Release Notes

cert-manager/cert-manager (quay.io/jetstack/charts/cert-manager)

v1.21.1

Compare Source

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

v1.21.1 fixes a controller panic for Certificates with spec.renewal.policy: Disabled, a regression in 1.21.0 which caused log spam and dropped Secret informer events, Issuers and ClusterIssuers getting stuck at Ready=False (InvalidSolver) when a referenced ACME DNS-01 solver Secret is created after the Issuer, and the commented Gateway API example in the Helm chart values. It also updates several dependencies to fix reported security vulnerabilities.

All users should upgrade.

  • Avoid controller panic if a Certificate sets spec.renewal.policy=Disabled (#​9038, @​sklirg)
  • Fix Issuer/ClusterIssuer stuck at Ready=False/InvalidSolver after a missing ACME DNS-01 solver Secret is created (#​9083, @​SebTardif)
