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?
Focus more on why the service is going down, and solve for that. Make it reliable by restarting automatically in the face of failures. A Reverse Proxy should be dead simple, and not change states between restarts, so it shouldn’t be dying in the first place. Having it restart on failures should be simple and reliable.
It never goes down :-) I just want to make it better.
Alright, im kind lying, it use to go down all the time cause my NICs would hang, but I did fix it. This problem did gave me the itch to make it even more avaliable.
There’s only so much reliability you can build into a simple home setup without it being a major loss on investment. In a datacenter situation, you’d have fault tolerance on all the network ingress: load balancers, bonded interfaces, SDWAN configurations…etc.
Unless you want 3 of everything you own, just do the basics, OR I guess consider hosting it elsewhere 🤣
