Docker machine（Docker 虚拟机）

安装docker

[root@lianxi ~]# yum -y install  docker

启动docker

[root@lianxi ~]# systemctl start docker

下载Docker Machine二进制文件并将其解压缩到PATH

[root@lianxi ~]# curl -L https://github.com/docker/machine/releases/download/v0.12.2/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine &&
chmod +x /tmp/docker-machine &&
sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

检查安装版本

 [root@lianxi ~]# docker-machine version
 docker-machine version 0.12.2, build 9371605

创建一台虚拟机

命令

docker-machine create -d virtualbox VMname

如果遇到以下问题

[root@lianxi ~]# docker-machine create -d virtualbox VMname
Creating CA: /root/.docker/machine/certs/ca.pem
Creating client certificate: /root/.docker/machine/certs/cert.pem
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed
and VBoxManage is in the path"

安装依赖并安装 VirtualBox

[root@lianxi ~]# yum -y localinstall VirtualBox-5.1-5.1.20_114628_el7-1.x86_64.rpm 

再次创建

[root@lianxi ~]# docker-machine create -d virtualbox VMname

查看新建的机器

[root@lianxi ~]# docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKERORS
default   -        VMname   Running   tcp://192.168.99.100:2376           v17.0

获取新虚拟机的环境信息

[root@lianxi ~]# docker-machine env VMname
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/root/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell: 
# eval $(docker-machine env default)

将宿主机的环境变量导入到创建的虚拟机当中

[root@lianxi ~]# eval $(docker-machine env VMname)

查看虚拟机IP

[root@lianxi ~]# docker-machine ip VMname

查看全部虚拟机和IP

[root@lianxi ~]# docker-machine ls

进入到新创建的虚拟机

[root@lianxi ~]# docker-machine ssh VMname

下载Nginx 镜像

docker@VMname:~$ docker pull nginx

安装Nginx

docker@VMname:~$ docker run -d -p 8000:80 --name nginx01 nginx

也可以在虚拟机外安装Nginx

[root@lianxi ~]# docker-machine ssh VMnaem docker pull nginx
[root@lianxi ~]# docker-machine ssh VMname run -d -p 8000:80 --name nginx01 nginx

访问nginx

[root@lianxi ~]# docker-machine ssh VMname curl -I 192.168.99.101:8000
