You can access contexts using the expression syntax. For more information, see [AUTOTITLE](/actions/learn-github-actions/expressions). {% raw %} `${{ <context> }}` {% endraw %} {% data reusables.actions.context-injection-warning %} | Context name | Type | Description | |---------------|------|-------------| | `github` | `object` | Information about the workflow run. For more information, see [`github` context](#github-context). | | `env` | `object` | Contains variables set in a workflow, job, or step. For more information, see [`env` context](#env-context). | | `vars` | `object` | Contains variables set at the repository, organization, or environment levels. For more information, see [`vars` context](#vars-context). | | `job` | `object` | Information about the currently running job. For more information, see [`job` context](#job-context). | | `jobs` | `object` | For reusable workflows only, contains outputs of jobs from the reusable workflow. For more information, see [`jobs` context](#jobs-context). | | `steps` | `object` | Information about the steps that have been run in the current job. For more information, see [`steps` context](#steps-context). | | `runner` | `object` | Information about the runner that is running the current job. For more information, see [`runner` context](#runner-context). | | `secrets` | `object` | Contains the names and values of secrets that are available to a workflow run. For more information, see [`secrets` context](#secrets-context). | | `strategy` | `object` | Information about the matrix execution strategy for the current job. For more information, see [`strategy` context](#strategy-context). | | `matrix` | `object` | Contains the matrix properties defined in the workflow that apply to the current job. For more information, see [`matrix` context](#matrix-context). | | `needs` | `object` | Contains the outputs of all jobs that are defined as a dependency of the current job. For more information, see [`needs` context](#needs-context). | | `inputs` | `object` | Contains the inputs of a reusable or manually triggered workflow. For more information, see [`inputs` context](#inputs-context). | As part of an expression, you can access context information using one of two syntaxes. * Index syntax: `github['sha']` * Property dereference syntax: `github.sha` In order to use property dereference syntax, the property name must start with a letter or `_` and contain only alphanumeric characters, `-`, or `_`. If you attempt to dereference a nonexistent property, it will evaluate to an empty string. ### Determining when to use contexts {% data variables.product.prodname_actions %} includes a collection of variables called _contexts_ and a similar collection of variables called _default variables_. These variables are intended for use at different points in the workflow: * **Default environment variables:** These environment variables exist only on the runner that is executing your job. For more information, see [AUTOTITLE](/actions/learn-github-actions/variables#default-environment-variables). * **Contexts:** You can use most contexts at any point in your workflow, including when _default variables_ would be unavailable. For example, you can use contexts with expressions to perform initial processing before the job is routed to a runner for execution; this allows you to use a context with the conditional `if` keyword to determine whether a step should run. Once the job is running, you can also retrieve context variables from the runner that is executing the job, such as `runner.os`. For details of where you can use various contexts within a workflow, see [Context availability](#context-availability). The following example demonstrates how these different types of variables can be used together in a job: {% raw %} ```yaml copy name: CI on: push jobs: prod-check: if: ${{ github.ref == 'refs/heads/main' }} runs-on: ubuntu-latest steps: - run: echo "Deploying to production server on branch $GITHUB_REF" ``` {% endraw %} In this example, the `if` statement checks the [`github.ref`](/actions/learn-github-actions/contexts#github-context) context to determine the current branch name; if the name is `refs/heads/main`, then the subsequent steps are executed. The `if` check is processed by {% data variables.product.prodname_actions %}, and the job is only sent to the runner if the result is `true`. Once the job is sent to the runner, the step is executed and refers to the [`$GITHUB_REF`](/actions/learn-github-actions/variables#default-environment-variables) variable from the runner. ### Context availability Different contexts are available throughout a workflow run. For example, the `secrets` context may only be used at certain places within a job. In addition, some functions may only be used in certain places. For example, the `hashFiles` function is not available everywhere. The following table lists the restrictions on where each context and special function can be used within a workflow. The listed contexts are only available for the given workflow key, and may not be used anywhere else. Unless listed below, a function can be used anywhere. | Workflow key | Context | Special functions | | ---- | ------- | ----------------- | | `run-name` | `github, inputs, vars` | None | | `concurrency` | `github, inputs, vars` | None | | `env` | `github, secrets, inputs, vars` | None | | `jobs.