That said, you might be wondering, “What’s Docker Desktop, and how’s it different from the open-source Docker Engine?” One of the best ways to get started with Docker is by installing Docker Desktop - especially if you’re a developer using Mac or Windows.
What can I use Docker for?ĭocker simplifies application development and removes complexities for you and many other developers around the world. Images include everything needed to run an application: code, runtime, system tools, system libraries, and settings. If you’re familiar with object-oriented programming concepts, think of images as classes and containers as objects. To create Docker containers, you’ll first need a Docker image. Currently, the core technology exists as a popular, open-source container runtime called Docker Engine. Since its debut in 2013, Docker has become an industry standard. Though the technology behind containers has been around for a while, Docker made it easier to work with containers.
This makes such applications easily portable between machines and solves the “it works on my machine” problem.
A container packages code and all its dependencies into a single unit, thus letting an application run quickly and reliably from one computing environment to another. What is Docker?īefore talking about Docker, let’s take a moment to highlight containers. This blog introduces Docker technology, Docker Desktop, and why you should care about both. While Docker is technical at its core, our goal is to make our tools approachable for all users regardless of their familiarity with containers.
To troubleshoot the installation as well as learn how to customize the build ( more RAM, more/less disk space, macOS version etc ) check out the project page here.If you’re curious about Docker but haven’t used it, you’re at the right place. That’s it finish setting up macOS Catalina and enjoy running macOS in a Docker container on your Linux machine. When the installation is finished, upon reboot select macOS to boot into macOS Catalinaġ2. On restart, select macOS to continue the installation.ġ1. Exit Disk Utility and and select Reinstall macOSġ0. Select Disk Utility and format the largest disk in the list.ĩ. Run docker run -privileged -e "DISPLAY=$" -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osxĨ. Now pull the image with docker pull sickcodes/docker-osxĦ.
For other distros as well as how to install Docker on macOS and Windows, check out the official installation guide here. This is not a Docker tutorial, but let’s have a quick look at how to install it on Arch linux ( more info for Docker on Arch here ).
