wordpressdemo

This is a demo of running WordPress in OpenShift 4.x for students at the DevOps Engineer programme at Lernia education in Alvik, Bromma, Stockholm, Sweden.

The namespace

The namespace is set in namespace.yaml choose what you want and create it:

$ oc apply -f namespace.yaml

Then use the namespace:

$ oc project myNameSpace

MariaDB

WordPress

You need to create the PVC, and then mount it as /data. Start the Wordpress pod and copy files from /opt/app-root/src/ to /data. Change the mountPath in wordpress-deployment.yaml to /data:

        volumeMounts:
        - name: wordpress-data
          mountPath: /data

Delete the deployment and restart it:

$ oc delete deployment/wordpress
$ oc apply -f wordpress-deployment.yaml

Now find the name of the wordpress pod:

$ oc get pod
NAME                         READY   STATUS    RESTARTS   AGE
mariadb-77fdb58778-jwxp4     1/1     Running   0          61m
wordpress-764f45dbcf-6mqt8   1/1     Running   0          61m

In this example the pod is named wordpress-764f45dbcf-6mqt8, yours will be different!

Connect to the pod:

$ oc rsh pod/wordpress-764f45dbcf-6mqt8

In the pod you run:

$ cp -R /opt/app-root/src/* /data/
$ exit

Delete the wordpress pod and change Deployment configuration so it volume mounts the pvc in /opt/app-root/src/ folder instead.

        volumeMounts:
        - name: wordpress-data
          mountPath: /opt/app-root/src

Apply the deployment:

$ oc apply -f wordpress-deployment.yaml
