This is a Node.js application using Fastify, packaged in a Docker container.

Prerequisites

• Docker installed on your machine

Building the Docker Image

To build the Docker image, run the following command in the directory containing the Dockerfile:

sudo docker build -t more-complicated-app:alpine .

Running the Docker Container

sudo docker run -it -p 8080:8080 --name my-app --rm --init more-complicated-app:alpine

This command will:

• Run the container interactively (-it)
• Map port 8080 on your host to port 8080 in the container (-p 8080:8080)
• Name the container my-app (--name my-app)
• Remove the container when it exits (--rm)
• Use the tini init system to handle reaping zombie processes (--init)

Accessing the Application

http://localhost:8080
