Docker -компонентный сервер Faye pub-sub не будет публиковать sh по сети

0 голосов
/ 27 марта 2020

У меня есть приложение Rails 3, которое зависит от private_pub . В моей попытке Dockerize это приложение, кажется, все работает, как ожидалось, кроме моего контейнера Faye. Я знаю, что мое приложение может подключиться к контейнеру, но, похоже, Faye не может опубликовать sh.

Ошибка: 

undefined method `empty?' for nil:NilClass

Я немного нуб, когда дело доходит до Docker. Я полагаю, что все правильно подключил, и я попытался следовать этому решению , но в итоге получил тот же результат.

Я создал Docker Hub image для Фэй.

Вот мой Dockerfile: 

FROM ruby:2.3.8

RUN apt-get update -qq && apt-get install -y

# Setup path
ENV APP_PATH .

# Create dir
RUN mkdir /faye
WORKDIR /faye

RUN gem install faye private_pub thin
COPY ${APP_PATH}/private_pub.ru /faye/private_pub.ru
COPY ${APP_PATH}/private_pub.yml /faye/private_pub.yml

CMD ["rackup", "private_pub.ru", "-s", "thin", "-E", "production", "-o", "0.0.0.0"]

Вот мой docker -compose.yml: 

version: '3'
services:
  db:
    image: mariadb
    environment:
      MYSQL_ALLOW_EMPTY_PASSWORD: 1
      MYSQL_DATABASE: round_three_development
    volumes:
      - db_data:/var/lib/mysql
      - ./docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
  faye:
    image: jforgue/faye
    ports:
      - "9292:9292"
  web:
    build:
      context: .
      dockerfile: docker/Dockerfile
    command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
    volumes:
      - .:/round-three-docker
    ports:
      - "3000:3000"
    depends_on:
      - db
      - faye
volumes:
  db_data: { driver: local }

Я почти уверен, что это ошибка сети, но я не могу найти, где я ошибся.
