Bundler :: Gemnotfound:在任何来源中都找不到Rake-122.3.2

Question

运行带有卷的Rails Docker容器时错误Bundler：无法加载命令：Rails(/usr/local/bundle/bin/rails(Bundler :: Gemnotfound：在任何来源中都找不到Rake-122.3.2

我能够在没有音量的情况下运行Rails Docker容器。但是，当我这样附加音量时：

docker run --name rails-chat-tutorial-web 
            -e DATABASE_HOST=172.17.0.1 
            -e DATABASE_PORT=5432 
            -e DATABASE_USERNAME=postgres 
            -e DATABASE_PASSWORD=postgres 
            -e REDIS_URL=redis://172.17.0.1:6379/1 
            -p 3000:3000 
            -v $(pwd):/application rails-chat-tutorial

我将获得此错误输出：

bundler: failed to load command: rails (/usr/local/bundle/bin/rails)

我尝试在我的dockerfile中加入这些行，但仍会出现错误：

RUN gem install rake -v '12.3.2'
RUN bundle install --binstubs
RUN bundle install --path vendor/bundle
RUN bundle install --local
RUN bun

dle安装 - 本地-PATH =供应商/缓存

这是我的dockerfile：

FROM ruby:2.5.0-stretch
COPY ./Gemfile ./application/
COPY ./Gemfile.lock ./application/
WORKDIR /application
ENV BUNDLER_VERSION 2.0.1
RUN gem install bundler -v '2.0.1'

RUN npm install yarn -g
COPY . .
ENV RAILS_ENV production 
ENV SECRET_KEY_BASE production_test_key rails c
RUN bundle exec rake assets:precompile
EXPOSE 3000
CMD bundle exec rails server

gemfile的内容：

如果我用外壳和宝石列表运行轨道容器，我会得到'Rake(12.3.2，12.3.0('

我一直在过去2天进行，但没有进展。

预先感谢您提供一些指导的人。

Answer 1

添加 docker run -v $(pwd):/application选项时，它将图像中的/application目录中的所有内容隐藏并用主机系统中的内容代替。特别是包括/application/vendor目录：dockerfile中的任何 bundle命令都被完全忽略了，而主机系统的./vendor目录则使用。

如果您必须在部署的容器中进行实时编辑和重新加载，那么这并不是一个很好的答案。节点生态系统是相似的(第三方库在./node_modules中(，大多数类似的问题是关于节点而不是Ruby的。在Docker中添加一个音量，但排除子文件夹建议为./vendor添加匿名卷；仅第一次运行应用程序的，它将从图像中填充，但是如果您以后更改Gemfile，则不会更新并复制此设置在Kubernetes等集群环境中不必要地复杂。

如果您想尝试匿名 - 体积路径，则可能看起来像

docker run --name rails-chat-tutorial-web ... 
  -v $PWD:/application -v /application/vendor 
  rails-chat-tutorial
$EDITOR Gemfile
bundle install
docker stop rails-chat-tutorial-web
docker rm -v rails-chat-tutorial-web
docker run ...

(docker rm -v将删除匿名卷，并将在下一个docker run上重新创建带有更新的内容。

对我来说效果很好的序列是为了完全无知的Docker开发我的应用程序：在本地开发它，运行它，编写良好的RSPEC测试，并且一般认为它有效。只有这样，我才能 docker build和 docker run一个图像，而无需将我的源代码绑定到其中。如果它破裂了，那么我在本地开发环境上重现问题，为其编写测试并修复它，然后重复docker build; docker run序列。