<job_id>.concurrency` | `github, needs, strategy, matrix, inputs, vars` | None | | `jobs.<job_id>.container` | `github, needs, strategy, matrix, vars, inputs` | None | | `jobs.<job_id>.container.credentials` | `github, needs, strategy, matrix, env, vars, secrets, inputs` | None | | `jobs.<job_id>.container.env.<env_id>` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, inputs` | None | | `jobs.<job_id>.container.image` | `github, needs, strategy, matrix, vars, inputs` | None | | `jobs.<job_id>.continue-on-error` | `github, needs, strategy, vars, matrix, inputs` | None | | `jobs.<job_id>.defaults.run` | `github, needs, strategy, matrix, env, vars, inputs` | None | | `jobs.<job_id>.env` | `github, needs, strategy, matrix, vars, secrets, inputs` | None | | `jobs.<job_id>.environment` | `github, needs, strategy, matrix, vars, inputs` | None | | `jobs.<job_id>.environment.url` | `github, needs, strategy, matrix, job, runner, env, vars, steps, inputs` | None | | `jobs.<job_id>.if` | `github, needs, vars, inputs` | `always, cancelled, success, failure` | | `jobs.<job_id>.name` | `github, needs, strategy, matrix, vars, inputs` | None | | `jobs.<job_id>.outputs.<output_id>` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | None | | `jobs.<job_id>.runs-on` | `github, needs, strategy, matrix, vars, inputs` | None | | `jobs.<job_id>.secrets.<secrets_id>` | `github, needs, strategy, matrix, secrets, inputs, vars` | None | | `jobs.<job_id>.services` | `github, needs, strategy, matrix, vars, inputs` | None | | `jobs.<job_id>.services.<service_id>.credentials` | `github, needs, strategy, matrix, env, vars, secrets, inputs` | None | | `jobs.<job_id>.services.<service_id>.env.<env_id>` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, inputs` | None | | `jobs.<job_id>.steps.continue-on-error` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.steps.env` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.steps.if` | `github, needs, strategy, matrix, job, runner, env, vars, steps, inputs` | `always, cancelled, success, failure, hashFiles` | | `jobs.<job_id>.steps.name` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.steps.run` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.steps.timeout-minutes` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.steps.with` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.steps.working-directory` | `github, needs, strategy, matrix, job, runner, env, vars, secrets, steps, inputs` | `hashFiles` | | `jobs.<job_id>.strategy` | `github, needs, vars, inputs` | None | | `jobs.<job_id>.timeout-minutes` | `github, needs, strategy, matrix, vars, inputs` | None | | `on.workflow_call.inputs.<inputs_id>.default` | `github, inputs, vars` | None | | `on.workflow_call.outputs.<output_id>.value` | `github, jobs, vars, inputs` | None | ### Example: printing context information to the log You can print the contents of contexts to the log for debugging. The [`toJSON` function](/actions/learn-github-actions/expressions#tojson) is required to pretty-print JSON objects to the log. {% data reusables.actions.github-context-warning %} {% raw %} ```yaml copy name: Context testing on: push jobs: dump_contexts_to_log: runs-on: ubuntu-latest steps: - name: Dump GitHub context env: GITHUB_CONTEXT: ${{ toJson(github) }} run: echo "$GITHUB_CONTEXT" - name: Dump job context env: JOB_CONTEXT: ${{ toJson(job) }} run: echo "$JOB_CONTEXT" - name: Dump steps context env: STEPS_CONTEXT: ${{ toJson(steps) }} run: echo "$STEPS_CONTEXT" - name: Dump runner context env: RUNNER_CONTEXT: ${{ toJson(runner) }} run: echo "$RUNNER_CONTEXT" - name: Dump strategy context env: STRATEGY_CONTEXT: ${{ toJson(strategy) }} run: echo "$STRATEGY_CONTEXT" - name: Dump matrix context env: MATRIX_CONTEXT: ${{ toJson(matrix) }} run: echo "$MATRIX_CONTEXT" ``` {% endraw %} ## `github` context The `github` context contains information about the workflow run and the event that triggered the run. You can also read most of the `github` context data in environment variables. For more information about environment variables, see [AUTOTITLE](/actions/learn-github-actions/variables). {% data reusables.actions.github-context-warning %} {% data reusables.actions.context-injection-warning %} | Property name | Type | Description | |---------------|------|-------------| | `github` | `object` | The top-level context available during any job or step in a workflow.

