1.2.30 Ensure that the --etcd-cafile argument is set as appropriate

Information

etcd should be configured to make use of TLS encryption for client connections.

etcd is a highly-available key value store used by Kubernetes deployments for persistent storage of all of its REST API objects. These objects are sensitive in nature and should be protected by client authentication. This requires the API server to identify itself to the etcd server using a SSL Certificate Authority file.

Solution

None.

Impact:

TLS and client certificate authentication must be configured for etcd
