cluster03: Proof of Concept with User Applications
After having successfully implemented a K8s-based storage cluster for inter-cluster NFS shares with Rook-NFS, I naturally wanted to use these 3 volumes in a separate K8s cluster dedicated to user applications.
But first of all I had to implement three instances of the nfs-client from the K8s incubator.
This time I did not use the helm chart version of nfs-client-provisioner.
I made three copies of the nfs-client deploy directory and adapted the YAML files appropriately.
After these preparations I could start deploying some stateful user applications via helm charts to my application cluster. I've used metalLB again, to get an externally accessible IP address for the helm apps.
