Lab 5: Overview

Table of Contents

You’ve learned how to download a project from GitHub and then modify the Dockerfile to create a custom image. Now, we will explore how to create our own Dockerfile to build a deployable Docker image.

Writing a Dockerfile

We will write our own Dockerfile to build an image to host a Python application using the Flask microframework. This method allows us to bundle an application in a state that includes the required packages an configurations. It makes it easy to deploy the application!

Goals for Lab 5

We will explore how to containerize applications so that we can run a service using multiple smaller containers.

During this lab, you will learn how to:

  1. create a basic Dockerfile

  2. daemonize a container to run in the background

  3. package a web application or internet service in a Docker image
