Ruby on rails Rails Docker容器中的捆绑安装失败

部署docker容器时遇到问题，主要原因是

bundler

无法执行其

install

命令。使用

passenger

在本地运行

bundle install

似乎工作正常，只有部署过程在设置gems时会导致问题

我对

Docker

比较陌生，我不会称自己为

Rails

专家。这就是说，我很难理解

bundler

是如何以这种方式（尤其是与

Docker

一起）把整个事情搞砸的

我用的是乘客码头基地的图片，如果有任何关联的话

这是我的

Gemfile

：

gem 'doorkeeper'
gem 'doorkeeper-jwt'
gem 'aws-sdk-rails'
gem 'rack-cors', :require => 'rack/cors'
gem 'active_model_serializers', github: 'rails-api/active_model_serializers'
gem 'passenger'
gem 'rails', '4.2.6'
gem 'rails-api'
gem 'pg'
gem 'devise'
gem 'schema_plus'
gem 'pusher'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do

  gem 'byebug'
  gem 'web-console', '~> 2.0'
  gem 'spring'
  gem 'rspec-rails'
  gem 'factory_girl_rails', '~> 4.0'
  gem 'database_cleaner'

end

RUN mkdir /home/app/myapp
WORKDIR /home/app/myapp

COPY Gemfile /home/app/myapp/
COPY Gemfile.lock /home/app/myapp/
RUN chown -R app:app /home/app/myapp
RUN sudo -u app bundle install --deployment --verbose --path vendor/cache

ADD . /home/app/myapp
RUN chown -R app:app /home/app/myapp

这是

Dockerfile的（部分）

：

gem 'doorkeeper'
gem 'doorkeeper-jwt'
gem 'aws-sdk-rails'
gem 'rack-cors', :require => 'rack/cors'
gem 'active_model_serializers', github: 'rails-api/active_model_serializers'

gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do

  gem 'byebug'
  gem 'web-console', '~> 2.0'
  gem 'spring'
  gem 'rspec-rails'
  gem 'factory_girl_rails', '~> 4.0'
  gem 'database_cleaner'

end

RUN mkdir /home/app/myapp
WORKDIR /home/app/myapp

COPY Gemfile /home/app/myapp/
COPY Gemfile.lock /home/app/myapp/
RUN chown -R app:app /home/app/myapp
RUN sudo -u app bundle install --deployment --verbose --path vendor/cache

ADD . /home/app/myapp
RUN chown -R app:app /home/app/myapp

当我尝试部署时，会出现以下错误：

来自应用程序的消息：看起来Bundler无法找到 宝石也许您没有安装此应用程序所需的所有gems 需要。要安装gems，请运行：

捆绑安装

如果这不起作用，那么问题可能是由您的 应用程序在不同于预期的环境下运行 到请检查以下内容：

此应用程序是否应作为

用户？

此应用程序是否在正确的Ruby上运行 口译译员下面你会 查看乘客试图使用的Ruby解释器。

这里的变量太多了。您的问题中不清楚“部署”是什么意思？“当我尝试部署时”--这是类似于

docker run…

还是

docker compose…

？或者是Heroku/AWS/DigitalOcean/CF类型的推送？您是本地运行Docker、boot2Docker还是远程运行Docker

通常，是否可能在容器内没有出站连接？你有代理人吗？如果是这样的话，同样的代理设置可能需要在容器中进行——如何进行取决于代理设置和Docker的具体情况

如果您能够将任何网络工具的安装添加到docker文件中，请尝试类似于

docker exec curl rubygems.org

（或者如果您没有运行的容器，

docker run curl rubygems.org

希望这能帮助你朝着正确的方向开始
