1.4.8 Ensure that the etcd pod specification file ownership is set to root:root

Information

Ensure that the '/etc/kubernetes/manifests/etcd.yaml' file ownership is set to 'root:root'.

Rationale:

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'.

Solution

Run the below command (based on the file location on your system) on the master node. For example,

chown root:root /etc/kubernetes/manifests/etcd.yaml

Impact:

None
