DevOps & Infrastructure¶

Comprehensive reference covering Docker, Kubernetes, CI/CD, Terraform, cloud platforms, monitoring, SRE practices, and data center networking.

Containers & Docker¶

• docker fundamentals - containers, images, volumes, networking, lifecycle
• dockerfile and image building - Dockerfile syntax, multi-stage builds, optimization
• docker compose - multi-container orchestration, service discovery
• docker for ml - ML-specific Docker patterns, JupyterLab, MLflow, Model Runner

Kubernetes¶

• kubernetes architecture - control plane, worker nodes, CNI, cluster deployment
• kubernetes workloads - Pods, Deployments, StatefulSets, DaemonSets, ConfigMaps, Secrets
• kubernetes services and networking - Services, Ingress, TLS, cert-manager, DNS
• kubernetes storage - PV, PVC, StorageClass, CSI drivers, cloud storage
• kubernetes resource management - requests, limits, QoS, namespaces, quotas, HPA, autoscaling
• kubernetes on aks - Azure AKS, ACR, Azure AD, monitoring, virtual nodes
• kubernetes on eks - AWS EKS, ECR, EBS/EFS, ALB Ingress Controller

Package Management & Templating¶

• helm package manager - charts, templates, hooks, releases, repositories, secrets

CI/CD & Automation¶

• cicd pipelines - GitHub Actions, Azure DevOps, pipeline stages, multi-environment
• jenkins automation - Jenkinsfile, shared libraries, Docker agents, credentials
• gitops and argocd - ArgoCD, sync waves, app-of-apps, Sealed Secrets, Crossplane

Infrastructure as Code¶

• terraform iac - HCL, state, modules, workspaces, cloud providers
