Before upgrading to Rancher v1.2 we had Rancher v1.1.4 behind a AWS ELB with websockets and proxy-protocol setup. This worked fine and the UI was normal, however after upgrading to Rancher v1.2.2 the UI seems much more temperamental and unresponsive now. I don’t know if it’s the ALB or the 1.2 upgrade however.
- Switching Environments in the upper corner doesn’t work, and requires a full page refresh
- Stacks don’t refresh fully, and containers in the UI say “starting…” but looking at them from the docker cli shows them up and running
- Deployments seem much “slower”, with some stacks that used to come up in seconds in v1.1.4 taking minutes.
- Viewing JSON logs in the UI on a running container constantly says “Disconnected”. Occasionally the logs do show up, but it’s inconsistent. Getting a shell on a container works properly.
