If we're running a non-Linux OS, we need a Linux VM to run Docker. It relies on Oracle Virtualbox to provide a hypervisor. Docker Machine is an older alternative for macOS and Windows.

Hyper-V is free to install for any Windows Pro or Windows Server installation. Docker for Windows requires Microsoft Hyper-V.Hyperkit is included out of the box with Docker for Mac, so no additional installation is required.
Hyperkit is an embedded, open source hypervisor. Docker provides this virtual machine differently on each non-Linux OS it supports: In order to provide a Linux kernel on macOS and Windows, we need a virtual machine. The answer is "yes!" But there's a condition. Can Docker still run Linux containers here? What happens when we need to run Docker on a host OS that isn't Linux? Most of us run either macOS or Windows. Since a kernel is already on the system, Docker only needs to sandbox any container it runs from the host OS. This approach works great on systems that are running Linux on the bare metal. Instead, it provides a Linux kernel, and lets each container decide what distribution of Linux it needs. The differences in distributions relate to the utilities necessary to create an execution environment for an application.ĭocker doesn't favor one distribution of Linux over another. The kernel provides the core APIs necessary to run a Linux application. Each of these distributions, however, all rely on the same core component - the Linux kernel. Ubuntu, Debian, and Red Hat are just a few. There are many different distributions of Linux. This is perfect for us as most web servers that run Drupal sites in production use the Linux operating system. While Docker can run Windows applications within a container, the vast majority of containers run an application designed for Linux. In many ways, Linux is Docker's native environment. There are lots of hypervisors out there including VMWare, Parallels, Hyper-V, and Oracle VirtualBox.

The guest OS relies on a piece of software on the host called a hypervisor, which runs the virtual machine. Likewise, the host OS allows for the guest OS to run on the bare metal. When you run the party and invite them to your home, you're the host and your friends are the guests. You can think about it like holding a party for your friends. This additional operating system is called the guest OS. When we run a virtual machine on our system, we're running a completely separate operating system on top of the one we installed previously. The host OS supports all the utilities and applications we'll run on that system. When we use a boot disk or a USB stick to install an operating system on bare metal, we're installing the host OS. It's obvious, but no VM or container can exist without bare metal supporting it. When we refer to a computer's physical hardware, devoid of any operating system, we call it the bare metal system. Shortly after flipping the switch the monitor will say that it cannot find the operating system or boot disk. If you've done this before you know that it won't get very far. You've selected each component, assembled them, and then powered it all on. Imagine that you've built a computer yourself. Fortunately, there's some terminology that can help us. Whenever we talk about virtualization or containerization it can be difficult to know if we're talking about the VM, our OS, or the real physical hardware that we're using.

Installing Docker is easy, but there are some details you may want to consider before you download and run the installer.
