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. Image size must not exceed 1 MB due to constraints on the ConfigMap object size.

Procedure

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

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

    $ 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.

  3. 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:

    $ oc get clusteroperator console -o yaml

    To check the console Operator configuration, run:

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

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

  1. Edit the cluster Ingress configuration:

    $ oc edit ingress.config.openshift.io cluster
  2. 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.
  3. 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

  1. Edit the cluster Ingress configuration:

    $ oc edit ingress.config.openshift.io cluster
  2. 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.
  3. 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

  1. Run the following commands to create templates you can modify:

    $ oc adm create-login-template > login.html
    $ oc adm create-provider-selection-template > providers.html
    $ oc adm create-error-template > errors.html
  2. Create the secrets:

    $ oc create secret generic login-template --from-file=login.html -n openshift-config
    $ oc create secret generic providers-template --from-file=providers.html -n openshift-config
    $ oc create secret generic error-template --from-file=errors.html -n openshift-config
  3. Run:

    $ oc edit oauths cluster
  4. 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.

6.6. Creating custom notification banners

    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

    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.

  3. Click Save.

6.9. Customizing user perspectives

The OpenShift Container Platform web console provides two perspectives by default, Administrator and Developer. You might have more perspectives available depending on installed console plugins. As a cluster administrator, you can show or hide a perspective for all users or for a specific user role. Customizing perspectives ensures that users can view only the perspectives that are applicable to their role and tasks. For example, you can hide the Administrator perspective from unprivileged users so that they cannot manage cluster resources, users, and projects. Similarly, you can show the Developer perspective to users with the developer role so that they can create, deploy, and monitor applications.

You can also customize the perspective visibility for users based on role-based access control (RBAC). For example, if you customize a perspective for monitoring purposes, which requires specific permissions, you can define that the perspective is visible only to users with required permissions.

Each perspective includes the following mandatory parameters, which you can edit in the YAML view:

  • id: Defines the ID of the perspective to show or hide
  • visibility: Defines the state of the perspective along with access review checks, if needed
  • state: Defines whether the perspective is enabled, disabled, or needs an access review check
Note

By default, all perspectives are enabled. When you customize the user perspective, your changes are applicable to the entire cluster.

6.9.1. Customizing a perspective using YAML view

Prerequisites

  • You must have administrator privileges.

Procedure

  1. In the Administrator perspective, navigate to Administration Cluster Settings.
  2. Select the Configuration tab and click the Console (operator.openshift.io) resource.
  3. Click the YAML tab and make your customization:

    1. To enable or disable a perspective, insert the snippet for Add user perspectives and edit the YAML code as needed:

      apiVersion: operator.openshift.io/v1
      kind: Console
      metadata:
        name: cluster
      spec:
        customization:
          perspectives:
            - id: admin
              visibility:
                state: Enabled
            - id: dev
              visibility:
                state: Enabled
    2. To hide a perspective based on RBAC permissions, insert the snippet for Hide user perspectives and edit the YAML code as needed:

      apiVersion: operator.openshift.io/v1
      kind: Console
      metadata:
        name: cluster
      spec:
        customization:
          perspectives:
            - id: admin
              requiresAccessReview:
                - group: rbac.authorization.k8s.io
                  resource: clusterroles
                  verb: list
            - id: dev
              state: Enabled
    3. To customize a perspective based on your needs, create your own YAML snippet:

      apiVersion: operator.openshift.io/v1
      kind: Console
      metadata:
        name: cluster
      spec:
        customization:
          perspectives:
            - id: admin
              visibility:
                state: AccessReview
                accessReview:
                  missing:
                    - resource: deployment
                      verb: list
                  required:
                    - resource: namespaces
                      verb: list

      Note

      When you customize the user perspective, your changes are automatically saved and take effect after a browser refresh.

6.10. Developer catalog and sub-catalog customization

As a cluster administrator, you have the ability to organize and manage the Developer catalog or its sub-catalogs. You can enable or disable the sub-catalog types or disable the entire developer catalog.

The developerCatalog.types object includes the following parameters that you must define in a snippet to use them in the YAML view:

  • state: Defines if a list of developer catalog types should be enabled or disabled.
  • enabled: Defines a list of developer catalog types (sub-catalogs) that are visible to users.
  • disabled: Defines a list of developer catalog types (sub-catalogs) that are not visible to users.

You can enable or disable the following developer catalog types (sub-catalogs) using the YAML view or the form view.

  • Builder Images
  • Templates
  • Devfiles
  • Samples
  • Helm Charts
  • Event Sources
  • Event Sinks
  • Operator Backed

6.10.1. Customizing a developer catalog or its sub-catalogs using the YAML view

You can customize a developer catalog by editing the YAML content in the YAML view.

Prerequisites

  • An OpenShift web console session with cluster administrator privileges.

    metadata:
      name: cluster
    ...
    spec:
      customization:
        developerCatalog:
          categories:
          types:
            state: Disabled
            disabled:
              - BuilderImage
              - Devfile
              - HelmChart
    ...
  4. Click Save.
Note

By default, the developer catalog types are enabled in the Administrator view of the Web Console.
