About variables
Variables provide a way to store and reuse non-sensitive configuration information. You can store any configuration data such as compiler flags, usernames, or server names as variables. Variables are interpolated on the runner machine that runs your workflow. Commands that run in actions or workflow steps can create, read, and modify variables.
You can set your own custom variables or use the default environment variables that GitHub sets automatically. For more information, see "Default environment variables".
You can set a custom variable in two ways.
- To define an environment variable for use in a single workflow, you can use the
env
key in the workflow file. For more information, see "Defining environment variables for a single workflow". - To define a configuration variable across multiple workflows, you can define it at the organization, repository, or environment level. For more information, see "Defining configuration variables for multiple workflows".
Warning: By default, variables render unmasked in your build outputs. If you need greater security for sensitive information, such as passwords, use secrets instead. For more information, see "GitHub Actions에서 비밀 사용".
Defining environment variables for a single workflow
To set a custom environment variable for a single workflow, you can define it using the env
key in the workflow file. The scope of a custom variable set by this method is limited to the element in which it is defined. You can define variables that are scoped for:
- The entire workflow, by using
env
at the top level of the workflow file. - The contents of a job within a workflow, by using
jobs.<job_id>.env
. - A specific step within a job, by using
jobs.<job_id>.steps[*].env
.
name: Greeting on variable day on: workflow_dispatch env: DAY_OF_WEEK: Monday jobs: greeting_job: runs-on: ubuntu-latest env: Greeting: Hello steps: - name: "Say Hello Mona it's Monday" run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!" env: First_Name: Mona
name: Greeting on variable day
on:
workflow_dispatch
env:
DAY_OF_WEEK: Monday
jobs:
greeting_job:
runs-on: ubuntu-latest
env:
Greeting: Hello
steps:
- name: "Say Hello Mona it's Monday"
run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!"
env:
First_Name: Mona
You can access env
variable values using runner environment variables or using contexts. The example above shows three custom variables being used as runner environment variables in an echo
command: $DAY_OF_WEEK
, $Greeting
, and $First_Name
. The values for these variables are set, and scoped, at the workflow, job, and step level respectively. The interpolation of these variables happens on the runner.
The commands in the run
steps of a workflow, or a referenced action, are processed by the shell you are using on the runner. The instructions in the other parts of a workflow are processed by GitHub Actions and are not sent to the runner. You can use either runner environment variables or contexts in run
steps, but in the parts of a workflow that are not sent to the runner you must use contexts to access variable values. For more information, see "Using contexts to access variable values."
Because runner environment variable interpolation is done after a workflow job is sent to a runner machine, you must use the appropriate syntax for the shell that's used on the runner. In this example, the workflow specifies ubuntu-latest
. By default, Linux runners use the bash shell, so you must use the syntax $NAME
. By default, Windows runners use PowerShell, so you would use the syntax $env:NAME
. For more information about shells, see "GitHub Actions에 대한 워크플로 구문."
Naming conventions for environment variables
When you set an environment variable, you cannot use any of the default environment variable names. For a complete list of default environment variables, see "Default environment variables" below. If you attempt to override the value of one of these default variables, the assignment is ignored.
Note: You can list the entire set of environment variables that are available to a workflow step by using run: env
in a step and then examining the output for the step.
Defining configuration variables for multiple workflows
참고: GitHub Actions에 대한 구성 변수는 beta 버전이며 변경될 수 있습니다.
You can create configuration variables for use across multiple workflows, and can define them at either the organization, repository, or environment level.
For example, you can use configuration variables to set default values for parameters passed to build tools at an organization level, but then allow repository owners to override these parameters on a case-by-case basis.
When you define configuration variables, they are automatically available in the vars
context. For more information, see "Using the vars
context to access configuration variable values".
Configuration variable precedence
If a variable with the same name exists at multiple levels, the variable at the lowest level takes precedence. For example, if an organization-level variable has the same name as a repository-level variable, then the repository-level variable takes precedence. Similarly, if an organization, repository, and environment all have a variable with the same name, the environment-level variable takes precedence.
For reusable workflows, the variables from the caller workflow's repository are used. Variables from the repository that contains the called workflow are not made available to the caller workflow.
Naming conventions for configuration variables
The following rules apply to configuration variable names:
- 비밀 이름에는 영숫자 문자(
[a-z]
,[A-Z]
,[0-9]
) 또는 밑줄(_
)만 사용할 수 있습니다. 공백은 사용할 수 없습니다. - 비밀 이름은
GITHUB_
접두사로 시작할 수 없습니다. - 비밀 이름은 숫자로 시작할 수 없습니다.
