So far in this series, we’ve:
- Learned Terraform fundamentals
- Built reusable modules
- Managed remote state
- Designed production-ready structure
- Compared workspaces vs environments
- Deployed VPC and real AWS architecture
- Built a 3-tier system
Now we complete the journey 🔥
👉 Automating Terraform using CI/CD
🎯 What You’ll Learn
In this guide:
- Why CI/CD is important for Terraform
- How to automate Terraform with GitHub Actions
- Safe deployment practices
- Production workflow
🔁 Why CI/CD for Terraform?
Without CI/CD:
❌ Manual deployment
❌ Human errors
❌ No consistency
With CI/CD:
✅ Automated workflows
✅ Consistent deployments
✅ Safer infrastructure changes
🏗️ CI/CD Workflow Overview
Developer → Git Push
↓
GitHub Actions
↓
Terraform Plan
↓
Approval (optional)
↓
Terraform Apply
📁 Project Structure
.github/
workflows/
terraform.yml
🔹 GitHub Actions Example
name: Terraform CI/CD
on:
push:
branches:
- main
jobs:
terraform:
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout@v3
- name: Setup Terraform
uses: hashicorp/setup-terraform@v2
- name: Terraform Init
run: terraform init
- name: Terraform Plan
run: terraform plan
- name: Terraform Apply
run: terraform apply -auto-approve
🔐 Security Best Practices
👉 Never hardcode AWS credentials
Use:
- GitHub Secrets
- IAM roles
- Least privilege access
🧠 DevOps Insight
CI/CD enables:
- Team collaboration
- Safe infrastructure changes
- Faster deployments
👉 This is how modern DevOps teams operate.
⚠️ Important Note
Avoid:
❌ Direct auto-apply in production
❌ No approval process
👉 Always use review before apply
🎯 What You Just Learned
- Terraform automation
- CI/CD pipeline design
- Production workflow
