Hello community,

I am feeling really bad that I didn‘t find this information, which I consider as really basic. Actually it is not about getting it up and running for the first time, but this category appears to me as closest cousin to my question.

Q: how to upgrade an existing installation through Docker?  
Background: I have used the in-app „update“ feature, which killed my Discourse instance. (I could specify if required).  
I am using a Debian 1-2 yrs old on a virtual host in the cloud (Hetzner).

So what I am looking for is to download a recent Docker image, build a container, but not losing my configuration (and data or course). I am not very skilled in Docker, so I do not trust myself to dive into it on my own.

I guess it is pretty simple, as this is part of the principle to use (unmutable or stateless) containers.

Thank you for your support.

Thomas
