有没有办法编译和静态链接Docker的ruby库？
UPDATED 6 29 2015：
InfraRuby编译器和运行时静态类型的Ruby在JVM上！
我想要一个单独的二进制文件，静态链接，从一个简单的红宝石爬行器建立一个苗条的码头码头容器。
I'd like to have a single binary, statically linked, out of a simple ruby crawler to build a slim docker container.
/ p>
Something like what Go produces with:
CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .
有没有办法用ruby / rails做这个？
Is there a way of doing this with ruby/rails?
为什么要打扰？当您为您的红宝石应用程序创建Docker容器时，您已经创建了一个方便的发行包。
Why bother? When you create a docker container for your ruby app you are already creating a convenient package for distribution.
我建议您查看 ruby 和 rails 官方图片。在容器构建过程中，他们将运行gem bundler来打包依赖关系。
I would suggest checking out the ruby and rails official images. During the container build process they will run the gem bundler in order to package dependencies.
简单的红宝石脚本项目
├── Dockerfile
├── Gemfile
├── Gemfile.lock
└── helloworld.rb
图像是正常建立的
docker build -t my-ruby-app .
并运行如下：
$ docker run --rm my-ruby-app