If you use the same action more than once in the same job, the name will include a suffix with the sequence number with underscore before it. 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` | `string` | The path where an action is located.

This file is unique to the current step and is a different file for each step in a job. For more information, see [AUTOTITLE](/actions/using-workflows/workflow-commands-for-github-actions#setting-an-environment-variable). | | `github.event` | `object` | The full event webhook payload. You can access individual properties of the event using this context. This object is identical to the webhook payload of the event that triggered the workflow run, and is different for each event. The webhooks for each {% data variables.product.prodname_actions %} event is linked in [AUTOTITLE](/actions/using-workflows/events-that-trigger-workflows). For example, for a workflow run triggered by the [`push` event](/actions/using-workflows/events-that-trigger-workflows#push), this object contains the contents of the [push webhook payload](/webhooks-and-events/webhooks/webhook-events-and-payloads#push). | | `github.event_name` | `string` | The name of the event that triggered the workflow run. | | `github.event_path` | `string` | The path to the file on the runner that contains the full event webhook payload. | | `github.graphql_url` | `string` | The URL of the {% data variables.product.prodname_dotcom %} GraphQL API. | | `github.head_ref` | `string` | The `head_ref` or source branch of the pull request in a workflow run.

Otherwise, the value of this property will be `null`. | | `github.path` | `string` | Path on the runner to the file that sets system `PATH` variables from workflow commands. This file is unique to the current step and is a different file for each step in a job. For more information, see [AUTOTITLE](/actions/using-workflows/workflow-commands-for-github-actions#adding-a-system-path). | | `github.ref` | `string` | {% data reusables.actions.ref-description %} | | `github.ref_name` | `string` | {% data reusables.actions.ref_name-description %} | | `github.ref_protected` | `boolean` | {% data reusables.actions.ref_protected-description %} | | `github.ref_type` | `string` | {% data reusables.actions.ref_type-description %} | | `github.repository` | `string` | The owner and repository name. For example, `octocat/Hello-World`. | | `github.repository_id` | `string` | {% data reusables.actions.repository_id-description %} | | `github.repository_owner` | `string` | The repository owner's username.

The `event` object in this example has been truncated because it is identical to the contents of the [`push` webhook payload](/webhooks-and-events/webhooks/webhook-events-and-payloads#push). {% data reusables.actions.context-example-note %} ```json { "token": "***", "job": "dump_contexts_to_log", "ref": "refs/heads/my_branch", "sha": "c27d339ee6075c1f744c5d4b200f7901aad2c369", "repository": "octocat/hello-world", "repository_owner": "octocat", "repositoryUrl": "git://github.com/octocat/hello-world.git", "run_id": "1536140711", "run_number": "314", "retention_days": "90", "run_attempt": "1", "actor": "octocat", "workflow": "Context testing", "head_ref": "", "base_ref": "", "event_name": "push", "event": { ... }, "server_url": "https://github.com", "api_url": "https://api.github.com", "graphql_url": "https://api.github.com/graphql", "ref_name": "my_branch", "ref_protected": false, "ref_type": "branch", "secret_source": "Actions", "workspace": "/home/runner/work/hello-world/hello-world", "action": "github_step", "event_path": "/home/runner/work/_temp/_github_workflow/event.json", "action_repository": "", "action_ref": "", "path": "/home/runner/work/_temp/_runner_file_commands/add_path_b037e7b5-1c88-48e2-bf78-eaaab5e02602", "env": "/home/runner/work/_temp/_runner_file_commands/set_env_b037e7b5-1c88-48e2-bf78-eaaab5e02602" } ``` ### Example usage of the `github` context This example