Hi, I am kind of new to Docker but have quite a lot of containers running nonetheless and love it!
There is something I can't get my head around though, and I hope someone can explain this.
When I run a container from an image, and set a lot of start options/environment variables, these are visible in the details of the running container. My question is, where are these saved? Are they saved to a Dockerfile somewhere?
When Watchtower starts to update images and re-create containers, it knows what run options and environment variables to set, so it must get them from somewhere, right?
