Terraform Apply GitHub Actions Only on Main Push: Streamlining Your Infrastructure Automation
In today’s fast-paced development environment, infrastructure automation plays a crucial role in ensuring efficient and reliable deployment processes. One popular tool for infrastructure as code (IaC) is Terraform, which allows you to define and provision cloud infrastructure using a high-level configuration language. GitHub Actions is another powerful tool that enables you to automate workflows and tasks within your GitHub repository. In this article, we will explore how to configure Terraform Apply GitHub Actions to run only on main push events, thereby streamlining your infrastructure automation process.
Understanding the Main Push Event
The main push event in GitHub refers to when changes are committed to the main branch of your repository. This event is often considered the primary branch for production-ready code, making it an ideal candidate for running infrastructure automation tasks. By configuring Terraform Apply GitHub Actions to run only on main push events, you can ensure that your infrastructure is provisioned or updated only when the codebase is in a stable and deployable state.
Setting Up Terraform Apply GitHub Actions
To set up Terraform Apply GitHub Actions to run only on main push events, you’ll need to follow these steps:
1. Create a new GitHub repository for your Terraform configuration and other related files.
2. Initialize a new Terraform workspace in the repository using the following command:
“`
terraform init
“`
3. Create a new file named `terraform.yml` in the `.github/workflows` directory of your repository. This file will define the workflow for Terraform Apply GitHub Actions.
4. Open the `terraform.yml` file and add the following content:
“`yaml
name: Terraform Apply
on:
push:
branches:
– main
jobs:
apply-terraform:
runs-on: ubuntu-latest
steps:
– name: Checkout repository
uses: actions/checkout@v2
– name: Set up Terraform
uses: hashicorp/[email protected]
with:
terraform-version: ‘1.2.6’
– name: Apply Terraform configuration
run: |
terraform apply -auto-approve
“`
5. Save the `terraform.yml` file and commit the changes to your repository.
Explanation of the Workflow
In the `terraform.yml` workflow file, we have defined the following:
– The `name` field specifies the name of the workflow, which is `Terraform Apply`.
– The `on` field defines the triggers for the workflow. In this case, we are listening for push events on the `main` branch.
– The `jobs` field contains the list of jobs that should be executed when the workflow is triggered. Here, we have defined a single job named `apply-terraform`.
– The `runs-on` field specifies the platform on which the job should run. In this example, we are using the `ubuntu-latest` platform.
– The `steps` field contains the list of steps that should be executed within the job. These steps include:
– Checking out the repository using the `actions/checkout@v2` action.
– Setting up Terraform using the `hashicorp/[email protected]` action and specifying the desired Terraform version.
– Applying the Terraform configuration using the `terraform apply -auto-approve` command, which automatically approves the changes for application.
By following these steps and configuring the `terraform.yml` workflow file, you can ensure that Terraform Apply GitHub Actions runs only on main push events, thereby streamlining your infrastructure automation process and maintaining a stable and reliable deployment environment.
