Hi,
I have a legacy app that doesn't support distributed session store (like redis), so we currently have it behind HAProxy (active/passive approach) in order to proceed with rolling updates.
- We deploy the new version to the passive server
- We set active server to drain, but still receiving the current sessions
- All the new requests go to backup server
- When active server is drained, we deploy the new version of the app and put it back online.
Is there a way to achieve this with Traefik? I was looking at wrr but not sure how to mix this with sticky sessions.
Cheers.
