In this tutorial, we will dockerize a Node,Express and Mongo Application. We will be using a Docker Linux container.
When our applications are ready for deployment, we have to configure a production machine with all the dependencies for the application. This is often a tedious and time consuming job. To make this approach easy, we can make use of Docker.
Let’s first take an overview of Docker and then we will directly jump to the implementation of the application.
What is Docker and why to use it?
When our applications are ready for deployment, we have to configure a production machine with all the dependencies for the application. This is often a tedious and time consuming job. To make this approach easy, we can make use of Docker.
Docker provides a way to run applications securely and isolated in a container with all the applications dependencies packaged in it. Docker containers wrap up software and its dependencies into a standardized unit for software development. This makes sure that all the dependencies to run the application are packaged so that application will always run.
Some additional advantages of using Docker are:
- Once a docker image is created with all its dependencies, you need not worry about the operating system configuration for your application deployment. Since Docker is platform independent, a docker image that has successfully build can run on any platform using docker.
- This docker image can be easily shared with a client (or anyone) who wants to use the application. They can run the application simply by installing docker on their machine.
Docker can be downloaded from this link.
