If you are using docker in this carefully assembled stateful way - you are doing it wrong. You should be using docker via scripts and IaaS tooling that will assert your desired setup from some kind of configuration. Meaning, you should be able to easily blow all of that away and recreate it with a single script. Likewise, a transition to podman should involve adjusting your scripts to re-assert that plan against podman instead of docker.

This is a cool tool for the decrepit hand-configured server with no documentation that has been running since 2017 untouched and needs an update... but I would encourage you to not fall into this trap to begin with.
