GitLab CI/CD Variables
When receiving a job from GitLab CI, the Runner prepares the build environment. It starts by setting a list of predefined variables (environment variables) and a list of user-defined variables.
Priority of variables
The variables can be overwritten and they take precedence over each other in this order:
- Trigger variables or scheduled pipeline variables (take precedence over all)
- Project-level variables or protected variables
- Group-level variables or protected variables
- YAML-defined job-level variables
- YAML-defined global variables
- Deployment variables
- Predefined variables (are the lowest in the chain)
For example, if you define API_TOKEN=secure
as a project variable and
API_TOKEN=yaml
in your .gitlab-ci.yml
, the API_TOKEN
will take the value
secure
as the project variables are higher in the chain.
Unsupported variables
There are cases where some variables cannot be used in the context of a
.gitlab-ci.yml
definition (for example under script
). Read more
about which variables are not supported.
Predefined variables (Environment variables)
Some of the predefined environment variables are available only if a minimum version of GitLab Runner is used. Consult the table below to find the version of Runner required.
NOTE: Note: Starting with GitLab 9.0, we have deprecated some variables. Read the 9.0 Renaming section to find out their replacements. You are strongly advised to use the new variables as we will remove the old ones in future GitLab releases.

9.0 Renaming
To follow conventions of naming across GitLab, and to further move away from the
build
term and toward job
CI variables have been renamed for the 9.0
release.
NOTE: Note:
Starting with GitLab 9.0, we have deprecated the $CI_BUILD_*
variables. You are
strongly advised to use the new variables as we will remove the old ones in
future GitLab releases.

.gitlab-ci.yml
defined variables
NOTE Note: This feature requires GitLab Runner 0.5.0 or higher and GitLab CI 7.14 or higher.
GitLab CI allows you to add to .gitlab-ci.yml
variables that are set in the
build environment. The variables are hence saved in the repository, and they
are meant to store non-sensitive project configuration, e.g., RAILS_ENV
or
DATABASE_URL
.
For example, if you set the variable below globally (not inside a job), it will be used in all executed commands and scripts:
variables:
DATABASE_URL: "postgres://postgres@postgres/my_database"
The YAML-defined variables are also set to all created service containers, thus allowing to fine tune them.
Variables can be defined at a global level, but also at a job level. To turn off global defined variables in your job, define an empty hash:
job_name:
variables: {}
You are able to use other variables inside your variable definition (or escape them with $$
):
variables:
LS_CMD: 'ls $FLAGS $$TMP_DIR'
FLAGS: '-al'
script:
- 'eval $LS_CMD' # will execute 'ls -al $TMP_DIR'
Variables
NOTE: Note: Group-level variables were added in GitLab 9.4.
CAUTION: Important: Be aware that variables are not masked, and their values can be shown in the job logs if explicitly asked to do so. If your project is public or internal, you can set the pipelines private from your project's Pipelines settings. Follow the discussion in issue #13784 for masking the variables.
GitLab CI allows you to define per-project or per-group variables
that are set in the pipeline environment. The variables are stored out of
the repository (not in .gitlab-ci.yml
) and are securely passed to GitLab Runner
making them available during a pipeline run. It's the recommended method to
use for storing things like passwords, SSH keys and credentials.
Project-level variables can be added by going to your project's Settings > CI/CD, then finding the section called Variables.
Likewise, group-level variables can be added by going to your group's Settings > CI/CD, then finding the section called Variables. Any variables of subgroups will be inherited recursively.
Once you set them, they will be available for all subsequent pipelines. You can also protect your variables.
Protected variables
Notes: This feature requires GitLab 9.3 or higher.
Variables could be protected. Whenever a variable is protected, it would only be securely passed to pipelines running on the protected branches or protected tags. The other pipelines would not get any protected variables.
Protected variables can be added by going to your project's Settings > CI/CD, then finding the section called Variables, and check "Protected".
Once you set them, they will be available for all subsequent pipelines.
Manually-specified variables
Introduced in GitLab 10.8.
Variables can be specified for a single pipeline run when a manual pipeline is created.
Deployment variables
NOTE: Note: This feature requires GitLab CI 8.15 or higher.
Project services that are responsible for deployment configuration may define their own variables that are set in the build environment. These variables are only defined for deployment jobs. Please consult the documentation of the project services that you are using to learn which variables they define.
An example project service that defines deployment variables is the Kubernetes integration.
Debug tracing
Introduced in GitLab Runner 1.7.
CAUTION: Warning: Enabling debug tracing can have severe security implications. The output will contain the content of all your variables and any other secrets! The output will be uploaded to the GitLab server and made visible in job traces!
By default, GitLab Runner hides most of the details of what it is doing when processing a job. This behavior keeps job traces short, and prevents secrets from being leaked into the trace unless your script writes them to the screen.
If a job isn't working as expected, this can make the problem difficult to
investigate; in these cases, you can enable debug tracing in .gitlab-ci.yml
.
Available on GitLab Runner v1.7+, this feature enables the shell's execution
trace, resulting in a verbose job trace listing all commands that were run,
variables that were set, etc.
Before enabling this, you should ensure jobs are visible to team members only. You should also erase all generated job traces before making them visible again.
To enable debug traces, set the CI_DEBUG_TRACE
variable to true
:
job_name:
variables:
CI_DEBUG_TRACE: "true"
Example truncated output with debug trace set to true:
...

