How Do I Add a Jenkins User to a Sudo Group?

Adding a Jenkins user to a sudo group allows Jenkins to execute commands with elevated privileges. Here's how you can achieve this:

1. Identify the Sudo Group

• Check existing sudo groups: Use the command sudo groups to list the existing sudo groups on your system.
• Create a new sudo group: If necessary, create a new sudo group specifically for Jenkins using the command sudo groupadd jenkins-sudo.

2. Add Jenkins User to the Group

• Locate the Jenkins user: Determine the username used by your Jenkins installation. This is often jenkins but may differ depending on your setup.
• Add the user to the sudo group: Use the command sudo usermod -aG jenkins-sudo jenkins to add the jenkins user to the jenkins-sudo group.

3. Configure Sudoers File

• Open the sudoers file: Use the command sudo visudo to open the sudoers file in a text editor.
• Add entry for the Jenkins user: Add a line like this: jenkins ALL=(ALL) NOPASSWD: ALL to grant the jenkins user passwordless sudo privileges.

4. Verify Permissions

• Test sudo access: After making these changes, log in as the jenkins user and attempt to run a command with sudo privileges.

Note: Always exercise caution when modifying the sudoers file. Incorrect changes can lock you out of your system.
