02/24/2023, 10:42 PMno downtime to what
workload pods keep running while the service is restarted, but the kubelet/apiserver/etc will temporarily go away as they are upgraded.
If you follow the docs and upgrade only a single server at a time you should be fine

02/24/2023, 10:50 PMno problem yet. Our current upgrade is being run from ansible playbook and doing this simultaneously is causing downtime. A new feature is ask for a no downtime during the upgrade

02/24/2023, 10:51 PMyeah, you definitely don’t want to just have ansible just do all the nodes at once. Best practice is to do servers one at a time, waiting for everything to stabilize before moving on to the next. Then you can do the agents with as much parallelism as you want.
