Expose Cluster Services Using Ingress

​

Pre-Operation Confirmation

• A Service has been created to access backend Pods. For details, see Create and Manage a Service.
• The cluster has an installed component for processing Ingress routing.

​

Create Ingress

1. Log in to the GPU Cloud console and go to the Clusters page.
2. Click the name of the target cluster to access the cluster workspace.
3. In the left navigation pane, click Network.
4. Switch to the Ingress tab and click Create.
5. Configure Ingress.

   Parameter	Description
   Name	Set the Ingress name. We recommend using a name that reflects the purpose of the service or entry point.
   Namespace	Select the namespace to which the Ingress belongs. An Ingress must reference Services in the same namespace.
   Labels	Optional. Add labels to identify or filter the Ingress.
   Spec (YAML)	Enter the Kubernetes spec for the Ingress. Include only the content under spec; apiVersion, kind, and metadata are not required.

   • Ingress Spec Example
   • Complete Ingress YAML Reference

   Replace the domain name, Service name, and port with the actual values for your service.

   rules:
     - host: example.com
       http:
         paths:
           - path: /
             pathType: Prefix
             backend:
               service:
                 name: nginx-service
                 port:
                   number: 80
   

   When preparing a complete Ingress manifest using Kubernetes YAML, you can refer to the following structure.

   apiVersion: networking.k8s.io/v1
   kind: Ingress
   metadata:
     name: nginx-ingress
     namespace: default
   spec:
     rules:
       - host: example.com
         http:
           paths:
             - path: /
               pathType: Prefix
               backend:
                 service:
                   name: nginx-service
                   port:
                     number: 80
   
   The service.name and port in the example must match those of the existing Service, and the Ingress and target Service must be in the same namespace.
6. Submit the creation. Return to the Ingress tab to verify that the Ingress has been created, and check whether the domain name, path, and target Service meet expectations.

​

Modify or Remove Access Entry Points

1. On the Ingress tab, filter by namespace or use the search box to locate the target Ingress.
2. Perform actions as needed:
   • Modify a route: Click Edit, make the changes, and submit them.
   • Delete an entry: Click Delete, and verify the resource information in the confirmation dialog.
