Question

我正在尝试将一个小型Rails应用程序部署到Bluemix。它在当地工作正常。我得到的错误是：

Instance (index 0) failed to start accepting connections
2015-12-13T20:57:11.571-0800[API/2]OUTApp instance exited with guid
 68527a7d-ee7c-40a9-a500-0b44c01d267c payload: 
{"cc_partition"=>"default", 
"droplet"=>"68527a7d-ee7c-40a9-a500-0b44c01d267c", 
"version"=>"3b480d7d-3483-435b-bbfc-b4682a9994e2", 
"instance"=>"faed828f09364ac79a32503deaace288", "index"=>0, 
"reason"=>"CRASHED", "exit_status"=>-1, 
"exit_description"=>"failed to accept connections within health check timeout", 
"crash_timestamp"=>1450069031}

到目前为止我发现的所有答案都说这是一个端口问题，而且当我使用

进行部署时也是如此

cf push <myapp> --no-route

它很好，即没有错误消息。

我使用puma作为服务器和我的Procfile（带有拼写，它是根）已经

web: bundle exec puma -p $PORT

即便如此，Bluemix也开始使用puma，但总是使用端口3000.即使我放了类似的东西

web: bundle exec puma -p 1234

它从端口3000开始。所以它似乎忽略了Procfile。我做错了什么？

根据Jeff的问题，我的buildpack是ruby 1.6.7，这是我的Gemfile：

source 'https://rubygems.org'

ruby "2.2.2"

gem 'rails', '4.2.1'

gem 'pg'
gem 'activerecord-postgresql-adapter'

gem 'cf-autoconfig', '~> 0.2.1'
gem 'rails_12factor'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'

# Use jquery as the JavaScript library

gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
gem 'byebug'

end

gem 'devise'

gem 'puma'

这是日志

感谢您的帮助！

首先看一下你在端口3000上的开始。 Bluemix / Cloud Foundry为您分配一个可运行的端口。您需要manifest.yml中的以下内容。您需要更换应用程序的信息。 $PORT告诉Ruby绑定到Bluemix的指定端口。

---
applications:
#swap out myapp-jbs for your own app name
- name: myapp-jbs
  memory: 1GB
  instances: 1
  path: .
  command: bundle exec rake db:setup && bundle exec rails s -p $PORT
  services:
  #swap out the below for your own
  #cf cs elephantsql turtle yourownname
    - postgres-myapp

另外使用以下命令推送您的应用程序。

cf push -b https://github.com/cloudfoundry/ruby-buildpack.git
