To find out which user GitLab Runner is installed under, you can check the ownership of the GitLab Runner binary or files associated with the GitLab Runner installation.
Here are a few methods you can use to determine the user:
Check GitLab Runner Binary Ownership: You can check the ownership of the GitLab Runner binary itself. Typically, GitLab Runner is installed under a specific user’s home directory. Run the following command to check the ownership of the GitLab Runner binary:
ls -l $(which gitlab-runner)
This command will display information about the GitLab Runner binary, including the user and group ownership.
Check GitLab Runner Configuration Directory Ownership: GitLab Runner may also have associated configuration files or directories that are owned by the user who installed it. You can check the ownership of the configuration directory (e.g., /etc/gitlab-runner/) using the ls -l command.
Check GitLab Runner Service Configuration: If GitLab Runner is installed as a service, you can check the service configuration file to see which user it’s configured to run under. For systemd-based systems, you can find the service file in /etc/systemd/system/ or /lib/systemd/system/. Look for files with names like gitlab-runner.service and examine the User= parameter.
cat /etc/systemd/system/gitlab-runner.service | grep User=
Check Running Processes: You can also check the currently running processes to see which user is running the GitLab Runner service. Run the following command to list all processes related to GitLab Runner:
ps aux | grep gitlab-runner
This command will show the user associated with the GitLab Runner processes.
