Ruby docker-api来挂载卷

Question

如何在运行时使用ruby docker-api（https://github.com/swipely/docker-api）将主机卷挂载到docker中？

基本上，docker run -v path:path功能与这个宝石。

Answer 1

在其README.md为docker-api gem状态本文档：

require 'docker' 

# Create a Container. 
container = Docker::Container.create('Cmd' => ['ls'], 'Image' => 'base') 

# Attach to the Container. Currently, the below options are the only valid ones. 
# By default, :stream, :stdout, and :stderr are set. 
container.attach(:stream => true, :stdin => nil, :stdout => true, :stderr => true, :logs => true, :tty => false) 
# => [["bin\nboot\ndev\netc\nhome\nlib\nlib64\nmedia\nmnt\nopt\nproc\nroot\nrun\nsbin\nselinux\nsrv\nsys\ntmp\nusr\nvar", []] 

# If you wish to stream the attach method, a block may be supplied. 
container = Docker::Container.create('Image' => 'base', 'Cmd' => ['find/-name *']) 
container.tap(&:start).attach { |stream, chunk| puts "#{stream}: #{chunk}" } 
stderr: 2013/10/30 17:16:24 Unable to locate find/-name * 
# => [[], ["2013/10/30 17:16:24 Unable to locate find/-name *\n"]] 

# If you want to attach to stdin of the container, supply an IO-like object: 
container = Docker::Container.create('Image' => 'base', 'Cmd' => ['cat'], 'OpenStdin' => true, 'StdinOnce' => true) 
container.tap(&:start).attach(stdin: StringIO.new("foo\nbar\n")) 
# => [["foo\nbar\n"], []] 

这是否帮助？我能问你为什么试图使用docker-api？你不能只用docker volumes (-v)？

Answer 2

当前README错过了关于如何在容器中使用卷的部分。你应该罚款与以下命令与容器的文件夹中运行/foo

container = Docker::Container.create('Cmd' => %w[test -d /foo], 
    'Image' => 'debian:wheezy', 
    'Volumes' => {'/foo' => {}} 
) 

如果需要使用本地文件夹安装，更新Volumes' => {'/foo' => '/local_foo'} 您可以参考测试用例：
