Release Notes

cert-manager/cert-manager (cert-manager/cert-manager)

v1.18.2

Compare Source

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

We fixed a bug in the CSR's name constraints construction (only applies if you have enabled the NameConstraints feature gate).
We dropped the new global.rbac.disableHTTPChallengesRole Helm option due to a bug we found, this feature will be released in v1.19 instead.

Changes since v1.18.1:

Bug or Regression

• BUGFIX: permitted URI domains were incorrectly used to set the excluded URI domains in the CSR's name constraints (#​7833, @​cert-manager-bot)
• Reverted adding the global.rbac.disableHTTPChallengesRole Helm option. (#​7837, @​cert-manager-bot)

v1.18.1

Compare Source

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

We have added a new feature gate ACMEHTTP01IngressPathTypeExact, to allow ingress-nginx users to turn off the new default Ingress PathType: Exact behavior, in ACME HTTP01 Ingress challenge solvers.
This change fixes the following issue: #​7791

We have increased the ACME challenge authorization timeout to two minutes, which we hope will fix a timeout error (error waiting for authorization), which has been reported by multiple users, since the release of cert-manager v1.16.0.
This change should fix the following issues: #​7337, #​7444, and #​7685.

ℹ️ Be sure to review all new features and changes below, and read the full release notes carefully before upgrading.

v1.18.0

Compare Source

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

cert-manager 1.18 introduces several new features and breaking changes. Highlights include support for ACME certificate profiles, a new default for Certificate.Spec.PrivateKey.RotationPolicy now set to Always (breaking change), and the default Certificate.Spec.RevisionHistoryLimit now set to 1 (potentially breaking).
