我在我的 Rails 项目中使用docker-api 。

我需要使用我的自定义图像创建容器。

.gitlab-ci.yml:

  variables:
  DOCKER_DRIVER: overlay2
  DOCKER_TLS_CERTDIR: ""
  DB_HOST: postgres
  RAILS_ENV: test

build:
  stage: build
  image: docker:19.03.0 
  services:
    - docker:19.03.0-dind
  script:
    - docker build -t my_image docker/my_image/.

rspec:
  image: ruby:2.6.3
  services:
    - postgres:10.1
    - docker:19.03.0-dind
  script:
    - export DOCKER_URL=tcp://docker:2375
    - cp config/database.yml.gitlab_ci config/database.yml
    - gem install bundler
    - bundle install
    - rails db:create
    - rails db:migrate
    - rspec 

我有错误:

Failure/Error:
  container = Docker::Container.create('Cmd' => ['tail', '-f', '/dev/null'],
                                            'Image' => 'my_image')

Docker::Error::NotFoundError:
  No such image: my_image:latest

如何解决这个问题?

您指定的每个作业都将使用不同的dind. 您可能需要从第一个作业推送图像并将其拉入第二个作业。

  image = Docker::Image.build_from_dir('./docker/my_image/.')
  image.tag('repo' => 'my_image', 'tag' => 'latest', force: true)
