Vagrant ssh 到 Docker 容器
Vagrant ssh to Docker container
I 运行 Drupal 作为 Vagrant box boot2docker 中的 Docker 容器（在 Windows 8.1 上）：
Vagrantfile（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
host/Vagrantfile（主机）
# -*- 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
我只是在我的 Docker 容器的目录中调用 vagrant up 到 运行 它（和主机）：
$ vagrant up

An error occurred during installation of VirtualBox Guest Additions 5.0.20. Some functionality may not work as intended.
In most cases it is OK that the "Window System drivers" installation failed.
default: Setting hostname...
==> default: Warning: When using a remote Docker host, forwarded ports will NOT be

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？
我也试过用环境的hash。我通过
确定哈希
$ 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.
如果我将 docker.has_ssh = true 添加到 Vagrantfile （我不知道我是否需要它，因为我可以在没有它的情况下调用 vagrant ssh）：
# -*- 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
那么我无法 run/reload 我的容器，因为它会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？
注意：我可以先连接主机，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.

但这是一个不切实际的解决方法。我只是喜欢在容器的目录下调用vagrant ssh来连接容器（常见的Vagrant工作流）
你 运行 一个 docker 容器而不是一个 VM 作为你的提供者，所以流浪工作流被打破，因为你不能 ssh 进入 docker 容器。
当您使用 docker 提供程序时，您可以 运行 您的命令使用 vagrant docker-run；查看 doc
如果您直接 运行ning docker，您将无法直接使用 ssh，有一些 可以解决这个问题，但是 vagrant 作为提供者的抽象不能使它是一个简单的 ssh 命令，它不是官方支持。
