            Just an update - turns out it was a problem with the code/configuration. I think it was called launchsetting.json file, which forcefully made the connection a HTTPS and forward it to the wrong port. Just had to remove that section and all was good.

            Kubernetes nginx ingress controller is unreliable
            Asked 2022-Mar-13 at 06:38

            I need help understanding in detail how an ingress controller, specifically the ingress-nginx ingress controller, is supposed to work. To me, it appears as a black box that is supposed to listen on a public IP, terminate TLS, and forward traffic to a pod. But exactly how that happens is a mystery to me.

            The primary goal here is understanding, the secondary goal is troubleshooting an immediate issue I'm facing.

            I have a cluster with five nodes, and am trying to get the Jupyterhub application to run on it. For the most part, it is working fine. I'm using a pretty standard Rancher RKE setup with flannel/calico for the networking. The nodes run RedHat 7.9 with iptables and firewalld, and docker 19.03.

            The Jupyterhub proxy is set up with a ClusterIP service (I also tried a NodePort service, that also works). I also set up an ingress. The ingress sometimes works, but oftentimes does not respond (connection times out). Specifically, if I delete the ingress, and then redeploy my helm chart, the ingress will start working. Also, if I restart one of my nodes, the ingress will start working again. I have not identified the circumstances when the ingress stops working.

            Here are my relevant services:

            I found the answer to my question here: https://www.stackrox.io/blog/kubernetes-networking-demystified/ There probably is a caveat that this may vary to some extent depending on which networking CNI you are using, although everything I saw was strictly related to Kubernetes itself.

            I'm still trying to digest the content of this blog, and I highly recommend referring directly to that blog, instead of relying on my answer, which could be a poor retelling of the story.

            If you don’t have access through ssh at your vm, you could use the serial port to login

            1. Go to the VM instances page in Google Cloud Platform console.
            2. Click on the instance for which you want to add a startup script.
            3. Click the Edit button at the top of the page.
            4. Click on ‘Enable connecting to serial ports’
            5. Click Save and then click RESET on the top of the page. You might need to wait for some time for the instance to reboot.
            6. Click on 'Connect to serial port' in the page.

            If you don’t have a root password for the serial console, you could use a startup script to add it to your instance, the script would be like this:

            1. Go to the VM instances page in Google Cloud Platform console.

            2. Click on the instance for which you want to add a startup script.

            It looks like the answer is to implement "ping pong". This prevents the firewall or proxy from terminating the connection.

            If you ping a websocket (client or server) then the specification says it has to respond (pong). But Javascript websocket depends on the browser implementation so it is best to implement a 30 second ping on the server to all clients. e.g.

            It looks like you have a container configured to bind mount /var/lib/docker.sock and the daemon restarted that container before creating the socket. There's been some tweeks to packaging in recent releases to reduce this chance. Otherwise you may want to mount the entire directory instead of a single file.

            To fix, try stopping docker, deleting the empty directory, and restarting docker to see if the socket gets created first (it's a race condition).
