Docker Engine和Docker Machine 到底有什么区别?

When people say “Docker” they typically mean Docker Engine, the client-server application made up of the Docker daemon, a REST API that specifies interfaces for interacting with the daemon, and a command line interface (CLI) client that
talks to the daemon (through the REST API wrapper). Docker Engine accepts
docker
commands from the CLI, such as docker run ,
docker ps to list running containers,
docker images
to list images, and so on.

一般当人们说 “Docker”时, 他们一般指的是Docker Engine, 一个client-server 结构的应用, 包含Docker daemon,一个 用来和daemon 交互的REST API, 一个命令行应用CLI。 Docker Engine 在命令行中接收并解析、执行docker 命令, 例如: docker run , docker ps等。

Docker Engine和Docker Machine 到底有什么区别?

Docker Machine is a tool for provisioning and managing your Dockerized hosts (hosts with Docker Engine on them). Typically, you install Docker Machine on your local system. Docker Machine has its own command line client
docker-machine and the Docker Engine client,
docker. You can use Machine to install Docker Engine on one or more virtual systems. These virtual systems can be local (as when you use Machine to install and run Docker Engine in VirtualBox on Mac or Windows) or remote
(as when you use Machine to provision Dockerized hosts on cloud providers). The Dockerized hosts themselves can be thought of, and are sometimes referred to as, managed “machines”.

Docker Machine 是一个创建和管理Docker Hosts 的工具。
