helm/cert-manager/cert-manager 1.15.0

v1.15.0

on Artifact Hub

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

cert-manager 1.15 promotes several features to beta, including GatewayAPI support (ExperimentalGatewayAPISupport), the ability to provide a subject in the Certificate that will be used literally in the CertificateSigningRequest (LiteralCertificateSubject) and the outputting of additional certificate formats (AdditionalCertificateOutputFormats).
