docker-machine 是docker官方提供的docker管理工具。
通过docker-machine可以轻松的做到：

1. Docker Centos 7 Ssh Server
2. Docker Centos7 Start Sshd
3. Docker Centos 7 Sshd
4. Docker Centos 7 Ssh Key
5. Docker Centos 7 Ssh Install

Docker centOS 7 based with systemd enabled and sshd installed. In order to connect in the running container using ssh, obtain containerid running docker ps and run. How to Install Docker on CentOS 7 & RHEL 7 By Rahul February 29, 2016 3 Mins Read Updated: December 13, 2019 Docker is container-based application framework, which wrap of a specific application with all its dependencies in a container.

在Windows平台和MAC平台安装和运行docker

Docker Centos 7 Ssh Server

搭建和管理多个docker 主机

搭建swarm集群

环境win下面安装的virtualbox，virtualbox安装的centos7，网络模式NAT+hostonly

ip：192.168.56.102（hostonly）

1、安装docker-machine：

2、查看docker-machine版本：

3、在centos7环境下创建machine：

但是却报错了，以为virtualbox安装的centos7环境支持的是virtualbox驱动，才发现环境安装支持virtualbox驱动

Docker Centos7 Start Sshd

于是采用generic驱动，具体介绍查看官网：https://docs.docker.com/machine/drivers/generic/

将密码发给自己，然后重新继续创建machine：

于是终于创建machine成功了

利用ssh登录到machine中：

执行环境变量，进入到machine环境：

可以看见在192.168.101.14环境上为远程主机192.168.56.102创建的machine

现在查看远程主机是否创建了容器：

报错原因：

可以发现，为远程主机创建容器成功

可以看见两主机的镜像同步，也是容器也是同步的

执行上面将machine的环境变量取消就可以返回原来的环境了：

而如果需要返回machine环境就继续执行machine环境变量就行，这种方式很好的隔离了本地和远程镜像和容器

Docker is container-based application framework, which wrap of a specific application with all its dependencies in a container. Docker containers can easily to ship to a remote location on start there without making entire application setup. This tutorial will help you to install and manage Docker on CentOS/RHEL 7/6 operating system.

Step 1 – Verify Requirements

For a standard installation, Docker required 64-bit operating system having Kernel >= 3.10 version. Older versions of Kernel have some missing requirements to run all features of Docker.

Also install the following packages on your system.

Step 2 – Add Docker Yum Repository

Let’s add the official Docker yum repository on your system.

Step 3 – Install Docker on CentOS 7

Docker Centos 7 Sshd

After adding the yum repository to your CentOS system, update the yum cache by executing the following command.

Now install docker community edition package to install docker on your system. This is installed many of required decencies on your system.

After successful installation of Docker engine, Let’s start the docker service.

Then check the status of the Docker service.

Docker has been installed and running on your system. You can visit our Docker tutorial section to work with Docker containers.

How to Use Docker?

Search Docker Images

First of all search Docker container images from Docker hub. For example, below command will search all images with Ubuntu and list as output

Download Docker Images

Now download the Docker container with name Ubuntu on your local system using following commands.

Now make sure that above images have been downloaded successfully on your system. Below command list all images.

Launch New Container with Image

Finally, launch a Docker container using the above-downloaded image on your system. Below command will start a new container and provide you access to that container with /bin/bash shell.

To exit from docker container type CTRL + P + Q. This will leave container running in the background an provide you host system console. If you used exit command, it will stop the current container.

After exiting from Docker container, execute below command to list all running containers.

By default Above command will list only running containers. To list all containers (including stopped container) use the following command.

Start/Stop/Attach Container

You can start, stop or attach to any containers with following commands. To start container use following command.

Docker Centos 7 Ssh Key

To stop container use following command.

Docker Centos 7 Ssh Install

To attach to currently running container use following command.
