Hi,
I'm currently trying to create a persistent instance of jenkins and I can't
make sense of the documentation about permissions on Persistent Volumes.
I first attached a new Disk on my VPS, called /dev/vde
then here's what I did
mkfs -t ext3 /dev/vde
Then mount it:
mount -t ext3 /dev/vde /var/lib/jenkins
chmod -R 777 /var/lib/jenkins
Create the persistent volume:
oc create -f ...
kind: PersistentVolume
apiVersion: v1
metadata:
name: jenkinsdata
labels:
type: local
spec:
capacity:
storage: 20Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "/var/lib/jenkins"
I can see that the the volume has rightly been claimed by the jenkins pod:
oc get pvc
NAME LABELS STATUS VOLUME
CAPACITY ACCESSMODES AGE
jenkins template=jenkins-persistent-template Bound jenkinsdata 20Gi
RWO 39m
but I'm seeing Permission errors in the deployment logs:

I thought that setting the permissions to 777 would guarantee that anyone can
do anything with the files under /var/lib/jenkins but that is apparently not
the case. Of course, ideally I would know what user and group is going to want
to use this directory but I have trouble finding out about this, especially
since the user is running from within the jenkins container (to be honest this
*really* gets me confused).
Any clues, pointers,...?
