Is it possible to run GitLab Runner in debug/verbose mode. From a terminal, run:
gitlab-runner --debug run
Debug logging can be enabled in the global section of the
config.toml by setting the
log_level setting to
## Configure GitLab Runner's logging level. Available values are: debug, info, warn, error, fatal, panic ## ref: https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-global-section ## logLevel: debug
Please see the self-signed certificates.
If you want to use Docker executor,
and you are connecting to Docker Engine installed on server.
You can see the
Permission Denied error.
The most likely cause is that your system uses SELinux (enabled by default on CentOS, Fedora and RHEL).
Check your SELinux policy on your system for possible denials.
This most likely happens, because of the broken AUFS storage driver: Java process hangs on inside container. The best solution is to change the storage driver to either OverlayFS (faster) or DeviceMapper (slower).
This happens due to fact that runner uses
Transfer-Encoding: chunked which is broken on early version of NGINX (https://serverfault.com/questions/164220/is-there-a-way-to-avoid-nginx-411-content-length-required-errors).
Upgrade your NGINX to newer version. For more information see this issue: https://gitlab.com/gitlab-org/gitlab-runner/-/issues/1031
git clone using HTTP(s) (with GitLab Runner or manually for
tests) and you see the following output:
$ git clone https://git.example.com/user/repo.git Cloning into 'repo'... warning: You appear to have cloned an empty repository.
Make sure, that the configuration of the HTTP Proxy in your GitLab server installation is done properly. Especially if you are using some HTTP Proxy with its own configuration, make sure that GitLab requests are proxied to the GitLab Workhorse socket, not to the GitLab Unicorn socket.
Git protocol via HTTP(S) is resolved by the GitLab Workhorse, so this is the main entrypoint of GitLab.
If you are using Omnibus GitLab, but don’t want to use the bundled NGINX server, please read using a non-bundled web-server.
In the GitLab Recipes repository there are web-server configuration examples for Apache and NGINX.
If you are using GitLab installed from source, please also read the above documentation and examples, and make sure that all HTTP(S) traffic is going through the GitLab Workhorse.
It’s possible to configure the timezone in which
are described. This feature should work on most Unix systems out of the box. However on some
Unix systems, and probably on most non-Unix systems (including Windows, for which we’re providing
Runner’s binaries), when used, the Runner will crash at start with an error similar to:
Failed to load config Invalid OffPeakPeriods value: open /usr/local/go/lib/time/zoneinfo.zip: no such file or directory
The error is caused by the
time package in Go. Go uses the IANA Time Zone database to load
the configuration of the specified timezone. On most Unix systems, this database is already present on
one of well-known paths (
time package looks for the Time Zone database in all those three paths. If it doesn’t find any
of them, but the machine has a configured Go development environment, then it will fallback to
If none of those paths are present (for example on a production Windows host) the above error is thrown.
In case your system has support for the IANA Time Zone database, but it’s not available by default, you can try to install it. For Linux systems it can be done for example by:
# on Debian/Ubuntu based systems sudo apt-get install tzdata # on RPM based systems sudo yum install tzdata # on Linux Alpine sudo apk add -U tzdata
If your system doesn’t provide this database in a native way, then you can make
working by following the steps below:
zoneinfo.zip. Starting with version v9.1.0 you can download the file from a tagged path. In that case you should replace
latestwith the tag name (e.g.,
v9.1.0) in the
Store this file in a well known directory. We’re suggesting to use the same directory where the
config.tomlfile is present. So for example, if you’re hosting Runner on Windows machine and your configuration file is stored at
C:\gitlab-runner\config.toml, then save the
ZONEINFOenvironment variable containing a full path to the
zoneinfo.zipfile. If you are starting the Runner using the
runcommand, then you can do this with:
ZONEINFO=/etc/gitlab-runner/zoneinfo.zip gitlab-runner run <other options ...>
or if using Windows:
C:\gitlab-runner> set ZONEINFO=C:\gitlab-runner\zoneinfo.zip C:\gitlab-runner> gitlab-runner run <other options ...>
If you are starting the Runner as a system service then you will need to update/override the service configuration in a way that is provided by your service manager software (unix systems) or by adding the
ZONEINFOvariable to the list of environment variables available for Runner’s user through System Settings (Windows).
You can, but not sharing the same
Running multiple instances of Runner using the same configuration file can cause
unexpected and hard-to-debug behavior. In
GitLab Runner 12.2,
only a single instance of Runner can use a specific
config.toml file at
This error is often due to your shell loading your profile, and one of the scripts is causing the failure.
Example of dotfiles that are known to cause failure:
The following relate to Runner troubleshooting on Windows.
