OpenShift 4 includes multiple CAs providing independent chains of trust, which ensure that a platform CA will never accidentally sign a certificate that can be used for the wrong purpose, increasing the security posture of the cluster. OpenShift uses a separate CA for etcd. These internal self-signing CAs enable automation because the key is known to the cluster. The certificates generated by each CA are used to identify a particular OpenShift platform component to another OpenShift platform component.

修補方法: 操作指南或基礎設施修補檔

None required. Certificates for etcd are managed by the OpenShift cluster etcd operator.
