Take out volume mount for mig/ directory in production about docker-migrid HOT 4 OPEN

One addition:

The checked out version should maybe be visible in the mig/ directory, not just inside the home directory in the container

Sorry for the slow response - vacation and other tasks kept me busy :-/

I'm not sure I have the full overview of the consequences of the proposed modification, but am not generally averse to the idea. Currently I usually end up using complete docker clean on dev and test sites because of various docker/podman caching issues, possibly including the mentioned one.

One possible problem is the fact that both the mig and httpd dirs/volumes contain generated configuration files implicitly bound to a specific migrid version. That is, I guess we can potentially run into similar issues with the httpd volume being out of sync with the running migrid version.

So maybe we should not only remove the mig volume but also the httpd volume in production?

Well, at least that's what I suppose we might end up having to do if so. I'm just not sure if this will drag us down the way to restructuring everything to use a separate configuration volume setup or something, as we discussed previously here but put on hold for various reasons. If anybody can find time to look into the matter it would be welcome of course.
