所以我试图在gitlab中设置容器扫描，我尝试了很多方法，但似乎都不起作用，我错过了什么？
我的gitlab版本是：GitLab Community Edition 12.9.4
机器中的gitlab-runner为：Version: 12.10.2
这是我的.gitlab-ci.yml

variables:
  vulnerable_tag: vulnerable
  non_vulnerable_tag: non_vulnerable
  IMAGE_NAME: test
  CLAIR_OUTPUT: High 

stages:
    - build
    - test

build:
  image: docker
  stage: build
  variables:
    IMAGE_NAME: test
    IMAGE_TAG: $CI_REGISTRY_IMAGE/$CI_COMMIT_REF_SLUG:$CI_COMMIT_SHA
  script:
    - uname -a
    - docker build -t $IMAGE_NAME .
    - docker run -d -p 80:80 $IMAGE_NAME 
    - docker ps
    - curl localhost
    - mkdir output
    - echo $IMAGE_NAME"/"$CI_COMMIT_REF_SLUG":"$CI_COMMIT_SHA >> output/file.txt
  tags:
    - testingtag
#  artifacts:
#    paths: 
#      - output/

stop_container:
  stage: test
  script:
    - docker stop $(docker ps -q)

是一个简单的nginx容器，它只显示一个普通索引。
我所尝试的（.gitlab-ci.yml中的所有内容）都不起作用

include:
  - template: Container-Scanning.gitlab-ci.yml

这就是文档中所说的，也是它应该如何工作的，但是它抛出了一个错误This GitLab CI configuration is invalid: Included fileContainer-Scanning.gitlab-ci.ymlis empty or does not exist!

include:
 - remote: 'https://gitlab.com/gitlab-org/gitlab/-/raw/master/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml'

这不会抛出错误，但什么也不做。（链接与Container-Scanning.gitlab-ci.yml相同，但为明文）
最后，将Container-Scanning.gitlab-ci.yml的内容添加为作业

# Read more about this feature here: https://docs.gitlab.com/ee/user/application_security/container_scanning/

container_scanning:
  stage: test

  variables:
    # By default, use the latest clair vulnerabilities database, however, allow it to be overridden here with a specific image

    GIT_STRATEGY: none
  allow_failure: true
  services:
    - name: $CLAIR_DB_IMAGE
      alias: clair-vulnerabilities-db
  script:
    - /analyzer run
  artifacts:
    reports:
      container_scanning: gl-container-scanning-report.json

    - if: $CONTAINER_SCANNING_DISABLED
      when: never
    - if: $CI_COMMIT_BRANCH &&

CI跳过此作业，因为它不存在
