Docker, Kubernetes & AWS: Real-World Deployment in 25 Days

Discover how docker resolves development and deployment challenges by installing docker desktop and running ubuntu and python containers. Compare virtual machines with docker containers and enable effortless version switching.

Learn how a container creates an isolated, portable environment that bundles your app with all dependencies, including the OS, enabling lightweight, cloud-ready deployment across machines.

Launch your first Docker containers by running a hello-world image from the command line, demonstrating Docker Desktop, terminal access, and quick spins of Ubuntu and Node.js for deployment.

Docker Hub is the container registry hosting official pre-built images like ubuntu and fedora. Downloading images is free and requires no login to pull, but trust in official publishers matters.

Master linux shell commands for pwd, cd, ls, and navigating directories. Apply these basics in a docker ubuntu container with apt update and apt install, and run neofetch.

learn to run a web server inside a docker container, access it, and operate in detached mode, then manage, stop/start, inspect containers, and debug with logs and an interactive shell.

Explore ip addresses and port numbers, including ipv4 and ipv6, ip:port notation, localhost 127.0.0.1, and default ports like http 80, https 443, or ssh 22.

Learn how a web server delivers content over the internet by handling HTTP requests and responses between a browser and nginx, with HTTP 1.1 and HTTP/2 details.

Configure a container during Docker container create to attach a terminal (-t), enable interactivity (-i), and predefine ports, mounts, and environment variables before startup.

Launch an NGINX container and edit the index.html in its document root to show a light gray background and 'welcome to nginx in Docker', then expose the port.

Learn to use the nano text editor on the command line to create, edit, save with ctrl+o and quit with ctrl+x, and view files with cat in a Linux container.

Learn to deploy Docker on an AWS Ubuntu server, run an Apache web server, install and manage software, connect via SSH, and ensure containers boot reliably for production deployments.

Explore the AWS dashboard by learning how the account dropdown, region selection, and service list shape your view, with a focus on EC2 and S3 basics.

Demonstrates installing software on a server using apt, illustrated by cowsay. Covers removing packages and using apt autoremove to recover from upgrade issues.

Launches an apache web server in a docker container using the httpd image, and maps port 80. Edit the container's /usr/local/apache2/htdocs/index.html to customize the page.

Set up a Raspberry Pi to run Docker by installing Raspberry Pi OS on a microSD card with Raspberry Pi Imager, enabling SSH and Wi-Fi for headless access.

Configure ssh key authentication on a Ubuntu virtual machine, add the public key to authorized_keys, disable password and root logins, and restart ssh to secure access.

Discover how Docker stores files in a container and how to move them with docker cp. Compare bind mounts with host access and use -v to launch a web server.

Learn to use read-only bind mounts to prevent container writes to a host folder while keeping host changes visible in real time, using short form or mount syntax.

Diagnose AWS deployments by verifying domain resolution and nameserver alignment with the hosted zone; correct A records for root and www, then check SSH and HTTP/HTTPS security in default VPC.

Learn how to build a Node.js server that serves a simple website, install dependencies with npm, run the app on port 3000, and prepare for dockerfile migration.

Configure the container to run a default command with CMD, choose between exec form and shell form, and note that the last CMD takes effect.

Use a dockerignore file to exclude files and folders from the build context, reducing image size and speeding up builds with wildcard patterns like node_modules and Dockerfile.

Use the run command in dockerfiles to execute setup tasks during build, chain commands with &&, install dependencies with apt-get -y, and bake image layers for faster scaling.

Launch a private registry with https via Letsencrypt, configure with environment variables or a config file, then test push and pull over a 443 to 5000 port mapping.