workflow uses the `github.event_name` context to run a job only if the workflow run was triggered by the `pull_request` event. ```yaml copy name: Run CI on: [push, pull_request] jobs: normal_ci: runs-on: ubuntu-latest steps: - name: Run normal CI run: echo "Running normal CI" pull_request_ci: runs-on: ubuntu-latest if: {% raw %}${{ github.event_name == 'pull_request' }}{% endraw %} steps: - name: Run PR CI run: echo "Running PR only CI" ``` ## `env` context The `env` context contains variables that have been set in a workflow, job, or step. It does not contain variables inherited by the runner process. For more information about setting variables in your workflow, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#env). You can retrieve the values of variables stored in `env` context and use these values in your workflow file. You can use the `env` context in any key in a workflow step except for the `id` and `uses` keys. For more information on the step syntax, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idsteps). If you want to use the value of a variable inside a runner, use the runner operating system's normal method for reading environment variables. | Property name | Type | Description | |---------------|------|-------------| | `env` | `object` | This context changes for each step in a job. You can access this context from any step in a job. This object contains the properties listed below. | | `env.<env_name>` | `string` | The value of a specific environment variable. | ### Example contents of the `env` context The contents of the `env` context is a mapping of variable names to their values. The context's contents can change depending on where it is used in the workflow run. In this example, the `env` context contains two variables. ```json { "first_name": "Mona", "super_duper_var": "totally_awesome" } ``` ### Example usage of the `env` context This example workflow shows variables being set in the `env` context at the workflow, job, and step levels. The `{% raw %}${{ env.VARIABLE-NAME }}{% endraw %}` syntax is then used to retrieve variable values within individual steps in the workflow. {% data reusables.repositories.actions-env-var-note %} {% raw %} ```yaml copy name: Hi Mascot on: push env: mascot: Mona super_duper_var: totally_awesome jobs: windows_job: runs-on: windows-latest steps: - run: echo 'Hi ${{ env.mascot }}' # Hi Mona - run: echo 'Hi ${{ env.mascot }}' # Hi Octocat env: mascot: Octocat linux_job: runs-on: ubuntu-latest env: mascot: Tux steps: - run: echo 'Hi ${{ env.mascot }}' # Hi Tux ``` {% endraw %} ## `vars` context {% data reusables.actions.configuration-variables-beta-note %} The `vars` context contains custom configuration variables set at the organization, repository, and environment levels. For more information about defining configuration variables for use in multiple workflows, see [AUTOTITLE](/actions/learn-github-actions/variables#defining-variables-for-multiple-workflows). ### Example contents of the `vars` context The contents of the `vars` context is a mapping of configuration variable names to their values. ```json { "mascot": "Mona" } ``` ### Example usage of the `vars` context This example workflow shows how configuration variables set at the repository, environment, or organization levels are automatically available using the `vars` context. > [!NOTE] > Configuration variables at the environment level are automatically available after their environment is declared by the runner. {% data reusables.actions.actions-vars-context-example-usage %} ## `job` context The `job` context contains information about the currently running job. | Property name | Type | Description | |---------------|------|-------------| | `job` | `object` | This context changes for each job in a workflow run. You can access this context from any step in a job. This object contains all the properties listed below. | | `job.container` | `object` | Information about the job's container.