Using the CI variables in your job scripts
All variables are set as environment variables in the build environment, and
they are accessible with normal methods that are used to access such variables.
In most cases bash
or sh
is used to execute the job script.
To access environment variables, use the syntax for your Runner's shell.
Shell | Usage |
---|---|
bash/sh | $variable |
windows batch | %variable% |
PowerShell | $env:variable |
To access environment variables in bash, prefix the variable name with ($
):
job_name:
script:
- echo $CI_JOB_ID
To access environment variables in Windows Batch, surround the variable
with (%
):
job_name:
script:
- echo %CI_JOB_ID%
To access environment variables in a Windows PowerShell environment, prefix
the variable name with ($env:
):
job_name:
script:
- echo $env:CI_JOB_ID
You can also list all environment variables with the export
command,
but be aware that this will also expose the values of all the variables
you set, in the job log:
job_name:
script:
- export
Example values:
export CI_JOB_ID="50"

Variables expressions
Variables expressions were added in GitLab 10.7.
It is possible to use variables expressions with only / except policies in
.gitlab-ci.yml
. By using this approach you can limit what jobs are going to
be created within a pipeline after pushing a code to GitLab.
This is particularly useful in combination with variables and triggered pipeline variables.
deploy:
script: cap staging deploy
environment: staging
only:
variables:
- $RELEASE == "staging"
- $STAGING
Each expression provided is going to be evaluated before creating a pipeline.
If any of the conditions in variables
evaluates to truth when using only
,
a new job is going to be created. If any of the expressions evaluates to truth
when except
is being used, a job is not going to be created.
This follows usual rules for only
/ except
policies.
Supported syntax
Below you can find supported syntax reference:
-
Equality matching using a string
Example:
$VARIABLE == "some value"
You can use equality operator
==
to compare a variable content to a string. We support both, double quotes and single quotes to define a string value, so both$VARIABLE == "some value"
and$VARIABLE == 'some value'
are supported."some value" == $VARIABLE
is correct too. -
Checking for an undefined value
Example:
$VARIABLE == null
It sometimes happens that you want to check whether a variable is defined or not. To do that, you can compare a variable to
null
keyword, like$VARIABLE == null
. This expression is going to evaluate to truth if variable is not defined. -
Checking for an empty variable
Example:
$VARIABLE == ""
If you want to check whether a variable is defined, but is empty, you can simply compare it against an empty string, like
$VAR == ''
. -
Comparing two variables
Example:
$VARIABLE_1 == $VARIABLE_2
It is possible to compare two variables. This is going to compare values of these variables.
-
Variable presence check
Example:
$STAGING
If you only want to create a job when there is some variable present, which means that it is defined and non-empty, you can simply use variable name as an expression, like
$STAGING
. If$STAGING
variable is defined, and is non empty, expression will evaluate to truth.$STAGING
value needs to a string, with length higher than zero. Variable that contains only whitespace characters is not an empty variable. -
Pattern matching (added in 11.0)
Example:
$VARIABLE =~ /^content.*/
It is possible perform pattern matching against a variable and regular expression. Expression like this evaluates to truth if matches are found.
Pattern matching is case-sensitive by default. Use
i
flag modifier, like/pattern/i
to make a pattern case-insensitive.
