Phusion Passenger Docker图像上的错误“在任何源中找不到rake-10.5.0”

docker-compose passenger docker ruby-on-rails

我正在尝试使用Docker和 Phusion Passenger Ruby base image ,但每当我尝试从浏览器访问应用程序时,我都会收到以下错误:

这是我的 Dockerfile :

FROM phusion/passenger-ruby22:0.9.18

# Set correct environment variables.
ENV HOME /root

# Use baseimage-docker's init process.
CMD ["/sbin/my_init"]

# Enable Nginx/Passenger
RUN rm -f /etc/service/nginx/down

# Enable portals virtual host
RUN rm /etc/nginx/sites-enabled/default
COPY portals.conf /etc/nginx/sites-enabled/portals.conf
RUN mkdir /home/app/webapp

# Load env vars into nginx
COPY rails-env.conf /etc/nginx/main.d/rails-env.conf

# Install gems dependencies
COPY Gemfile* /tmp/
WORKDIR /tmp
RUN bundle install

# Copy rails app
WORKDIR /home/app/webapp
COPY . ./
RUN chown -R app:app ./

# Clean up APT when done.
RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

我试着运行bundler作为 RUN bundle install --deployment 但效果并不好。我正在通过 RAILS_ENV 和 PASSENGER_APP_ENV 通过 rails-env.conf 文件,它们都被设置为生产(根据乘客图像文档,这是默认值)。

如果我 docker exec -it bash <ID> 进入容器并运行 gem list 我看到所有的宝石都安装好了,所以我不知道怎么了。

此错误是由于软件过期造成的。因为乘客图像不经常更新,所以在您的 Dockerfile 。这是我通常设置 Dockerfile文件 基于phusion图像:

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", "--"]

SYSTEM_UPDATE 只是一个缓存破坏者变量。当我启动时,所有的包都将在下一个docker构建中更新。它应该经常颠簸。

我还保证 gem 和 bundler 在运行前完全更新 bundle install .

此外,复制您的 Gemfile 和 Gemfile.lock 到tmp目录,只需将其复制到应用程序目录。

你可以删除你的决赛 Clean up APT when done. 命令-那真的不是合适的地方。应该有一个 RUN 运行所有 apt-get 命令。

看看 https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/ 有关设置Dockerfile的最佳实践,特别是关于使用apt-get的部分。

对我来说,瑞克就在那里,我用

rake rails:update

玩得高兴
