The Docker Toolbox installs several components to allow users to run Docker on their Mac systems without running a Linux VM directly. It includes the Docker client, Docker Machine, Docker Compose, Docker Kitematic, and Oracle VirtualBox. Docker Machine is used to create and connect to a lightweight Linux VM hosted by VirtualBox where the Docker daemon runs. This allows users to work with Docker images and containers without having to manage a separate Linux environment.

3. What's in the toolbox
• Docker Client
• Docker Machine
• Docker Compose (Mac only)
• Docker Kitematic
• VirtualBox
Because the Docker daemon uses Linux-specific kernel features, you can’t run Docker natively in OS X.
Instead, you must use docker-machine to create and attach to a virtual machine (VM).
This machine is a Linux VM that hosts Docker for you on your Mac.
Docker daemon이 Linux에서만 돌릴수 있기 때문에 Linux VM 이 꼭 필요!!

4. In an OS X installation, the docker daemon is running inside a Linux VM called default.
The default is a lightweight Linux VM made specifically to run the Docker daemon on Mac OS X.
The VM runs completely from RAM, is a small ~24MB download, and boots in approximately 5s.

8. The Virtual Box

9. The Docker Client
The Docker client, in the form of the docker binary, is the primary user interface to Docker.
It accepts commands from the user and communicates back and forth with a Docker daemon.

10. Kitematic
Kitematic, the Docker GUI, runs on Mac OS X and Windows operating systems.

11. Overview of Docker Compose
Compose is a tool for defining and running multi-container applications with Docker.
With Compose, you define a multi-container application in a single file, then spin your
application up in a single command which does everything that needs to be done to
get it running.
• Start, stop and rebuild services
• View the status of running services
• Stream the log output of running services
• Run a one-off command on a service
Compose has commands for managing the whole lifecycle of your application:

12. Overview of Docker Compose
1. Define services that make up your app in docker-compose.yml
2. $ docker-compose up
docker-compose.yml

13. The Docker Machine
To create a virtual machine, you supply Docker Machine with the name of the driver you want use. The driver represents the virtual
environment. For example, on a local Linux, Mac, or Windows system the driver is typically Oracle Virtual Box. For cloud providers,
Docker Machine supports drivers such as AWS, Microsoft Azure, Digital Ocean and many more. The Docker Machine reference
includes a complete list of the supported drivers.

15. The Docker Machine
•start, inspect, stop, and restart a host
•upgrade the Docker client and daemon
•configure a Docker client to talk to your host
Once you create one or more Docker hosts, Docker Machine supplies a number of commands for
managing them. Using these commands you can

17. The Docker Quickstart Terminal

18. I’ve recently been tinkering with Docker, after seeing how popular it’s become and I’m convinced
it’s the future of infrastructure and development. By removing the virtual machine operating
system layer, it makes it a lot easier to move around apps and their data.
It’s good to see Docker Toolbox, as I had indeed found getting started in the past was a little
painful and confusing.
Docker Toolbox is an installer that helps pull together the various components of the platform
for local development. It installs the Docker client, Compose, Kinematic, Machine and VirtualBox
so you don’t need to install them separately.
