我怎样才能读取httpstream请求的第一个响应: 当我在ruby脚本中对curl http://localhost:7788/containers/sampe/stats发出请求时。它会得到一个每秒接收数据的httpstream。该请求将不会被断开。在使用Ruby获取JSON格式的第一个响应之后，如何断开请求 {"read":"2015-07-17T15:47:20.253706054+08:00","network":{"rx_bytes":1526,"rx_packets":19,"rx_errors":0,"rx_dropped":0,"tx_bytes":738,"tx_packets":9,"tx_errors":0,"tx_dropped":0},"precpu_stats":{"cpu_usage":{"total_usage":0,"percpu_usage":null,"usage_in_kernelmode":0,"usage_in_usermode":0},"system_cpu_usage":0,"throttling_data":{"periods":0,"throttled_periods":0,"throttled_time":0}},"cpu_stats":{"cpu_usage":{"total_usage":1024776164,"percpu_usage":[180823377,321637272,276090785,246224730],"usage_in_kernelmode":240000000,"usage_in_usermode":560000000},"system_cpu_usage":19962290000000,"throttling_data":{"periods":0,"throttled_periods":0,"throttled_time":0}},"memory_stats":{"usage":90214400,"max_usage":90451968,"stats":{"active_anon":34742272,"active_file":9658368,"cache":55472128,"hierarchical_memory_limit":1073741824,"inactive_anon":0,"inactive_file":45813760,"mapped_file":30703616,"pgfault":12415,"pgmajfault":286,"pgpgin":23508,"pgpgout":1483,"rss":34742272,"rss_huge":0,"total_active_anon":34742272,"total_active_file":9658368,"total_cache":55472128,"total_inactive_anon":0,"total_inactive_file":45813760,"total_mapped_file":30703616,"total_pgfault":12415,"total_pgmajfault":286,"total_pgpgin":23508,"total_pgpgout":1483,"total_rss":34742272,"total_rss_huge":0,"total_unevictable":0,"total_writeback":0,"unevictable":0,"writeback":0},"failcnt":0,"limit":1073741824},"blkio_stats":{"io_service_bytes_recursive":[],"io_serviced_recursive":[],"io_queue_recursive":[],"io_service_time_recursive":[],"io_wait_time_recursive":[],"io_merged_recursive":[],"io_time_recursive":[],"sectors_recursive":[]}} {"read":"2015-07-17T15:47:20.253706054+08:00","network":{"rx_bytes":1526,"rx_packets":19,"rx_errors":0,"rx_dropped":0,"tx_bytes":738,"tx_packets":9,"tx_errors":0,"tx_dropped":0},"precpu_stats":{"cpu_usage":{"total_usage":0,"percpu_usage":null,"usage_in_kernelmode":0,"usage_in_usermode":0},"system_cpu_usage":0,"throttling_data":{"periods":0,"throttled_periods":0,"throttled_time":0}},"cpu_stats":{"cpu_usage":{"total_usage":1024776164,"percpu_usage":[180823377,321637272,276090785,246224730],"usage_in_kernelmode":240000000,"usage_in_usermode":560000000},"system_cpu_usage":19962290000000,"throttling_data":{"periods":0,"throttled_periods":0,"throttled_time":0}},"memory_stats":{"usage":90214400,"max_usage":90451968,"stats":{"active_anon":34742272,"active_file":9658368,"cache":55472128,"hierarchical_memory_limit":1073741824,"inactive_anon":0,"inactive_file":45813760,"mapped_file":30703616,"pgfault":12415,"pgmajfault":286,"pgpgin":23508,"pgpgout":1483,"rss":34742272,"rss_huge":0,"total_active_anon":34742272,"total_active_file":9658368,"total_cache":55472128,"total_inactive_anon":0,"total_inactive_file":45813760,"total_mapped_file":30703616,"total_pgfault":12415,"total_pgmajfault":286,"total_pgpgin":23508,"total_pgpgout":1483,"total_rss":34742272,"total_rss_huge":0,"total_unevictable":0,"total_writeback":0,"unevictable":0,"writeback":0},"failcnt":0,"limit":1073741824},"blkio_stats":{"io_service_bytes_recursive":[],"io_serviced_recursive":[],"io_queue_recursive":[],"io_service_time_recursive":[],"io_wait_time_recursive":[],"io_merged_recursive":[],"io_time_recursive":[],"sectors_recursive":[]}}

在Travis-ci上的Docker容器: 我有一个Dockerfile，我试图使用RSpec，serverspec和docker-api进行testing。在本地（使用boot2docker，因为我在OS X上）这个工程很好，所有我的testing通过，但在travis-ci没有testing通过。我的.travis.yml文件是这样的： language: ruby rvm: – "2.2.0" sudo: required cache: bundler services: – docker before_install: – docker build -t tomasbasham/nginx . – docker run -d -p 80:80 -p 443:443 –name nginx -v $(pwd)/nginx.conf:/etc/nginx/nginx.conf tomasbasham/nginx script: bundle exec rspec 我在这里做了一些明显的错误吗？我已经创build并在travis-ci上运行的存储库位于GitHub上。可能还有一些我不知道的错误

