Foreman/Puma没有在dev env中使用指定的端口

Question

我在我的application.yml中设置端口为3000(figaro管理env变量) rails s使用端口3000但是当我运行时foreman start(按照Heroku的推荐)我得到以下输出

14:53:23 web.1  | started with pid 24425
14:53:23 web.1  | [24425] Puma starting in cluster mode...

Procfile

web: bundle exec puma -C config/puma.rb

配置/ puma.rb

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
port        ENV['PORT']     || 3000
environment ENV['RACK_ENV'] || 'development'

on_worker_boot do
  ActiveRecord::Base.establish_connection
end

配置/ application.yml

PORT: "3000"

美洲狮港的神秘面纱解决了.

将此打印件放在config/puma.rb中

然后你会看到端口被神秘地设置为5000,即使它不在你的ENV中.

在底部修复.

puma_port = ENV['PORT'] || 3000
puts "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ"
puts "puma_port is #{puma_port}"
puts "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ”

打印出来

16:49:28 web.1  | ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
16:49:28 web.1  | puma_port is 5000
ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ

然后将此行放在Procfile中(而不是用于Heroku的行).我有一个叫Procfile.dev

web: PORT=3000 bundle exec puma -C config/puma.rb

我用这个命令运行它:

foreman start -f Procfile.dev
