Ruby on rails “错误”；在任何来源中都找不到rake-10.5.0“；论飞信客运码头形象

我正在尝试使用Docker和部署Rails应用程序，但每当我尝试从浏览器访问该应用程序时，都会出现以下错误：

web_1 | [ 2016-02-08 04:18:44.6861 31/7ff292141700     age/Cor/App/Implementation.cpp:304 ]: Could not spawn process for application   /home/app/webapp: An error occurred while starting up the preloader.

Dockerfile

：

FROM phusion/passenger-ruby22:0.9.18

ENV SYSTEM_UPDATE=1
RUN apt-get update \
&& apt-get upgrade -y -o Dpkg::Options::="--force-confold" \
&& apt-get clean \
&& rm -rf /var/lib/apt/lists/*

WORKDIR /home/app
COPY Gemfile /home/app/Gemfile
COPY Gemfile.lock /home/app/Gemfile.lock
RUN gem update --system && \
gem update bundler && \
bundle install --jobs 4 --retry 5

# The rest of your app setup here

ENTRYPOINT ["/sbin/my_init", "--"]

我尝试以

运行bundle安装--deployment

的方式运行bundler，但效果不佳。我通过

RAILS ENV.conf

文件传递

RAILS_ENV

和

PASSENGER_APP_ENV

，它们都设置为生产（根据乘客图像文档，这是默认设置）

---

如果我

docker exec-it bash

进入容器并运行

gem list

我看到所有gem都已安装，所以我不知道是什么问题。

此错误是由于软件过时造成的。由于乘客图像不经常更新，因此务必更新

Dockerfile

中的所有内容。这是我通常基于phusion图像设置

Dockerfile

的方式：

SYSTEM\u UPDATE

只是一个缓存buster变量。当我升级时，所有包都将在下一个docker版本中更新。它应该经常被碰撞

我还确保

gem

和

bundler

在运行

bundle install

之前完全处于最新状态

此外，将

Gemfile

和

Gemfile.lock

复制到tmp目录没有任何好处，只需将其复制到应用程序目录即可

完成后，您可以删除最终的

清理APT。

命令-这确实不是正确的位置。应该有一行

RUN

在一个层中运行所有

apt get

命令

---

查看关于设置Dockerfile的最佳实践，特别是关于使用apt get的部分。

对于我来说，rake就在那里，我使用

rake rails:update

---

玩得开心

奇怪的是，

CMD

不接近Dockerfile的结尾_(ツ)_/''这就是为什么文档有它不确定它是否会有帮助，但一定要更新gem和bundler:

运行gem update--system&&gem update bundler

。确实，您应该使用

运行apt get update&&apt get upgrade-y

更新所有包。它实际上在@ScottJacobsen运行，谢谢！将此作为答案发送，我将接受：）我得到了同样的错误，但我不知道什么是Dockerfile。我刚刚使用

gem install passenger

安装了phusion passenger，然后使用

passenger安装nginx模块

。如何更新乘客信息？
