Managing TLS certificates in a distributed Ceph cluster can be complex and error-prone, with expired or misconfigured certificates often leading to service disruptions and operational overhead.

We’ll briefly explore how certmgr handles certificate generation, distribution, and renewal, helping operators maintain secure communication with minimal manual intervention.
