Docker & Kubernetes: The Complete Practical Guide

Install Docker Desktop for Windows to create a Linux virtual machine and run Linux containers. Download from Docker Hub, restart Windows, and set up PowerShell to use Docker commands.

Explore running a BusyBox container, compare its small image slightly over 1 megabyte to Ubuntu, and use BusyBox's built-in utilities like echo, uptime, mkdir, and touch while discussing image tags.

Pull and compare Alpine and BusyBox images to understand how Alpine, a small Linux based on BusyBox, uses APK to install packages and serve as a base image.

Learn to run Nginx from its image in a docker container, expose port mappings from external port 8080 to internal port 80, and test http access.

Learn to serve a custom HTML page with an Nginx container using port mapping and volume mapping, editing locally and seeing live updates in the browser.

Learn to add a favicon to an nginx container by generating the icon with favicon.io, linking it in html, and testing the updated page in a docker volume setup.

Run containers in the background with docker run -d, see how inner processes affect lifetime, and use docker logs and docker stop to manage and inspect activity.

Learn docker run options for pseudo tty and interactive mode, including -t/--tty and -i/--interactive, and how -it connects to a container shell.

Create and run two distinct nginx containers from separate folders, map volumes, and expose them on two external ports; verify content updates in the browser.

Learn to clean up stopped containers in Docker: stop, remove, and prune using Docker rm and Docker container prune. List all containers with Docker ps -a and verify clean state.

Learn to create a python container by pulling the python image from docker hub, running an interactive session with docker run -it, and exploring modules and help.

Explore Docker workflows and a Python calendar app challenge using the calendar module. Build and run calendar app.py inside a container with Python three, including volume mapping and working directory.

Learn to handle sigint and sigterm in a Node.js express app inside docker, using process.on to terminate correctly with exit code 0, and compare docker stop and docker kill.

Learn to start additional processes inside a running docker container with docker exec or docker container exec, running bash or mongo shell, and observe mongod running alongside.

Explore how a docker entrypoint script starts the mongod process in a mongo container, inspect container details with docker inspect, and locate entrypoint files to connect with the mongo shell.

run a WordPress container using the WordPress image, map port 80 to access the setup, and configure WordPress with a MySQL database hosted externally.

Establish container-to-container communication on the default bridge network by booting two BusyBox instances, verifying their 172.17.0.0/16 IPs with ping and docker inspect.

Verify MySQL container environment variables with docker exec and env, then launch a phpMyAdmin container, map ports, and configure the host connection using an environment variable.

Connect phpMyAdmin to a MySQL container by setting PMA_HOST to the MySQL container IP and starting phpMyAdmin with environment variables. Verify access to the databases.

Create three docker containers: MySQL, phpMyAdmin, and WordPress, on a custom network named WordPress. Connect WordPress to MySQL using four environment variables.

Set up a custom Docker network and deploy WordPress, MySQL, and phpMyAdmin containers; configure environment variables, test connectivity, and access WordPress on port 8080 and phpMyAdmin on 8081.
