Vagrant docker提供者:创建并启动vs运行

Question

我是流浪汉的新手，在Windows 7上使用1.7.4和VirtualBox 5.0.10，并试图弄清楚如何按照我想要的方式设置和运行docker容器，如下所示：

1. 启动我的docker主机，它已经配备了最新的docker工具，并在启动cadvisor容器的情况下启动-我从公开可用的williamyeh/ubuntu-trusty64-docker获得此框
2. 如果（例如）我想使用的mongo容器还没有在docker主机上创建，只需创建它（不要启动它）
3. 否则，如果容器已经存在，请启动它（不要尝试创建它）

在我目前的设置中，使用docker提供程序，在第一次使用vagrant up后，使用vagrant halt和vagrant up将产生以下错误：

Bringing machine 'default' up with 'docker' provider...
==> default: Docker host is required. One will be created if necessary...
    default: Docker host VM is already ready.
==> default: Warning: When using a remote Docker host, forwarded ports will NOT be
==> default: immediately available on your machine. They will still be forwarded on
==> default: the remote machine, however, so if you have a way to access the remote
==> default: machine, then you should be able to access those ports there. This is
==> default: not an error, it is only an informational message.
==> default: Creating the container...
    default:   Name: mongo-container
    default:  Image: mongo
    default:   Port: 27017:27017
A Docker command executed by Vagrant didn't complete successfully!
The command run along with the output from the command is shown
below.
Command: "docker" "run" "--name" "mongo-container" "-d" "-p" "27017:27017" "-d" "mongo"
Stderr: Error response from daemon: Conflict. The name "mongo-container" is already in use by container 7a436a4a3422. You have to remove (or rename) that container to be able to reuse that name.

这是我用于docker主机的Vagrantfile：

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.require_version ">= 1.6.0"
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.hostname = "docker-host"
  config.vm.box_check_update = false
  config.ssh.insert_key = false
  config.vm.box = "williamyeh/ubuntu-trusty64-docker"
  config.vm.network "forwarded_port", guest: 27017, host: 27017
  config.vm.synced_folder ".", "/vagrant", disabled: true
end

这里是docker提供商Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.require_version ">= 1.6.0"
VAGRANTFILE_API_VERSION = "2"
ENV['VAGRANT_DEFAULT_PROVIDER'] = 'docker'
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.synced_folder ".", "/vagrant", disabled: true
  config.vm.provider "docker" do |docker|
    docker.vagrant_vagrantfile = "../docker-host/Vagrantfile"
    docker.image = "mongo"
    docker.ports = ['27017:27017']
    docker.name = 'mongo-container'
  end
end

Answer 1

嗯，我不确定我的环境中发生了什么，但在重新配置设置时，我删除并恢复了我的基本docker主机映像，从那时起，docker提供程序上的vagrant up、vagrant halt和vagrant up的工作方式与我预期的完全一样。

无论如何，我想这个问题已经得到了vagrant的支持。
