我想创建几个预安装了

docker

的虚拟机

最好的/推荐的方法是什么

a）让Docker provisioner做一些虚拟的事情，只是为了安装Docker，例如

  mymachine.vm.provision "docker" do |docknode|
      # do something pointless
  end

b）通过shell provisioner脚本运行docker安装

mymachine.vm.provision "shell", path: "docker-installation-script.sh"

c）使用预安装的Docker附带的流浪映像？

我将其用作“您可以使用机器在本地Mac或Windows box、公司网络、数据中心或Azure、AWS或Digital Ocean等云提供商上创建Docker主机”。使用Docker启动虚拟机是一种简单快捷的方法。

官方说明如下：

例如：

Vagrant.configure("2") do |config|
  config.vm.provision "docker" do |d|
    d.build_image "/vagrant/app"
  end
end

或

我也在寻找这个问题的答案，在StackOverflow上找到了答案。看来你是对的。运行虚拟映像是安装最新版本DOCKER的最佳方式

  config.vm.provision "docker" do |d|
      d.run "hello-world"
  end

From：如果您想安装特定版本的docker，您必须在docker provisioner（provisioners按顺序运行）之前运行shell provisioner来安装特定版本的docker。

如果您使用的是具有支持的最新Vagrant（例如，下面的步骤是使用2.2.6测试的），然后，您可以使用非常简单的一个或两个一行程序安装Docker，而无需：

运行

vagrant provision

或

vagrant up

并观察此输出：

==> default: Running provisioner: docker...
    default: Installing Docker onto machine...
==> default: Running provisioner: docker_compose...
    default: Checking for Docker Compose installation...
    default: Getting machine and kernel name from guest machine...
    default: Downloading Docker Compose 1.24.1 for Linux x86_64

    default: Installing Docker Compose 1.24.1 in guest machine...
    default: Symlinking Docker Compose 1.24.1 in guest machine...

最后，

vagrant ssh

连接到VM并检查已部署Docker基础架构的版本：

这里有一个更加用户友好的

Vagrant文件

（在Vagrant 2.2.7上测试）

Vagrant.configure（“2”）do | config|
config.vm.box=“ubuntu/bionic64”
#需要插件https://github.com/leighmcculloch/vagrant-docker-compose
config.vagrant.plugins=“vagrant docker compose”
#安装docker和docker compose
config.vm.provision:docker
config.vm.provision:docker_compose
config.vm.provider“virtualbox”do | vb|
vb.customize[“modifyvm”，：id，“--ioapic”，“on”]
vb.customize[“modifyvm”，：id，“--memory”，“2048”]
vb.customize[“modifyvm”，：id，“--cpu”，“2”]
结束
结束

如上所述，您可以从

Vagrantfile

下面是步骤

我认为（b）是最好的部署方式，通过这种方式，您可以知道在部署过程中会发生什么。这意味着，当发现bug或您想要的某些功能时，您可以解决所有问题

有一天，也许您需要将docker部署到另一个地方，脚本将对您有很大帮助。

使用boot2docker或vagrant是非常必要的
