๐Ÿ”— Learning Resources

๐Ÿ”’ Security

  • All infrastructure encrypted at rest
  • RBAC with least privilege access
  • Network policies enforcing microsegmentation
  • Secrets managed via HashiCorp Vault
  • Regular security scanning with Trivy
  • Compliance with CIS benchmarks

๐Ÿงช Testing

# Terraform validation
terraform validate
terraform plan -out=tfplan

# Security scanning
checkov -d terraform/

# Kubernetes manifest validation
kubeval kubernetes/manifests/**/*.yaml

# Docker image scanning
trivy image my-image:latest

๐Ÿ“Š Monitoring & Observability

Metrics, logs, and traces collected from:

  • Kubernetes API Server
  • Node exporters
  • Application pods
  • AWS CloudWatch / Azure Monitor

Access Grafana dashboards at: http://grafana.yourdomain.com

๐Ÿ”„ Production Deployment

# 1. Validate infrastructure
terraform validate
terraform plan -out=tfplan

# 2. Apply infrastructure
terraform apply tfplan

# 3. Deploy application
helm upgrade --install my-app ./helm/app-chart \
  -f helm/app-chart/values-production.yaml \
  --namespace production \
  --create-namespace

# 4. Verify deployment
kubectl rollout status deployment/my-app -n production
kubectl get pods -n production
