InformationEnsure that the etcd data directory ownership is set to etcd:etcd.
etcd is a highly-available key-value store used by Kubernetes deployments for persistent storage of all of its REST API objects. This data directory should be protected from any unauthorized reads or writes. It should be owned by etcd:etcd.
SolutionOn the etcd server node, get the etcd data directory, passed as an argument --data-dir, from the below command:
ps -ef | grep etcd
Run the below command (based on the etcd data directory found above). For example,
chown etcd:etcd /var/lib/etcd
By default, etcd data directory ownership is set to etcd:etcd.