The runner creates the network used by all containers in a job. | | `job.services` | `object` | The service containers created for a job. For more information about service containers, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idservices). | | `job.services.<service_id>.id` | `string` | The ID of the service container. | | `job.services.<service_id>.network` | `string` | The ID of the service container network. The runner creates the network used by all containers in a job. | | `job.services.<service_id>.ports` | `object` | The exposed ports of the service container. | | `job.status` | `string` | The current status of the job. Possible values are `success`, `failure`, or `cancelled`. | ### Example contents of the `job` context This example `job` context uses a PostgreSQL service container with mapped ports. If there are no containers or service containers used in a job, the `job` context only contains the `status` property. ```json { "status": "success", "container": { "network": "github_network_53269bd575974817b43f4733536b200c" }, "services": { "postgres": { "id": "60972d9aa486605e66b0dad4abb638dc3d9116f566579e418166eedb8abb9105", "ports": { "5432": "49153" }, "network": "github_network_53269bd575974817b43f4733536b200c" } } } ``` ### Example usage of the `job` context This example workflow configures a PostgreSQL service container, and automatically maps port 5432 in the service container to a randomly chosen available port on the host. The `job` context is used to access the number of the port that was assigned on the host. ```yaml copy name: PostgreSQL Service Example on: push jobs: postgres-job: runs-on: ubuntu-latest services: postgres: image: postgres env: POSTGRES_PASSWORD: postgres options: --health-cmd pg_isready --health-interval 10s --health-timeout 5s --health-retries 5 ports: # Maps TCP port 5432 in the service container to a randomly chosen available port on the host. - 5432 steps: - run: pg_isready -h localhost -p {% raw %}${{ job.services.postgres.ports[5432] }}{% endraw %} - run: echo "Run tests against Postgres" ``` ## `jobs` context The `jobs` context is only available in reusable workflows, and can only be used to set outputs for a reusable workflow. For more information, see [AUTOTITLE](/actions/using-workflows/reusing-workflows#using-outputs-from-a-reusable-workflow). | Property name | Type | Description | |---------------|------|-------------| | `jobs` | `object` | This is only available in reusable workflows, and can only be used to set outputs for a reusable workflow.

Note how the outputs flow up from the steps, to the job, then to the `workflow_call` trigger. For more information, see [AUTOTITLE](/actions/using-workflows/reusing-workflows#using-outputs-from-a-reusable-workflow). {% raw %} ```yaml copy name: Reusable workflow on: workflow_call: # Map the workflow outputs to job outputs outputs: firstword: description: "The first output string" value: ${{ jobs.example_job.outputs.output1 }} secondword: description: "The second output string" value: ${{ jobs.example_job.outputs.output2 }} jobs: example_job: name: Generate output runs-on: ubuntu-latest # Map the job outputs to step outputs outputs: output1: ${{ steps.step1.outputs.firstword }} output2: ${{ steps.step2.outputs.secondword }} steps: - id: step1 run: echo "firstword=hello" >> $GITHUB_OUTPUT - id: step2 run: echo "secondword=world" >> $GITHUB_OUTPUT ``` {% endraw %} ## `steps` context The `steps` context contains information about the steps in the current job that have an [`id`](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsid) specified and have already run. | Property name | Type | Description | |---------------|------|-------------| | `steps` | `object` | This context changes for each step in a job. You can access this context from any step in a job. This object contains all the properties listed below. | | `steps.<step_id>.outputs` | `object` | The set of outputs defined for the step.

Possible values are `success`, `failure`, `cancelled`, or `skipped`. When a `continue-on-error` step fails, the `outcome` is `failure`, but the final `conclusion` is `success`. | | `steps.<step_id>.outcome` | `string` | The result of a completed step before [`continue-on-error`](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepscontinue-on-error) is applied. Possible values are `success`, `failure`, `cancelled`, or `skipped`. When a `continue-on-error` step fails, the `outcome` is `failure`, but the final `conclusion` is `success`. | | `steps.<step_id>.outputs.