Chapter 6. Customizing the web console in OpenShift Container Platform You can customize the OpenShift Container Platform web console to set a custom logo, product name, links, notifications, and command line downloads. This is especially helpful if you need to tailor the web console to meet specific corporate or government requirements. 6.1. Adding a custom logo and product name You can create custom branding by adding a custom logo or custom product name. You can set both or one without the other, as these settings are independent of each other. Prerequisites You must have administrator privileges. Create a file of the logo that you want to use. The logo can be a file in any common image format, including GIF, JPG, PNG, or SVG, and is constrained to a max-height of 60px . Procedure Import your logo file into a config map in the openshift-config namespace: USD oc create configmap console-custom-logo --from-file /path/to/console-custom-logo.png -n openshift-config Tip You can alternatively apply the following YAML to create the config map: apiVersion: v1 kind: ConfigMap metadata: name: console-custom-logo namespace: openshift-config binaryData: console-custom-logo.png: <base64-encoded_logo> ... 1 1 Provide a valid base64-encoded logo. Edit the web console's Operator configuration to include customLogoFile and customProductName : USD oc edit consoles.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 config map into the console namespace, mount it to the console pod, and redeploy. Check for success. If there are any issues, the console cluster Operator will report a Degraded status, and the console Operator configuration will also report a CustomLogoDegraded status, but with reasons like KeyOrFilenameInvalid or NoImageProvided . To check the clusteroperator , run: USD oc get clusteroperator console -o yaml To check the console Operator configuration, run: USD oc get consoles.operator.openshift.io -o yaml 6.2. Creating custom links in the web console Prerequisites You must have administrator privileges. Procedure From Administration Custom Resource Definitions , click on ConsoleLink . Select Instances tab Click Create Console Link 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 Click Save to apply your changes. 6.3. Customizing console routes For console and downloads routes, custom routes functionality uses the ingress config route configuration API. If the console custom route is set up in both the ingress config and console-operator config, then the new ingress config custom route configuration takes precedent. The route configuration with the console-operator config is deprecated. 6.3.1. Customizing the console route You can customize the console route by setting the custom hostname and TLS certificate in the spec.componentRoutes field of the cluster Ingress configuration. Prerequisites You have logged in to the cluster as a user with administrative privileges. You have created a secret in the openshift-config namespace containing the TLS certificate and key. This is required if the domain for the custom hostname suffix does not match the cluster domain suffix. The secret is optional if the suffix matches. Tip You can create a TLS secret by using the oc create secret tls command. Procedure Edit the cluster Ingress configuration: USD oc edit ingress.config.openshift.io cluster Set the custom hostname and optionally the serving certificate and key: apiVersion: config.openshift.io/v1 kind: Ingress metadata: name: cluster spec: componentRoutes: - name: console namespace: openshift-console hostname: <custom_hostname> 1 servingCertKeyPairSecret: name: <secret_name> 2 1 The custom hostname. 2 Reference to a secret in the openshift-config namespace that contains a TLS certificate ( tls.crt ) and key ( tls.key ). This is required if the domain for the custom hostname suffix does not match the cluster domain suffix. The secret is optional if the suffix matches. Save the file to apply the changes. 6.3.2. Customizing the download route You can customize the download route by setting the custom hostname and TLS certificate in the spec.componentRoutes field of the cluster Ingress configuration. Prerequisites You have logged in to the cluster as a user with administrative privileges. You have created a secret in the openshift-config namespace containing the TLS certificate and key. This is required if the domain for the custom hostname suffix does not match the cluster domain suffix. The secret is optional if the suffix matches. Tip You can create a TLS secret by using the oc create secret tls command. Procedure Edit the cluster Ingress configuration: USD oc edit ingress.config.openshift.io cluster Set the custom hostname and optionally the serving certificate and key: apiVersion: config.openshift.io/v1 kind: Ingress metadata: name: cluster spec: componentRoutes: - name: downloads namespace: openshift-console hostname: <custom_hostname> 1 servingCertKeyPairSecret: name: <secret_name> 2 1 The custom hostname. 