Web Infrastructure - ALU Course Supplement [Web Servers, Load Balancers and SSL Termination]

With this video I will go over the basic steps you need to take to set up a complete web infrastructure using Docker! This walkthrough covers:

🔹 Setting up multiple web servers (Nginx) in Docker containers
🔹 Configuring HAProxy as a load balancer with roundrobin algorithm
🔹 Implementing SSL termination with self-signed certificates
🔹 HTTP to HTTPS redirection
🔹 Custom Docker network configuration

FOR MY STUDENTS: There is a slight difference between the actual web-01, web-02 and lb-01 servers you are using for your work. This environment is a simulation of that architecture with minor differences. Since in this context we are using docker containers that share an internal bridged network (unlike the EC2 VPS instances you have that have Public IPs and discover-able on the internet ), the way we SSH into them and access content they serve will be slightly different from the real servers. In addition to that, docker containers use a stripped down linux distribution (Alpine Linux by default but we are using Ubuntu24.04 image), which doesn't come with some of the things we love like systemd(systemctl), background system daemon, ifconfig and such. However, most of the things you need like the SSH service, wget, ip tools, text editors (vim and nano) are already installed (check the DOCKERFILE). You can install other tools as needed.

The lab uses Docker Compose to orchestrate two web servers and a load balancer, demonstrating real-world deployment patterns.
