Depending on your current setup, this release may contain breaking changes. We go into these in more detail below and therefore ask you to read them carefully and check whether and to what extent they affect your setup.

Added

  • Deployment: Add controller.progressDeadlineSeconds.
  • Pod Disruption Budget: Add controller.unhealthyPodEvictionPolicy.

Changed

• Chart: Sync to upstream. (#768https://github.com/giantswarm/ingress-nginx-app/pull/768)
  • Controller: Update image to v1.12.0.
    NOTE: Please read the upstream changelog carefully, especially the entries marked with ⚠️. In addition, the following should be noted:
    • The --enable-annotation-validation CLI flag is already enabled by default in this app since v3.2.0.
    • The allow-cross-namespace-resources ConfigMap option getting deactivated affects you if you are currently referencing resources such as Secrets in Ingress resource annotations from namespaces other than the Ingress resource itself.
    • The annotations-risk-level ConfigMap option getting lowered to High affects you if you are currently using annotations with an annotation risk level of Critical. Especially snippet annotations belong to this annotation risk level. So even though you activated snippet annotations via ConfigMap option in the past, you now also need to increase the annotations-risk-level ConfigMap option back to Critical.
    • The strict-validate-path-type ConfigMap option is already enabled by default in this app since v3.2.0.
  • Values: Rename image to global.image.

Removed

• Chart: Sync to upstream. (#768https://github.com/giantswarm/ingress-nginx-app/pull/768)
  • Chart: Remove Pod Security Policies.
    NOTE: Pod Security Policies have already been removed from Kubernetes in v1.25. Therefore, this version is not compatible with Kubernetes v1.24 and below.
  • Values: Remove configmap.
    NOTE: The configmap value is deprecated since v3.0.0. Please use controller.config instead.
  • Deployment: Remove giantswarm.io/monitoring_basic_sli label.
  • Deployment: Remove OpenTelemetry init container.
    NOTE: OpenTelemetry is still supported, but since the module is built into the controller image since v1.10, we hereby remove the init container and image which were used to install it upon controller startup.
