You can also just copy your thunderbird profile directory, if it’s the same OS, to a different system and it seems to just work. I did this to copy the whole setup and synced mails from desktop to laptop. I also tried this from Windows -> Linux and it did not like that, so I used the import profile feature and re-entered all the passwords.

I’ve used Ansible to deploy docker compose and it worked pretty well. You will have to do some learning if you aren’t familiar with it, but I’d say it’s worth it.

Like others, I would not recommend Jenkins.
