Open myselfghost opened this issue 1 year ago • 2 comments

Which command or component

I am the maintainer of a production cluster and I have some questions about the maintenance of the production cluster.

Detailed description of the feature

  1. How to upgrade the version without loss, such as upgrading from 1.23.x to 1.24.x ？
  2. In a production cluster, we wan to optionally add additional SANs (hostnames or IPs) to the API server PKI certificate,how to update ?

  1. you can use Clusterfile sealos to support all the kubeadm config in Clusterfile

  2. In the feature, just change the image name in Clusterfile and reapply it, sealos will upgrade the cluster (in developing)

@fanux I'm not talking about the first installation, I just use SANs as an example, how to adjust the parameters after installation in a production cluster.