Dockerize Ruby脚本，将目录作为input/输出: 我是docker的新手，我需要帮助dockerize一个ruby脚本，它需要一个input目录和输出目录。即generate_rr_pair.rb BuildRR -n /data/ -o /output 脚本是做什么的，它会采取-n选项（input），并检查目录是否存在，如果它使用里面的文件作为input。脚本将输出数据到-o选项（输出）。如果输出目录不存在，脚本将在那里创build目录和输出文件。我如何创build一个Dockerfile来处理这个？我应该把它们作为环境variables吗？或者我应该使用安装的卷？但是由于脚本处理fileIO，我不确定是否需要卷。 input目录应该已经存在于主机上，并且输出目录将被创build。这两个目录，应该停留在docker集装箱停止后。

在Linux上运行时gsub编码错误Docker容器US-ASCII中的无效字节序列: 我有一个string，我从"\r\n"为"\n"行结束使用： input.gsub(/\r\n?/, "\n") 当我在Windows主机上运行它时，它工作正常。当我运行在我的Linux主机上，在一个泊坞窗容器中，我得到这个错误： in `gsub': invalid byte sequence in US-ASCII (ArgumentError) 我正在运行Ruby 2.2。

dockerapache乘客：错误不能加载这样的文件捆绑器/设置（LoadError）: 我试图build立一个运行Apache（+乘客），铁路和shibbolethdocker形象。不幸的是，我不能得到apache +乘客运行…我欣赏每一个提示！也许这是一个权限问题？一切都以root身份进行安装，但显然有些进程是以nobody身份运行的（如错误日志所示）。我的docker基础图像是“ruby：2.0.0”（debian 8）。在这个图像中，我通过apt-get和乘客通过“gem install passenger -v 4.0.59”安装了apache2，apache2-threaded-dev，libapr1-dev，libaprutil1-dev。在此之后，我使用passenger-install-apache2-module来安装模块。这里是错误日志： cannot load such file — bundler/setup (LoadError) /usr/local/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require' /usr/local/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require' /usr/lib/ruby/vendor_ruby/phusion_passenger/loader_shared_helpers.rb:411:in `activate_gem' /usr/lib/ruby/vendor_ruby/phusion_passenger/loader_shared_helpers.rb:295:in `block in run_load_path_setup_code' /usr/lib/ruby/vendor_ruby/phusion_passenger/loader_shared_helpers.rb:416:in `running_bundler' /usr/lib/ruby/vendor_ruby/phusion_passenger/loader_shared_helpers.rb:294:in `run_load_path_setup_code' /usr/share/passenger/helper-scripts/rack-preloader.rb:99:in `preload_app' /usr/share/passenger/helper-scripts/rack-preloader.rb:153:in `<module:App>' /usr/share/passenger/helper-scripts/rack-preloader.rb:29:in `<module:PhusionPassenger>' /usr/share/passenger/helper-scripts/rack-preloader.rb:28:in `<main>' Environment (value of RAILS_ENV, RACK_ENV, WSGI_ENV, NODE_ENV and PASSENGER_APP_ENV) development Ruby interpreter […]

在Docker容器中访问Sinatra应用程序的问题: 我有一个sinatra API服务器，我可以成功运行本地端口9292我想在一个容器中运行。我用以下创build一个Dockerfile： FROM ruby:2.2.0 RUN apt-get update -qq && \ apt-get install -y build-essential libpq-dev nodejs –no-install-recommends && \ rm -rf /var/lib/apt/lists/* && \ mkdir /myapp WORKDIR /myapp ADD . /myapp RUN bundle install EXPOSE 9292 CMD bundle exec rackup config.ru 在构build映像后，我运行以下命令启动容器： docker run -it -p 9292:9292 –rm api-server 我确认该应用程序已启动并正在运行，并提供了其他详细信息： Listening on localhost:9292, CTRL+C […]

如何更改Rails基础Docker镜像的Ruby和Rails版本？: Docker基本的图像轨道为Ruby on Rails提供了一个完整的环境。它从ruby上游图像中拉出。 rails基础图像指定了Ruby和Ruby on Rails版本。如果我们想要使用不同的Ruby和Ruby on Rails版本呢？我们在我们的项目文件夹中编辑我们的Dockerfile吗？或者，我们进入机器，安装我们想要的ruby版本，然后build立自己的图像？更多细节： rails的基础图像文档说，你的doc文件可以简单地是一行代码： FROM rails:onbuild 这行代码从Docker Hub上的rails图像中提取。这个图像有它自己的Dockerfile。这个Dockerfile的第一行是FROM ruby:2.2 。为了重申这个问题，使用不同的Ruby和Ruby on Rails版本创build基于rails图像的容器的最佳方式是什么？如果可能的话，一些示例代码可能有助于理解如何做到这一点。

使用宙斯与Rails 3和docker工人: 我们有一个Rails 3.2.9应用程序，最近在开发中切换到了Docker。到目前为止，我一直在我的机器上使用zeus来预装代码库，并且更快地执行Rspec的testing。但是，你将如何与docker实现这一点？当我尝试安装宙斯与我的容器与gem install zeus并开始与zeus start我得到 Unable to accept socket connection. It looks like Zeus is already running. If not, remove .zeus.sock and try again. 在我的文件系统中有一个.zeus.soc （注意最后缺less的k ）。有没有人得到这个与Docker的工作？
