Jenkins Role-base authorization Strategy:   Using the Plugin for RBAC.

The Role-Based Authorization Strategy plugin in Jenkins is used to implement Role-Based Access Control (RBAC), allowing you to assign granular permissions to users and groups. This plugin is essential for securing Jenkins in multi-user environments.

Steps:

1. Install the Plugin

1. Go to Jenkins Dashboard → Manage Jenkins → Manage Plugins.
2. Search for Role-Based Authorization Strategy.
3. Install the plugin and restart Jenkins.

2. Enable the Role-Based Authorization Strategy

1. Navigate to Manage Jenkins → Configure Global Security.
2. Under Authorization, select Role-Based Strategy.
3. Click Save.

3. Configure Roles and Permissions

Step 1: Access the Role-Based Strategy Settings

• Go to Manage Jenkins → Manage and Assign Roles.

Step 2: Create Roles

There are two main types of roles:

1. Global Roles (Affect the entire Jenkins instance)
2. Project Roles (Restrict access to specific jobs or projects)

Creating a Global Role

• Click Manage Roles.
• Under Global roles, add a role name (e.g., admin, developer, viewer).
• Assign necessary permissions by checking the corresponding boxes.
• Click Save.

Creating a Project Role

• Under Project roles, add a role name.
• Use a pattern (e.g., project-.*) to apply the role to jobs with matching names.
• Assign necessary permissions and click Save.

4. Assign Roles to Users or Groups

1. Navigate to Manage and Assign Roles → Assign Roles.
2. Under Users/Groups, enter the username (must match the user in Jenkins).
3. Assign roles by selecting checkboxes for global or project-specific roles.
4. Click Save.

5. Verify Role-Based Access

• Log in with a different user account to test permissions.
• Ensure users can access only the jobs and settings defined by their roles.

Additional Features

• LDAP or Active Directory Integration: You can assign roles based on external authentication systems.
• Folder-based Authorization: If using Folders Plugin, roles can be assigned at folder levels.
