When using Helm, you can enable this annotation by setting. If a single instance of the Ingress-NGINX controller is the sole Ingress controller running in your cluster, you should add the annotation "/is-default-class" in your IngressClass, so any new Ingress objects will have this one as default IngressClass. I have only one ingress controller in my cluster. spec.ingressClassName behavior has precedence over the deprecated kubernetes.io/ingress.class annotation. For more information, refer to the IngressClass documentation. An IngressClass resource may be marked as default, which can be used to set a default value for this field. Implementations of this API should ignore Ingresses without a class specified. The controller may emit a warning if the field and annotation have different values. For backwards compatibility, when that annotation is set, it must be given precedence over this field. This replaces the deprecated `kubernetes.io/ingress.class` annotation. The associated IngressClass defines which controller will implement the resource. KIND: Ingress VERSION: /v1 FIELD: ingressClassName DESCRIPTION: IngressClassName is the name of the IngressClass cluster resource. IngressClassName is a field in the specs of an Ingress object.

#DOCKER DESKTOP NGINX INGRESS UPGRADE#
If you are already using the Ingress-NGINX controller and then upgrade to K8s version v1.22, there are several scenarios where your existing Ingress objects will not work how you expect. The reason is explained in the official blog on deprecated ingress API versions.
You would get a message about deprecation, but the Ingress resource would get created.įrom K8s version 1.22 onwards, you can only access the Ingress API via the stable, /v1 API. Until K8s version 1.21, it was possible to create an Ingress resource using deprecated versions of the Ingress API, such as: What has caused this change in behavior? ¶ Spec is the desired state of the IngressClass. Servers may infer this from the endpoint the client submits Kind is a string value representing the REST resource this object Value, and may reject unrecognized values. Servers should convert recognized schemas to the latest internal Resources without a class specified will be assigned this default class.ĪPIVersion defines the versioned schema of this representation of an Single IngressClass resource has this annotation set to true, new Ingress Used to indicate that an IngressClass should be considered default. The `/is-default-class` annotation can be IngressClass represents the class of the Ingress, referenced by the Ingress The ingressClassName field of an Ingress is the way to let the controller know about that. On clusters with more than one instance of the Ingress-NGINX controller, all instances of the controllers must be aware of which Ingress objects they serve. From version 1.0.0 of the Ingress-NGINX Controller, an IngressClass object is required.
#DOCKER DESKTOP NGINX INGRESS INSTALL#
Its important because until now, a default install of the Ingress-NGINX controller did not require any IngressClass object. What is an IngressClass and why is it important for users of Ingress-NGINX controller now ? ¶ Please read this official documentation on the IngressClass object Please read this official blog on deprecated Ingress API versions If you are using Ingress objects in your cluster (running Kubernetes older than v1.22), and you plan to upgrade to Kubernetess v1.22, this section is relevant to you. See Deployment for a whirlwind tour that will get you started. You can learn more about using Ingress in the official Kubernetes documentation. It is built around the Kubernetes Ingress resource, using a ConfigMap to store the controller configuration. This is the documentation for the Ingress NGINX Controller.