This is caused by tools like
npm which will sometimes generate directory structures
with paths more than 260 characters in length. There are two possible fixes you can
adopt to solve the problem.
You can avoid the problem by using Git to clean your directory structure, first run
git config --system core.longpaths true from the command line and then set your
project to use
git fetch from the GitLab CI project settings page.
The NTFSSecurity PowerShell module provides a Remove-Item2 method which supports long paths. The GitLab CI Multi Runner will detect it if it is available and automatically make use of it.
I can’t run Windows BASH scripts; I’m getting
The system cannot find the batch label specified - buildscript
You need to prepend
call to your Batch file line in
.gitlab-ci.yml so that it looks like
call C:\path\to\test.bat. Here
is a more complete example:
before_script: - call C:\path\to\test.bat
Additional info can be found under issue #1025.
Make sure that you have the ANSI color codes in your program’s output. For the purposes of text formatting, assume that you’re running in a UNIX ANSI terminal emulator (because that’s what the webUI’s output is).
The web interface for GitLab CI emulates a UNIX ANSI terminal (at least partially). The
gitlab-runner pipes any output from the build
directly to the web interface. That means that any ANSI color codes that are present will be honored.
Older versions of Windows’ CMD terminal (before Win10 version 1511) do not support
ANSI color codes - they use win32 (
ANSI.SYS) calls instead which are not present in
the string to be displayed. When writing cross-platform programs, a developer will typically use ANSI color codes by default and convert
them to win32 calls when running on a Windows system (example: Colorama).
If your program is doing the above, then you need to disable that conversion for the CI builds so that the ANSI codes remain in the string.
When installing and starting the GitLab Runner service on Windows you can meet with such error:
gitlab-runner install --password WINDOWS_MACHINE_PASSWORD gitlab-runner start FATA Failed to start GitLab Runner: The service did not start due to a logon failure.
This error can occur when the user used to execute the service doesn’t have
SeServiceLogonRight permission. In such case you need to add this
permission for the chosen user and then try to start the service again.
You can add
SeServiceLogonRight in two ways:
- Manually using Administrative Tools:
- Go to Control Panel > System and Security > Administrative Tools,
- open the Local Security Policy tool,
- chose the Security Settings > Local Policies > User Rights Assignment on the list on the left,
- open the Log on as a service on the list on the right,
- click on the Add User or Group… button,
add the user (“by hand” or using Advanced… button) and apply the settings.

GitLab Runner checks the version of Windows Server to verify that it’s supported.
It does this by running
If GitLab Runner fails to start with the following error, but with no Windows Server version specified, then the likely root cause is that the Docker version is too old.
Preparation failed: detecting base image: unsupported Windows Version: Windows Server Datacenter
The error should contain detailed information about the Windows Server version, which is then compared with the versions that GitLab Runner supports.
unsupported Windows Version: Windows Server Datacenter Version 1909 (OS Build 18363.720)
Docker 17.06.2 on Windows Server 1909 returns the following in the output
Operating System: Windows Server Datacenter
The fix in this case is to upgrade the Docker version. Read more about supported Docker versions.
If GitLab Runner is not being run under an administrator account and instead is using a
standard user account, mapped network drives cannot be used and you’ll receive an error stating
The system cannot find the path specified. This is because using a service logon session
creates some limitations
on accessing resources for security. Use the
of your drive instead.
The following relate to Runner troubleshooting on macOS.
This message may occur when you try to install GitLab Runner on macOS. Make sure that you manage GitLab Runner service from the GUI Terminal application, not the SSH connection.
If your Runner is stuck on the above message when using macOS, there are two causes to why this happens:
Make sure that your user can perform UI interactions:
DevToolsSecurity -enable sudo security authorizationdb remove system.privilege.taskport is-developer
The first command enables access to developer tools for your user. The second command allows the user who is member of the developer group to do UI interactions, e.g., run the iOS simulator.
Make sure that your Runner service doesn’t use
SessionCreate = true. Previously, when running GitLab Runner as a service, we were creating
SessionCreate. At that point (Mavericks), this was the only solution to make Code Signing work. That changed recently with OS X El Capitan which introduced a lot of new security features that altered this behavior. Since GitLab Runner 1.1, when creating a
LaunchAgent, we don’t set
SessionCreate. However, in order to upgrade, you need to manually reinstall the
gitlab-runner uninstall gitlab-runner install gitlab-runner start
Then you can verify that
fatal: unable to access 'https://path:3000/user/repo.git/': Failed to connect to path port 3000: Operation timed out error in the job
If one of the jobs fails with this error, make sure the Runner can connect to your GitLab instance. The connection could be blocked by things like:
