I’m using a Docker image for PandoraFMS network monitoring. It has a separate docker container for the database and that one has a volume attached, but the main one doesn’t.
Apparently they release frequent updates; you’re just supposed to pull the latest and go. But it also requires a small amount of shell customization; editing config files and so on.
I’m no Docker expert; is there any way to update to a new image and retain or redo my customizations? How do people generally deal with this?
