ClusterIssuer


Ícono del recurso​

Descripción general del recurso​

ClusterIssuer is a cluster-scoped Kubernetes resource used by cert-manager to receive Certificate Signing Requests (CSRs) and obtain signed certificates from a Certificate Authority (CA). Unlike Issuer, it is not bound to a specific namespace and can be commonly referenced by Certificate resources across the entire cluster. It uses ACME-based Certificate Authorities (for example, Let’s Encrypt) and verifies domain ownership through HTTP-01 or DNS-01 challenges.