<output_name>` | `string` | The value of a specific output. | ### Example contents of the `steps` context This example `steps` context shows two previous steps that had an [`id`](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsid) specified. The first step had the `id` named `checkout`, the second `generate_number`. The `generate_number` step had an output named `random_number`. ```json { "checkout": { "outputs": {}, "outcome": "success", "conclusion": "success" }, "generate_number": { "outputs": { "random_number": "1" }, "outcome": "success", "conclusion": "success" } } ``` ### Example usage of the `steps` context This example workflow generates a random number as an output in one step, and a later step uses the `steps` context to read the value of that output. ```yaml copy name: Generate random failure on: push jobs: randomly-failing-job: runs-on: ubuntu-latest steps: - name: Generate 0 or 1 id: generate_number run: echo "random_number=$(($RANDOM % 2))" >> $GITHUB_OUTPUT - name: Pass or fail run: | if [[ {% raw %}${{ steps.generate_number.outputs.random_number }}{% endraw %} == 0 ]]; then exit 0; else exit 1; fi ``` ## `runner` context The `runner` context contains information about the runner that is executing the current job. | Property name | Type | Description | |---------------|------|-------------| | `runner` | `object` | This context changes for each job in a workflow run. This object contains all the properties listed below. | | `runner.name` | `string` | {% data reusables.actions.runner-name-description %} | | `runner.os` | `string` | {% data reusables.actions.runner-os-description %} | | `runner.arch` | `string` | {% data reusables.actions.runner-arch-description %} | | `runner.temp` | `string` | {% data reusables.actions.runner-temp-directory-description %} | | `runner.tool_cache` | `string` | {% data reusables.actions.runner-tool-cache-description %} | | `runner.debug` | `string` | {% data reusables.actions.runner-debug-description %} | | `runner.environment` | `string` | {% data reusables.actions.runner-environment-description %} | ### Example contents of the `runner` context The following example context is from a Linux {% data variables.product.prodname_dotcom %}-hosted runner. ```json { "os": "Linux", "arch": "X64", "name": "GitHub Actions 2", "tool_cache": "/opt/hostedtoolcache", "temp": "/home/runner/work/_temp" {%- comment %} # The `runner.workspace` property is purposefully not documented. It is an early Actions property that now isn't relevant for users, compared to `github.workspace`. It is kept around for compatibility. "workspace": "/home/runner/work/hello-world" {%- endcomment %} } ``` ### Example usage of the `runner` context This example workflow uses the `runner` context to set the path to the temporary directory to write logs, and if the workflow fails, it uploads those logs as artifact. ```yaml copy name: Build on: push jobs: build: runs-on: ubuntu-latest steps: - uses: {% data reusables.actions.action-checkout %} - name: Build with logs run: | mkdir {% raw %}${{ runner.temp }}{% endraw %}/build_logs echo "Logs from building" > {% raw %}${{ runner.temp }}{% endraw %}/build_logs/build.logs exit 1 - name: Upload logs on fail if: {% raw %}${{ failure() }}{% endraw %} uses: {% data reusables.actions.action-upload-artifact %} with: name: Build failure logs path: {% raw %}${{ runner.temp }}{% endraw %}/build_logs ``` ## `secrets` context The `secrets` context contains the names and values of secrets that are available to a workflow run. The `secrets` context is not available for composite actions due to security reasons. If you want to pass a secret to a composite action, you need to do it explicitly as an input. For more information about secrets, see [AUTOTITLE](/actions/security-guides/using-secrets-in-github-actions). `GITHUB_TOKEN` is a secret that is automatically created for every workflow run, and is always included in the `secrets` context. For more information, see [AUTOTITLE](/actions/security-guides/automatic-token-authentication). {% data reusables.actions.secrets-redaction-warning %} | Property name | Type | Description | |---------------|------|-------------| | `secrets` | `object` | This context is the same for each job in a workflow run. You can access this context from any step in a job. This object contains all the properties listed below. | | `secrets.GITHUB_TOKEN` | `string` | Automatically created token for each workflow run. For more information, see [AUTOTITLE](/actions/security-guides/automatic-token-authentication). | | `secrets.