This concerns me too. What should I be worrying about? The main maintenance problem that I have experienced so far is that automatic major version updates can break the cluster (which is why I now keep back those packages). Are there other gotchas that I'm likely to experience?
- mrweasel 5y agoVersion updates don't normally break the cluster, in my experience, but it might break things like Helm charts. The thing that concerns me the most is managing the internal certificates and debugging networking issues.
- gnfargbl 5y ago> managing the internal certificates I haven't yet set it up, but https://github.com/kontena/kubelet-rubber-stamp https://github.com/kontena/kubelet-rubber-stamp is on my list to look at. > debugging networking issues In this regard, I have had much more success with flannel than with calico. The BGP part of calico was relatively easy to get working, but the iptables part had issues in my set-up and I couldn't understand how to begin debugging them.
