🏗️ Infrastructure Setup

Step 1: AWS Account Setup

Create AWS Account

→ Go to https://aws.amazon.com/free/
→ Sign up for Free Tier account
→ Complete email verification
→ Add payment method (required but won't be charged for Free Tier usage)

Create IAM User for Terraform

# Login to AWS Console → IAM → Users → Add User

Username: terraform-user
Access type: ☑ Programmatic access
Permissions: ☑ AdministratorAccess (for learning; use restricted policies in production)

# Download credentials CSV file
# Save Access Key ID and Secret Access Key securely

Create EC2 Key Pair

# AWS Console → EC2 → Key Pairs → Create Key Pair

Name: devops-project-key
Type: RSA
Format: .pem

# Download and save to ~/.ssh/
mv ~/Downloads/devops-project-key.pem ~/.ssh/
chmod 600 ~/.ssh/devops-project-key.pem

Step 2: Terraform Infrastructure

Initialize Terraform

cd terraform/environments/dev

# Initialize Terraform (downloads providers)
terraform init

# Output:
# Initializing modules...
# Initializing the backend...
# Initializing provider plugins...
# Terraform has been successfully initialized!

Validate Configuration

# Validate Terraform syntax
terraform validate

# Output:
# Success! The configuration is valid.

Plan Infrastructure

# Generate and review execution plan
terraform plan -out=tfplan

# Output shows:
# - Resources to be created
# - Changes to existing resources
# - Resources to be destroyed

Apply Configuration

# Apply the planned changes
terraform apply tfplan

# Review the plan one more time, then confirm with: yes

# Output:
# aws_vpc.main: Creating...
# aws_internet_gateway.main: Creating...
# aws_subnet.public: Creating...
# aws_security_group.web_sg: Creating...
# aws_instance.web_server: Creating...
# 
# Apply complete! Resources: 8 added, 0 changed, 0 destroyed.
#
# Outputs:
# web_server_public_ip = "54.123.45.67"

Get Outputs

# View all outputs
terraform output

# Get specific output
terraform output web_server_public_ip

# Use output in scripts
EC2_IP=$(terraform output -raw web_server_public_ip)
echo "EC2 IP: $EC2_IP"

Step 3: Verify Infrastructure

# Check EC2 instance status
aws ec2 describe-instances \
  --filters "Name=tag:Project,Values=devops-resume" \
  --query 'Reservations[*].Instances[*].[InstanceId,State.Name,PublicIpAddress]' \
  --output table

# Test SSH connectivity
ssh -i ~/.ssh/devops-project-key.pem ec2-user@$EC2_IP "echo 'Connection successful!'"

ssh -i ~/.ssh/devops-project-key.pem ec2-user@YOUR_EC2_IP

# Check Nginx status
sudo systemctl status nginx

# View Nginx logs
sudo tail -f /var/log/nginx/access.log
sudo tail -f /var/log/nginx/error.log

# Check application files
ls -la /opt/devops-resume-app/

Making Changes to Application

# 1. Update application files locally
vim app/index.html

# 2. Commit and push changes
git add app/index.html
git commit -m "Update application content"
git push origin main

# 3. GitHub Actions will automatically:
#    - Detect changes
#    - Run Ansible playbook
#    - Deploy updated application

# 4. Verify changes
curl http://YOUR_EC2_IP

Manual Redeployment

# Redeploy application only (no infrastructure changes)
cd ansible
ansible-playbook -i inventory/hosts playbooks/deploy_webapp.yml

# Redeploy specific tasks
ansible-playbook -i inventory/hosts playbooks/deploy_webapp.yml --tags "nginx"

# Force recreation of resources
cd terraform/environments/dev
terraform taint aws_instance.web_server
terraform apply

📊 Monitoring & Maintenance

Health Checks

# HTTP health check
curl -I http://YOUR_EC2_IP/health

# Expected output:
# HTTP/1.1 200 OK
# Content-Type: text/plain
# ...

# Continuous monitoring script
./scripts/monitor.sh YOUR_EC2_IP

Logs

# Nginx access logs
ssh -i ~/.ssh/devops-project-key.pem ec2-user@YOUR_EC2_IP \
  "sudo tail -f /var/log/nginx/access.log"

# Nginx error logs
ssh -i ~/.ssh/devops-project-key.pem ec2-user@YOUR_EC2_IP \
  "sudo tail -f /var/log/nginx/error.log"

# System logs
ssh -i ~/.ssh/devops-project-key.pem ec2-user@YOUR_EC2_IP \
  "sudo journalctl -u nginx -f"

Resource Monitoring

# Check EC2 instance status
aws ec2 describe-instances \
  --instance-ids i-YOUR_INSTANCE_ID \
  --query 'Reservations[*].Instances[*].[InstanceId,State.Name,InstanceType,PublicIpAddress]' \
  --output table

# Check infrastructure state
cd terraform/environments/dev
terraform show

# List all resources
terraform state list

Backup & Recovery

# Backup Terraform state
cd terraform/environments/dev
cp terraform.tfstate terraform.tfstate.backup

# Export current infrastructure
terraform show -json > infrastructure_backup.json

# Backup application files
ssh -i ~/.ssh/devops-project-key.pem ec2-user@YOUR_EC2_IP \
  "sudo tar -czf /tmp/app_backup.tar.gz /opt/devops-resume-app/"
scp -i ~/.ssh/devops-project-key.pem \
  ec2-user@YOUR_EC2_IP:/tmp/app_backup.tar.gz ./backups/
