# Introduction

 
Before leaping into the tasks, let’s clear up what Docker is and why individuals care about it. Docker packages an utility and every part it wants right into a container. A container is a light-weight, remoted setting that runs the identical manner in all places. No “works on my machine” issues. If it runs in your laptop computer, it runs the identical on a server or the cloud. Developers love that as a result of sharing code turns into easy and predictable. In this “5 Fun Projects” sequence, our focus is on studying by doing. Every undertaking teaches one core Docker talent. By the tip, you gained’t simply know Docker in concept — you’ll perceive find out how to use it.

 

# 1. Static Website Hosting with Nginx and Docker

 
This video by Techdox reveals you find out how to host a web site utilizing Nginx in Docker. You containerize an online server, add your web site information, and run every part in a single container. The tutorial walks by means of making a easy Dockerfile (or Docker Compose), establishing Nginx to serve your pages, and beginning the container so the positioning is stay. There is not any want to put in Nginx in your machine as a result of all of it runs inside Docker. This retains the setup clear and reproducible.

 

# 2. Multi-Container Docker Applications with Docker Compose

 
This video reveals find out how to use Docker Compose to run two providers collectively: a Python Flask backend and a Redis database. All service configurations, together with builds, ports, and connections, are outlined in a single docker-compose.yml file. You begin every part with a single command, docker compose up. The containers talk mechanically, and setting settings keep centralized. This makes it straightforward to run and handle the app on any machine whereas giving a sensible instance of dealing with a number of providers in Docker.

 

# 3. One Database Shared by Multiple Containers

 
In this One Database service for Multiple Docker container Services video, the creator reveals find out how to run a single database container and let a number of utility containers connect with it. You arrange MySQL or one other database as soon as in Docker, and every service runs in its personal container however connects to the identical database by means of a shared Docker community or correct port mapping. You discover ways to configure networking, expose the database port, and hyperlink containers for safe communication. This method helps save sources by centralizing databases and likewise teaches when a shared database works finest versus separate situations.

 

# 4. Automated Continuous Integration with Jenkins in Docker

 
These movies present find out how to construct a whole steady integration (CI) pipeline utilizing Jenkins inside Docker to mechanically create Docker pictures when code modifications. The first video, Build & Push React Docker Image with a Jenkins Pipeline, walks you thru establishing the Jenkins container, making a pipeline to drag supply code, construct a Docker picture, and optionally run checks or push the picture to a registry. The second video, Automated CI with Jenkins on Docker to Build Docker Images, focuses on a React app, displaying find out how to join Jenkins to the supply repository, construct and tag Docker pictures, and push them mechanically. Both tutorials present how containerizing Jenkins retains your construct setting remoted, reproducible, and constant. Once arrange, each code replace triggers a contemporary construct, making deployments dependable and automatic.

 

# 5. Logging and Monitoring Docker

 
These movies present find out how to construct a full observability stack utilizing Docker. Prometheus collects system and container metrics. Loki shops logs. Grafana shows every part in real-time dashboards. In the primary video, Loki, Prometheus, Grafana & Docker: Logging & Monitoring, you’ll study to arrange Docker for every service, join them appropriately, and hyperlink metrics with logs to see how your containers carry out. The second video, Server Monitoring: Prometheus and Grafana Tutorial, focuses on monitoring servers or container environments utilizing Prometheus and Grafana in a conveyable, reproducible setup. It reveals find out how to configure Prometheus as Grafana’s information supply, arrange metrics endpoints, and create dashboards to trace CPU, reminiscence, and container efficiency. Both approaches depend on containerization, making the stack straightforward to run, replicate, and broaden on any machine.

 

# Wrapping Up

 
These 5 tasks construct your Docker expertise one layer at a time. You host a web site, join a number of providers, share databases, automate builds, and monitor every part. Each undertaking offers sensible expertise you should use in actual work. Now it’s your flip to attempt these tasks and discover Docker your self.
