docker-machine(1) 安装管理docker主机
说明
ubuntu 系统类型
test docker、docker-machine管理操作用户
192.168.1.73 docker-machine服务器端
192.168.1.80 docker 客户端
1sudo配置：
执行范围：docker-machine服务器端、docker 客户端
test@bogon:~$ sudo visudo
#追加1行，确保远程ssh执行命令不报错
#sudo: no tty present and no askpass program specified
Defaults visiblepw
#文件末尾追加 sudo无需密码
test ALL=(ALL) NOPASSWD: ALL
二、docker-machine服务器端配置
2.1 分发公钥
生成私钥、公钥方法自行google
scp .ssh/authorized_keys 192.168.1.80:./ssh/
2.2 下载安装
curl -L https://github.com/docker/machine/releases/download/v0.9.0-rc2/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine sudo mv /tmp/docker-machine /usr/local/bin/ sudo chmod a+x /usr/localbin/docker-machine
2.3 创建docker主机
test@bogon:~$ docker-machine create --driver generic --generic-ip-address=192.168.1.80 --generic-ssh-key ~/.ssh/id_rsa --generic-ssh-user=test 80 Running pre-create checks... Creating machine... (80) Importing SSH key... 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 ubuntu(systemd)... Installing Docker... 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 80
docker-machine详细命令参见：https://docs.docker.com/machine/
命令分析：
create #创建docker主机
--driver generic #驱动类型 generic 支持linux通用服务器，还支持很多种云主机
--generic-ip-address=192.168.1.80 #指定主机
--generic-ssh-key ~/.ssh/id_rsa #指定私钥
--generic-ssh-user=test #指定用户
80 #主机名称
查看已创建docker主机
test@bogon:~$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS 73 * generic Running tcp://192.168.1.73:2376 v17.06.0-ce 80 - generic Running tcp://192.168.1.80:2376 v17.06.0-ce
远程执行docker命令，创建docker虚拟机
test@bogon:~$ docker-machine ssh 80 docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 691bd1e50cd2 hello-world "/hello" 2 days ago Exited (0) 2 days ago tender_banach test@bogon:~$ docker-machine ssh 80 docker run hello-world test@bogon:~$ docker-machine ssh 80 docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 68399de0b83b hello-world "/hello" 5 seconds ago Exited (0) 4 seconds ago thirsty_bohr 691bd1e50cd2 hello-world "/hello" 2 days ago Exited (0) 2 days ago tender_banach
也可通过切换环境变量，来实现：
test@bogon:~$ eval $(docker-machine env 80) test@bogon:~$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS 73 - generic Running tcp://192.168.1.73:2376 v17.06.0-ce 80 * generic Running tcp://192.168.1.80:2376 v17.06.0-ce test@bogon:~$ docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
68399de0b83b hello-world "/hello" 5 seconds ago Exited (0) 4 seconds ago thirsty_bohr
691bd1e50cd2 hello-world "/hello" 2 days ago Exited (0) 2 days ago tender_banach
