Comment on Does it ever make sense/is it possible to move certain docker volumes to another physical volume, but not all?

I don’t know if this is naughty but I use bind mounts for everything, and docker compose to keep it all together.

You can map directories or even individual files to directories/files on the host computer.

Normally I make a directory for the service then map all volumes inside a ./data directory or something like that. But you could easily bind to different directories. For example for photoprism I mount my photos from a data drive for it to access, mount the main data/database to a directory that gets backed up, and mount the cache to a directory that doesn’t get backed up.

Same, I don’t let Docker manage volumes for anything. If I need it to be persistent I bind mount it to a subdirectory of the container itself. It makes backups so much easier as well since you can just stop all containers, backup everything in ~/docker or wherever you put all of your compose files and volumes, and then restart them all.

  Yes that’s what I do too!
  
  Overnight cron to stop containers, run borgmatic, then start the containers again.

I’ve never not used bind mounts. That data is persistent. Nonpersistent data is fine on docker volumes.

  Docker wants you to use volumes. That data is persistent too. They say volumes are much easier to backup. I disagree, I much prefer the bind mounts, especially when it comes to selective backups.

    Volumes are horrible, how would I easily edit a config file of the programm running inside, if the container deosnt even start.
    
    Bind mounts + ZFS datasets are the way to go.

I do that, until some container has permissions issues.
I tinker, try and fix it, give up and use a volume. Or I fix it, but it never seems to be the same fix

  I occasionally have had permissions issues but I tend to be able to fix them. Normally it’s just a matter of deleting the files on the host and letting the container create them, though it doesn’t always work it usually does.
