Docker Machine - 容器相关

##Docker Machine安装
	curl -L https://github.com/docker/machine/releases/download/v0.16.2/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine
    chmod +x /tmp/docker-machine
    sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

##查看版本确认是否安装成功
	docker-machine -v

##支持命令

##使用
>192.168.31.43  安装docker machine的机器  主机名：operation
192.168.31.188  被管理的机器       主机名：client1

>##创建步骤：
###1.[配置SSH免密登陆](http://baodoc.frp.bao-server.club:22080/project/19/77/ "配置SSH免密登陆")
###2.执行docker-macine ls查看当前的machine
	#[root@operation ~]# docker-machine ls
	NAME   ACTIVE   DRIVER   STATE   URL   SWARM   DOCKER   ERRORS
###3.创建第一个machine：docker188-192.168.31.188  
	#[root@operation ~]# docker-machine create --driver generic --generic-ip-address=192.168.31.188 docker188
	Running pre-create checks...
	Creating machine...
	(docker188) No SSH key specified. Assuming an existing key at the default location.
	Waiting for machine to be running, this may take a few minutes...
	Detecting operating system of created instance...
	Waiting for SSH to be available...
	Detecting the provisioner...
	Provisioning with centos...
	Copying certs to the local machine directory...
	Copying certs to the remote machine...
	Setting Docker configuration on the remote daemon...
	Checking connection to Docker...
	Docker is up and running!
	To see how to connect your Docker Client to the Docker 	Engine running on this virtual machine, run: docker-machine env docker188
	#注意：这里会出现Error creating machine: Error running provisioning: error installing docker:  这样的错误 原因就是因为网络的原因，没有安装docker

###激活
	# active命令
	[root@operation ~]# docker-machine ls
	NAME        ACTIVE   DRIVER    STATE     URL                         SWARM   DOCKER        ERRORS
	docker188   -        generic   Running   tcp://192.168.31.188:2376           v18.06.1-ce  
	# 这里看到ACTIVE="-",所以状态是没有被激活

[root@operation ~]# docker-machine env docker188
	export DOCKER_TLS_VERIFY="1"
	export DOCKER_HOST="tcp://192.168.31.188:2376"      #激活主机
	export DOCKER_CERT_PATH="/root/.docker/machine/machines/docker188"
	export DOCKER_MACHINE_NAME="docker188"

#执行激活命令
	[root@operation ~]# export DOCKER_HOST="tcp://192.168.31.188:2376"
	[root@operation ~]# docker-machine ls
	NAME        ACTIVE   DRIVER    STATE     URL                         SWARM   DOCKER        ERRORS
	docker188   *        generic   Running   tcp://192.168.31.188:2376           v18.06.1-ce  
	
	#查看激活主机
	[root@operation ~]# docker-machine active
	docker188
