Docker - Windows中使用vagrant+virtual box创建Docker

一、安装Vagrant

访问vagrant官网Vagrant
下载对应系统的Vagrant
安装
命令行输入vagrant，测试是否安装成功

二、安装Virtual Box

访问virtualbox官网Virtual Box
选择左侧的downloads
选择下载对应的操作系统版本
安装
[win10中若出现]安装virtualbox快完成时立即回滚，并提示安装出现严重错误
(1)打开服务
(2)找到Device Install Service和Device Setup Manager，然后启动
(3)再次尝试安装

三、安装Centos7

创建first-docker-centos7文件夹，并进入其中[目录路径中不要有中文字符]
在此目录下打开cmd，运行vagrant init centos/7 此时会在当前目录下生成Vagrantfile
运行vagrant up [注意不要运行，拉取远端的centos7太慢] 此时会找centos7的镜像，本地有就用本地的，本地没有就会拉取远端的
准备centos7的box
a. 下载centos box Centos7
b. 将下载好的文件放到指定目录
c. 运行vagrant box add centos/7 D:\迅雷下载\virtualbox.box
d. vagrant box list 查看本地的box[这时候可以看到centos/7]
在first-docker-centos7文件夹下创建Vagrantfile文件，文件内容如下：

# -*- mode: ruby -*-
# vi: set ft=ruby :

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
 # The most common configuration options are documented and commented below.
 # For a complete reference, please see the online documentation at
 # https://docs.vagrantup.com.

 # Every Vagrant development environment requires a box. You can search for
 # boxes at https://vagrantcloud.com/search.
 config.vm.box = "centos/7"

 # Disable automatic box update checking. If you disable this, then
 # boxes will only be checked for updates when the user runs
 # `vagrant box outdated`. This is not recommended.
 # config.vm.box_check_update = false

 # Create a forwarded port mapping which allows access to a specific port
 # within the machine from a port on the host machine. In the example below,
 # accessing "localhost:8080" will access port 80 on the guest machine.
 # NOTE: This will enable public access to the opened port
 # config.vm.network "forwarded_port", guest: 80, host: 8080

 # Create a forwarded port mapping which allows access to a specific port
 # within the machine from a port on the host machine and only allow access
 # via 127.0.0.1 to disable public access
 # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

 # Create a private network, which allows host-only access to the machine
 # using a specific IP.
 # config.vm.network "private_network", ip: "192.168.33.10"

 # Create a public network, which generally matched to bridged network.
 # Bridged networks make the machine appear as another physical device on
 # your network.
  config.vm.network "public_network"

 # Share an additional folder to the guest VM. The first argument is
 # the path on the host to the actual folder. The second argument is
 # the path on the guest to mount the folder. And the optional third
 # argument is a set of non-required options.
 # config.vm.synced_folder "../data", "/vagrant_data"

 # Provider-specific configuration so you can fine-tune various
 # backing providers for Vagrant. These expose provider-specific options.
 # Example for VirtualBox:
 #
 config.vm.provider "virtualbox" do |vb|
       vb.memory = "3000"
       vb.name= "my-centos7"
       vb.cpus= 2
   end
 #
 # View the documentation for the provider you are using for more
 # information on available options.

 # Enable provisioning with a shell script. Additional provisioners such as
 # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
 # documentation for more information about their specific syntax and use.
 # config.vm.provision "shell", inline: <<-SHELL
 #   apt-get update
 #   apt-get install -y apache2
 # SHELL
end

根据本地的centos7 box创建虚拟机：
vagrant up[打开virtual box，可以发现centos7创建成功]
vagrant基本操作
(1)vagrant ssh 进入刚才创建的centos7中
(2)vagrant status 查看centos7的状态
(3)vagrant halt 停止centos7
(4)vagrant destroy 删除centos7
(5)vagrant status 查看当前vagrant创建的虚拟机
(6)Vagrantfile中也可以写脚本命令，使得centos7更加丰富但是要注意，修改了Vagrantfile，要想使正常运行的centos7生效，必须使用vagrant reload
至此，使用vagrant+virtualbox搭建centos7完成，后面可以修改Vagrantfile对虚拟机进行相应配置
通过vagrant ssh可以进入虚拟机：
通过ip a命令查看当前虚拟机的IP地址：
修改root账号的password:
vi /etc/ssh/sshd_config 修改PasswordAuthentication yes
systemctl restart sshd
现在就可以通过root账号登陆虚拟机了

四、box的打包分发

退出虚拟机 vagrant halt
打包 vagrant package --output first-docker-centos7.box
得到first-docker-centos7.box
将first-docker-centos7.box添加到其他的vagrant环境中 vagrant box add first-docker-centos7 first-docker-centos7.box
得到Vagrantfile vagrant init first-docker-centos7
根据Vagrantfile启动虚拟机 vagrant up [此时可以得到和之前一模一样的环境，但是网络要重新配置]

五、安装docker

进入centos7 虚拟机
卸载之前的docker

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

在这里插入图片描述
3. 安装必要的依赖

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

设置docker仓库

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

添加阿里云镜像阿里云镜像

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://ns2jtf98.mirror.aliyuncs.com"]
}
EOF

安装docker

sudo yum install -y docker-ce docker-ce-cli containerd.io

启动docker

sudo systemctl start docker && sudo systemctl enable docker

测试docker是否安装成功

sudo docker run hello-world
