Overview

The Datree CLI provides a policy enforcement solution to run automatic checks for rule violations in Kuberenetes configuration files.
This action runs the Datree CLI against given k8s configuration file/s in your repository, featuring full Helm and Kustomize support.
To learn more about Datree, visit the datree website.

Setup

Get started in 2 simple steps:

Obtain your Datree account token by following the instructions described here.
Configure your token by setting DATREE_TOKEN as a secret or environment variable (see "Examples" section of this readme).

Usage

In your workflow, set this action as a step. For example:

- name: Run Datree Policy Check
  uses: datreeio/action-datree@main
  with:
    path: 'someDirectory/someFile.yaml'
    cliArguments: '--schema-version 1.20.0'

Input	Required	Description
path	Yes	A path to the file/s you wish to run your Datree test against. This can be a single file or a Glob pattern signifying a directory.
cliArguments	No	The desired Datree CLI arguments for the policy check. In the above example, schema version 1.20.0 will be used.
isHelmChart	No	Specify whether the given path is a Helm chart. If this option is unused, the path will be considered as a regular yaml file. When `isHelmChart` is set, it will perform a recursive test for all helm charts inside the given path.
helmArguments	No	The Helm arguments to be used, if the path is a Helm chart.
isKustomization	No	Specify whether the given path is a directory containing a "kustomization.yaml" file. If this option is unused, the path will be considered as a regular yaml file.
kustomizeArguments	No	The Kustomize arguments to be used, if the path is a Kustomization directory.

For more information and examples of using this action with Helm/Kustomize, see below

Examples

Here is an example workflow that uses this action to run a Datree policy check on all of the k8s manifest files under the current directory, on every push/pull request:

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]
    
env:
  DATREE_TOKEN: ${{ secrets.DATREE_TOKEN }} 

jobs:
  k8sPolicyCheck:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout
        uses: actions/checkout@v2
        
      - name: Run Datree Policy Check
        uses: datreeio/action-datree@main
        with:
          path: '**/*.yaml'
          cliArguments: '--only-k8s-files'

Here is another example that runs a policy check on a single file in the root of the repository on every push, using a policy named "Staging". The output will be in simple text, with no colors or emojis:

on:
  push:
    branches: [ main ]
    
env:
  DATREE_TOKEN: ${{ secrets.DATREE_TOKEN }} 

jobs:
  k8sPolicyCheck:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout
        uses: actions/checkout@v2
        
      - name: Run Datree Policy Check
        uses: datreeio/action-datree@main
        with:
          path: 'file.yaml'
          cliArguments: '--policy Staging --output simple'

Using Helm

This action enables performing policy checks on Helm charts, by utilizing the Datree Helm plugin.
To test a Helm chart, simply set the "isHelmChart" parameter to "true", and add any Helm arguments you wish to use to the "helmArguments" parameter, like so:

- name: Run Datree Policy Check
        uses: datreeio/action-datree@main
        with:
          path: 'myChartDirectory'
          cliArguments: ''
          isHelmChart: true
          helmArguments: '--values values.yaml'

Using Kustomize

This action utilizes the Datree CLI's built-in Kustomize support. To use the plugin to test a kustomization, set "isKustomization" to 'true', and add any Kustomize arguments you wish to use to the "kustomizeArguments" setting, like so:

- name: Run Datree Policy Check
        uses: datreeio/action-datree@main
        with:
          path: 'my/kustomization/directory'
          isKustomization: true
          kustomizeArguments:

Github Code Scanning (SARIF)

You can upload your policy check results to Github's code scanning to be displayed as security alerts by doing the following:

Set -o sarif in the CLI arguments of this action (this will automatically create a file named datree.sarif containing your test results)
Upload the SARIF file to Github by adding the following step to your workflow:

- name: Upload analysis results to GitHub
  uses: github/codeql-action/upload-sarif@v2
  with:
    sarif_file: datree.sarif
    wait-for-processing: true

Output

The result of your policy checks will look like this:

In addition to Datree's standard output, Github's job summary feature is now supported 📝
