Hoping someone can help me resolve what appears to be a permissions error. I'm trying to start a 3-node elasticsearch cluster using the official elasticsearch docker image. When the container was started I was getting an "access denied" error from elasticsearch on /usr/share/elasticsearch/data/nodes so I tried adding a command to make elasticsearch the owner of /usr/share/elasticsearch/data...but I get these errors when I include the chown command:

chown: cannot read directory '/usr/share/elasticsearch/data/lost+found': Permission denied
chown: changing ownership of '/usr/share/elasticsearch/data': Operation not permitted

Here is my statefulset yaml file:
