name: Clean up relay preview

# Tears down stage `pr-<n>` when `relay:preview` is removed or the PR closes,
# and sweeps stages left behind by a failed teardown.
#
# This runs under pull_request_target, so the workflow and the Alchemy program
# come from the default branch. No PR code runs here, which is why it needs no
# reviewer approval and why a PR cannot edit its own teardown to reach secrets.

For more information about what information is available in the event context, see Using event information. For more information about how to use conditionals, see Evaluate expressions in workflows and actions.

### Using environments to manually trigger workflow jobs

If you want to manually trigger a specific job in a workflow, you can use an environment that requires approval from a specific team or user. First, configure an environment with required reviewers. For more information, see Managing environments for deployment. Then, reference the environment name in a job in your workflow using the `environment:` key. Any job referencing the environment will not run until at least one reviewer approves the job.

For example, the following workflow will run whenever there is a push to main. The `build` job will always run. The `publish` job will only run after the `build` job successfully completes (due to `needs: [build]`) and after all of the rules (including required reviewers) for the environment called `production` pass (due to `environment: production`).
    
    `on:
      push:
        branches:
          - main
    
    jobs:
      build:
        runs-on: ubuntu-latest
        steps:
          - name: build
            run: |
              echo &#39;building&#39;
    
      publish:
        needs: [build]
        runs-on: ubuntu-latest
        environment: production
        steps:
          - name: publish
            run: |
              echo &#39;publishing&#39;
    `

Note

Environments, environment secrets, and deployment protection rules are available in public repositories for all current GitHub plans. They are not available on legacy plans, such as Bronze, Silver, or Gold. For access to environments, environment secrets, and deployment branches in private or internal repositories, you must use GitHub Pro, GitHub Team, or GitHub Enterprise. If you are on a GitHub Free, GitHub Pro, or GitHub Team plan, other deployment protection rules, such as a wait timer or required reviewers, are only available for public repositories.

<title>Securely using pull_request_target - GitHub Docs</title>
<location>https://docs.github.com/en/actions/reference/security/securely-using-pull_request_target</location>
<excerpt>citeturn0search3 [wordlim: 200] Crawled: last week; The `pull_request` event (along with `pull_request_review` and `pull_request_review_comment`) is unusual: it runs the workflow file from the merge commit of the pull request. ... For example, an `issue_comment` or `workflow_run` workflow that fetches and runs a fork&#39;s pull request code is vulnerable in the same way. ... Workflows triggered by this event should not check out, build, or run code from an untrusted pull request with access to repository secrets or a privileged `GITHUB_TOKEN`. ... If self-hosted runners are used, you must confirm that the runner environment is properly restricted from internal resources and is not reused across GitHub Actions runs.

To understand why this is safe by default, and how that safety is commonly broken, review `pull_request_target` against `pull_request`.

The `pull_request` event (along with `pull_request_review` and `pull_request_review_comment`) is unusual: it runs the workflow file from the merge commit of the pull request. For a pull request opened from a fork, that commit is controlled by someone without write access to the base repository. To run untrusted workflow code safely, GitHub restricts these events to a read-only `GITHUB_TOKEN`, withholds access to other secrets, and applies fork approval policies to prevent compute abuse. By default, `actions/checkout` in a `pull_request` workflow also checks out the pull request&#39;s merge commit, so the code checked out and the workflow that runs are consistent.

`pull_request_target` makes one critical and subtle change: the workflow, and any subsequent `actions/checkout` call that does not specify a `ref`, is taken from the base repository&#39;s default branch, not from the pull request. 
While the policy is in evaluate mode, review your policy insights to identify workflows that use `pull_request_target` and would be blocked when the policy is enforced.

For each affected workflow, decide whether `pull_request_target` is still required:

  * If the workflow does not need `pull_request_target`, update it to use a safer event where appropriate, such as `pull_request`.
  * If the workflow must continue to use `pull_request_target`, create or update an applicable Actions event policy that explicitly allows `pull_request_target`.
  * If you do not want to allow `pull_request_target`, leave the default policy in place. After enforcement, GitHub will block workflows triggered by that event.

Warning

Only allow `pull_request_target` when it is necessary. Workflows triggered by this event should not check out, build, or run code from an untrusted pull request with access to repository secrets or a privileged `GITHUB_TOKEN`.

