Ship and operate containers with confidence.
From the Linux terminal and Docker to HTTP debugging and Kubernetes. Learn the operational skills that keep a service running after it is deployed.
Each step assumes only what came before it. Follow the sequence or jump to a course you need.
Move confidently through a Linux machine: navigate files, change permissions, pipe commands, process text, inspect processes and write scripts that automate the boring parts.
Understand images, containers, layers, volumes and networks. Write a production-minded Dockerfile, compose a multi-service stack and reduce the attack surface of what you ship.
Follow a request from DNS to TCP, TLS and HTTP. Learn headers, caching, status codes, latency, CDNs and the security basics that explain most production incidents.
Learn the Kubernetes objects that matter: pods, deployments, services, configuration, ingress, storage, scaling and observability. Finish by deploying a real application.
Containerise a small API and run it on Kubernetes with logs, metrics and a rollback.
Take a small API, write a multi-stage Dockerfile, deploy it with a Deployment, Service and Ingress, add probes and configuration, then run a rolling update and a rollback.
DeliverableThe Dockerfile, Kubernetes manifests, a deployment runbook and a screenshot of the rollout.
