Chapter 4. Customizing the web console in OpenShift Container Platform

Procedure

1. Import your logo file into a ConfigMap in the openshift-config namespace:

   $ oc create configmap console-custom-logo --from-file /path/to/console-custom-logo.png -n openshift-config

2. Edit the web console’s Operator configuration to include customLogoFile and customProductName:

   $ oc edit console.operator.openshift.io cluster

   apiVersion: operator.openshift.io/v1
   kind: Console
   metadata:
     name: cluster
   spec:
     customization:
       customLogoFile:
         key: console-custom-logo.png
         name: console-custom-logo
       customProductName: My Console

   Once the Operator configuration is updated, it will sync the custom logo ConfigMap into the console namespace, mount it to the console pod, and redeploy.

3. Check for success. If there are any issues, the console cluster operator will report Degraded, and the console Operator configuration will also report CustomLogoDegraded, but with reasons like KeyOrFilenameInvalid or NoImageProvided.

   To check the clusteroperator, run:

   $ oc get clusteroperator console -o yaml

   To check the console Operator configuration, run:

   $ oc get console.operator.openshift.io -o yaml

Procedure

1. From Administration Custom Resource Definitions, click on ConsoleLink.

2. Click YAML and edit the file:

   apiVersion: console.openshift.io/v1
   kind: ConsoleLink
   metadata:
     name: example
   spec:
     href: 'https://www.example.com'
     location: HelpMenu 1
     text: Link 1

   1

   Valid location settings are HelpMenu, UserMenu, ApplicationMenu, and NamespaceDashboard.

   To make the custom link appear in all namespaces, follow this example:

   apiVersion: console.openshift.io/v1
   kind: ConsoleLink
   metadata:
     name: namespaced-dashboard-link-for-all-namespaces
   spec:
     href: 'https://www.example.com'
     location: NamespaceDashboard
     text: This appears in all namespaces

   To make the custom link appear in only some namespaces, follow this example:

   apiVersion: console.openshift.io/v1
   kind: ConsoleLink
   metadata:
     name: namespaced-dashboard-for-some-namespaces
   spec:
     href: 'https://www.example.com'
     location: NamespaceDashboard
     # This text will appear in a box called "Launcher" under "namespace" or "project" in the web console
     text: Custom Link Text
     namespaceDashboard:
       namespaces:
       # for these specific namespaces
       - my-namespace
       - your-namespace
       - other-namespace

   To make the custom link appear in the application menu, follow this example:

   apiVersion: console.openshift.io/v1
   kind: ConsoleLink
   metadata:
     name: application-menu-link-1
   spec:
     href: 'https://www.example.com'
     location: ApplicationMenu
     text: Link 1
     applicationMenu:
       section: My New Section
       # image that is 24x24 in size
       imageURL: https://via.placeholder.com/24
