Build and Test

setup-kubeconform

A GitHub Action that sets up the commandline-based Kubernetes manifest validation tool Kubeconform. The tool will be downloaded from the Kubeconform releases page, installed, and added to the PATH environment variable automatically. All operating systems and architectures are supported for released artifacts.

NOTE: Instead of using this action, you may want to run Kubeconform in a container. Refer to the documentation for more information.

Using the Action

It's recommended to use the action as a single setup step. Subsequent steps can directly call the executable. There are no limitation to the options that can be provided to the kubeconform command. The following example shows its usage.

name: Validate Kubernetes manifests
on: [push, pull_request]
jobs:
  kubeconform:
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
    runs-on: ${{ matrix.os }}
    steps:
    - uses: actions/checkout@v4

    - name: Set up Kubeconform
      uses: bmuschko/setup-kubeconform@v1
    
    - name: Validate manifests
      run: kubeconform -summary -verbose .

See the Kubeconform usage page for more information on available flags, or run kubeconform --help to render the list of flags in the console to craft your command.

Action Inputs and Outputs

The action defines inputs and outputs. The inputs let you drive the runtime behavior of the action. The outputs retrieve values populated after executing the action.

Inputs

Parameter Required Default Value Description
kubeconform-version false 0.6.3 The version of the Kubeconform to be installed. The provided string should not include the prefix v.

Outputs

Parameter Description
installation-path The installation path of Kubeconform, empty if it couldn't be installed.

Example

The following example shows the use of both inputs and outputs. Here, the default version of Kubeconform has been switched to 0.6.1. The workflow adds a step that renders the installation path after the Kubeconform executable has been installed.

jobs:
  kubeconform:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4

    - name: Set up Kubeconform
      id: setup-kubeconform
      uses: bmuschko/setup-kubeconform@v1
      with:
        kubeconform-version: '0.6.1'

    - name: Print Kubeconform installation path
      env:
        KUBECONFORM_INSTALLATION_PATH: ${{ steps.setup-kubeconform.outputs.installation-path }}
      run: |
          echo "Kubeconform installed..."
          echo "Installation path: ${KUBECONFORM_INSTALLATION_PATH}"
      shell: bash
