One way to handle persistent container storage is to use a shared filesystem such as glusterfs or objectivefs. It's easy to set up and can be very helpful when moving your infrastructure to containers. Once created you can mount your shared filesystem either on the host and share it with the container or directly in the container, see e.g. https://objectivefs.com/howto/how-to-use-objectivefs-with-do...

If I understand correctly you are suggesting a block storage solution. But that would then prohibit a scale out, right? (I'm reading on the ObjectiveFS site that it does allow the concurrent access of shares... Hmmm.)

The other solution is object storage, which is the real way forward (IMHO). This route make a app more adherent to the 12-factor principles.

Both GlusterFS and ObjectiveFS are shared filesystems instead of block storage, so they work with POSIX files/directories (like NFS) making them easier to scale out. If your application can work directly with an object store that is of course also a great way to go.
