Uninstall ingress

You must have an Ingress controller to satisfy an Ingress. Only creating an Ingress resource has no effect. You may need to deploy an Ingress controller such as ingress-nginx. You can choose from a number of Ingress controllers.

Ideally, all Ingress controllers should fit the reference specification. In reality, the various Ingress controllers operate slightly differently. As with all other Kubernetes resources, an Ingress needs apiVersion , kind , and metadata fields.

The name of an Ingress object must be a valid DNS subdomain name. For general information about working with config files, see deploying applications , configuring containers , managing resources. Ingress frequently uses annotations to configure some options depending on the Ingress controller, an example of which is the rewrite-target annotation. Different Ingress controllers support different annotations.

Review the documentation for your choice of Ingress controller to learn which annotations are supported. The Ingress spec has all the information needed to configure a load balancer or proxy server. Most importantly, it contains a list of rules matched against all incoming requests. A defaultBackend is often configured in an Ingress controller to service any requests that do not match a path in the spec. An Ingress with no rules sends all traffic to a single default backend.

The defaultBackend is conventionally a configuration option of the Ingress controller and is not specified in your Ingress resources. If none of the hosts or paths match the HTTP request in the Ingress objects, the traffic is routed to your default backend. A Resource backend is an ObjectRef to another Kubernetes resource within the same namespace as the Ingress object.

A Resource is a mutually exclusive setting with Service, and will fail validation if both are specified. A common usage for a Resource backend is to ingress data to an object storage backend with static assets. Each path in an Ingress is required to have a corresponding path type.

Paths that do not include an explicit pathType will fail validation. There are three supported path types:. ImplementationSpecific : With this path type, matching is up to the IngressClass. Implementations can treat this as a separate pathType or treat it identically to Prefix or Exact path types. Matching is case sensitive and done on a path element by element basis. A request is a match for path p if every p is an element-wise prefix of p of the request path.

In some cases, multiple paths within an Ingress will match a request. In those cases precedence will be given first to the longest matching path. If two paths are still equally matched, precedence will be given to paths with an exact path type over prefix path type. Delete the nginx-ingress namespace to uninstall the Ingress controller along with all the auxiliary resources that were created:. Capabilities labeled in preview status are fully supported.

Dos Protected Resource. To test the routes for the ingress controller, browse to the two applications. The first demo application is displayed in the web browser, as shown in the follow example:. The second demo application with the custom title is displayed:. This article used Helm to install the ingress components and sample apps. When you deploy a Helm chart, a number of Kubernetes resources are created. These resources includes pods, deployments, and services.

To clean up these resources, you can either delete the entire sample namespace, or the individual resources. To delete the entire sample namespace, use the kubectl delete command and specify your namespace name. All the resources in the namespace are deleted. Alternatively, a more granular approach is to delete the individual resources created. List the Helm releases with the helm list command. Look for charts named nginx-ingress and aks-helloworld , as shown in the following example output:.

Uninstall the releases with the helm uninstall command. Finally, you can delete the itself namespace. Use the kubectl delete command and specify your namespace name:. This article included some external components to AKS.
