Learning Track
DevOps and Infrastructure
Linux, containers, Kubernetes, CI/CD, and the cloud.
A parent track containing 6 sub-tracks: Linux and the Command Line, Docker and Containerization, Kubernetes, CI/CD Pipelines, AWS, and Azure. Take in order for the full DevOps path; or pick the ones that match your specialty.
Sub-Tracks
Master the OS of the cloud.
Filesystem, essential commands, file permissions, processes + systemd, networking from the CLI, shell scripting, SSH + hardening, package management, awk/sed/cut, and vim basics. Ends with a passion project that hardens + deploys to a real $5 VPS.
First lesson: The Linux Filesystem
Ship containers like a working engineer.
Containers vs VMs, Docker fundamentals, writing Dockerfiles, Docker Compose, networking, volumes, registries (Hub + GHCR), multi-stage builds + security scanning, and a real multi-service app. Ends with a deployed passion project on a real VPS.
First lesson: What Containers Are and Why
Container orchestration at production scale.
Core concepts (Pods, Deployments, Services, ConfigMaps, Secrets), kubectl, rolling updates + probes, networking + Ingress, persistent storage, Helm, RBAC + autoscaling, managed K8s (EKS/GKE/AKS), and observability. Ends with a passion project deploying a multi-service Helm chart.
First lesson: What Kubernetes Is and When NOT to Use It
Build the pipeline that ships your team's code.
GitHub Actions in depth, complete CI workflows (lint + test + Docker push), CD pipelines (staging + production), environment + secret management, OIDC federation, testing in CI, security scanning, and deploy strategies (canary + blue/green). Ends with the job-readiness lesson.
First lesson: What CI/CD Is
The cloud platform that runs most of the internet.
Cloud landscape, AWS core services (EC2, S3, RDS, Lambda, IAM, VPC, CloudFront, Route 53), IAM in depth, EC2, S3, RDS, Lambda, VPC, CloudFront, AWS CLI + Terraform, and the AWS cert path. Ends with a passion project deploying a 3-tier app on AWS.
First lesson: The Cloud Landscape
The cloud platform that runs the Microsoft world.
Azure vs AWS, core services (VMs, Blob, Azure SQL, Functions, Entra ID, App Service), Entra ID in depth, App Service, Functions, Blob Storage, Azure DevOps, AKS, and the Azure cert path (AZ-900 / AZ-104 / AZ-204).
First lesson: Azure vs AWS
