Hmm I want to "upgrade" my home #k8s cluster to either #Fedora #CoreOS or #RHCOS, and drop docker in favour of cri-o, but I'm not sure what they best way would be to go about it without too much down time. I'm not sure if you can mix container runtimes in #kubernetes?
Could just rebuild one host at a time if they can be mixed.

I consider myself a hardcore geek, but these days most of my time is taken up by my three kids and wife.
It's so frustrating that #kubernetes tries to do a chown recursively every time a pod starts up if you have fsGroup set. For a volume with a very large amount of files (eg minio!), it means the pod will take ages to start up.
Finally got my #kubernetes cluster back up. All I wanted to do was upgrade kubernetes, and add a few nodes with Fedora CoreOS, but it exploded in my face. Switched back to CentOS 7 for now.
I've been spending the last week going through a #RedHat training course for #OpenShift. I really want to switch my home #kubernetes cluster from K8S to OpenShift, but it would be problematic as I have very little RAM and CPU for my cluster.
It totals 16GB, and 4 CPU cores across two nodes, and the CPUs aren't great either (G1840T).
I want a couple of quad core i7/i5 NUCs to add to the cluster. If I come across some for a reasonable price, I will definitely be getting them.
