在Docker上捆绑安装失败

我在我的Rails应用程序中使用Docker。 现在我尝试在新机器上构build它，并且遇到一些问题。

当我运行docker-compose -f dcom-dev.yml run --user $(id -u) web bundle install它开始工作，但失败

 An error occurred while installing debug_inspector (0.0.2), and Bundler cannot continue. Make sure that `gem install debug_inspector -v '0.0.2'` succeeds before bundling. 

如果我尝试docker-compose -f dcom-dev.yml run --user $(id -u) web gem install debug_inspector -v '0.0.2'它成功执行，告诉gem的intalled。

在安装捆绑产生可怕的输出，如：

 Errno::EACCES: Permission denied @ rb_sysopen - /bundler_cache/extensions/x86_64-linux/2.3.0-static/pg-0.18.4/gem_make.out 

要么

 sudo: unknown uid 1000: who are you? 

whoami运行没有任何问题，所以我不知道，为什么它问我这么奇怪的问题:)

dcom-dev.yml ：

 version: '2' services: db: image: postgres volumes_from: - db_data nginx: build: context: ./service/nginx ports: - "1935:1935" - "80:80" depends_on: - web volumes_from: - records processor: build: context: ./service/processor ports: - "3322:22" volumes_from: - records web: &app_base build: . command: bundle exec rails s -p 3000 -b '0.0.0.0' volumes_from: - bundler_cache volumes: - .:/app ports: - "3000:3000" depends_on: - db - processor env_file: .env worker: <<: *app_base ports: [] command: bundle exec rake jobs:work db_data: image: busybox volumes: - /var/lib/postgresql/data records: image: busybox volumes: - /records bundler_cache: image: busybox volumes: - /bundler_cache 

Dockerfile是关于ruby的一部分：

这是bundle instal --verbose的输出bundle instal --verbose

我可以看到它试图使用ruby2.3.0而我的Gemfile指定2.3.1。 通常情况下，它会说这些，但现在保持沉默。

这是什么问题？ 我该怎么办？ 谢谢！

========== Upd 2 ==================我已经意识到，如果我运行命令没有--user $(id -u) ，所以我运行docker-compose -f dcom-dev.yml run web bundle install ，它给了我这样的输出：

Make sure that `gem install debug_inspector -v '0.0.2'` succeeds before bundling. 

很显然， gem install debug_inspector -v '0.0.2'成功。 另外我不知道，如果我应该使用 – 用户或不。 如果没有，我运行捆绑器作为sudo，这是不好的，如果我使用，用户没有权限写入到捆绑器文件夹。

得到它了！ 由于我在DigitalOcean上使用液滴，我设法发现错误Cannot allocate memory意味着我需要创build一个交换。 这真的有帮助。

Answer 2

您的用户ID在您的新机器上是不同的，看起来您已经将此用户ID硬编码到您的映像中，至less是以文件权限的forms。 标志--user $(id -u)告诉docker-compose以你的主机上的用户身份运行你的容器，在你的新机器上运行1000，而且uid不能访问你在镜像中创build的文件。

为了得到更完整的答案，我们需要知道dcom-dev.yml的内容以及您用来构build图像的Dockerfile。
