Question

最近使用Dockerfile使用docker-compose up会给我以下错误，我无法弄清楚为什么会发生这种情况。我搜索了几个小时无济于事。有人知道为什么会这样吗？

Dockerfile中有几个问题：

您应该将apt-get install部分合并为：

RUN \
    apt-get -y update \
    && apt-get install -y --force-yes nginx lynx nano curl build-essential autoconf automaker libass-dev libfreetype6-dev \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

RUN /srv/myapp不起作用，因为它是一个目录。
有拼写错误吗？您可以尝试RUN gem install bundle。

RUN gem install bundler

最后，凭借Dockerfile，我无法重现那个＆＃34;没有这样的文件或目录＆＃34;错误。因此我需要你的rake文件：

Step 13 : RUN bundle exec rake assets:precompile --trace

docker-rails是我刚创建的一个项目，用于使用docker（和CI）轻松实现。我认为它可以帮助您减少在docker上启动和运行rails所需的配置量。

查看development配置中的提示，同时结帐wiki了解先决条件/设置。如果你在OSX上，小艇非常有帮助，而ubuntu在很大程度上只是一个普通的设置（尽管你可能需要在该页面上调整UFW）。
