GitLab Runner commands | GitLab Docs

Tier: Free, Premium, Ultimate
Offering: GitLab.com, GitLab Self-Managed, GitLab Dedicated

GitLab Runner contains a set of commands you use to register, manage, and run your builds.

You can check the list of commands by executing:

Append --help after a command to see its specific help page:

gitlab-runner <command> --help

Using environment variables

Most of the commands support environment variables as a method to pass the configuration to the command.

You can see the name of the environment variable when invoking --help for a specific command. For example, you can see below the help message for the run command:

The output is similar to:

NAME:
   gitlab-runner run - run multi runner service

USAGE:
   gitlab-runner run [command options] [arguments...]

OPTIONS:
   -c, --config "/Users/ayufan/.gitlab-runner/config.toml"      Config file [$CONFIG_FILE]

Running in debug mode

When you’re looking for the cause of an undefined behavior or error, use debug mode.

To run a command in debug mode, prepend the command with --debug:

gitlab-runner --debug <command>

Super-user permission

Commands that access the configuration of GitLab Runner behave differently when executed as super-user (root). The file location depends on the user executing the command.

When you execute gitlab-runner commands, you see the mode it is running in:

$ gitlab-runner run

INFO[0000] Starting multi-runner from /Users/ayufan/.gitlab-runner/config.toml ...  builds=0
WARN[0000] Running in user-mode.
WARN[0000] Use sudo for system-mode:
WARN[0000] $ sudo gitlab-runner...

You should use user-mode if you are sure this is the mode you want to work with. Otherwise, prefix your command with sudo:

$ sudo gitlab-runner run

INFO[0000] Starting multi-runner from /etc/gitlab-runner/config.toml ...  builds=0
INFO[0000] Running in system-mode.

In the case of Windows, you may need to run the command prompt as an administrator.

Configuration file

GitLab Runner configuration uses the TOML format.

You can find the file to be edited:

On *nix systems when GitLab Runner is executed as super-user (root): /etc/gitlab-runner/config.toml
On *nix systems when GitLab Runner is executed as non-root: ~/.gitlab-runner/config.toml
On other systems: ./config.toml

Most of the commands accept an argument to specify a custom configuration file, so you can have a multiple different configurations on a single machine. To specify a custom configuration file, use the -c or --config flag, or use the CONFIG_FILE environment variable.

Signals

You can use system signals to interact with GitLab Runner. The following commands support the following signals:

Command Signal Action register SIGINT Cancel runner registration and delete if it was already registered. run, run-single SIGINT, SIGTERM Abort all running builds and exit as soon as possible. Use twice to exit now (forceful shutdown). run, run-single SIGQUIT Stop accepting new builds. Exit as soon as the running builds finish (graceful shutdown). run SIGHUP Force to reload configuration file.

For example, to force a reload of a runner’s configuration file, run:

sudo kill -SIGHUP <main_runner_pid>

For graceful shutdowns:

sudo kill -SIGQUIT <main_runner_pid>

Do not use killall or pkill for graceful shutdowns if you are using shell or docker executors. This can cause improper handling of the signals due to sub-processes being killed as well. Use it only on the main process handling the jobs.

Some operating systems are configured to automatically restart services when they fail (which is the default on some platforms). If your operating system has this configuration, it might automatically restart the runner if it is shut down by the signals above.

Below we explain what each command does in detail.

Use the following commands to register a new runner, or list and verify them if they are still registered.

These commands support the following arguments:

gitlab-runner register

This command registers your runner in GitLab by using the GitLab Runners API.

The registered runner is added to the configuration file. You can use multiple configurations in a single installation of GitLab Runner. Executing gitlab-runner register adds a new configuration entry. It doesn’t remove the previous ones.

You can register a runner:

interactively.
non-interactively.

Runners can be registered directly by using the GitLab Runners API but configuration is not generated automatically.

Interactive registration

This command is usually used in interactive mode (default). You are asked multiple questions during a runner’s registration.

This question can be pre-filled by adding arguments when invoking the registration command:

gitlab-runner register --name my-runner --url "http://gitlab.example.com" --token my-authentication-token

Or by configuring the environment variable before the register command:

export CI_SERVER_URL=http://gitlab.example.com
export RUNNER_NAME=my-runner
export CI_SERVER_TOKEN=my-authentication-token
gitlab-runner register

To check all possible arguments and environments execute:

gitlab-runner register --help

Non-interactive registration

It’s possible to use registration in non-interactive / unattended mode.

