Okay thanks, hoped there was a more efficient way. From: [email protected] Date: Thu, 10 Mar 2016 17:06:48 -0500 Subject: Re: Run Docker on Jenkins in OpenShift To: [email protected] CC: [email protected]; [email protected]; [email protected]
instead of building a new jenkins image to change the user, you should be able to just set the RunAsUser to "0" in the pod template (either PodSpec SecurityContext or Container SecurityContext), in the same place you set Privileged to true.

I tried it first with the template but didn't succeed because the image of the template is using uid 101 which hasn't root acces. You need to have root access to use Docker or create a docker group. So I had to change the image: Dockerfile: FROM docker.io/openshift/jenkins-1-centos7 USER 0 Copied the content of the template in a .yaml and edited the image. I had to delete the 'trigger' part and I had to set privileged: true in the template. Here are the mounts + I also mounted the /etc/origin/node/ca.crt to authenticate with Jenkins on my OpenShift (I push images to my OpenShift registry) privileged: true terminationMessagePath: /dev/termination-log volumeMounts: - mountPath: /var/lib/jenkins name: jenkins-volume - mountPath: /var/run/docker.sock name: socket - mountPath: /usr/bin/docker name: bin - mountPath: /cert/ name: cert dnsPolicy: ClusterFirst restartPolicy: Always securityContext: {} terminationGracePeriodSeconds: 30 volumes: - name: jenkins-volume persistentVolumeClaim: claimName: jenkins-claim - hostPath: path: /var/run/docker.sock name: socket - hostPath: path: /usr/bin/docker name: bin - hostPath: path: /etc/origin/node/ name: cert test: false triggers: - type: ConfigChange status: details: causes: - type: ConfigChange latestVersion: 11 last step is to edit the scc privileged: $ oc edit scc privileged: users: - system:serviceaccount:openshift-infra:build-controller - system:serviceaccount:management-infra:management-admin - system:serviceaccount:default:router - system:serviceaccount:default:registry - system:serviceaccount:jenkins:default Now my jenkins is persistent and I'm able to build docker images and push it into my own openshift registry.
