bash - How to use sudo in build script for gitlab ci?

Question

When I would like to do something that requiers sudo privelegies, the build process stucks and when ps aux for that command, it hanging in the list but doing nothing.

E.g.:

in the buildscript:

# stop nginx
echo "INFO: stopping nginx. pid [$(cat /opt/nginx/logs/nginx.pid)]"
sudo kill $(cat /opt/nginx/logs/nginx.pid)

in the gitlab ci output console:

INFO: stopping nginx. pid [2741]

kill $(cat /opt/nginx/logs/nginx.pid) # with a spinning wheel

in the bash:

> ps aux | grep nginx

root      6698  0.0  0.1  37628  1264 ?        Ss   19:25   0:00 nginx: master process /opt/nginx/sbin/nginx
nobody    6700  0.3  0.3  41776  3832 ?        S    19:25   0:00 nginx: worker process
kai   7015  0.0  0.0   4176   580 pts/0    S+   19:27   0:00 sh -c sudo kill $(cat /opt/nginx/logs/nginx.pid)
kai   7039  0.0  0.0   7828   844 pts/2    S+   19:27   0:00 grep nginx

So:

• not the sudo kill $(cat /opt/nginx/logs/nginx.pid) is going to execute, but sh -c sudo kill $(cat /opt/nginx/logs/nginx.pid)
• it is hanging up, without response (sounds for me like it asks for a password interactively)
