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 environment variables.
• Other variables.

Priority of variables

Variables of different types can take precedence over other variables, depending on where they are defined.

The order of precedence for variables is (from highest to lowest):

1. Trigger variables or scheduled pipeline variables.
2. Project-level variables or protected variables.
3. Group-level variables or protected variables.
4. YAML-defined job-level variables.
5. YAML-defined global variables.
6. Deployment variables.
7. Predefined environment variables.

For example, you define:

• API_TOKEN=secure as a project variable.
• API_TOKEN=yaml in your .gitlab-ci.yml.

API_TOKEN will take the value secure as the project variables take precedence over those defined in .gitlab-ci.yml.

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 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.

GitLab 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.

8.x name	9.0+ name
CI_BUILD_ID	CI_JOB_ID
CI_BUILD_REF	CI_COMMIT_SHA
CI_BUILD_TAG	CI_COMMIT_TAG
CI_BUILD_BEFORE_SHA	CI_COMMIT_BEFORE_SHA
CI_BUILD_REF_NAME	CI_COMMIT_REF_NAME
CI_BUILD_REF_SLUG	CI_COMMIT_REF_SLUG
CI_BUILD_NAME	CI_JOB_NAME
CI_BUILD_STAGE	CI_JOB_STAGE
CI_BUILD_REPO	CI_REPOSITORY_URL
CI_BUILD_TRIGGERED	CI_PIPELINE_TRIGGERED
CI_BUILD_MANUAL	CI_JOB_MANUAL
CI_BUILD_TOKEN	CI_JOB_TOKEN

.gitlab-ci.yml defined variables

NOTE Note: This feature requires GitLab Runner 0.5.0 or higher and GitLab 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. For example, 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

Group-level variables were introduced 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:

1. Navigating to your project's Settings > CI/CD page.
2. Inputing variable keys and values in the Environment variables section.

Group-level variables can be added by:

1. Navigating to your group's Settings > CI/CD page.
2. Inputing variable keys and values in the Environment variables section. 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

Introduced in GitLab 9.3.

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

Introduced in GitLab 8.15.

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.

Auto DevOps application variables

Introduced in GitLab 11.7.

You can configure Auto DevOps to pass CI variables to the running application by prefixing the key of the variable with K8S_SECRET_.

These prefixed variables will then be available as environment variables on the running application container.

CAUTION: Caution: Variables with multiline values are not currently supported due to limitations with the current Auto DevOps scripting environment.

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

Introduced 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:

1. 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.

2. 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.

3. 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 == ''.

4. Comparing two variables

   Example: $VARIABLE_1 == $VARIABLE_2

   It is possible to compare two variables. This is going to compare values of these variables.

5. 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.

6. 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.
