Docker Essentials: A Crash Course in Container Technology

Define DevOps and its impact on efficiency, collaboration, and performance in the software development life cycle. Discover continuous integration and delivery, automated testing and deployment, and infrastructure as code.

Explore how Docker uses containerization to package applications and dependencies into portable containers, ensuring isolation and consistent performance across development, testing, and production environments.

Install Docker on Ubuntu 22.04 using official packages, install prerequisites like certificates, curl, gnupg, set up Docker's repo and GPG key, add user to Docker group, and run hello world.

Learn how to set up a private Docker network, create and manage a bridged network with a specific subnet and gateway, and use Docker network commands to connect containers.

create a multi-stage dockerfile using a go language base, copy source code, set work directory, compile in the builder image, and transfer to a busybox final image for running.

Build and run docker images with docker compose using a two-stage dockerfile for a Go project, learn contexts, networks, and how to run and inspect containers.

Master core docker concepts and essential commands through a hands-on recap of networks, images, containers, inspect, and compose, including a multi-stage Dockerfile example and practical workflow.

Learn to build and run core PHP using nginx, MySQL, and php-fpm, while adopting cloud registry practices by pushing images to a local registry and pulling for deployment.

Learn to set up MySQL with Docker Compose: use the official MySQL image, configure environment variables, map ports, persist data with volumes, and access via Adminer.

Build a MySQL image with docker compose using default MySQL image; run MySQL and Adminer containers, map ports, persist data with a host volume, and access MySQL by service name.

Learn to build PHP and Nginx containers with Docker, reuse a core PHP image, configure PHP.ini and PHP-FPM settings, and run a startup script for ongoing service.

Create an nginx dockerfile using the alpine image, copy code from the php image, and configure site-enabled hosts for http and https with a self-signed certificate.

Build and run a two-service docker compose setup for PHP and Nginx. Build images, bring containers up, and use volume mounts to sync code from host to container.

Review Docker-based PHP, MySQL, and Nginx deployments, including building a PHP 8.2 image on Alpine, using a local registry, and mastering volume mounts and service-name networking.

Reuse the PHP, MySQL, and Nginx docker setup to build a Laravel app, install BC Math and PDO MySQL, and configure docker and nginx for Laravel with docker compose.

Build and run a Laravel application with Docker Compose, handle composer installation and Dockerfile tweaks, and access the app through a unique host port and Nginx setup.

Learn to make a Node.js application run in Docker by building a dockerized setup with a Dockerfile, npm install, and volume mounting, exposing port 8000 and using docker-compose to run.

Set up a react application with docker compose and dockerfile, expose port 3000, and install npm packages. Copy node_modules between container and host to ensure a functioning dev environment.

Conclude the course by revisiting Docker fundamentals, from installing and networking to Docker Compose and volumes, and outline how containerized apps enable DevOps, CI/CD, and cloud deployment.
