Role Based Authorization Plugin in Jenkins: What It Is and How It Works

The Role Based Authorization Plugin in Jenkins allows administrators to control user permissions by assigning roles with specific access rights. It helps manage who can do what in Jenkins by grouping permissions into roles and assigning these roles to users or groups.

How It Works

The Role Based Authorization Plugin works like a security guard who checks what each person is allowed to do inside a building. Instead of giving every user individual permissions, you create roles that bundle permissions together, such as 'developer', 'tester', or 'admin'. Each role has specific rights, like creating jobs, viewing builds, or managing plugins.

Once roles are defined, you assign them to users or groups. This way, Jenkins checks a user's roles to decide what actions they can perform. This system makes managing permissions easier and more organized, especially when many users need different levels of access.

Example

This example shows how to define roles and assign them to users in Jenkins using the Role Based Authorization Plugin's UI configuration.

text

1. Go to Jenkins Dashboard > Manage Jenkins > Manage and Assign Roles > Manage Roles.
2. Create a new role named 'developer' with permissions like 'Job/Build', 'Job/Read'.
3. Create another role named 'viewer' with only 'Job/Read' permission.
4. Go to Manage and Assign Roles > Assign Roles.
5. Assign the 'developer' role to user 'alice' and 'viewer' role to user 'bob'.

Output

User 'alice' can create and build jobs; user 'bob' can only view jobs.

When to Use

Use the Role Based Authorization Plugin when you need fine control over user permissions in Jenkins. It is especially useful in teams where different members have different responsibilities, such as developers, testers, and administrators.

For example, you might want developers to create and run jobs but prevent them from changing system settings. Testers might only need to view job results. Admins get full access. This plugin helps enforce these rules easily and securely.

Key Points

• Groups permissions into roles for easier management.
• Assign roles to users or groups to control access.
• Supports fine-grained permission control in Jenkins.
• Improves security by limiting user actions based on roles.

Key Takeaways

Role Based Authorization Plugin organizes Jenkins permissions into roles for easier control.

Assign roles to users to define what actions they can perform in Jenkins.

It helps secure Jenkins by limiting access based on user responsibilities.

Ideal for teams with different access needs like developers, testers, and admins.
