私人宝石未在Docker中安装

Question

我正在尝试使用docker运行Rails应用程序。github的ssh url安装的gem如下：

宝石文件

gem 'swagger-docs', :git => 'git@github.com:xyz/swagger-docs.git', :branch => 'my_branch'

我添加了keysdocker中的in，它能够克隆所需的repo并从git安装gem。

Docker文件

RUN mkdir -p /root/.ssh
COPY ./id_rsa /root/.ssh/id_rsa

RUN chmod 700 /root/.ssh/id_rsa

RUN ssh-keygen -f /root/.ssh/id_rsa -y > /root/.ssh/id_rsa.pub

RUN ssh-keyscan github.com >> /root/.ssh/known_hosts

当我构建它（包括bundle install）时，一切顺利，并且图像成功构建。但是当我运行时docker-compose up，它给出以下错误

/usr/local/bundle/gems/bundler-1.9.2/lib/bundler/source/git/git_proxy.rb:155:in `allowed_in_path': The git source git@github.com:xyz/swagger-docs.git is not yet checked out. Please run `bundle install` before trying to start your application (Bundler::GitError)

Answer 1

尝试在 Gemfile 中将 git 替换为 https，即

  gem 'swagger-docs', git: 'https://github.com:xyz/swagger-docs.git', branch: 'my_branch'

...或者在运行捆绑安装之前将其添加到您的 Dockerfile 中：

  RUN git config --global url."https://".insteadOf git://

如果没有任何效果，那么只需运行bundle install两次，即

  ...
  RUN gem install bundler && bundle install

  CMD bundle install && rails s -p 3000 -b 0.0.0.0
