WORKDIR /app This simply establishes a working directory inside your image. In case youвЂ™re wondering, itвЂ™s 907MB on my Mac.

That means we donвЂ™t have to install any framework itвЂ™s already included with this base image. In this case, itвЂ™s the official image from the Node.js and has Node.js version 8.x installed. HereвЂ™s a short, step-by-step breakdown:ДЇROM node:8 This is your base image, the starting point. The file вЂњDockerfileвЂќ is used to guide the construction of your image. The following file, 'Dockerfile', does those things: Finally, we'll give the image a command to be executed when someone runs the image in a container.

We'll then copy our code in the image, then run npm install to make sure the dependencies are up-to-date. We'll start with an OS+Framework combination to keep things simple. Yes, like any IT technology, you can make this as simple or as complicated as you like. You can also do just that - start with an OS and add a framework - and save that image and use it as your base for other images. You can - and there might be good reasons for this - start with the operating system and then install the framework all inside your image as you build it. So it's pretty common to start from that point. The build process is done in layers, with the starting point typically being an operating system or, more likely, an OS and framework combination. We'll create a file called 'Dockerfile' that contains the steps and information needed to build an image. You need the code you're going to run, a file to configure/manage the build process, and the tool (i.e. So, if you are not using podman, simply use the command docker in place of every podman in the following. In fact, you could run alias docker=podman and you'd not know the difference. Because it is safer (it does not require root access), I'm going to use Podman to build and run my container, knowing that the commands used are 100 percent compatible with the docker command. Which method you use to build and run your container is based on your operating system and tool selection. While numerous libraries are available for extending Node's functionalities, the engine comes with a set of core modules implementing basic functionalities.After reading the previous blog post in this series, ' Containers, Kubernetes, microservices: Start here', you're now ready to build your first 'Hello World' application and run it in a container. Node.js is a Javascript engine (Google's V8 engine for Chrome, written in C++) that allows to run Javascript outside the browser. The created server can then be accessed with the URL or in the browser.ДЄ simple web page will appear with a вЂњHello, World!вЂќ text at the top, as shown in the screenshot below. In this case, if we name it hello.js we can run the application by going to the directory the file is in and using the following command: node hello.js Http.createServer((request, response) => ).listen(1337) // 4. const http = require('http') // Loads the http module To create the application, create a file containing theДЇollowing JavaScript code. The http module provides the functionality to create an HTTP server using the http.createServer() method. The http module is a Node.js core module (a module included in Node.js's source, that does not require installing additional resources). Note that, instead of using port 1337, you can use any port number of your choice which is currently not in use by any other service.

In this example we'll create an HTTP server listening on port 1337, which sends Hello, World! to the browser.
