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 Copia collegamentoCollegamento copiato negli appunti!
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
of60px
. Image size must not exceed 1 MB due to constraints on theConfigMap
object size.
Procedure
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
$ oc create configmap console-custom-logo --from-file /path/to/console-custom-logo.png -n openshift-config

:oc edit consoles.operator.openshift.io cluster

Check for success. If there are any issues, the console cluster Operator will report a

status, and the console Operator configuration will also report aCustomLogoDegraded
status, but with reasons likeKeyOrFilenameInvalid

6.3. Customizing console routes Copia collegamentoCollegamento copiato negli appunti!
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 Copia collegamentoCollegamento copiato negli appunti!
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.TipYou can create a TLS secret by using the
oc create secret tls
command.
Procedure
Edit the cluster
Ingress
configuration:oc edit ingress.config.openshift.io cluster
$ oc edit ingress.config.openshift.io cluster
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Set the custom hostname and optionally the serving certificate and key:
Copy to Clipboard Copied! Toggle word wrap Toggle overflow - Save the file to apply the changes.
Add a DNS record for the custom console route that points to the application ingress load balancer.
6.3.2. Customizing the download route Copia collegamentoCollegamento copiato negli appunti!
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.TipYou can create a TLS secret by using the

6.4. Customizing the login page Copia collegamentoCollegamento copiato negli appunti!
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
Run the following commands to create templates you can modify:
oc adm create-login-template > login.html
$ oc adm create-login-template > login.html

6.9. Customizing user perspectives Copia collegamentoCollegamento copiato negli appunti!
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
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 Copia collegamentoCollegamento copiato negli appunti!

Customize on the right side of the page. In the General settings, customize the perspective by selecting one of the following options from the dropdown list:
- Enabled: Enables the perspective for all users
- Only visible for privileged users: Enables the perspective for users who can list all namespaces
- Only visible for unprivileged users: Enables the perspective for users who cannot list all namespaces
Disabled: Disables the perspective for all users
A notification opens to confirm that your changes are saved.
NoteWhen 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 Copia collegamentoCollegamento copiato negli appunti!
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.
