Chapter 1. Deploying Developer Hub on AKS with the Operator

Procedure

1. Create an ImagePull Secret named rhdh-pull-secret using your Red Hat credentials to access images from the protected registry.redhat.io as shown in the following example:

   kubectl -n <your_namespace> create secret docker-registry rhdh-pull-secret \
       --docker-server=registry.redhat.io \
       --docker-username=<redhat_user_name> \
       --docker-password=<redhat_password> \
       --docker-email=<email>

2. Create an Ingress manifest file, named rhdh-ingress.yaml, specifying your Developer Hub service name as follows:

   apiVersion: networking.k8s.io/v1
   kind: Ingress
   metadata:
     name: rhdh-ingress
     namespace: my-rhdh-project
   spec:
     ingressClassName: webapprouting.kubernetes.azure.com
     rules:
       - http:
           paths:
             - path: /
               pathType: Prefix
               backend:
                 service:
                   name: backstage-<your-CR-name>
                   port:
                     name: http-backend

   Copy to Clipboard

3. To deploy the created Ingress, run the following command:

   kubectl -n <your_namespace> apply -f rhdh-ingress.yaml

   Copy to Clipboard

4. Create a my-rhdh-app-config config map containing the app-config.yaml Developer Hub configuration file by using the following example:

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: my-rhdh-app-config
   data:
     "app-config.yaml": |
       app:
         title: Red Hat Developer Hub
         baseUrl: https://<app_address>
       backend:
         auth:
           externalAccess:
               - type: legacy
                 options:
                   subject: legacy-default-config
                   secret: "${BACKEND_SECRET}"
         baseUrl: https://<app_address>
         cors:
           origin: https://<app_address>

   Copy to Clipboard

5. Create a <my_product_secrets> secret and add a key named BACKEND_SECRET with a Base64-encoded string value as shown in the following example:

   apiVersion: v1
   kind: Secret
   metadata:
     name: <my_product_secrets> 

   1

   
   stringData:
     BACKEND_SECRET: "xxx"

   Copy to Clipboard

   1

   <my_product_secrets> is your preferred Developer Hub secret name, where <my_product_secrets> specifies the identifier for your secret configuration within Developer Hub.

6. Create your Backstage custom resource (CR) manifest file named <your-rhdh-cr> and include the previously created rhdh-pull-secret as follows:

   apiVersion: rhdh.redhat.com/v1alpha3
   kind: Backstage
   metadata:
     name: <your-rhdh-cr>
   spec:
     application:
       imagePullSecrets:
         - rhdh-pull-secret
       appConfig:
         configMaps:
           - name: my-rhdh-app-config
       extraEnvs:
         secrets:
           - name: <my_product_secrets> 

   1

   Copy to Clipboard

   1

   <my_product_secrets> is your preferred Developer Hub secret name, where <my_product_secrets> specifies the identifier for your secret configuration within Developer Hub.

7. Apply the CR manifest to your namespace:

   kubectl -n my-rhdh-project apply -f rhdh.yaml

   Copy to Clipboard
8. Access the deployed Developer Hub using the URL: https://<app_address>, where <app_address> is the Ingress address obtained earlier (for example, https://108.141.70.228).

9. Optional: To delete the CR, run the following command:

   kubectl -n my-rhdh-project delete -f rhdh.yaml
