:
podman inspect image | container | volume | network | pod
There’s also stuff for networks and pods too, but I’d recommend starting with the above. Inspect works with them as well:
