I want to set up a pod and there are two containers running inside the pod, which try to access a mounted file /var/run/udspath. In container serviceC, I need to change the file and group owner of /var/run/udspath, so I add a command into the yaml file. But it does not work.

kubectl apply does not complain, but container serviceC is not created. Without this "command: ['/bin/sh', '-c', 'sudo chown 1337:1337 /var/run/udspath']", the container could be created.
