Dockerizing a Node App & Shipping It to Azure: Build, Break, Fix & Ship (3 Errors, Zero Regrets) 🐳
I wanted a hands-on project to actually cement what I'd been learning in Docker and Azure, build something small, break it, fix it, and ship it for real. So I built Container Vibes : a tiny Express app that hands you a random "vibe" (a color theme + a little quote) every time you click a button. It's deliberately simple. The point was never the app it was everything around it: containerizing it…
In the journey of learning Docker and Azure, the author decided to build a small project to solidify their knowledge. This project, called "Container Vibes," is a simple Express app that provides users with a random vibe (a color theme and a quote) each time they click a button. The focus was not on the app itself, but rather on the process of containerizing it, pushing it to a registry, and running it live on Azure Container Instances (ACI).
The author started by creating a clean folder structure for the project. They created a new folder named "docker-project-1" and opened it in VS Code. Inside this folder, they created another folder called "hagital" and navigated into it. Then, they initialized a new Node.js project using `npm init -y`, which generated a default `package.json` file without requiring the user to answer any prompts.
Next, the author created an empty `Dockerfile` file to serve as a placeholder for the Docker container configuration. After that, they created the actual app files, including a `server.js` file and a `.dockerignore` file.
