A Docker host is either a physical computer system or a virtual machine using Linux as the operating system. Docker host can be your laptop, server or virtual machine in your data center or computing resource provided by any cloud platform.
For a computer to be a Docker host, it needs to be running Linux as the operating system. If the computer or laptop is running other operating systems such as OS X and Windows, then it is required to use a virtual machine that runs Linux.
A Docker host provides these abilities:
- To run processes in isolation from each other
- Granting each controlled access to system resources
- Dedicated network configuration.
