Profile applicability: Level 1 - Master Node
Ensure that the /etc/kubernetes/manifests/etcd.yaml file ownership is set to root:root.
The etcd pod specification file /etc/kubernetes/manifests/etcd.yaml controls various parameters that set the behavior of the etcd service in the master node. etcd is a highly- available key-value store which Kubernetes uses for persistent storage of all of its REST API object. You should set its file ownership to maintain the integrity of the file. The file should be owned by root:root.
Note
Note
By default, /etc/kubernetes/manifests/etcd.yaml file ownership is set to root:root.
