Snyk GitHub Actions

A set of GitHub Action for using Snyk to check for vulnerabilities in your GitHub projects. A different action is required depending on which language or build tool you are using. We currently support:

• CocoaPods
• dotNET
• Golang
• Gradle
• Gradle-jdk11
• Gradle-jdk12
• Gradle-jdk14
• Gradle-jdk16
• Gradle-jdk17
• Maven
• Maven-3-jdk-11
• Node
• PHP
• Python
• Python-3.6
• Python-3.7
• Python-3.8
• Python-3.9
• Python-3.10
• Ruby
• Scala
• Docker
• Infrastructure as Code
• Setup

Here's an example of using one of the Actions, in this case to test a Node.js project:

name: Example workflow using Snyk
on: push
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - name: Run Snyk to check for vulnerabilities
        uses: snyk/actions/node@master
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}

If you want to send data to Snyk, and be alerted when new vulnerabilities are discovered, you can run Snyk monitor like so:

name: Example workflow using Snyk
on: push
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - name: Run Snyk to check for vulnerabilities
        uses: snyk/actions/node@master
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
        with:
          command: monitor

See the individual Actions linked above for per-language instructions.

Note that GitHub Actions will not pass on secrets set in the repository to forks being used in pull requests, and so the Snyk actions that require the token will fail to run.

Bring your own development environment

The per-language Actions automatically install all the required development tools for Snyk to determine the correct dependencies and hence vulnerabilities from different language environments. If you have a workflow where you already have those installed then you can instead use the snyk/actions/setup Action to just install Snyk CLI:

name: Snyk example
on: push
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - uses: snyk/actions/setup@master
      - uses: actions/setup-go@v1
        with:
          go-version: '1.13'
      - name: Snyk monitor
        run: snyk test
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}

The example here uses actions/setup-go would you would need to select the right actions to install the relevant development requirements for your project. If you are already using the same pipeline to build and test your application you're likely already doing so.

Getting your Snyk token

The Actions example above refer to a Snyk API token:

env:
  SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}

Every Snyk account has this token. Once you create an account you can find it in one of two ways:

1. In the UI, go to your Snyk account's settings page and retrieve the API token, as shown in the following Revoking and regenerating Snyk API tokens.
2. If you're using the Snyk CLI locally you can retrieve it by running snyk config get api.

GitHub Code Scanning support

All Snyk GitHub Actions support integration with GitHub Code Scanning to show vulnerability information in the GitHub Security tab. You can see full details on the individual action READMEs linked above.

Continuing on error

The above examples will fail the workflow when issues are found. If you want to ensure the Action continues, even if Snyk finds vulnerabilities, then continue-on-error can be used..

name: Example workflow using Snyk with continue on error
on: push
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - name: Run Snyk to check for vulnerabilities
        uses: snyk/actions/node@master
        continue-on-error: true
        env:
          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
