Learn how Kubernetes Pods, Deployments and Services fit together by deploying a web app, exposing it, scaling it and running a rolling update with rollback.
A practical kubectl reference: manage contexts and namespaces, inspect and change resources, debug pods with logs and exec, and run safe rollouts and rollbacks.
Install the Traefik Ingress controller with Helm, route traffic by host and path to your Services, and issue free Let's Encrypt certificates with cert-manager.
Give Kubernetes workloads durable storage: set up a StorageClass, create PersistentVolumeClaims, use them in StatefulSets and mount a shared NFS volume.
Install Docker Engine and the Compose plugin from Docker's official repository on Ubuntu 24.04, Debian 12 or Rocky Linux 9, cap log size and verify it works.
Learn the everyday Docker commands by doing: run and inspect containers, read logs, open a shell, manage images, volumes and networks, and clean up disk space.
Write a production-ready Dockerfile for a Python web app: layer caching, .dockerignore, a non-root user, health checks and a multi-stage build, then test it.
Learn Docker Compose on Ubuntu 24.04 by building a Python and Redis app with a compose.yaml file, health checks, volumes, networks and environment variables.
Understand Docker network drivers on Ubuntu 24.04: create bridge networks with DNS, publish ports safely, use host and none modes, and set up overlay networks.
Keep container data safe on Ubuntu 24.04 with Docker named volumes, bind mounts and tmpfs, then back up, restore and migrate volumes with plain tar commands.
Read and filter Docker container logs, set up log rotation, and diagnose containers that crash, run out of memory, cannot bind ports or fill the disk on Ubuntu.
Shrink Docker images with slim bases, layer ordering, .dockerignore, BuildKit cache mounts and multi-stage builds, then inspect and scan the result with Trivy.
Harden Docker on Ubuntu 24.04: lock down the daemon, build non-root images, scan them with Trivy, run least-privilege containers and keep secrets out of images.
Build a Kubernetes cluster on Ubuntu 24.04 with kubeadm and containerd: prepare the nodes, initialize the control plane, add Flannel and join worker nodes.
