Procedure

1. Run:

   $ oc status

   This command provides a high-level overview of the current project, with its components and their relationships.

Procedure

1. Navigate to Home Projects.
2. Locate the project that you want to delete from the list of projects.
3. On the far right side of the project listing, select Delete Project from the Options menu .
4. When the Delete Project pane opens, enter the name of the project that you want to delete in the field.
5. Click Delete.

Procedure

1. Run:

   $ oc delete project <project_name>

Procedure

1. Log in as a user with cluster-admin privileges.

2. Generate the default project template:

   $ oc adm create-bootstrap-project-template -o yaml > template.yaml

3. Use a text editor to modify the generated template.yaml file by adding objects or modifying existing objects.

4. The project template must be created in the openshift-config namespace. Load your modified template:

   $ oc create -f template.yaml -n openshift-config

5. Edit the project configuration resource using the web console or CLI.

   • Using the web console:

     1. Navigate to the Administration Cluster Settings page.
     2. Click Global Configuration to view all configuration resources.
     3. Find the entry for Project and click Edit YAML.

   • Using the CLI:

     1. Edit the project.config.openshift.io/cluster resource:

        $ oc edit project.config.openshift.io/cluster

6. Update the spec section to include the projectRequestTemplate and name parameters, and set the name of your uploaded project template. The default name is project-request.

   Project configuration resource with custom project template

   apiVersion: config.openshift.io/v1
   kind: Project
   metadata:
     ...
   spec:
     projectRequestTemplate:
       name: <template_name>

7. After you save your changes, create a new project to verify that your changes were successfully applied.

Procedure

1. Log in as a user with cluster-admin privileges.

2. View the self-provisioners cluster role binding usage by running the following command:

   $ oc describe clusterrolebinding.rbac self-provisioners

   Example output

   Name:		self-provisioners
   Labels:		<none>
   Annotations:	rbac.authorization.kubernetes.io/autoupdate=true
   Role:
     Kind:	ClusterRole
     Name:	self-provisioner
   Subjects:
     Kind	Name				Namespace
     ----	----				---------
     Group	system:authenticated:oauth

   Review the subjects in the self-provisioners section.

3. Remove the self-provisioner cluster role from the group system:authenticated:oauth.

   • If the self-provisioners cluster role binding binds only the self-provisioner role to the system:authenticated:oauth group, run the following command:

     $ oc patch clusterrolebinding.rbac self-provisioners -p '{"subjects": null}'

   • If the self-provisioners cluster role binding binds the self-provisioner role to more users, groups, or service accounts than the system:authenticated:oauth group, run the following command:

     $ oc adm policy \
         remove-cluster-role-from-group self-provisioner \
         system:authenticated:oauth

4. Edit the self-provisioners cluster role binding to prevent automatic updates to the role. Automatic updates reset the cluster roles to the default state.

   • To update the role binding using the CLI:

     1. Run the following command:

        $ oc edit clusterrolebinding.rbac self-provisioners

     2. In the displayed role binding, set the rbac.authorization.kubernetes.io/autoupdate parameter value to false, as shown in the following example:

        apiVersion: authorization.openshift.io/v1
        kind: ClusterRoleBinding
        metadata:
          annotations:
            rbac.authorization.kubernetes.io/autoupdate: "false"
          ...

   • To update the role binding by using a single command:

     $ oc patch clusterrolebinding.rbac self-provisioners -p '{ "metadata": { "annotations": { "rbac.authorization.kubernetes.io/autoupdate": "false" } } }'

5. Log in as an authenticated user and verify that it can no longer self-provision a project:

   $ oc new-project test

   Example output

   Error from server (Forbidden): You may not request a new project via this API.

   Consider customizing this project request message to provide more helpful instructions specific to your organization.

Procedure

1. Edit the project configuration resource using the web console or CLI.

   • Using the web console:

     1. Navigate to the Administration Cluster Settings page.
     2. Click Global Configuration to view all configuration resources.
     3. Find the entry for Project and click Edit YAML.

   • Using the CLI:

     1. Log in as a user with cluster-admin privileges.

     2. Edit the project.config.openshift.io/cluster resource:

        $ oc edit project.config.openshift.io/cluster

2. Update the spec section to include the projectRequestMessage parameter and set the value to your custom message:

   Project configuration resource with custom project request message

   apiVersion: config.openshift.io/v1
   kind: Project
   metadata:
     ...
   spec:
     projectRequestMessage: <message_string>

   For example:

   apiVersion: config.openshift.io/v1
   kind: Project
   metadata:
     ...
   spec:
     projectRequestMessage: To request a project, contact your system administrator at projectname@example.com.

3. After you save your changes, attempt to create a new project as a developer or service account that is unable to self-provision projects to verify that your changes were successfully applied.
