I just tested Ranche RKE , upgrading kubernetes 13.xx to 14.xx , during upgrade , an already running nginx Pod got restarted during upgrade. Is this expected behavior?
Can we have Kubernetes cluster upgrades without user pods restarting?
Which tool supports un-intruppted upgrades?
What are the downtimes that we can never aviod? ( apart from Control plane )
Resolved By configuring the container runtime on the hosts not to restart containers on docker restart.
