git - 在 GitLab CI 下的 Docker Compose 中从 git 构建时出现 "error initializing submodules"

Question

我最近更改了我的 docker-compose.yml 中的一个项目在 GitLab CI 中使用 Git 存储库(通过 HTTP，而不是 HTTPS 或 SSH)而不是相对路径。

这在我的本地机器上运行良好，如果我以自己的身份登录 CI 服务器。

当它在 GitLab 下运行时，它会到达 docker-compose build步骤并退出并出现错误(此处显示启用了 CI_DEBUG_TRACE 和 --verbose 上的 docker-compose 标志):

我关注了 GitLab documentation on submodules并没有运气。

据我所知，项目中甚至没有任何子模块是由 git 构建的。

如果有帮助，这里是 docker-compose.yml 的问题服务:

cas:
  build:
    context: http://<our gitlab url>/gitlab/docker/rubycas-server-docker.git
  depends_on:
    - "ldap"
  networks:
    - test-net
  ports:
    - "8080:8080"

以及从 git 中提取的项目的 Dockerfile(在我进行故障排除时添加了子模块行，似乎没有帮助):

FROM ruby:2.1.5

# Repo dependencies
RUN apt-get update && apt-get -y install git sqlite3

# Code
RUN git clone https://github.com/rubycas/rubycas-server.git /rubycas-server/
COPY config.yml /rubycas-server/

WORKDIR /rubycas-server/

# Pull submodules
RUN git submodule sync --recursive && git submodule update --init --recursive

# Need to downgrade to Ruby 2.1.5 but latest rack-test requires 2.2.2
RUN sed -i 's/"rack-test"/"rack-test", "~> 0\.7\.0"/' rubycas-server.gemspec

# Ruby dependencies (include database adapter)
RUN gem install bundler
RUN bundle install && bundle add sqlite3

# Create the database file and log - they're empty
RUN sqlite3 cas.db ''
# RUN touch cas.log

CMD bundle exec rubycas-server -c config.yml

实际解决方案

服务器使用的是非常旧版本的 git。手动将 git 包升级到最新版本解决了这个问题并允许我使用最新的 docker-ce版本。

这似乎是 docker-ce 的最新边缘版本的问题。 .我从 18.02.0.ce-1.el7.centos 降级至17.12.1.ce-1.el7.centos通过禁用 docker-ce-edge repo并重新安装，问题就解决了。
