Github Actions

Integrate Terrakube with GitHub Actions is easy and you can handle your workspace from GitHub.

The GIT repository will represent a Terrakube Organization and each folder inside the repository will be a new workspace.

There is an example available in the following link

Configuration

Add the following snippet to the script section of your github actions file:

Pull Request example

To run a terraform plan using Terrakube templates use the following example:

File: .github/workflows/pull_request.yml

name: Terrakube Plan

on:
  pull_request:
    types: [opened, synchronize, reopened]

jobs:
  build:
    runs-on: ubuntu-latest
    name: "Running Terrakube Plan"
    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - uses: AzBuilder/terrakube-action-github@main
        with:
          TERRAKUBE_TOKEN:  ${{ secrets.TERRAKUBE_PAT }} 
          TERRAKUBE_TEMPLATE: "Terraform-Plan"
          TERRAKUBE_ENDPOINT: ${{ secrets.TERRAKUBE_ENDPOINT }}  
          TERRAKUBE_BRANCH: ${{ github.head_ref }}
          TERRAKUBE_ORGANIZATION: "terrakube_organization_name"
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          SHOW_OUTPUT: true

A new workspace will be created for each folder with the file "terrakube.json". For each PR only new folders or folders that has been updated will be evaluated inside Terrakube.

Push Main branch

To run a terraform apply using Terrakube templates use the following example:

File: .github/workflows/push_main.yml

name: Terrakube Apply

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    name: "Running Terrakube Apply"
    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - uses: AzBuilder/terrakube-action-github@main
        with:
          TERRAKUBE_TOKEN:  ${{ secrets.TERRAKUBE_PAT }} 
          TERRAKUBE_TEMPLATE: "Terraform-Plan/Apply"
          TERRAKUBE_ENDPOINT: ${{ secrets.TERRAKUBE_GITPOD }}  
          TERRAKUBE_BRANCH: "main"
          TERRAKUBE_ORGANIZATION: "terrakube_organization_name"
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          SHOW_OUTPUT: false

Terrakube Variables

To define terrakube variables to connect to cloud providers it is recommended to use Global Variables inside the organization using the UI. Terraform variables could be define inside a terraform.tfvars inside each folder or you can define inside the Terrakube UI after the workspace creation.

GitHub Action Inputs

(*) = required variable.

Terraform Version Configuration

Create a file called "terrakube.json" and include the terraform version that will be used for the job execution

{
	"terraform": "1.2.9"
}

Build GitHub Action

To build the github action in your local machine use the following.

git clone https://github.com/AzBuilder/terrakube-action-github.git
yarn install
yarn build
