軌，Webpacker和碼頭工人：不能分配請求的地址 - 連接（2）[:: 1]：3035

我試圖讓webpacker與docker，puma 3.10.0，rails 5.1.4和webpacker 3.0.1工作。軌，Webpacker和碼頭工人：不能分配請求的地址 - 連接（2）[:: 1]：3035

我有以下的配置設置爲泊塢窗：

Dockerfile

FROM ruby:2.4.1 

ENV DIR=/app \ 
    BUNDLE_JOBS=4 

RUN curl -sL https://deb.nodesource.com/setup_7.x | bash - 
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - 
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list 

RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs openssl yarn 

RUN mkdir $DIR 
WORKDIR $DIR 

ADD Gemfile $DIR/Gemfile 
ADD Gemfile.lock $DIR/Gemfile.lock 

RUN bundle install 
RUN gem install foreman 

ADD . $DIR 

EXPOSE 3000 

ADD docker-entrypoint.sh /entrypoint.sh 
ENTRYPOINT ["/entrypoint.sh"] 

CMD bundle exec rails s -p 3000 -b 0.0.0.0

泊塢窗，compose.yml

version: "2" 

services: 
    db: 
    image: postgres 
    env_file: 
     - docker.env 
    webpacker: 
    build: . 
    command: bundle exec bin/webpack-dev-server 
    ports: 
     - "8080:8080" 
    app: 
    build: . 
    links: 
     - db:db 
    ports: 
     - "3000:3000" 
    depends_on: 
     - db 
     - webpacker 
    env_file: 
     - docker.env 
    command: bundle exec rails s -p 3000 -b '0.0.0.0'

不幸的是，每當我跑docker-compose up和訪問localhost:3000，我得到以下錯誤：

#<Errno::EADDRNOTAVAIL: Cannot assign requested address - connect(2) for [::1]:3035>

任何幫助是極大的讚賞。謝謝你們。

你所有的容器都已啓動並正在運行？什麼容器返回錯誤提到？ – papey

貼出'docker-compose logs' –

您需要設置--listen-host的值傳遞給webpack-dev-server。

您可以通過編輯文件config/webpacker.yml和改變從localhost的development:dev_server:host:值0.0.0.0實現這一目標，應該解決的問題。
