How to Use Role Based Access in Jenkins for Secure Permissions

To use Role-Based Access Control (RBAC) in Jenkins, install the Role Strategy Plugin, then define roles with specific permissions and assign them to users or groups. This setup helps control who can do what in Jenkins projects and system settings.

Syntax

Jenkins RBAC is configured through the Role Strategy Plugin. You define roles with permissions and assign them to users or groups. The main parts are:

• Global roles: Permissions across Jenkins system.
• Project roles: Permissions limited to specific jobs or folders.
• Assign roles: Link users/groups to roles.

Permissions include actions like read, build, configure, etc.

1. Install 'Role Strategy Plugin' from Jenkins Plugin Manager.
2. Go to 'Manage Jenkins' > 'Manage and Assign Roles' > 'Manage Roles'.
3. Create roles by naming them and selecting permissions.
4. Go to 'Assign Roles' tab and assign roles to users or groups.
5. Save and test permissions by logging in as different users.

Example

This example shows how to create a 'developer' project role with build and read permissions on jobs starting with 'dev-', and assign it to user 'alice'.

1. Install 'Role Strategy Plugin'.

2. Navigate to 'Manage Jenkins' > 'Manage and Assign Roles' > 'Manage Roles'.

3. Under 'Project Roles', add a new role:
   - Role name: developer
   - Pattern: dev-.*
   - Permissions: Job/Read, Job/Build

4. Go to 'Assign Roles' tab.

5. Assign 'developer' role to user 'alice' under 'Project Roles'.

6. Save changes.

7. User 'alice' can now build and view jobs starting with 'dev-'.

Output

Role 'developer' created with permissions Job/Read and Job/Build on jobs matching 'dev-.*'.
User 'alice' assigned to 'developer' role.
User 'alice' can build and view matching jobs.

Common Pitfalls

Common mistakes when using Jenkins RBAC include:

• Not installing the Role Strategy Plugin before trying to configure roles.
• Using incorrect regex patterns for project roles, causing roles to not apply as expected.
• Assigning roles but forgetting to save changes.
• Not testing user permissions after assignment, leading to unexpected access issues.
• Confusing global roles and project roles, which control different scopes.

Wrong pattern example:
- Role pattern: dev*  # Incorrect regex, should be dev-.*

Right pattern example:
- Role pattern: dev-.*  # Correct regex to match jobs starting with 'dev-'

Always save after assigning roles to users.

Quick Reference

Step	Action	Description
1	Install Plugin	Install 'Role Strategy Plugin' from Plugin Manager
2	Create Roles	Define global and project roles with permissions
3	Assign Roles	Assign roles to users or groups
4	Save	Save all changes to apply roles
5	Test	Verify user permissions by logging in as assigned users

Key Takeaways

Install the Role Strategy Plugin to enable role based access control in Jenkins.

Define clear global and project roles with appropriate permissions using regex patterns.

Assign roles carefully to users or groups and always save changes.

Test user access after role assignment to ensure correct permissions.

Use project roles to limit access to specific jobs or folders for better security.
