drupal - Vagrant ssh 到 Docker 容器

Question

我在 Vagrant box boot2docker(在 Windows 8.1 上)中将 Drupal 作为 Docker 容器运行:

Vagrant 文件 (我的 Docker 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/Vagrant 文件 (主持人)

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

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

我只需调用 vagrant up在我的 Docker 容器的目录中运行它(和主机):

$ vagrant up

    default: Vagrant will now create or start a local VM to act as the Docker

    default:
    default: Container created: d12499a52f3d3f27
==> default: Starting container...
==> default: Provisioners will not be run since container doesn't support SSH.

现在我喜欢从同一目录连接到容器:

$ vagrant ssh
==> default: SSH will be proxied through the Docker virtual machine since we're
==> default: not running Docker natively. This is just a notice, and not an error.
==> default: The machine you're attempting to SSH into is configured to use
==> default: password-based authentication. Vagrant can't script entering the
==> default: password for you. If you're prompted for a password, please enter
==> default: the same password you have configured in the Vagrantfile.
docker@127.0.0.1's password: tcuser
ssh: connect to host 172.17.0.1 port 22: Connection refused
Connection to 127.0.0.1 closed.

为什么连接被拒绝？密码错误？

我还使用环境的哈希进行了尝试。我确定了哈希

$ vagrant global-status
id       name    provider   state   directory
----------------------------------------------------------------------------------------------
e4da5ae  default virtualbox running c:/my-project-path/host/boot2docker
98ef037  default docker     running c:/my-project-path

The above shows information about all known Vagrant environments
on this machine. This data is cached and may not be completely
up-to-date. To interact with any of the machines, you can go to
that directory and run Vagrant, or you can use the ID directly
with Vagrant commands from any directory. For example:
"vagrant destroy 1a2b3c4d"

并尝试连接(同样的错误):

$ vagrant ssh 98ef037
==> default: SSH will be proxied through the Docker virtual machine since we're
==> default: not running Docker natively. This is just a notice, and not an error.
==> default: The machine you're attempting to SSH into is configured to use
==> default: password-based authentication. Vagrant can't script entering the
==> default: password for you. If you're prompted for a password, please enter
==> default: the same password you have configured in the Vagrantfile.
docker@127.0.0.1's password: tcuser
ssh: connect to host 172.17.0.3 port 22: Connection refused
Connection to 127.0.0.1 closed.

如果我添加 docker.has_ssh = true到 Vagrantfile (我很困惑是否需要它，因为我可以调用 vagrant ssh 没有它):

# -*- 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'
    docker.has_ssh = true
  end
  config.vm.synced_folder ".", "/vagrant", type: "smb", disabled: true
end

然后我无法运行/重新加载我的容器，因为它无限期地等待机器启动:

$ vagrant reload
==> default: Stopping container...
==> default: Starting container...
==> default: Waiting for machine to boot. This may take a few minutes...
Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

那么如何使用 vagrant ssh 连接到我的 Docker 容器？ ?

注:我可以先连接到主机，然后在上面调用docker

$ cd host
$ vagrant ssh
==> default: The machine you're attempting to SSH into is configured to use
==> default: password-based authentication. Vagrant can't script entering the
==> default: password for you. If you're prompted for a password, please enter
==> default: the same password you have configured in the Vagrantfile.
docker@127.0.0.1's password: tcuser
                        ##         .
                  ## ## ##        ==

但这是一个不切实际的解决方法。我只是喜欢调用 vagrant ssh在容器的目录下连接容器(常见的 Vagrant 工作流)。

Answer 1

您运行 docker 容器而不是虚拟机作为您的提供者，因此 vagrant 工作流程被破坏，因为您无法 ssh 进入 docker 容器。

当您使用 docker 提供程序时，您可以使用 vagrant docker-run 运行您的命令。 ;见doc

如果你直接运行docker，你将无法直接ssh，有一些hacks解决这个问题，但是作为提供者的抽象的 vagrant 不能使它成为一个简单的 ssh命令及其不是官方支持。
