Under Linux, there’s a command called ifconfig that does just that let’s try it: command not found: ifconfig If it does, it means some basic commands are working. Once the installation is completed, we can check if it is working by executing inside the NodeOS shell the command ls. Run bash npm start to run NodeOS inside Qemu.Yes, it will take that much time, so do something interesting in the meantime. I am going to quote, word by word, the official documentation: “Pick some microwave popcorn and go to see a movie.Download the project source code: bash git clone Compile it by running following commands: cd NodeOS and npm install.Once you have everything, you can proceed with the source code compilation: The Linux build utilities (make, g++, gcc, autoconf).You can compile it on OS X, but it will take longer since it has to make a cross compilation. That’s not too difficult, but it takes a long time. So, if you want to use the latest version you should definitely get the source code. At the time of writing, the last change to the Docker image of NodeOS was performed two months ago, while the development version was updated six days ago. There are some reasons why you would want to avoid using Docker, and one being the latest NodeOS version. ![]() Once the installation is completed, it opens an SSH session to the NodeOS shell. When you run the aforementioned command, Docker automatically downloads the disk image for NodeOS from a repository and performs the installation of NodeOS inside a virtual machine. All you need to do is execute the following command, and Docker does all the magic: sudo docker run -t -i nodeos/nodeos Once you installed Docker, running an instance of NodeOS is easy. It might work with Windows, but I did not try it. A computer with either Mac OSX or Linux.The easiest and quickest way to try out NodeOS is by using the following: So, how can I try out NodeOS? Using Docker Sure, you can implement some of the missing features fairly easily using a bit of JavaScript, but the fact all the mentioned features are not available by default, is not good. Furthermore, you cannot run it as a desktop operating system since it has no GUI. For example, the whole BASH toolset is missing, including ps, tail, nano and grep. It’s still missing many key functions for a server operating system. The downsidesĪs much as I would like a finished NodeOS, it is not there, yet. Since NodeOS is based on the Linux kernel, you could run every application written for other Linux distributions with minimal changes. This might not seem like a big deal, but Linux is the most-used server operating system. At the time of writing, there are 210,735 packages since the number of NPM packages grows every minute, it would not be strange if, in a few years, NodeOS has a million applications. If you think about it, an operating system that uses Node.js means that any package available in NPM is, at the same time, also a NodeOS package. The end result is hacker cannot compromise the whole system. Also, it provides a good deal of security if a hacker finds a way to get inside a particular account in the operating system, the only partition that s/he can access is the partition of that user. Since their “home folder” is, in fact, the root of their own filesystem hierarchy, they can install packages globally without requiring special permissions and not need to configure anything since they are installed in their home directory by default. NodeOS introduced an interesting paradigm: If all users have an isolated filesystem, it gives them a simple filesystem hierarchy to work with. Per-user independent and isolated root filesystem Now, think about the same thing happening with an operating system. First of all, think about the progress Node.js has made in the short time it’s been around. ![]()
