如何在 Linux 的从节点中运行 Jenkins 作业时指定用户

Question

I have a Jenkins master slave configuration in a Centos machine. Previous all the Jenkins jobs were run as the root user in my slave node. Now I see that the jobs are run as another user.

I was trying to figure out the configuration where I can specify the user for a job in the Jenkins slave configuration or in job level.

My job includes code checkouts and folder creations. Since the job is supposed to be executed as different user, I am facing a lot of permission issues. Is there any way to specify the linux user for a jenkins job or node?

Answer 1

The easiest way is to configure whole slave to work as specific user (in node configuration: Nodes -> [your node] -> Configure -> Launch method -> Credentials ) and grant all needed permissions to that user.

If it's not an option you may use sudo to run certain commands as a specific user. Passwords may be stored safely in Jenkins Credentials and injected as environmental variables in job. Then script may look like that ( sudopass is injected secret):

echo $sudopass | sudo -S -u your_user your_command
