 Spinnaker will only give you access to Docker images that have been whitelisted, if you're using a private registry or a private repository you also need to provide credentials.  Update the following values of the chart to do so:
 
-    ```yaml
-    dockerRegistries:
-    - name: dockerhub
-      address: index.docker.io
-      repositories:
-        - library/alpine
-        - library/ubuntu
-        - library/centos
-        - library/nginx
-    # - name: gcr
-    #   address: https://gcr.io
-    #   username: _json_key
-    #   password: '<INSERT YOUR SERVICE ACCOUNT JSON HERE>'
-    #   email: 1234@5678.com
-    ```

+dockerRegistries:
+- name: dockerhub

 You can provide passwords as a Helm value, or you can use a pre-created secret containing your registry passwords.  The secret should have an item per Registry in the format: `<registry name>: <password>`. In which case you'll specify the secret to use in `dockerRegistryAccountSecret` like so:
 
-    ```yaml
-    dockerRegistryAccountSecret: myregistry-secrets
-    ```
+```yaml
+dockerRegistryAccountSecret: myregistry-secrets