- 이름은 대/소문자를 구분하지 않습니다.
- 비밀 이름은 해당 수준에서 고유해야 합니다.

Limits for configuration variables
Individual variables are limited to 48 KB in size.
You can store up to 1,000 organization variables, 500 variables per repository, and 100 variables per environment. The total combined size limit for organization and repository variables is 10 MB per workflow run.
A workflow created in a repository can access the following number of variables:
- Up to 500 repository variables, if the total size of repository variables is less than 10 MB. If the total size of repository variables exceeds 10 MB, only the repository variables that fall below the limit will be available (as sorted alphabetically by variable name).
- Up to 1,000 organization variables, if the total combined size of repository and organization variables is less than 10 MB. If the total combined size of organization and repository variables exceeds 10 MB, only the organization variables that fall below that limit will be available (after accounting for repository variables and as sorted alphabetically by variable name).
- Up to 100 environment-level variables.
Note: Environment-level variables do not count toward the 10 MB total size limit. If you exceed the combined size limit for repository and organization variables and still need additional variables, you can use an environment and define additional variables in the environment.
Using contexts to access variable values
컨텍스트는 워크플로 실행, 변수, 실행기 환경, 작업 및 단계에 대한 정보에 액세스하는 방법입니다. For more information, see "Accessing contextual information about workflow runs". There are many other contexts that you can use for a variety of purposes in your workflows. For details of where you can use specific contexts within a workflow, see "Accessing contextual information about workflow runs."
You can access environment variable values using the env
context and configuration variable values using the vars
context.
Using the env
context to access environment variable values
In addition to runner environment variables, GitHub Actions allows you to set and read env
key values using contexts. Environment variables and contexts are intended for use at different points in the workflow.
The run
steps in a workflow, or in a referenced action, are processed by a runner. As a result, you can use runner environment variables here, using the appropriate syntax for the shell you are using on the runner - for example, $NAME
for the bash shell on a Linux runner, or $env:NAME
for PowerShell on a Windows runner. In most cases you can also use contexts, with the syntax ${{ CONTEXT.PROPERTY }}
, to access the same value. The difference is that the context will be interpolated and replaced by a string before the job is sent to a runner.
However, you cannot use runner environment variables in parts of a workflow that are processed by GitHub Actions and are not sent to the runner. Instead, you must use contexts. For example, an if
conditional, which determines whether a job or step is sent to the runner, is always processed by GitHub Actions. You must therefore use a context in an if
conditional statement to access the value of an variable.
name: Conditional env variable on: workflow_dispatch env: DAY_OF_WEEK: Monday jobs: greeting_job: runs-on: ubuntu-latest env: Greeting: Hello steps: - name: "Say Hello Mona it's Monday" if: ${{ env.DAY_OF_WEEK == 'Monday' }} run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!" env: First_Name: Mona
name: Conditional env variable
on: workflow_dispatch
env:
DAY_OF_WEEK: Monday
jobs:
greeting_job:
runs-on: ubuntu-latest
env:
Greeting: Hello
steps:
- name: "Say Hello Mona it's Monday"
if: ${{ env.DAY_OF_WEEK == 'Monday' }}
run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!"
env:
First_Name: Mona
In this modification of the earlier example, we've introduced an if
conditional. The workflow step is now only run if DAY_OF_WEEK
is set to "Monday". We access this value from the if
conditional statement by using the env
context. The env
context is not required for the variables referenced within the run
command. They are referenced as runner environment variables and are interpolated after the job is received by the runner. We could, however, have chosen to interpolate those variables before sending the job to the runner, by using contexts. The resulting output would be the same.
run: echo "${{ env.Greeting }} ${{ env.First_Name }}. Today is ${{ env.DAY_OF_WEEK }}!"
Note: Contexts are usually denoted using the dollar sign and curly braces, as ${{ context.property }}
. In an if
conditional, the ${{
and }}
are optional, but if you use them they must enclose the entire comparison statement, as shown above.
You will commonly use either the env
or github
context to access variable values in parts of the workflow that are processed before jobs are sent to runners.
