kubernetes mysql chown operation not permitted
I am currently experimenting with Kubernetes and have installed a small cluster on ESX infra I had running here locally. I installed two slave nodes with a master node using Project Atomic with Fedora. The cluster is all installed fine and seems to be running. However I first want to get a MySQL container up and running, but no matter what I try i cannot get it to run.
apiVersion: v1 kind: Pod metadata: name: mysql labels: name: mysql spec: containers: - resources: limits : cpu: 0.5 image: mysql:5.6 name: mysql env: - name: MYSQL_ROOT_PASSWORD value: myPassw0rd ports: - containerPort: 3306 name: mysql volumeMounts: - name: mysql-persistent-storage mountPath: /var/lib/mysql volumes: - name: mysql-persistent-storage nfs: server: 10.0.0.2 path: "/export/mysql"
For the volume I already tried all kinds of solutions, I tried using persistent volume with and without claim. I tried using host volume and emptyDir, but I always end up with this error when the container starts:
chown: changing ownership of ‘/var/lib/mysql/’: Operation not permitted
I must be doing something stupid, but no idea what to do here?

Ok it seems I can answer my own question, the problem was lying in the NFS share that was being used as the persistent volume. I had it set to ‘squash_all’ in the export but it needs to have a ‘no_root_squash’ to allow root in case of docker container to chown on the nfs bound volume.
