I had written Customer Store Mean Stack app that performs simple basic CRUD (Create, Read, Update, Delete) operations on the Customer model sometime back which I will be dockerizing here.

If you have some basic idea about Docker or have just heard about it and want to learn how to dockerize Mean Stack app then this article is for you.

What Is Docker?

In brief, Docker is an open source DevOps tool designed to help developers and operations guys to streamline application development and deployment.

By dockerizing an application means deploying and running an application using containers.

Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and deploy it as one package.

By doing so application can be deployed on any target environment/machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code. 

Thus removing the deployment issues that occur due to various environment spec mismatch. To learn more about docker checkout this link.

Prerequisite

  • First, we need to have docker installed on our machine so that we can build docker image and run docker containers. There are different installation for Mac and Windows. 
  • For Windows 10 Professional and Enterprise install docker for desktop from this link but if you have Windows 10 Home edition like I have then you will have to installed Docker Toolbox from this link
  • Download the appropriate installer and follow the instructions.
  • We also need to have account at Docker Hub registry so that we can pull and push Docker images. It’s free so if you already haven’t one, checkout this linkto create one for yourself. 
  • Last, we need Mean Stack application that we want to dockerize. So if you already have one that’s great but if you don’t then you can get my Customer Store Mean Stack app code that I am using in this article from my GitHub repository from this link.
