Hi
We have been running Rancher since 2.0.8 and are now on 2.1.3. Our use-case is primarily to deploy kubernetes clusters on our vSphere infrastructure.
To do that we use RancherOS 1.4.2 and 1.5.0 with vmware support (open-vm-tools).
Our, or my, question is now: How are we suppose to upgrade the OS of deployed machines in a cluster?
Are machines created in this way using “docker-machine” and by that affected by this?
If you are using
docker-machine
then you will not be able to upgrade your RancherOS version. You need to delete and re-create the machine.
If that is the case, what would be the recommended way to upgrade several 8-node clusters (3 etcd, 2 control pane and 3 worker)?
