Terraform CI CD Pipeline with GitHub Actions Tutorial

In this tutorial, we will learn how to create a Terraform CI CD pipeline with GitHub Actions. Terraform is a popular infrastructure as code (IaC) tool that allows you to manage and provision infrastructure resources such as virtual machines, networks, and databases. GitHub Actions is a continuous integration and continuous deployment (CI/CD) platform that allows you to automate your build, test, and deployment pipeline.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• A GitHub account
• A Terraform installation on your machine
• A basic understanding of Terraform and GitHub Actions

If you are new to Terraform, you can check out our More Terraform Tutorials to get started.

Step 1: Create a New GitHub Repository

Create a new GitHub repository to store your Terraform configuration files. You can do this by logging into your GitHub account and clicking on the “New” button.

git init
 git add .
 git commit -m "Initial commit"
 git remote add origin https://github.com/your-username/your-repo-name.git
 git push -u origin master

Step 2: Create a Terraform Configuration File

Create a new file called `main.tf` in the root of your repository. This file will contain your Terraform configuration.

provider "aws" {
  region = "us-west-2"
}

resource "aws_instance" "example" {
  ami           = "ami-0c94855ba95c71c99"
  instance_type = "t2.micro"
}

Step 3: Create a GitHub Actions Workflow File

Create a new file called `.github/workflows/terraform.yml` in the root of your repository. This file will contain your GitHub Actions workflow configuration.

name: Terraform

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Install Terraform
        uses: hashicorp/[email protected]
      - name: Initialize Terraform
        run: terraform init
      - name: Apply Terraform configuration
        run: terraform apply -auto-approve

Step 4: Store Your AWS Credentials as GitHub Secrets

Store your AWS credentials as GitHub secrets so that GitHub Actions can use them to authenticate with AWS.

You can do this by going to your repository settings, clicking on “Actions” in the left-hand menu, and then clicking on “Secrets”.

Common Mistakes

Here are some common mistakes to watch out for when creating a Terraform CI CD pipeline with GitHub Actions:

• Forgetting to store your AWS credentials as GitHub secrets
• Not specifying the correct AWS region in your Terraform configuration
• Not using the correct Terraform version in your GitHub Actions workflow

Conclusion

In this tutorial, we learned how to create a Terraform CI CD pipeline with GitHub Actions. We covered the prerequisites, created a new GitHub repository, created a Terraform configuration file, created a GitHub Actions workflow file, and stored our AWS credentials as GitHub secrets.

By following these steps, you can automate your infrastructure provisioning and deployment using Terraform and GitHub Actions. For more information on Java Algorithms and Mastering SQL, check out our other tutorials.
