Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

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.
Podman definitely isn't a drop in replacement, it's like 90% there.
I’ll consider it a drop-in replacement when Kubernetes can use it.
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.
