cert-manager trust-manager manages trust bundles in Kubernetes and OpenShift clusters
trust-manager is a Kubernetes operator from the cert-manager project that distributes trust bundles across clusters. It assembles X.509 CA certificates from multiple sources and syncs them into ConfigMaps or Secrets in every namespace where your workloads need them.
The trust-manager image is used with the companion image trust-mananger-package, which provides the default CA certificate bundle used by trust-manager. When installed via Helm, trust-manager has a dependency on cert-manager for provisioning an application certificate unless you explicitly opt to use a Helm-generated certificate instead.
