Description

Self-signed certificates for TLS should not be used. Etcd is a highly-available key value store used by Kubernetes deployments for persistent storage of REST API objects. These objects are sensitive in nature and should not be available to unauthenticated clients. You should enable the client authentication via valid certificates to secure the access to the etcd service.

Remediation

Edit the etcd pod specification file /etc/kubernetes/manifests/etcd.yaml on the master node and either remove the --auto-tls parameter or set it to false:

--auto-tls=false
