Hello! I need a guide on how to migrate data from shared hosting to Docker. All the guides I can find are about migrating docker containers though! I am going to use a PaaS - Caprover which sets up everything. Can I just import my data into the regular filesystem or does the containerisation have sandboxed filesystems? Thanks!

    https://docs.docker.com/storage/volumes/

    Just move your data and then either create bind mounts to those directories or create a new volume in docker and copy the data to the volume path in your filesystem.

    I also suggest looking into podman instead of docker. Its basically a drop in replacement for docker.

          Not sure what you mean, Podman isn’t a container runtime and Kubernetes has deprecated it’s docker shim anyway.

          Kubernetes uses cri-o nowadays. If you’re using kubernetes with the intent of exposing your docker sockets to your workloads, that’s just asking for all sorts of fun, hard to debug trouble. It’s best to not tie yourself to your k8s clusters underlying implementation, you just get a lot more portability since most cloud providers won’t even let you do that if you’re managed.

          If you want something more akin to how kubernetes does it, there’s always nerdctl on top of the containerd interface. However nerdctl isn’t really intended to be used as anything other than a debug tool for the containerd maintainers.

          Not to mention podman can just launch kubernetes workloads locally a.la. docker compose now.

      Yeah I saw this post and thought “what a coincidence, I’m looking to move from docker!”

      Everybody’s going somewhere, I suppose.

        podman generate systemd really sold it for me. Also the auto update feature is great. No more need for watchtower.

          My one… battlefield with docker was trying to have a wireguard VPN system in tandem with an adguard DNS filter and somehow not have nftables/iptables not have a raging bitch fit over it because both wireguard and docker edit your table entries in different orders and literally nothing I did made any difference to the issue, staggering wireguard’s load time, making the entries myself before docker starts (then resolvconf breaks for no reason). Oh, and they also exist on a system with a Qbittorrent container that connects to a VPN of its own before starting. Yay!

          And that’s why all of that is on a raspberry pi now and will never be integrated back into the image stacks on my main server.

          Just… fuck it, man. I can’t do it again. It’s too much.

      Yes, I would set up the containers empty, then import your data however the applications want it. Either by importing via their web interface, or by dropping it in their bound directory.

        Thanks! So, here in the Capriver demo config for Wordpress path says: var/www

        This is the regular var/www? Not a different one for the Wordpress container?

        I would just simple put my current WP files (from public-html) in that directory?

        Do the apps all share a db?

      Thanks! I will have to research volumes! Bind mount - that would mean messing with fstab, yes? I set up a bind for my desktop but entering mounts in fstab has borked me more than once!
