Question

我在docker-compose up命令

时收到错误消息

我的Dockerfile：

FROM ruby:2.3

RUN apt-get update -yqq \
  && apt-get install -yqq --no-install-recommends \
    postgresql-client \
    nodejs \
  && apt-get -q clean 


# Pre-install gems with native extensions
RUN bundle update nokogiri
RUN gem install nokogiri -v "1.6.8.1"

WORKDIR /usr/src/app
COPY Gemfile* .
RUN bundle install
COPY . .

CMD script/start

我的docker-compose.yml：

version: "2"

volumes:
  db-data:
    external: false

services:
  db:
    image: postgres
    env_file: .env
    volumes:
      - db-data:/var/lib/postgresql/db-data

  app:
    build: .
    env_file: .env
    volumes:
      - .:/usr/src/app
    ports:
      - "3000:3000"
    depends_on:
      - db

我的gemfile：

  #gem 'capistrano-rbenv', github: "capistrano/rbenv"
end

我想提一下，我在我的rails app文件夹中运行chmod -R 777 .。我得到的错误是：

Could not locate Gemfile
ERROR: Service 'app' failed to build: The command '/bin/sh -c bundle update nokogiri' returned a non-zero code: 10

Answer 1

你的Dockerfile中有：

RUN bundle update nokogiri
RUN gem install nokogiri -v "1.6.8.1"

因为没有安装，所以无法更新nokogiri gem。你还要在下一行安装它。您可能希望删除RUN bundle update nokogiri或重新考虑如何更好地使用它。

无法通过docker compose找到Gemfile错误
