I installed a docker, Anonaddy, from Docker Hub via CA.

 

The docker appears installed correctly, and the docker starts.

 

However, the docker exits, and does not stay started/active.

 

How do I keep the docker active so I can log into it?

Looking at the sources 10-config.sh will exit with 1 if the database connection fails. 

Thanks.  I'll check into the 10-config.sh.

 

Also, I added this to my "Extra Parameters":  --interactive --tty

 

Next, I'm trying to figure out how to retain the docker's content after I update the Unraid config.  It seems Unraid wants to recreate the docker, and then I lose whatever I had.

10-config.sh isn't something you have access to, I was looking at the source of that container to see what could make it error out, and it exiting suggests you don't have the database configured correctly.

Nothing should be stored in docker, if that happens it also means something is configured wrong.

 

What template is it and what did you set up in there, post a screenshot.

I'm trying out two dockers that don't exist in CA, so it is a custom template. 

To make it simpler, I'm now trying just a simple Python container.

If I make any Unraid configuration changes to the docker, Unraid gives me a new container ID, and I lose whatever I did within the container.  I tried "committing", but that didn't seem to work either.

That's how it is supposed to be, docker containers should be considered read-only and disposable, anything you write should be in a volume.

okay...I created and mounted a docker volume to the docker container.  Within the container, it looks to be similar to using Unraid's "container path".

 

What do I need to do if I want to install software (e.g. nano), and retain it?

That should be done at the creation of the Docker image. Dockers are meant to be single purpose things, you create a Docker image with exactly what you need and nothing more for the one application it's meant to run, map any data it's intended to store to volumes mappings and never touch anything system-level in it again. If you need something else you create another image.
