Roles identify a type or category of user. Admin, developer, read-only are typical roles for Jenkins. Applications like Jenkins Role-based access often assign access and permissions to specific roles rather than individual users as dealing with users can be too fine-grained and it is very hard to manage.

You can see the list of built-in and created roles by clicking the Roles left menu item.

To create a role, click Add Role on this page, enter in the name and description of the role, and click Save.

User role mappings can be assigned individually to each user through the Role Mappings tab for that single user. It is always recommended to map the roles to the group for easy access management for users.

In the above example, we are about to assign the role salesforce-jenkins-dev that was created in the Role creation mentioned above.

Once the role is assigned, you see that the salesforce-jenkins- dev role that is associated with the user shows up in the Effective Roles.