For more information about configuring event policies and viewing insights, see Governing execution of GitHub Actions workflows. To manage policies programmatically, see REST API endpoints for GitHub Actions policies.

## Deciding whether to use `pull_request_target`

Some workflows need to check out fork pull request code with elevated trust, and this is why `pull_request_target` was created in the first place. For example, generating coverage reports that require a private artifact registry or producing and running authenticated checks against the changes introduced from the pull request. Consider the questions below before using `pull_request_target` or opting into the `allow-unsafe-pr-checkout` flag in `actions/checkout`.

  * Can you use `pull_request` instead? `pull_request` triggers on the same events as `pull_request_target` and runs the workflow code from the `pull_request` merge branch. It does this safely on pull requests from forks with the protections detailed above. If additional secret access is not needed, use `pull_request`. More complex workflows can be restructured to separate potentially dangerous handling of pull request code from accessing secrets. For more information, see Preventing pwn requests from the GitHub Security Lab.

<excerpt>citeturn0search1 [wordlim: 200] Crawled: today; When a workflow is triggered by the `pull_request_target` event, the `GITHUB_TOKEN` is granted read/write repository permission, even when it is triggered from a public fork. ... For example, `pull-requests: write` permits an action to add a label to a pull request. ... For more information, see Repository permissions for &quot;Secret scanning alerts&quot; in &quot;Permissions required for GitHub Apps.&quot; ... The permissions are then adjusted based on any configuration within the workflow file, first at the workflow level and then at the job level. ... Instead, consider setting secrets as job-level environment variables, then referencing the environment variables to conditionally run steps in the job. ... /.github/actions/my-private-repo/my-action ... For more information, see Making authenticated API requests with a GitHub App in a GitHub Actions workflow.
For more information, see Permissions required for GitHub Apps.
`pull-requests`  | Work with pull requests. For example, `pull-requests: write` permits an action to add a label to a pull request. For more information, see Permissions required for GitHub Apps.
`security-events`  | Work with GitHub code scanning alerts. For example, `security-events: read` permits an action to list the code scanning alerts for the repository, and `security-events: write` allows an action to update the status of a code scanning alert. For more information, see Repository permissions for &quot;Code scanning alerts&quot;.
For Dependabot alerts, use the `vulnerability-alerts` permission. Secret scanning alerts cannot be read with this permission and require a GitHub App or a personal access token. For more information, see Repository permissions for &quot;Secret scanning alerts&quot; in &quot;Permissions required for GitHub Apps.&quot;
`statuses`  | Work with commit statuses. For example, `statuses:read` permits an action to list the commit statuses for a given reference. For more information, see Permissions required for GitHub Apps.
`vulnerability-alerts`  | Read Dependabot alerts. For example, `vulnerability-alerts: read` permits an action to list Dependabot alerts for the repository. Only `read` and `none` are supported; `write` is not valid. When `write-all` or `read-all` is used, `vulnerability-alerts` is automatically included as `read`. For more information, see Repository permissions for &quot;Dependabot alerts&quot;.

    
    `steps:
      - name: My first step
        if: ${{ github.event_name == &#39;pull_request&#39; &amp;&amp; github.event.action == &#39;unassigned&#39; }}
        run: echo This event is a pull request that had an assignee removed.
    `

### Example: Using status check functions

The `my backup step` only runs when the previous step of a job fails. For more information, see Evaluate expressions in workflows and actions.
    
    `steps:
      - name: My first step
        uses: octo-org/action-name@main
      - name: My backup step
        if: ${{ failure() }}
        uses: actions/heroku@1.0.0
    `

### Example: Using secrets

Secrets cannot be directly referenced in `if:` conditionals. Instead, consider setting secrets as job-level environment variables, then referencing the environment variables to conditionally run steps in the job.

If a secret has not been set, the return value of an expression referencing the secret (such as `${{ secrets.SuperSecret }}` in the example) will be an empty string.
    
    `name: Run a step if a secret has been set
    on: push
    jobs:
      my-jobname:
        runs-on: ubuntu-latest
        env:
          super_secret: ${{ secrets.SuperSecret }}
        steps:
          - if: ${{ env.super_secret != &#39;&#39; }}
            run: echo &#39;This step will only run if the secret has a value set.&#39;
          - if: ${{ env.super_secret == &#39;&#39; }}

<excerpt>citeturn0search2 [wordlim: 200] Crawled: last week; For private repositories, the Access policy on the Actions settings page of the called workflow&#39;s repository must be explicitly configured to allow access from repositories containing caller workflows - see Managing GitHub Actions settings for a repository. ... This means that when the owner, name of an action&#39;s repository, or name of an action is changed, any workflows using that action with the previous name will fail. ...   * You can call a maximum of 50 unique reusable workflows from a single workflow file. ...   * Any environment variables set in an `env` context defined at the workflow level in the caller workflow are not propagated to the called workflow. ...   * `jobs.&lt;job_id&gt;.secrets.&lt;secret_id&gt;` ... `GITHUB_TOKEN` permissions can only be the same or more restrictive in nested workflows.

# Reusing workflow configurations

Find information about avoiding duplication when creating a workflow by reusing existing workflows and using YAML anchors and aliases.

## Reusable workflows

This article provides reference information for reusable workflows and workflow templates, including access rules, limitations, supported keywords, and runner behavior.

You can centralize deterministic, repeatable logic in reusable workflows, and use agentic workflows for tasks that require contextual judgment about your repository&#39;s content such as analysis, summaries, and recommendations. For more information, see Creating GitHub Agentic Workflows.

### Access to reusable workflows

A reusable workflow can be used by another workflow if any of the following is true:

  * Both workflows are in the same repository.
  * The called workflow is stored in a public repository, and your organization allows you to use public reusable workflows.
  * The called workflow is stored in a private repository and the settings for that repository allow it to be accessed. 
  * To reuse variables in multiple workflows, set them at the organization, repository, or environment levels and reference them using the `vars` context. For more information, see Store information in variables and Contexts reference.

  * Reusable workflows are called directly within a job, and not from within a job step. You cannot, therefore, use `GITHUB_ENV` to pass values to job steps in the caller workflow.

### Supported keywords for jobs that call a reusable workflow

When you call a reusable workflow, you can only use the following keywords in the job containing the call:

  * `jobs.&lt;job_id&gt;.name`

  * `jobs.&lt;job_id&gt;.uses`

  * `jobs.&lt;job_id&gt;.with`

  * `jobs.&lt;job_id&gt;.with.&lt;input_id&gt;`

  * `jobs.&lt;job_id&gt;.secrets`

  * `jobs.&lt;job_id&gt;.secrets.&lt;secret_id&gt;`

  * `jobs.&lt;job_id&gt;.secrets.inherit`

  * `jobs.&lt;job_id&gt;.strategy`

  * `jobs.&lt;job_id&gt;.needs`

  * `jobs.&lt;job_id&gt;.if`

Selects an action to run as part of a step in your job. An action is a reusable unit of code. You can use an action defined in the same repository as the workflow, a public repository, or in a published Docker container image.

We strongly recommend that you include the version of the action you are using by specifying a Git ref, SHA, or Docker tag. </excerpt>

Keep PR-editable workflows away from repository deployment secrets.

This workflow checks out and runs the pull request's code. If a same-repository contributor can edit the workflow, they can remove environment: relay-preview and bypass the required approval while retaining access to the documented repository-scoped Cloudflare, PlanetScale, and Axiom secrets. The fork check does not prevent this path.

Move the credentials used by this job to relay-preview environment secrets, and retain the environment gate.

Move the Cloudflare, PlanetScale, and Axiom credentials used by the
relay-preview job from repository secrets to the relay-preview environment’s
secrets, and keep the job bound to the relay-preview environment so its approval
gate remains in effect.

Delete stage-owned CNAMEs after their tunnel is gone.

ManagedEndpointProvider.release can delete a tunnel without deleting its DNS record. The sweep then excludes that orphan because its tunnel ID is absent from tunnelIds, so it can persist across later runs.

Keep the exact stage-specific record-name check. Replace the live-tunnel-ID requirement with validation that the CNAME target is a valid *.cfargotunnel.com target. Do not match the target suffix alone, because the record name is required to establish stage ownership.

Update the CNAME filter around isPreviewTunnelRecordName to keep its exact
stage-specific record-name check while replacing the tunnelIds membership check
with validation that record.content is a valid *.cfargotunnel.com target; do not
use the target suffix alone to determine stage ownership.
