如何在Gitlab CI中为rails项目使用缓存？

Question

我一直在尝试利用Gitlab Ci的缓存为我的ruby on rails应用程序,但到目前为止还没有运气,我的应用程序是使用共享运行程序,也许这就是问题？

这是我的内容 .gitlab-ci.yml

services:
  - postgres:latest

rspec:
  stage: test
  script:
    - apt-get update -qy
    - apt-get install -y nodejs
    - gem install bundler
    - bundle check --path vendor/bundle || bundle install --path vendor/bundle --jobs $(nproc)
    - cp config/database.gitlab-ci.yml config/database.yml
    - RAILS_ENV=test bundle exec rake db:create db:schema:load
    - bundle exec rspec
  cache:
    paths:
      - vendor/bundle
  tags:
    - ruby
    - postgres

当我的测试运行时,我确实看到跑步者检查缓存内容,但它从未恢复它:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 30ea1b5... Fix width of tables contained in table-scroll divs
Checking cache for rspec/master...

$ apt-get update -qy

当构建即将完成时,我确实看到它试图创建缓存:

Creating cache rspec/master...
vendor/bundle: found 8917 matching files

有任何想法吗？

在我发布这个问题几周后，缓存实际上开始正常工作，不需要更改我的配置。我相信这与 gitlab 推出的更新有关。
