I recently activated IPv6 on my Netcup VPS, and in the process of setting it up on all my LXCs I noticed that for “reasons” the IPv6 default route would vanish after starting Docker (switching it all over to Podman is on my TODO list), effectively breaking the IPv6 connectivity on this LXC.
How I Learned to Stop Worrying and Love the Rootless Container
I’ve been using nginx-proxy as a reverse proxy for my docker containers for a few years, where I manually generate and inject the necessary SSL certificates to make stuff work. The certificates were generated on my Opnsense box. A bit tedious, but manageable.
I’ve been moving some docker containers back from the VM I put them back to Linux Containers (LXC) because of I/O performance and cpu consumption reasons (caused by that I/O).
In the original design of my Proxmox box I opted for running the docker containers straight on the host. For a lot of reasons, this is actually a Bad IdeaTM, and it’s been one of my goals to migrate these to a VM at some point.
