Note: This tutorial requires you to run your app locally on your own computer Pre-requisites • • Getting Started The first thing to notice is that you don’t actually need to have Node.js installed on your machine. You can just use Docker and your IDE. In this case we’re going to show you how to use Visual Studio Code.
Since this is for a Node.js project, an official image of Node from Docker Hub should do it quite nicely. Hence, the FROM node:latest line. We then setup an environment variable for our project’s root within the container, that would be ENV PROJECT_ROOT /opt/app. Docker Compose example copies your current directory (including node_modules) to the container. It assumes that your application has a file named.

Change the orientation for a single page within a larger document, making it easy to print a mix of landscape and portrait pages and eliminating the need to keep landscape-oriented pages in a separate file.
We’ve created a simple application which includes an error. You can see the app in the of this repository. You can either clone this repository, or create the files yourself. Make sure they’re all in the same directory. You will need the following files: • app.js • package.json • index.html • Dockerfile • docker-compose.yml app.js defines a simple node app. It serves up index.html, refreshing every 2 seconds with quote from an array. Here’s what it looks like: Let’s take a look at the Dockerfile.
Version: '3' services: web: build:. Command: nodemon --debug=5858 volumes: -.:/code ports: - '8000:8000' - '5858:5858' A few things are going on here: • It defines a service called “web”, which uses the image built from the Dockerfile in the current directory. • It overrides the command specified in the Dockerfile to enable the remote debugging feature built into Node.js. We do that here because when you ship this application’s container image to production, you don’t want the debugger enabled – it’s a development-only override. • It overwrites the application code in the container by mounting the current directory as a volume.

This means that the code inside the running container will update whenever you update the local files on your hard drive. This is very useful, as it means you don’t have to rebuild the image every time you make a change to the application. • It maps port 8000 inside the container to port 8000 on localhost, so you can actually visit the application. • Finally, it maps port 5858 inside the container to the same port on localhost, so you can connect to the remote debugger. Run the app Using your terminal, navigate to the directory with the app files and start up the app.

It’s undoubtedly beautiful, but the problem is obvious: we’re outputting a blank message at the end before cycling back to the first line. It’s time to debug. Start debugging Open up the app directory in VSCode. Head over to the debugger by clicking the bug icon in the left-hand sidebar.
Create a boilerplate debugger config by clicking the gear icon and selecting “Node.js” in the dropdown. A JSON file will be created and displayed. Replace its contents with the following.
Containers are the best way to deploy Node.js applications to production. Containers provide a wide variety of benefits, from having the same environment in production and development to streamlining deploys for speed and size. Dockerizing your Node.js apps is awesome - but are you doing everything to make the process as reliable and vigorous as possible? If you're deploying to production with Docker, we've made this list of 8 protips that will help improve your life both in development and production.
Quickstart: What Does a Basic Dockerfile Setup Look Like? If you’ve used Docker before, skip down to! Here’s a quick Dockerfile to get up and running.
FROM nodesource/node:4 RUN mkdir -p /home/nodejs/app WORKDIR /home/nodejs/app COPY. /home/nodejs/app RUN npm install --production CMD ['node', 'index.js'] What's going on in this Dockerfile? FROM nodesource/node:4 This file starts by sourcing it’s from the offically supported and maintained. The specific image we are “pinning” to in this example comes from NodeSource, and provides our Docker image with the latest release in the v4 LTS branch of Node.js when building. RUN mkdir -p /home/nodejs/app WORKDIR /home/nodejs/app Next, the Dockerfile creates a directory where we can place the source code for our Node.js application. Is essentially a cd in the Dockerfile, from that line forward all commands will be executed in the context of our newly created directory. /home/nodejs/app Now that the Dockerfile has the directory, this line takes all the files in our and places them inside of our Docker image - in this specific case, think of the build context as the directory the Dockerfile lives in.
