Introduction
This guide focuses on the essential tools for modern deployment: Docker for containerization and Kubernetes for orchestration.
🚀 DevOps Crash Course
Essential commands you'll use daily:
# Docker
docker build -t my-app .
docker run -p 8080:80 my-app
# Kubernetes
kubectl get pods
kubectl logs -f my-pod
kubectl apply -f deployment.yaml🎯 Expected Outcome
By the end of this guide, you will be able to:
- Write optimized Dockerfiles and manage multi-container apps with Docker Compose.
- Deploy and manage applications on Kubernetes clusters.
- Understand K8s primitives: Pods, Services, Deployments, Ingress.
- Implement CI/CD workflows for containerized applications.
Capstone: End-to-End GitOps Pipeline
Implement a full GitOps pipeline using ArgoCD to deploy a microservices application to a Kubernetes cluster.
- Infrastructure: Provision a K8s cluster (Minikube or Kind) using Terraform.
- CI: GitHub Actions pipeline to build, test, and push Docker images.
- CD: ArgoCD to sync the cluster state with a Git repository (GitOps).
- Monitoring: Prometheus and Grafana for cluster observability.
- Security: Implement Network Policies and RBAC.
Document the entire pipeline flow, including disaster recovery procedures.