You can specify the arguments when invoking the registration command:

gitlab-runner register --non-interactive <other-arguments>

Or by configuring the environment variable before the register command:

<other-environment-variables>
export REGISTER_NON_INTERACTIVE=true
gitlab-runner register

Boolean parameters must be passed in the command line with --key={true|false}.

[[runners]] configuration template file

History

Introduced in GitLab Runner 12.2.

Additional options can be configured during runner registration by using the configuration template file feature.

gitlab-runner list

This command lists all runners saved in the configuration file.

gitlab-runner verify

This command verifies that the registered runners can connect to GitLab. But, it doesn’t verify if the runners are being used by the GitLab Runner service. An example output is:

Verifying runner... is alive                        runner=fee9938e
Verifying runner... is alive                        runner=0db52b31
Verifying runner... is alive                        runner=826f687f
Verifying runner... is alive                        runner=32773c0f

To remove the old runners that have been removed from GitLab, execute the following command.

This operation cannot be undone. It updates the configuration file, so make sure to have a backup of config.toml before executing it.

gitlab-runner verify --delete

gitlab-runner unregister

This command unregisters registered runners by using the GitLab Runners API.

It expects either:

A full URL and the runner’s token.
The runner’s name.

With the --all-runners option, it unregisters all the attached runners.

Runners can be unregistered with the GitLab Runners API but the configuration is not modified for the user.

If the runner was created with a runner registration token, gitlab-runner unregister with the runner authentication token deletes the runner.
If the runner was created in the GitLab UI or with the Runners API, gitlab-runner unregister with the runner authentication token deletes the runner manager, but not the runner. To completely remove the runner, delete the runner in the runners administration page or use the DELETE /runners REST API endpoint.

To unregister a single runner, first get the runner’s details by executing gitlab-runner list:

test-runner     Executor=shell Token=t0k3n URL=http://gitlab.example.com

Then use this information to unregister it, using one of the following commands.

This operation cannot be undone. It updates the configuration file, so make sure to have a backup of config.toml before executing it.

By URL and token

gitlab-runner unregister --url "http://gitlab.example.com/" --token t0k3n

By name

gitlab-runner unregister --name test-runner

If there is more than one runner with the given name, only the first one is removed.

All runners

gitlab-runner unregister --all-runners

gitlab-runner reset-token

This command resets a runner’s token by using the GitLab Runners API, with either the runner ID or the current token.

It expects the runner’s name (or URL and ID), and an optional PAT if resetting by runner ID. The PAT and runner ID are intended to be used if the token has already expired.

With the --all-runners option, it resets all the attached runners’ tokens.

With runner’s current token

gitlab-runner reset-token --name test-runner

With PAT and runner name

gitlab-runner reset-token --name test-runner --pat PaT

With PAT, GitLab URL, and runner ID

gitlab-runner reset-token --url "https://gitlab.example.com/" --id 12345 --pat PaT

All runners

gitlab-runners reset-token --all-runners

The following commands allow you to manage the runner as a system or user service. Use them to install, uninstall, start, and stop the runner service.

All service related commands accept these arguments:

Parameter Default Description --service gitlab-runner Specify custom service name --config See the configuration file Specify a custom configuration file to use --user-service See user service Configure GitLab Runner to run as a user service (systemd) gitlab-runner install

This command installs GitLab Runner as a service. It accepts different sets of arguments depending on which system it’s run on.

When run on Windows or as super-user, it accepts the --user flag which allows you to drop privileges of builds run with the shell executor.

Parameter Default Description --service gitlab-runner Specify service name to use --config See the configuration file Specify a custom configuration file to use --syslog true (for non systemd systems) Specify if the service should integrate with system logging service --working-directory the current directory Specify the root directory where all data is stored when builds are run with the shell executor --user root Specify the user that executes the builds --password none Specify the password for the user that executes the builds gitlab-runner uninstall

This command stops and uninstalls GitLab Runner from being run as an service.

gitlab-runner start

This command starts the GitLab Runner service.

gitlab-runner stop

This command stops the GitLab Runner service.

gitlab-runner restart

This command stops and then starts the GitLab Runner service.

gitlab-runner status

This command prints the status of the GitLab Runner service. The exit code is zero when the service is running and non-zero when the service is not running.

