развернуть производственное приложение Rails с ActionCable на puma и nginx от docker

Question

Я новичок в использовании ActionCable.

Я пытался собрать приложение rails с помощью docker с помощью actioncable, и websocket не работал.

журнал от redis:

config / cable.yml:

development:

config / environment / production.rb:

config.eager_load = true
config.action_cable.mount_path = '/cable'
config.action_cable.url = "ws://localhost/cable"

nginx.default.conf:

server {
  listen       80;
  server_name  localhost;

  location / {
    proxy_pass http://unix:/app/tmp/sockets/puma.sock;
    proxy_set_header X-Forwarded-Host localhost;
  }

  location /cable {
   proxy_pass http://unix:/app/tmp/sockets/puma.sock;
   proxy_http_version 1.1;
   proxy_set_header Upgrade $http_upgrade;
   proxy_set_header Connection "upgrade";
  }
}

puma.rb

bind "unix:///app/tmp/sockets/puma.sock"

при использовании docker-compose up --build все в порядке, но когда я перезагружаю страницу, журнал, приведенный выше, позволит контейнеру app_1 сломаться, как

myapp_app_1 exited with code 1

Как я могу это исправить?
