Hello all,
i have 3 master node and 4 worker node and cluster components are:
deployments, pods, services, PVs, PVCs, Kafka and elastic search.
i want to ask what is best way to how to upgrade the containerd version without impacting the system without downtime and fail of any components and care of elastic search and kafka?
Note: I don’t have enough resources.
You aren’t going to be able to do it without downtime if there is not enough space on other nodes that you can drain each node completely to update the containerd on it.
