Then, I’m telling it that I want to build a container called api using the image webapp-api (which is the image we defined on our API Dockerfile) that will be listening on port 9000. You should read all about docker-compose here.īasically, I’m telling Docker that I want to build a container called client, using the image webapp-client (which is the image we defined on our Client Dockerfile) that will be listening on port 3000. api:/api - /api/node_modules depends_on: - mongodb networks: webappnetwork client:/client - /client/node_modules links: - api networks: webappnetwork api: image: webapp-api restart: always ports: - "9000:9000" volumes:.

Write this code in the docker-compose.yml file:.

On your App main folder, create a new file and name it docker-compose.yml.

Open the React/Express App in your code editor.

Let me show you how simple it is to use it: Compose is a tool for defining and running multi-container Docker applications. In our case we have 3 containers to manage, so we will use docker-compose instead. You could run each individual container using the Dokerfiles. This will instruct docker to build an image (using these configurations) for our API. api/ # Make port 80 available to the world outside this containerEXPOSE 80 # Run the app when the container launchesCMD # Use a lighter version of Node as a parent imageFROM mhart/alpine-node:8.11.4 # Set the working directory to /apiWORKDIR /api # copy package.json into the container at /apiCOPY package*.json /api/ # install dependenciesRUN npm install # Copy the current directory contents into the container at /apiCOPY.

To build our API image you will be needing another Dockerfile. This will instruct docker to build an image (using these configurations) for our Client. client/ # Make port 3000 available to the world outside this containerEXPOSE 3000 # Run the app when the container launchesCMD

# Use a lighter version of Node as a parent imageFROM mhart/alpine-node:8.11.4 # Set the working directory to /clientWORKDIR /client # copy package.json into the container at /clientCOPY package*.json /client/ # install dependenciesRUN npm install # Copy the current directory contents into the container at /clientCOPY.

Open the React/Express App in your favorite code editor (I’m using VS Code).

To build our Client image you will be needing a Dockerfile. Docker containers everywhere!Ĭontainerizing your app with Docker is as simple as creating a Dockerfile for each of your apps to first build an image, and then running each image to get your containers live. Docker can build images automatically by reading the instructions from a Dockerfile. You’re all set to start containerizing stuff :)Īccording to documentation: a Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

If you opt for using the repo, don't forget to npm install inside the Client and API folders to install all needed dependencies.

You can follow that tutorial first or you can clone this GitHub repository with the boilerplate if you’re not interested in the process of creating React and Express apps.

I will use the React/Express app we have built in the previous tutorial called Create a React FrontEnd, a Node/Express BackEnd and connect them together.

Make sure you have Node and Docker running on your machine.

This is awesome if you are developing in your machine and then you want to deploy it to some cloud provider like GCP or AWS. If one goes rogue, you can kill it and make another just like it with no effort thanks to the container images system.Īnother thing that makes Docker great is that the app inside containers will run the same in every system (Windows, Mac, or Linux).

This makes containers very light, fast and secure.Ĭontainers are also meant to be disposable. It lets you run apps inside containers that are mostly isolated from “everything”.Įach container is like an individual virtual machine stripped out of everything that is not needed to run your app. Why should you care about Docker?ĭocker is simply one of the most important technologies at the moment.

The objective is to give you a practical guide of how to containerize this simple Full-Stack App, to be used as a starting point, for you to build your own apps. Instead, I will leave links, in case you want to learn more about any of them. I won’t go into much detail about how to work with any of the technologies. In this tutorial, I will guide you through the process of containerizing a React FrontEnd, a Node/ Express API, and a MongoDB database using Docker containers in a very simple way.
