  Rootuser -->admin user --Dev users (Build view)

                                         --Test users  (view create)

                                         --Devops users (create build view)

Step1:Create job >Select Freestyle project

Step2:

Dashboard >Manage Jenkins >Click Users

Create three like this dev,test,prod

Step3: Create three jobs Dev jobs/Test jobs/Prod Jobs 

One Job Permission (Status,changes,workspace,Build now,Configure,Delete project,Rename)

See below dev user login ,as of now , permission not defined , so showing all 

Before going to give permission need to install pugins Rolebased  authenications >install

User Creation and Management in Jenkins (For Dev team ,members user creation and permission)

Users in Jenkins represent individual team members who need access to the system. Each user can have different levels of access based on their role

Jenkins is a CI/CD automation tool that allows multiple users to build,test and deploy software.

Managin users and role is essential to ensure security,control, and efficiency in a multi-user environment

Benefits of user management 

  Accountability :Track who triggered builds and made changes 

  Security: Restricts access to prevent unauthorized changes 

  Customization: Users can have personalized dashboard and preferences

  Audit & Logging:Prvides logs of users actions for troubleshooting 

User Authentication Options 

 Jenkins internal Database(default)

  LDAP/Active directory 

                                                   Matrix Based  Role

it is for Project based not for the Job base 

Step1: Dashboard >Manage Jenkins >Security 

Authorization > Select Project-based Matrix Authorization strategy 

Add users which is you have dev/test/prod users  give read permission

Step2:

 Go to particular job for dev job select Enabled project-based security, and add user which going give permission to the user ,see here i have added dev user give all permissons

See here one only showing particular job devjob not all jobs, those which we give access ,Build also success status

These are all job list in admin user 

 Dev user as given permission show only Project based 

 For Test user 

For prod 

 That is differece Rolebase and Project Matrix based For Rolebased need to install plugins 

for manage and role permision.
