Question: do proxmox nodes share auth token? about proxmoxer HOT 2 CLOSED

yes, if your nodes are in a cluster, load balancing across their API will work.

I tested this by creating 2 nodes (in VMs) and joining them together in a cluster. I then created a container on one node, installed nginx, and added the following to /etc/nginx/nginx.conf:

stream {
        upstream api_nodes {
                server 10.0.1.111:8006;
                server 10.0.1.112:8006;
        }

        server {
                listen 8006;
                proxy_pass api_nodes;
        }
}

using the container's IP address, I can access the web UI or use proxmoxer and the calls are evenly distributed between the two nodes. If I were actually doing this for continued use, I would add hash $remote_addr; to the upstream so connections from any give IP are tied to a specific node. This means all the traffic from your computer will go to one node, but multiple clients will be load balanced across the nodes.

I think load balancing individual requests between nodes is okay, but there might be weird race conditions or different responses that I haven't seen. I would try to tie connections (or at least chunks of requests) to a single node (like done above with the hash of the IP).

also note, this will only work when not verifying SSL certificates or updating the certificates on all nodes to allow the IP and/or hostname of the load balancer.