Multiple services

By specifying the --service flag, it is possible to have multiple GitLab Runner services installed, with multiple separate configurations.

User service

You can use some init systems (like systemd) to manage services as user services. If your init system provides this feature and you want to manage the gitlab-runner service as a user service, specify the --user-service flag when you run service-related commands.

This command allows to fetch and process builds from GitLab.

gitlab-runner run

The gitlab-runner run command is the main command that is executed when GitLab Runner is started as a service. It reads all defined runners from config.toml and tries to run all of them.

The command is executed and works until it receives a signal.

It accepts the following parameters.

Parameter Default Description --config See configuration-file Specify a custom configuration file to be used --working-directory the current directory Specify the root directory where all data is stored when builds run with the shell executor --user the current user Specify the user that executes builds --syslog false Send all logs to SysLog (Unix) or EventLog (Windows) --listen-address empty Address (<host>:<port>) on which the Prometheus metrics HTTP server should be listening gitlab-runner run-single

History

Ability to use a configuration file introduced in GitLab Runner 17.1.

Use this supplementary command to run a single build from a single GitLab instance. It can:

Take all options either as CLI parameters or environment variables, including the GitLab URL and Runner token. For example, a single job with all parameters specified explicitly:
```
gitlab-runner run-single -u http://gitlab.example.com -t my-runner-token --executor docker --docker-image ruby:3.3
```
Read from a configuration file to use a specific runner’s configuration. For example, a single job with a configuration file:
```
gitlab-runner run-single -c ~/.gitlab-runner/config.toml -r runner-name
```

You can see all possible configuration options by using the --help flag:

gitlab-runner run-single --help

You can use the --max-builds option to control how many builds the runner executes before exiting. The default of 0 means that the runner has no build limit and jobs run forever.

You can also use the --wait-timeout option to control how long the runner waits for a job before exiting. The default of 0 means that the runner has no timeout and waits forever between jobs.

Internal commands

GitLab Runner is distributed as a single binary and contains a few internal commands that are used during builds.

gitlab-runner artifacts-downloader

Download the artifacts archive from GitLab.

gitlab-runner artifacts-uploader

Upload the artifacts archive to GitLab.

gitlab-runner cache-archiver

Create a cache archive, store it locally or upload it to an external server.

Restore the cache archive from a locally or externally stored file.

Troubleshooting

Below are some common pitfalls.

Access Denied when running the service-related commands

Usually the service related commands require administrator privileges:

On Unix (Linux, macOS, FreeBSD) systems, prefix gitlab-runner with sudo
On Windows systems use the elevated command prompt. Run an Administrator command prompt. To write Command Prompt in the Windows search field, right-click and select Run as administrator. Confirm that you want to execute the elevated command prompt.

gitlab-runner stop doesn’t shut down gracefully

When GitLab Runner is installed on a host and runs local executors, it starts additional processes for operations like downloading or uploading artifacts, or handling cache. These processes are executed as gitlab-runner commands, which means that you can use pkill -QUIT gitlab-runner or killall QUIT gitlab-runner to kill them. When you kill them, the operations they are responsible for fail.

Here are two ways to prevent this:

Register the runner as a local service (like systemd) with SIGQUIT as the kill signal, and use gitlab-runner stop or systemctl stop gitlab-runner.service. Here is an example configuration to enable this behavior:
```
; /etc/systemd/system/gitlab-runner.service.d/kill.conf
[Service]
KillSignal=SIGQUIT
TimeoutStopSec=infinity
```
- To apply the configuration change, after you create this file, reload systemd with systemctl daemon-reload.
Manually kill the process with kill -SIGQUIT <pid>. You have to find the pid of the main gitlab-runner process. You can find this by looking at logs, as it’s displayed on startup:
```
$ gitlab-runner run
Runtime platform                                    arch=arm64 os=linux pid=8 revision=853330f9 version=16.5.0
```

Saving system ID state file: access denied

GitLab Runner 15.7 and 15.8 might not start if it lacks write permissions for the directory that contains the config.toml file.

When GitLab Runner starts, it searches for the .runner_system_id file in the directory that contains the config.toml. If it cannot find the .runner_system_id file, it creates a new one. If GitLab Runner doesn’t have write permissions, it fails to start.

To resolve this issue, temporarily allow file write permissions, then run gitlab-runner run. After the .runner_system_id file is created, you can reset the permissions to read-only.
