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?
Sure, big orgs do it all the time. A pair of load balancers with virtual IPs that route traffic, either to a reverse proxy or right to the endpoint.
But your router is still a SPOF, as is your ISP.
How much availability is worth the time spend setting up and maintaining this, though?
