OKD Continued

Storage

• NFS storage for persistant volumes is provided by another host

General use PV example

• label can be used to easily tie a PV to a specific pod
• change capacity to your desired size
• change accessModes to your desired setting
• change nfs path and server to match your environment
• change persistentVolumeReclaimPolicy to your desired mode

pv-example.yml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: PV
  labels:
    project: any
spec:
  capacity:
    storage: 5Gi
  accessModes:
  - ReadWriteOnce
  nfs:
    path: /srv/oci/nfs/PV
    server: 192.168.122.1
  persistentVolumeReclaimPolicy: Recycle

sed one liner to create multiple PV definitions

for i in $(seq -w 001 020); do cp pv-example.yml pv${i}.yml; sed -i "s/PV/pv${i}/g" pv${i}.yml; done

create the PVs in OKD

for i in `ls pv0*yml`; do oc create -f ${i}; done

Cleaning up Evicted pods

for project in $(oc get projects | awk '{print $1}'); do for evicted in $(oc get pods -n ${project} | grep "Evicted" | awk '{print $1}'); do oc delete pod ${evicted} -n ${project}; done;  done
