Gitlab DID缓存无法正常工作

我在我的本地服务器上安装了Gitlab的Omnibus，在另一台服务器上安装了执行CI任务的gitlab-runner .

在我的管道中，我有一个Job，它使用Docker In Docker和codeclimate检查代码质量 .

问题是它非常慢（20分钟），因为每次下载并提取codeclimate的docker镜像 .

docker pull codeclimate/codeclimate

我试图配置gitlab-ci缓存但没有改变 .

cache:
    paths:
      - build
      - .gradle
    untracked: true

stage: reports
  image: docker:latest
  before_script: []
  variables:
    DOCKER_DRIVER: overlay2
  services:
    - docker:dind
  script: 
    - docker info
    - docker pull codeclimate/codeclimate
    - mkdir -pv build/reports/codequality
    - cp .codeclimate.yml src
    - docker run --env CODECLIMATE_DEBUG=1 --env CODECLIMATE_CODE="$PWD/src" --volume "$PWD/src":/code --volume /var/run/docker.sock:/var/run/docker.sock --volume /tmp/cc:/tmp/cc codeclimate/codeclimate validate-config
    - docker run --env CODECLIMATE_DEBUG=1 --env CODECLIMATE_CODE="$PWD/src" --volume "$PWD/src":/code --volume /var/run/docker.sock:/var/run/docker.sock --volume /tmp/cc:/tmp/cc codeclimate/codeclimate analyze -f html > build/reports/codequality/codequality.html
    - docker run --env CODECLIMATE_DEBUG=1 --env CODECLIMATE_CODE="$PWD/src" --volume "$PWD/src":/code --volume /var/run/docker.sock:/var/run/docker.sock --volume /tmp/cc:/tmp/cc codeclimate/codeclimate analyze -f json > build/reports/codequality/raw_codequality.json
    - cat build/reports/codequality/raw_codequality.json
    - cat build/reports/codequality/raw_codequality.json | docker run -i stedolan/jq -c 'map({check_name,fingerprint,location})' > build/reports/codequality/codequality.json
    - rm src/.codeclimate.yml

这是我的config.toml

[[runners]]
  name = "DockerBuilder"
  url = "http://gitlab.mycompany.com"
  token = "mytoken"
  executor = "docker"
  [runners.docker]
    tls_verify = false
    image = "docker:latest"
    privileged = true
    disable_cache = false
    volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock", "/etc/default/docker:/etc/default/docker", "/etc/docker/daemon.json:/etc/docker/daemon.json"]
    extra_hosts = ["localhost:172.X.X.X"]
    shm_size = 0
  [runners.cache]
