docker-当我运行打包时出现错误

Question

当我运行一些像这样的任务时，我的 gemfile 或 bundle 出现错误：

docker exec -it webapp_web_1 bundle exec rake db:migrate

错误：无法找到 Gemfile 或 .bundle/ 目录

或此命令：

docker-compose logs worker

log:
Attaching to webapp_worker_1
worker_1 | Could not locate Gemfile or .bundle/ directory

Docker文件:

  command: bundle exec sidekiq -e s -c 5 -C config/sidekiq.yml
  environment:

  links:

    - db

此外，我无法从我的配置启动 Sidekiq，我想这是关于卷的问题，但我不确定，我已经以多种方式编辑此文件但没有成功...有什么建议吗？

Docker 版本： 1.9.1

Docker-编译版本 1.6.0rc2

谢谢。

您必须修改 Dockerfile 的最后一部分以匹配 docker 撰写文件的文件夹：

WORKDIR /web
ADD Gemfile /web/
ADD Gemfile.lock /web/
RUN bundle install
