Git commit graphs, interactive rebasing, merge strategies, Trunk-Based Development, and GitOps.
Containers vs VMs, Docker daemon, container lifecycle, Docker Hub, and port mapping.
Layer caching, multi-stage builds, non-root users, .dockerignore, and slimming image sizes.
docker-compose.yml, multi-container networking, persistent volumes, and environment variables.
Control Plane (API Server, etcd, scheduler), Worker Nodes (kubelet, kube-proxy), and Pod lifecycle.
Deployments (replicas, rolling updates), ClusterIP/NodePort/LoadBalancer Services, and Ingress routing.
Continuous Integration, automated testing, continuous deployment workflows (.github/workflows), and secrets.