<secret_name>` | `string` | The value of a specific secret. | ### Example contents of the `secrets` context The following example contents of the `secrets` context shows the automatic `GITHUB_TOKEN`, as well as two other secrets available to the workflow run. ```json { "github_token": "***", "NPM_TOKEN": "***", "SUPERSECRET": "***" } ``` ### Example usage of the `secrets` context {% data reusables.actions.github_token-input-example %} ## `strategy` context For workflows with a matrix, the `strategy` context contains information about the matrix execution strategy for the current job. | Property name | Type | Description | |---------------|------|-------------| | `strategy` | `object` | This context changes for each job in a workflow run. You can access this context from any job or step in a workflow. This object contains all the properties listed below. | | `strategy.fail-fast` | `boolean` | When this evaluates to `true`, all in-progress jobs are canceled if any job in a matrix fails. For more information, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstrategyfail-fast). | | `strategy.job-index` | `number` | The index of the current job in the matrix. **Note:** This number is a zero-based number. The first job's index in the matrix is `0`. | | `strategy.job-total` | `number` | The total number of jobs in the matrix. **Note:** This number **is not** a zero-based number. For example, for a matrix with four jobs, the value of `job-total` is `4`. | | `strategy.max-parallel` | `number` | The maximum number of jobs that can run simultaneously when using a `matrix` job strategy. For more information, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstrategymax-parallel). | ### Example contents of the `strategy` context The following example contents of the `strategy` context is from a matrix with four jobs, and is taken from the final job. Note the difference between the zero-based `job-index` number, and `job-total` which is not zero-based. ```json { "fail-fast": true, "job-index": 3, "job-total": 4, "max-parallel": 4 } ``` ### Example usage of the `strategy` context This example workflow uses the `strategy.job-index` property to set a unique name for a log file for each job in a matrix. ```yaml copy name: Test strategy on: push jobs: test: runs-on: ubuntu-latest strategy: matrix: test-group: [1, 2] node: [14, 16] steps: - run: echo "Mock test logs" > test-job-{% raw %}${{ strategy.job-index }}{% endraw %}.txt - name: Upload logs uses: {% data reusables.actions.action-upload-artifact %} with: name: Build log for job {% raw %}${{ strategy.job-index }}{% endraw %} path: test-job-{% raw %}${{ strategy.job-index }}{% endraw %}.txt ``` ## `matrix` context For workflows with a matrix, the `matrix` context contains the matrix properties defined in the workflow file that apply to the current job. For example, if you configure a matrix with the `os` and `node` keys, the `matrix` context object includes the `os` and `node` properties with the values that are being used for the current job. There are no standard properties in the `matrix` context, only those which are defined in the workflow file. | Property name | Type | Description | |---------------|------|-------------| | `matrix` | `object` | This context is only available for jobs in a matrix, and changes for each job in a workflow run. You can access this context from any job or step in a workflow. This object contains the properties listed below. | | `matrix.<property_name>` | `string` | The value of a matrix property. | ### Example contents of the `matrix` context The following example contents of the `matrix` context is from a job in a matrix that has the `os` and `node` matrix properties defined in the workflow. The job is executing the matrix combination of an `ubuntu-latest` OS and Node.js version `16`. ```json { "os": "ubuntu-latest", "node": 16 } ``` ### Example usage of the `matrix` context This example workflow creates a matrix with `os` and `node` keys. It uses the `matrix.os` property to set the runner type for each job, and uses the `matrix.node` property to set the Node.js version for each job. ```yaml copy name: Test matrix on: push jobs: build: runs-on: {% raw %}${{ matrix.os }}{% endraw %} strategy: matrix: os: [ubuntu-latest, windows-latest] node: [14, 16] steps: - uses: {% data reusables.actions.action-setup-node %} with: node-version: {% raw %}${{ matrix.node }}{% endraw %} - name: Output node version run: node --version ``` ## `needs` context The `needs` context contains outputs from all jobs that are defined as a direct dependency of the current job. Note that this doesn't include implicitly dependent jobs (for example, dependent jobs of a dependent job). For more information on defining job dependencies, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idneeds). | Property name | Type | Description | |---------------|------|-------------| | `needs` | `object` | This context is only populated for workflow runs that have dependent jobs, and changes for each job in a workflow run. You can access this context from any job or step in a workflow. This object contains all the properties listed below. | | `needs.<job_id>` | `object` | A single job that the current job depends on. | | `needs.<job_id>.outputs` | `object` | The set of outputs of a job that the current job depends on. | | `needs.