[ENHANCEMENTS] Load Balancing or actif/Backup

[barto95100]

For example, I have proxmox cluster and all the node in cluster responde to access the GUI

if i configure zoraxy to send in backend node A and node A not respond (because is down or other) no access of proxmox gui bedhin zoraxy

Maybe possible to add a mechanism to load balancing or priorize to send backend for url (front) proxmox.localdomain.local to node A first and node B in second or in roud-robin node-A/node-B

mechanism to detect node-A and/or node-B is alive with ping or with http-request (the same of uptime)

@barto95100 I really have no idea what you mean. Can you use the proper ENHANCEMENT template for raising issues?
From what I can understand, you are ask for a load balance options for proxmox? Isn't proxmox a VM supervisor? And why the current setup won't work and what have you tried?

In proxmox you can setup a cluster of multiple nodes.

Every node has the ability to host the full web GUI for the entire cluster.

So if you have pve1.domain.com, pve2.domain.com, pve3.domain.com. they're saying that they want zoraxy to be smart enough to serve pve.domain.com and front any of pve1, pve2, or pve3... So for example try pve1... if it fails try pve2.... Or roundrobin trying all of them. pve1 for first request, pve2 for next...

Now it won't work the way they want it to... cause the states don't track well across the nodes, but it's an example.

The fail over option would be nice... if PVE1 is down then automatically serve to pve2.

if there is a testing mechanism (like HAproxy could do) to check whether or not the node responds to the ping or to an Http request with the code 200, then zoraxy could send in load-balancing our with a priority chosen by the 'user on this or that node of the cluster, this is an example, this could also be used for example with docker swarm (since all nodes respond to the ports of all containers/services)

Hi @barto95100 ,

I have tried proxmox with zoraxy a while back and proxmox always return 501 when I try to start stop the VM. How do you get around that? Are there any solutions other than sitting an Nginx proxy in between zoarxy and proxmox?

I cannot implement this feature if this was not solved, so any inputs will be welcomed. Thanks!

I check if i trace the problem with tcpdump or other tool

I believe this is what the request meant to implement.
