Love keeping that old tech alive! My Core 2 Duo died a couple of years back, if I could figure out a way to leverage old mobile phones for some sort of project I would.
Docker is still what 95% of people think of when you talk containers and you may encounters issues, particularly running things rootlessly as it's not a use-case that developers necessarily support.
Not to discourage you at all, experimentation is great, but be prepared for thorns. 👍
Mainly selected podman for the security, it doesn't rely on a daemon and supported rootless containers before docker did. Easy to just come up with a pattern where you can minimise the risk of container breakout by having a user for each container stack to provide even more isolation. You can do the same with docker these days I think, each user just runs their own copy of the docker daemon.
The aim of the project was to achieve 1:1 compatibility, I think it's pretty close these days.
It's also native to the Redhat family so could avoid using the community edition of Docker.
It really comes down to what value you assign to having private email storage.. unless you're having GPG encrypted convos, its probably pretty moot anyway as one side is going to have a copy of the email trail and theres a 98% probability its google, microsoft or ...yahoo I guess?
I might be talking myself out of this, this is now a therapy session
Totally respect that, I question my sanity frequently
