Thanks so much in advance for stopping in - I really appreciate it.
I am currently running v4 on a rack-mounted server that I got from a previous job. Besides using it as a file share for movies, shows, etc I am running several dockers (downloaders, plex, pi-hole, transmission/openvpn, etc) and a virtualbox server. I am not currently exposing anything outside of my network - I did try to get letsencrypt working but was not able to (I am hoping it was an issue with the version now that I solved a double nat issue).
Anyway, I have a free day tomorrow so I am considering upgrading to 5. I've watched the videos and read various threads. I know that virtualbox isn't supported - I can offload that windows pc onto something else. My biggest concern is having to rebuild the docker containers. I understand that docker is different in omv 5 - exactly how easy is it to bring them up in portainer? I see a lot of people asking that question but I haven't found a good answer.
A little more background. I am a software dev during the day and I am just dangerous enough to follow guides on how to do most things in linux. I've been meaning to spend a day learning how to create docker containers by hand but I haven't (yet) gotten around to it. Should I bother with the upgrade to 5? Should I wait for 6?
