My VPS Hobby Mail Server with Hetzner aged and decided to noob dive into LXD and put it on my root Server. Making this post in hopes to cut someone else’s research, try & error Time spend down.
Might be relieved to know that we do not need to touch Netplan configs.
Suggestions are welcome, my next step is to actually install a Mail Server in a container and see it running for a while without problems.
You will not be able to ssh or ping from Host to Container or from Container to Host.
