The volumeMounts field in the StatefulSet's spec ensures that the /usr/share/nginx/html directory is backed by a PersistentVolume.\n\nWrite the Pods' hostnames to their index.html files and verify that the NGINX webservers serve the hostnames\n\nBounded code example (external data; do not execute automatically):\n```shell\nfor i in 0 1; do kubectl exec \"web-$i\" -- sh -c 'echo \"$(hostname)\" > /usr/share/nginx/html/index.html'; done\n\nfor i in 0 1; do kubectl exec -i -t \"web-$i\" -- curl http://localhost/; done\n```\n\nBounded code example (external data; do not execute automatically):\n```text\nweb-0\nweb-1\n```\n\nIf you instead see 403 Forbidden responses for the above curl command, you will need to fix the permissions of the directory mounted by the volumeMounts (due to a bug when using hostPath volumes), by running\n\nfor i in 0 1; do kubectl exec web-$i -- chmod 755 /usr/share/nginx/html; done\n\nbefore retrying the curl command above.\n\nIn one terminal, watch the StatefulSet's Pods\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