Context | Use case | Example |
---|---|---|
env | Reference custom variables defined in the workflow. | ${{ env.MY_VARIABLE }} |
github | Reference information about the workflow run and the event that triggered the run. | ${{ github.repository }} |
경고: 워크플로 및 작업을 만들 때 코드가 가능한 공격자의 신뢰할 수 없는 입력을 실행할 수 있는지 항상 고려해야 합니다. 공격자가 자신의 악성 콘텐츠를 삽입할 수 있으므로 특정 컨텍스트는 신뢰할 수 없는 입력으로 처리되어야 합니다. 자세한 내용은 "GitHub Actions에 대한 보안 강화"을(를) 참조하세요.
Using the vars
context to access configuration variable values
Configuration variables can be accessed across the workflow using vars
context. For more information, see "Accessing contextual information about workflow runs".
구성 변수가 설정되지 않은 경우, 변수를 참조하는 컨텍스트는 빈 문자열을 반환합니다.

Default environment variables
The default environment variables that GitHub sets are available to every step in a workflow.
Because default environment variables are set by GitHub and not defined in a workflow, they are not accessible through the env
context. However, most of the default variables have a corresponding, and similarly named, context property. For example, the value of the GITHUB_REF
variable can be read during workflow processing using the ${{ github.ref }}
context property.
GITHUB_*

(으)로 덮어쓸 수 있습니다. 그러나, 이것이 항상 가능할 것이라고 보장되지는 않습니다. For more information about setting environment variables, see "Defining environment variables for a single workflow" and "GitHub Actions에 대한 워크플로 명령."
We strongly recommend that actions use variables to access the filesystem rather than using hardcoded file paths. GitHub sets variables for actions to use in all runner environments.
Variable | Description |
---|---|
CI | Always set to true . |
GITHUB_ACTION | The name of the action currently running, or the id of a step. For example, for an action, __repo-owner_name-of-action-repo .GitHub removes special characters, and uses the name __run when the current step runs a script without an id . If you use the same script or action more than once in the same job, the name will include a suffix that consists of the sequence number preceded by an underscore. For example, the first script you run will have the name __run , and the second script will be named __run_2 . Similarly, the second invocation of actions/checkout will be actionscheckout2 . |
GITHUB_ACTION_PATH | The path where an action is located. This property is only supported in composite actions. You can use this path to change directories to where the action is located and access other files in that same repository.

Note: If you need to use a workflow run's URL from within a job, you can combine these variables: $GITHUB_SERVER_URL/$GITHUB_REPOSITORY/actions/runs/$GITHUB_RUN_ID
Detecting the operating system
You can write a single workflow file that can be used for different operating systems by using the RUNNER_OS
default environment variable and the corresponding context property ${{ runner.os }}
. For example, the following workflow could be run successfully if you changed the operating system from macos-latest
to windows-latest
without having to alter the syntax of the environment variables, which differs depending on the shell being used by the runner.
on: workflow_dispatch jobs: if-Windows-else: runs-on: macos-latest steps: - name: condition 1 if: runner.os == 'Windows' run: echo "The operating system on the runner is $env:RUNNER_OS." - name: condition 2 if: runner.os != 'Windows' run: echo "The operating system on the runner is not Windows, it's $RUNNER_OS."
on: workflow_dispatch
jobs:
if-Windows-else:
runs-on: macos-latest
steps:
- name: condition 1
if: runner.os == 'Windows'
run: echo "The operating system on the runner is $env:RUNNER_OS."
- name: condition 2
if: runner.os != 'Windows'
run: echo "The operating system on the runner is not Windows, it's $RUNNER_OS."
In this example, the two if
statements check the os
property of the runner
context to determine the operating system of the runner. if
conditionals are processed by GitHub Actions, and only steps where the check resolves as true
are sent to the runner. Here one of the checks will always be true
and the other false
, so only one of these steps is sent to the runner. Once the job is sent to the runner, the step is executed and the environment variable in the echo
command is interpolated using the appropriate syntax ($env:NAME
for PowerShell on Windows, and $NAME
for bash and sh on Linux and macOS). In this example, the statement runs-on: macos-latest
means that the second step will be run.
Passing values between steps and jobs in a workflow
If you generate a value in one step of a job, you can use the value in subsequent steps of the same job by assigning the value to an existing or new environment variable and then writing this to the GITHUB_ENV
environment file. The environment file can be used directly by an action, or from a shell command in the workflow file by using the run
keyword. For more information, see "GitHub Actions에 대한 워크플로 명령."
If you want to pass a value from a step in one job in a workflow to a step in another job in the workflow, you can define the value as a job output. You can then reference this job output from a step in another job. For more information, see "GitHub Actions에 대한 워크플로 구문."
