So…wait for it…I destroyed my postgres and web_only containers, bootstrapped them again and hang on..what’s that? My forum is still there?! I’m quite confused and I’m not sure what’s going on.

I always wanted a trivial to recover scenario, for example you can even recover data if docker completely fails and so on. destroy is a somewhat scary word, but it does re…

Thanks for your replies. I was already pretty confident with the Docker setup, I just wasn’t aware of the symlinked volumes and the data living on the host. Now I know! :slight_smile:
