Important
You probably don't need to install this custom action.
Instead, use the native concurrency property to cancel workflows, for example:
concurrency:
group: ${{ github.workflow }}-${{ github.ref }}
cancel-in-progress: ${{ github.ref != 'refs/heads/main' }}
Read GitHub's official documentation to learn more.
This is a GitHub Action that will cancel any previous runs that are not completed for a given workflow.
This includes runs with a status of queued or in_progress.
When you git push, this GitHub Action will capture the current Branch and SHA. It will query GitHub's API to find previous workflow runs that match the Branch but do not match the SHA. These in-progress runs will be canceled leaving only this run, or the latest run.
Read more about the Workflow Runs API.
Typically, you will want to add this action as the first step in a workflow so it can cancel itself on the next push.

runs-on: ubuntu-latest
steps:
- name: Cancel Previous Runs
uses: styfle/cancel-workflow-action
#- name: Run Tests
# uses: actions/setup-node
# run: node test.js
# ... etcIt is recommended to pin a specific version of this action so you don't automatically upgrade to the latest which could introduce breaking changes.

Visit Releases to find the latest version at the top of the page.
Warning
You might run into "the `uses' attribute must be a path, a Docker image, or owner/repo@ref" error if you don't specify a version.
In some cases, you may wish to avoid modifying all your workflows and instead create a new workflow that cancels your other workflows. This can be useful when you have a problem with workflows getting queued.
- Visit
https://api.github.com/repos/:org/:repo/actions/workflowsto find the Workflow ID(s) you wish to automaticaly cancel. - Add a new file
.github/workflows/cancel.ymlwith the following:
name: Cancel
on: [push]
jobs:
cancel:
name: 'Cancel Previous Runs'
runs-on: ubuntu-latest
timeout-minutes: 3
steps:
- uses: styfle/cancel-workflow-action
with:
workflow_id: 479426- Note:
workflow_idcan be a Workflow ID (number) or Workflow File Name (string) - Note:
workflow_idalso accepts a comma separated list if you need to cancel multiple workflows - Note:
workflow_idaccepts the valueall, which will cancel all the workflows running in the branch
The default GitHub token access is unable to cancel workflows for pull_request
when a pull request is opened from a fork. Therefore, a special setup using
workflow_run, which also works for push, is needed.
Create a .github/workflows/cancel.yml with the following instead and replace
"CI" with the workflow name that contains the pull_request workflow:
name: Cancel
on:
workflow_run:
workflows: ["CI"]
types:
- requested
jobs:
cancel:
runs-on: ubuntu-latest
steps:
- uses: styfle/cancel-workflow-action
with:
workflow_id: ${{ github.event.workflow.id }}In some cases, you may wish to cancel workflows when you close a Pull Request. Because this is not a push event, the SHA will be the same, so you must use the ignore_sha option.
on:
pull_request:
types: [closed]
jobs:
cleanup:
name: 'Cleanup After PR Closed'
runs-on: ubuntu-latest
timeout-minutes: 3
steps:
- name: Cancel build runs
uses: styfle/cancel-workflow-action
with:
ignore_sha: true
workflow_id: 479426Because this action can only cancel workflows if it is actually being run, it only helps if the pipeline isn't saturated and there are still runners available to schedule the workflow.
By default, this action does not cancel any workflows created after itself. The all_but_latest flags allows the action to cancel itself and all later-scheduled workflows, leaving only the latest.

with:
all_but_latest: trueSome workflows may be dangerous to cancel when they are in progress. If you want to play safe and cancel only workflows that are in state waiting, most likely waiting for approval to be deployed in a protected environment, use only_status to only cancel runs with a specific status.
name: Cancel

only_status: 'waiting'No change to permissions is required by default. The instructions below are for improved control over of those permissions.
By default, GitHub creates the GITHUB_TOKEN for Actions with some read/write permissions. It may be a good practice to switch to read-only permissions by default. Visit the dedicated documentation page for details.
Permissions can be set for all Jobs in a Workflow or a specific Job, see the reference manual page. cancel-workflow-action only requires write access to the actions scope, so it is enough to have:
jobs:
test:
runs-on: ubuntu-latest
permissions:
actions: write
steps:
- name: Cancel Previous Runs
uses: styfle/cancel-workflow-action
with:
access_token: ${{ github.token }}Note : This is typical when global access is set to be restrictive. Only this job will elevate those permissions.
