cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
The cert-manager 1.16 release includes: new Helm chart features, more Prometheus metrics, memory optimizations, and various improvements and bug fixes for the ACME issuer and Venafi Issuer.
Add SecretRef support for Venafi TPP issuer CA Bundle (#7036, @sankalp-at-gh)
Add renewBeforePercentage alternative to renewBefore (#6987, @cbroglie)
Add a metrics server to the cainjector (#7194, @wallrj)
Add a metrics server to the webhook (#7182, @wallrj)
Add client certificate auth method for Vault issuer (#4330, @joshmue)
Add process and go runtime metrics for controller (#6966, @mindw)
Added app.kubernetes.io/managed-by: cert-manager label to the cert-manager-webhook-ca Secret (#7154, @jrcichra)
Allow the user to specify a Pod template when using GatewayAPI HTTP01 solver, this mirrors the behavior when using the Ingress HTTP01 solver. (#7211, @ThatsMrTalbot)
Create token request RBAC for the cert-manager ServiceAccount by default (#7213, @Jasper-Ben)
Feature: Append cert-manager user-agent string to all AWS API requests, including IMDS and STS requests. (#7295, @wallrj)
Feature: Log AWS SDK warnings and API requests at cert-manager debug level to help debug AWS Route53 problems in the field. (#7292, @wallrj)
Feature: The Route53 DNS solver of the ACME Issuer will now use regional STS endpoints computed from the region that is supplied in the Issuer spec or in the AWS_REGION environment variable.
Feature: The Route53 DNS solver of the ACME Issuer now uses the "ambient" region (AWS_REGION or AWS_DEFAULT_REGION) if issuer.spec.acme.solvers.dns01.route53.region is empty; regardless of the flags --issuer-ambient-credentials and --cluster-issuer-ambient-credentials. (#7299, @wallrj)
Helm: adds JSON schema validation for the Helm values. (#7069, @inteon)
If the --controllers flag only specifies disabled controllers, the default controllers are now enabled implicitly.
Added disableAutoApproval and approveSignerNames Helm chart options. (#7049, @inteon)
Make it easier to configure cert-manager using Helm by defaulting config.apiVersion and config.kind within the Helm chart. (#7126, @ThatsMrTalbot)
Now passes down specified duration to Venafi client instead of using the CA default only. (#7104, @Guitarkalle)
Reduce the memory usage of cainjector, by only caching the metadata of Secret resources.
Reduce the load on the K8S API server when cainjector starts up, by only listing the metadata of Secret resources. (#7161, @wallrj)
The Route53 DNS01 solver of the ACME Issuer can now detect the AWS region from the AWS_REGION and AWS_DEFAULT_REGION environment variables, which is set by the IAM for Service Accounts (IRSA) webhook and by the Pod Identity webhook.
The issuer.spec.acme.solvers.dns01.route53.region field is now optional.
The API documentation of the region field has been updated to explain when and how the region value is used. (#7287, @wallrj)
Venafi TPP issuer can now be used with a username & password combination with OAuth. Fixes #4653.
Breaking: cert-manager will no longer use the API Key authentication method which was deprecated in 20.2 and since removed in 24.1 of TPP. (#7084, @hawksight)
You can now configure the pod security context of HTTP-01 solver pods. (#5373, @aidy)
Helm: New value webhook.extraEnv, allows you to set custom environment variables in the webhook Pod.
Helm: New value cainjector.extraEnv, allows you to set custom environment variables in the cainjector Pod.
Helm: New value startupapicheck.extraEnv, allows you to set custom environment variables in the startupapicheck Pod. (#7319, @wallrj)
