Vagrant：boot2docker：无法在本地找到图像“drupal”

Question

我尝试在 Vagrant box boot2docker（在 Windows 8.1 上）中将 Drupal 作为 Docker 容器运行。

Vagrantfile（Drupal 容器）

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

Vagrant.configure(2) do |config|
  config.vm.provider "docker" do |docker|
    docker.vagrant_vagrantfile = "host/Vagrantfile"
    docker.image = "drupal"
    docker.ports = ['80:80']
    docker.name = 'drupal-container'
  end
  config.vm.synced_folder ".", "/vagrant", type: "smb", disabled: true
end

主机/Vagrantfile (boot2docker)

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

Vagrant.configure(2) do |config|
  config.vm.box = "mitchellh/boot2docker"
  config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.provision "docker"
  config.vm.hostname = "docker-host"
end

在我的 Drupal 容器目录中运行 vagrant up 会导致错误，因为找不到“drupal”图像。

Stdout:

如果我将主机的框更改为ubuntu/trusty64，它可以工作

host/Vagrantfile (ubuntu/trusty64)

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

Vagrant.configure(2) do |config|
  config.vm.box = "ubuntu/trusty64"
  config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.provision "docker"
  config.vm.hostname = "docker-host"
end

但我喜欢用boot2docker，因为它更轻量级。

我的 vagrant 配置有什么问题？如何让 boot2docker 盒子作为主机工作？

Answer 1

我实际上无法使您的配置正常工作，但我已经测试了mitchellh/boot2docker 框并发现了问题。 docker version 在该框中的输出是：

Client version: 1.2.0
Client API version: 1.14
Go version (client): go1.3.1
Git commit (client): fa7b24f
OS/Arch (client): linux/amd64
Server version: 1.2.0
Server API version: 1.14
Go version (server): go1.3.1
Git commit (server): fa7b24f

这个版本的 docker 已经过时了，现在根本无法从 docker hub 拉取镜像。您可以在此处查看 docker 团队宣布弃用的位置：https://blog.docker.com/2015/10/docker-hub-deprecation-1-5/

目前您必须拥有 docker >= 1.6 才能从 docker hub 拉取图像。