2 Reference to a secret in the openshift-config namespace that contains a TLS certificate ( tls.crt ) and key ( tls.key ). This is required if the domain for the custom hostname suffix does not match the cluster domain suffix. The secret is optional if the suffix matches. Save the file to apply the changes. 6.4. Customizing the login page Create Terms of Service information with custom login pages. Custom login pages can also be helpful if you use a third-party login provider, such as GitHub or Google, to show users a branded page that they trust and expect before being redirected to the authentication provider. You can also render custom error pages during the authentication process. Note Customizing the error template is limited to identity providers (IDPs) that use redirects, such as request header and OIDC-based IDPs. It does not have an effect on IDPs that use direct password authentication, such as LDAP and htpasswd. Prerequisites You must have administrator privileges. Procedure Run the following commands to create templates you can modify: USD oc adm create-login-template > login.html USD oc adm create-provider-selection-template > providers.html USD oc adm create-error-template > errors.html Create the secrets: USD oc create secret generic login-template --from-file=login.html -n openshift-config USD oc create secret generic providers-template --from-file=providers.html -n openshift-config USD oc create secret generic error-template --from-file=errors.html -n openshift-config Run: USD oc edit oauths cluster Update the specification: apiVersion: config.openshift.io/v1 kind: OAuth metadata: name: cluster # ... spec: templates: error: name: error-template login: name: login-template providerSelection: name: providers-template Run oc explain oauths.spec.templates to understand the options. 6.5. Defining a template for an external log link If you are connected to a service that helps you browse your logs, but you need to generate URLs in a particular way, then you can define a template for your link. Prerequisites You must have administrator privileges. Procedure From Administration Custom Resource Definitions , click on ConsoleExternalLogLink . Select Instances tab Click Create Console External Log Link and edit the file: apiVersion: console.openshift.io/v1 kind: ConsoleExternalLogLink metadata: name: example spec: hrefTemplate: >- https://example.com/logs?resourceName=USD{resourceName}&containerName=USD{containerName}&resourceNamespace=USD{resourceNamespace}&podLabels=USD{podLabels} text: Example Logs 6.6. Creating custom notification banners Prerequisites You must have administrator privileges. Procedure From Administration Custom Resource Definitions , click on ConsoleNotification . Select Instances tab Click Create Console Notification and edit the file: apiVersion: console.openshift.io/v1 kind: ConsoleNotification metadata: name: example spec: text: This is an example notification message with an optional link. location: BannerTop 1 link: href: 'https://www.example.com' text: Optional link text color: '#fff' backgroundColor: '#0088ce' 1 Valid location settings are BannerTop , BannerBottom , and BannerTopBottom . Click Create to apply your changes. 6.7. Customizing CLI downloads You can configure links for downloading the CLI with custom link text and URLs, which can point directly to file packages or to an external page that provides the packages. Prerequisites You must have administrator privileges. Procedure Navigate to Administration Custom Resource Definitions . Select ConsoleCLIDownload from the list of Custom Resource Definitions (CRDs). Click the YAML tab, and then make your edits: apiVersion: console.openshift.io/v1 kind: ConsoleCLIDownload metadata: name: example-cli-download-links spec: description: | This is an example of download links displayName: example links: - href: 'https://www.example.com/public/example.tar' text: example for linux - href: 'https://www.example.com/public/example.mac.zip' text: example for mac - href: 'https://www.example.com/public/example.win.zip' text: example for windows Click the Save button. 6.8. Adding YAML examples to Kubernetes resources You can dynamically add YAML examples to any Kubernetes resources at any time. Prerequisites You must have cluster administrator privileges. Procedure From Administration Custom Resource Definitions , click on ConsoleYAMLSample . Click YAML and edit the file: apiVersion: console.openshift.io/v1 kind: ConsoleYAMLSample metadata: name: example spec: targetResource: apiVersion: batch/v1 kind: Job title: Example Job description: An example Job YAML sample yaml: | apiVersion: batch/v1 kind: Job metadata: name: countdown spec: template: metadata: name: countdown spec: containers: - name: counter image: centos:7 command: - "bin/bash" - "-c" - "for i in 9 8 7 6 5 4 3 2 1 ; do echo USDi ; done" restartPolicy: Never Use spec.snippet to indicate that the YAML sample is not the full YAML resource definition, but a fragment that can be inserted into the existing YAML document at the user's cursor.
