AWS Elastic Beanstalk上的Rails 5出现puma错误（getcwd）

Question

我当时以为每项工作都可以在AWS Elastic Beanstalk上部署Rails 5 API，但Puma尚未开始工作。 Puma启动片刻，然后自行关闭

EB的错误日志

我检查了VPC，安全组，数据库和Redis，所有这些工作正常

我已经在旧服务器上部署了，但是可以尝试创建新服务器并使用相同的配置

更新puma.rb

threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }
threads threads_count, threads_count

port ENV.fetch("PORT") { 3003 }

environment ENV.fetch("RAILS_ENV") { "development" }

plugin :tmp_restart

更新puma.config

files:
   "/opt/elasticbeanstalk/support/conf/pumaconf.rb":
    mode: "000644"
  content: |
  directory '/var/app/current'
  workers Integer(ENV['WEB_CONCURRENCY'] || 2)
  threads_count = Integer(ENV['MAX_THREADS'] || 16)
  threads threads_count, threads_count
  bind 'unix:///var/run/puma/my_app.sock'
  stdout_redirect '/var/log/puma/puma.log', '/var/log/puma/puma.log', true
  daemonize false
