industrial_ci: [gitlab-ci] "/bin/bash: /root/ici/ci_main.sh: No such file or directory" error

I try to use insdustrial_ci on gitlab instead of my homemade scripts. But the job failed. It tries to execute a file named /root/ici/ci_main.sh but it does not exist. This path comes from here https://github.com/ros-industrial/industrial_ci/blob/6dfcee82109157888fb93a6619be4022a73162ed/industrial_ci/src/docker.sh#L40 but I don’t know what is this folder named “/root/ici”. Here is the log.
