So, just for the sake of it I’ve been trying to get my lab to be HA -or as HA as a small homelab can be-

My current set up is a follows:

3 proxmox servers with some Debian VMs, the VMs run docker swarm

A NAS, with Truenas

ISProuter -> OpenWRTRouter -> VM [Port fowards 80/443]

This works like a charm when I am in my LAN, but when I access from outside, if the VM that has 80/443 port forwarded to is down (which it never is) I’d loose connectivity.

I have now idea how to solve this little problem in a efficient way, maybe a reverse proxy running on my OpenWRT? (Which’d only move the point of failure to my router, but if my router goes down is gameover already anyways) has anyone attempted this?

Any opinions/ideas?

Update:

Solved! I moved my traefik data to a NFS share in my NAS, replicated the container across all manager nodes and then installed keepalived and now float a VIP between them.

Works like a charm and it was super easy to set up, literally 3 ansible tasks and 1 jinja template and you are done.

Thanks to all of ya!

    You’re discovering that there’s ALWAYS a single point of failure. Even if every service is fault tolerant, you likely have a single network or power infrastructure. So, you have to figure out what you’re willing to tolerate. You could look into CARP or keepalived to make your reverse proxy more resilient. It’s probably overkill for a homeland, but could be a useful learning exercise.

      I remember a TV station I worked at, that had a lot of good redundancies with 3 redundant UPSs that could keep a bunch of equipment on air until the big generator took over, one day had the UPS controller die and took all 3 UPSs out. I think it took the engineers a couple days to get everything back up and running.

      Def went into the rabbit hole without any idea how many of these single points I’d need to address, and the more I mitigate the more I find. Like you said, this is very much overkill, I am just doing it to learn and have some good old homelab fun before we are all forced to rent “cloud” PCs

      Thanks for the suggestions, I’ll look into those!
