I'm using Gitlab-ci for my job with Debian jessie image. Firstly, I need install some packages. Everything is ok. Then, I want to change user from root to a non-root user, but su command doesn't work. Below is a test about changing user.
My .gitlab-ci.yml:
image: debian:jessie
test:
script:
- whoami
- adduser --disabled-password --gecos "" builder
- su -l builder
- whoami
My result:
$ whoami
root
$ adduser --disabled-password --gecos "" builder
Adding user `builder' ...
Adding new group `builder' (1000) ...
Adding new user `builder' (1000) with group `builder' ...
Creating home directory `/home/builder' ...
Copying files from `/etc/skel' ...
$ su builder
$ whoami
root
I found an answer for myself:
image: debian:jessie
test:
script:
- whoami
- adduser --disabled-password --gecos "" builder
- su -l builder
- - whoami
+ - su builder -c "whoami"
Using command su <username> -c "<command>" will help running command with <username> user, in case mentioned.