<job_id>.outputs.<output name>` | `string` | The value of a specific output for a job that the current job depends on. | | `needs.<job_id>.result` | `string` | The result of a job that the current job depends on. Possible values are `success`, `failure`, `cancelled`, or `skipped`. | ### Example contents of the `needs` context The following example contents of the `needs` context shows information for two jobs that the current job depends on. ```json { "build": { "result": "success", "outputs": { "build_id": "123456" } }, "deploy": { "result": "failure", "outputs": {} } } ``` ### Example usage of the `needs` context This example workflow has three jobs: a `build` job that does a build, a `deploy` job that requires the `build` job, and a `debug` job that requires both the `build` and `deploy` jobs and runs only if there is a failure in the workflow. The `deploy` job also uses the `needs` context to access an output from the `build` job. ```yaml copy name: Build and deploy on: push jobs: build: runs-on: ubuntu-latest outputs: build_id: {% raw %}${{ steps.build_step.outputs.build_id }}{% endraw %} steps: - name: Build id: build_step run: echo "build_id=$RANDOM" >> $GITHUB_OUTPUT deploy: needs: build runs-on: ubuntu-latest steps: - run: echo "Deploying build {% raw %}${{ needs.build.outputs.build_id }}{% endraw %}" debug: needs: [build, deploy] runs-on: ubuntu-latest if: {% raw %}${{ failure() }}{% endraw %} steps: - run: echo "Failed to build and deploy" ``` ## `inputs` context The `inputs` context contains input properties passed to an action, to a reusable workflow, or to a manually triggered workflow. For reusable workflows, the input names and types are defined in the [`workflow_call` event configuration](/actions/using-workflows/events-that-trigger-workflows#workflow-reuse-events) of a reusable workflow, and the input values are passed from [`jobs.<job_id>.with`](/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idwith) in an external workflow that calls the reusable workflow. For manually triggered workflows, the inputs are defined in the [`workflow_dispatch` event configuration](/actions/using-workflows/events-that-trigger-workflows#workflow_dispatch) of a workflow. The properties in the `inputs` context are defined in the workflow file. They are only available in a [reusable workflow](/actions/using-workflows/reusing-workflows) or in a workflow triggered by the [`workflow_dispatch` event](/actions/using-workflows/events-that-trigger-workflows#workflow_dispatch) | Property name | Type | Description | |---------------|------|-------------| | `inputs` | `object` | This context is only available in a [reusable workflow](/actions/using-workflows/reusing-workflows) or in a workflow triggered by the [`workflow_dispatch` event](/actions/using-workflows/events-that-trigger-workflows#workflow_dispatch). You can access this context from any job or step in a workflow. This object contains the properties listed below. | | `inputs.<name>` | `string` or `number` or `boolean` or `choice` | Each input value passed from an external workflow. | ### Example contents of the `inputs` context The following example contents of the `inputs` context is from a workflow that has defined the `build_id`, `deploy_target`, and `perform_deploy` inputs. ```json { "build_id": 123456768, "deploy_target": "deployment_sys_1a", "perform_deploy": true } ``` ### Example usage of the `inputs` context in a reusable workflow This example reusable workflow uses the `inputs` context to get the values of the `build_id`, `deploy_target`, and `perform_deploy` inputs that were passed to the reusable workflow from the caller workflow. {% raw %} ```yaml copy name: Reusable deploy workflow on: workflow_call: inputs: build_id: required: true type: number deploy_target: required: true type: string perform_deploy: required: true type: boolean jobs: deploy: runs-on: ubuntu-latest if: ${{ inputs.perform_deploy }} steps: - name: Deploy build to target run: echo "Deploying build:${{ inputs.build_id }} to target:${{ inputs.deploy_target }}" ``` {% endraw %} ### Example usage of the `inputs` context in a manually triggered workflow This example workflow triggered by a `workflow_dispatch` event uses the `inputs` context to get the values of the `build_id`, `deploy_target`, and `perform_deploy` inputs that were passed to the workflow. {% raw %} ```yaml copy on: workflow_dispatch: inputs: build_id: required: true type: string deploy_target: required: true type: string perform_deploy: required: true type: boolean jobs: deploy: runs-on: ubuntu-latest if: ${{ inputs.perform_deploy }} steps: - name: Deploy build to target run: echo "Deploying build:${{ inputs.build_id }} to target:${{ inputs.deploy_target }}" ``` {% endraw %}
