docker machine

环境

docker-machine主机：192.168.1.9  

docker主机：192.168.1.10  

步骤：

安装docker-machine

 

[root@master ~]# curl -L https://github.com/docker/machine/releases/download/v0.14.0/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

[root@master ~]# chmod +x /tmp/docker-machine 
[root@master ~]# cp /tmp/docker-machine /usr/local/bin/docker-machine
[root@master ~]# ll /usr/local/bin/docker-machine 
-rwxr-xr-x 1 root root 28034848 6月  12 15:24 /usr/local/bin/docker-machine
[root@master ~]# docker-machine -v
docker-machine version 0.14.0, build 89b8332

创建ssh密钥对，实现两主机无密登录

[root@node1 ~]# ssh-keygen

[root@node1 ~]# ssh-copy-id 192.168.1.10

创建docker主机,命名host1

[root@node1 ~]# docker-machine create  -d  generic  --generic-ip-address=192.168.1.10  host1

[root@node1 ~]# docker-machine ls

host1   -        generic   Running   tcp://192.168.1.10:2376      v17.12.1-ce   

变更docker环境变量

[root@node1 ~]# docker-machine env host1

export DOCKER_TLS_VERIFY="1"

export DOCKER_HOST="tcp://192.168.1.10:2376"

export DOCKER_CERT_PATH="/root/.docker/machine/machines/host1"

export DOCKER_MACHINE_NAME="host1"

# Run this command to configure your shell:

# eval $(docker-machine env host1)

[root@node1 ~]# eval $(docker-machine env host1)

运行容器查看两端是否同步

[root@node1 ~]# docker run -d busybox

[root@node1 ~]# docker-machine ssh host1

[root@host1 ~]# docker image ls
