【问题描述】：

我在 docker 中调试我的应用程序时遇到问题。我认为我的设置是正确的，因为没有调试器一切正常。

端口

command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
    volumes:
      - .:/usr/src/app
    ports:
      - "3000:3000"
      - "1234:1234"
      - "26162:26162"
      - "26168:26168"

错误：（网站没有响应）

这是什么版本的 RubyMine？

【解决方案1】：

我刚刚想通了。

我的解决方案将 WEB_CONCURRENCY 设置为 0 (config/puma.rb)

workers ENV.fetch("WEB_CONCURRENCY") { 0 }

对于生产系统，我更改了.env 文件中的值。

WEB_CONCURRENCY=2

# Note that workers are not supported for JRuby or Windows
#workers ENV.fetch("WEB_CONCURRENCY") { 2 }
