Unlike virtualization, in modern containerization technologies Kubernetes or Openshift doesn't include embedded storage with containers. Altough a standard vm contains embedded storage due to requirement of operation systems, already comes with virtual disks and it's storage space. In Kubernetes, Openshift and other variants, as an Administrator, you need to preconfigure the storage for for your containers/pods. You or your administrator needs to provide your node to persistent storage space(s). This spaces can be traditional block storage (iscsi, fc), file storage (cifs,nfs) or cloud storage (s3,azure files,ebs). Whatever technology you use, you need a Persistent Volume Claim (PVC) to provide persistent storage space to containers. As a first task, I recommend you to create a resource quota for your PVC to limit exhausting storage space. I'm going to tell openshift to limit "the project" or "namespace" to use total 500GB storage space and maximum al...
