Re: [Wrapper-user] How set owner/group on log file

[Etienne J. <lap...@gm...>]

Hello.

In fact, I am using Wrapper with the projet Jenkins Runner:
https://github.com/mnadeem/JenkinsRunner

The service is run as a specific user, let's say "jenkins".

As I am using it under "Ubuntu", I wanted to centralize logs as it is done.
So I created a folder /var/log/jenkins, and logs are created with name like
jenkins.log.

What I wanted, is to have permissions for owner jenkins, and group adm, as
if I did something like this :
mkdir /var/log/jenkins
chown jenkins:adm /var/log/jenkins

But when log files are created, the ownership is something like
jenkins:jenkins. Group may comes from the default group for user jenkins.
But I do not want to put user jenkins in group adm by default, because this
is not an administrator.

So in fact, this is not a matter of changing the owner (my bad for the
description), but more changing the group.

If not possible, I will find a way to do it with configuration on the LInux
system.

Etienne Jouvin
