I’m running Phoenix 1.7.11 on Kubernetes hosted on Azure. After deploying a new version, my app seems to be stuck in a loop, continuously reloading.
When I inspect the network traffic using Developer Tools, I consistently see the following behavior:
This issue has occurred 2-3 times immediately after deploying a new version. In each case, the problem resolved itself after a few hours.
Does anyone know how to prevent this from happening? I’ve tried signing in and out of the app, but that didn’t help. However, if I start an Incognito session, the app works fine.
I’ve configured Kubernetes to run 2 pods of my application. I tried scaling down to 1 pod to see if it would make a difference, and it worked! What considerations should I keep in mind to make it work with multiple pods?
No errors are reported, and the logs don’t reveal anything unusual:
