DevOps and Infrastructure as Code
Infrastructure as Code (IaC) is the practice of managing infrastructure through code rather than manual configuration. Whether using Terraform, CloudFormation, Docker, or Kubernetes, AI can help you generate, optimize, and troubleshoot infrastructure code.
Docker and Containerization
Generating Dockerfiles
You: "Generate a Dockerfile for:
- Python 3.11 application
- FastAPI server
- Gunicorn production server
- Multi-stage build for optimization
- Non-root user for security"
AI: [Generates production-ready Dockerfile]
Optimizing Docker Images
You: "This Docker image is 800MB. Optimize it:
[paste Dockerfile]
Constraints:
- Must include Python dependencies
- Must run production server
- Should be as small as possible"
AI: [Shows optimization techniques]
[Uses multi-stage builds, better base images]
Infrastructure as Code
Terraform Configuration
You: "Generate Terraform to deploy:
- VPC with public/private subnets
- RDS PostgreSQL database
- ECS service running Docker
- Load balancer
- Auto-scaling
Provider: AWS"
AI: [Generates complete Terraform configuration]
CloudFormation Templates
You: "Generate CloudFormation template for:
- EC2 instance
- S3 bucket with public access
- Security groups
- IAM roles
Provider: AWS"
AI: [Generates CloudFormation YAML/JSON]
CI/CD Pipelines
GitHub Actions Workflow
You: "Generate GitHub Actions workflow for:
- Run tests on every push
- Build Docker image
- Push to ECR
- Deploy to ECS
- Run smoke tests
Language: Python
Framework: FastAPI"
AI: [Generates complete GitHub Actions workflow]
GitLab CI Pipeline
You: "Generate .gitlab-ci.yml for:
- Lint code
- Run unit tests
- Build and push Docker
- Deploy to Kubernetes
- Monitor deployment"
AI: [Generates GitLab CI configuration]
Kubernetes
Kubernetes Manifests
You: "Generate Kubernetes manifests for:
- Deployment (3 replicas)
- Service (LoadBalancer)
- ConfigMap for configuration
- Secret for credentials
- HPA for auto-scaling
App: Node.js service
Container: node:18"
AI: [Generates complete K8s manifests]
Helm Charts
You: "Generate Helm chart for:
- Multi-tier application
- Database
- Cache
- Web service
- Worker service
Configurable values:
- Replicas
- Image versions
- Resource limits"
AI: [Generates Helm chart structure]
Infrastructure Monitoring
Monitoring Setup
You: "Set up monitoring for:
- Application logs to CloudWatch
- Metrics to Prometheus
- Alerts for errors
- Dashboard in Grafana
Platform: AWS"
AI: [Generates monitoring configuration]
Alert Rules
You: "Define alert rules for:
- High error rate (>5% in 5 min)
- Database query time (>1s)
- Memory usage (>80%)
- Disk space (>90%)
Tool: Prometheus"
AI: [Generates alert rule definitions]
Security in Infrastructure
Security Groups
You: "Configure security groups for:
- Web tier (HTTP/HTTPS only)
- App tier (internal only)
- Database tier (restricted ports)
Allow traffic between tiers only
Provider: AWS"
AI: [Generates security group rules]
IAM Policies
You: "Generate IAM policy for:
- Application needs: read S3, write CloudWatch Logs
- Least privilege principle
- No wildcards in actions
Provider: AWS"
AI: [Generates restrictive IAM policy]
Infrastructure Troubleshooting
Debugging Deployment Issues
You: "Deployment fails with error:
[error message]
Logs:
[paste logs]
Infrastructure:
[describe setup]
What's wrong?"
AI: [Analyzes error]
[Provides debugging steps]
[Suggests fixes]
Performance Issues
You: "Application running on ECS is slow.
CloudWatch metrics:
[paste metrics]
Configuration:
[paste task definition]
What's the bottleneck?"
AI: [Identifies performance issue]
[Suggests optimization]
Real-World Scenarios
Scenario 1: Blue-Green Deployment
You: "Implement blue-green deployment for:
- Zero-downtime updates
- Rollback capability
- Load balancer switching
Framework: Terraform + AWS"
AI: [Generates blue-green strategy]
Scenario 2: Database Migration
You: "Plan database migration:
- Prod: PostgreSQL on EC2
- New: RDS PostgreSQL
- Zero downtime
- Rollback plan
Data size: 500GB"
AI: [Shows safe migration strategy]
Scenario 3: Multi-Region Deployment
You: "Deploy application to 3 regions:
- US East
- US West
- Europe
High availability
Disaster recovery
Framework: Terraform"
AI: [Generates multi-region infrastructure]
Infrastructure Best Practices
State Management
You: "How should I manage Terraform state?

- Backup?
- Secrets in state?"
AI: [Explains state management best practices]
Code Organization
You: "How should I organize Terraform code for:
- Multiple environments (dev, staging, prod)
- Multiple regions
- Shared modules
- Easy maintenance"
AI: [Shows directory structure and patterns]
Exercises
