Customizing the web console in OKD

You can customize the OKD 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.

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

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

    1. $ oc create configmap console-custom-logo --from-file /path/to/console-custom-logo.png -n openshift-config
    1. apiVersion: v1
    2. kind: ConfigMap
    3. metadata:
    4.   name: console-custom-logo
    5.   namespace: openshift-config
    6. data:
    7.   console-custom-logo.png: <base64-encoded_logo> ... (1)
    1Provide a valid base64 encoded logo.

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

    1. $ oc edit consoles.operator.openshift.io cluster
    1. apiVersion: operator.openshift.io/v1
    2. kind: Console
    3. metadata:
    4.   name: cluster
    5. spec:
    6.   customization:
    7.     customLogoFile:
    8.       key: console-custom-logo.png
    9.       name: console-custom-logo
    10.     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:

    1. $ oc get clusteroperator console -o yaml

    To check the console Operator configuration, run:

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

Prerequisites

  • You must have administrator privileges.

Procedure

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

  2. Select Instances tab

  3. Click Create Console Link and edit the file:

    1. apiVersion: console.openshift.io/v1
    2. kind: ConsoleLink
    3. metadata:
    4.   name: example
    5. spec:
    6.   href: 'https://www.example.com'
    7.   location: HelpMenu (1)
    8.   text: Link 1
    1Valid location settings are HelpMenu, UserMenu, ApplicationMenu, and NamespaceDashboard.

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

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

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

    1. apiVersion: console.openshift.io/v1
    2. kind: ConsoleLink
    3. metadata:
    4.   name: namespaced-dashboard-for-some-namespaces
    5. spec:
    6.   href: 'https://www.example.com'
    7.   location: NamespaceDashboard
    8.   # This text will appear in a box called "Launcher" under "namespace" or "project" in the web console
    9.   text: Custom Link Text
    10.   namespaceDashboard:
    11.     namespaces:
    12.     # for these specific namespaces
    13.     - my-namespace
    14.     - your-namespace
    15.     - other-namespace

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

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

Customizing the web console URL

You can update the web console URL, consoleURL, to a custom value.

Procedure

  1. Modify the cluster instance created by default during installation in the consoles.operator.openshift.io custom resource:

    1. $ oc patch consoles.operator.openshift.io cluster --patch '{"spec":{"route":{"hostname":"console.example.com"}}}' --type=merge
    1. apiVersion: operator.openshift.io/v1
    2. kind: Console
    3. metadata:
    4.   name: cluster
    5. spec:
    6.   route:
    7.     hostname: 'console.example.com'

  2. If you specify a custom certificate, you must create a secret in the openshift-config namespace that has the key and certificate. For example:

    1. $ oc create secret tls console-tls --key=key.pem --cert=cert.pem -n openshift-config
    1. apiVersion: v1
    2. kind: Secret
    3. metadata:
    4.   name: console-tls
    5.   namespace: openshift-config
    6. type: kubernetes.io/tls
    7. data:
    8.   tls.crt: >-
    9.         <base64-encoded_cert> ... (1)
    10.   tls.key: >-
    11.         <base64-encoded_key> ... (2)
    1Provide a valid TLS certificate.
    2Provide a valid TLS key.

    Then, edit the web console’s Operator configuration:

    1. $ oc edit consoles.operator.openshift.io cluster

    Add the following stanza to the configuration resource:

    1. spec:
    2.   route:
    3.     hostname: console.example.com
    4.     secret:
    5.       name: console-tls

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.

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:

    1. $ oc adm create-login-template > login.html
    1. $ oc adm create-provider-selection-template > providers.html
    1. $ oc adm create-error-template > errors.html

  2. Create the secrets:

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

  3. Run:

    1. $ oc edit oauths cluster

  4. Update the specification:

    1. spec:
    2.   templates:
    3.     error:
    4.         name: error-template
    5.     login:
    6.         name: login-template
    7.     providerSelection:
    8.         name: providers-template

    Run oc explain oauths.spec.templates to understand the options.

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.
