kubectl 从 gitlab 未经授权拉取镜像：HTTP Basic：访问被拒绝

我正在尝试配置 gitlab ci 以将应用程序部署到谷歌计算引擎。我已成功将映像推送到 gitlab 存储库，但在应用 kubernetes 部署配置后，我在 kubectl 描述 pod 中看到以下错误：

Failed to pull image "registry.gitlab.com/proj/subproj/api:v1": rpc error: code = 2 
desc = Error response from daemon: {"message":"Get https://registry.gitlab.com/v2/proj/subproj/api/manifests/v1: unauthorized: HTTP Basic: Access denied"}

这是我的部署 gitlab-ci 工作：

docker:
  stage: docker_images
  image: docker:latest
  services:
    - docker:dind
  script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
    - docker build -t registry.gitlab.com/proj/subproj/api:v1 -f Dockerfile .
    - docker push registry.gitlab.com/proj/subproj/api:v1
  only:
    - master
  dependencies:
  - build_java

k8s-deploy:
  image: google/cloud-sdk
  stage: deploy
  script:
    - echo "$GOOGLE_KEY" > key.json # Google Cloud service account key
    - gcloud auth activate-service-account --key-file key.json
    - gcloud config set compute/zone us-central1-c
    - gcloud config set project proj
    - gcloud config set container/use_client_certificate True
    - gcloud container clusters get-credentials proj-cluster
    - kubectl delete secret registry.gitlab.com  --ignore-not-found
    - kubectl create secret docker-registry registry.gitlab.com --docker-server=https://registry.gitlab.com/v1/ --docker-username="$CI_REGISTRY_USER" --docker-password="$CI_REGISTRY_PASSWORD" --docker-em[email protected] /cdn-cgi/l/email-protection
    - kubectl apply -f  cloud-kubernetes.yml

这是 cloud-kubernetes.yml：

apiVersion: v1
kind: Service
metadata:

    service.alpha.kubernetes.io/tolerate-unready-endpoints: "true"

我已关注本文 https://about.gitlab.com/2016/12/14/continuous-delivery-of-a-spring-boot-application-with-gitlab-ci-and-kubernetes/

有一个解决方法，可以将图像推送到 google 容器注册表，然后从 gcr 中提取，而不安全。我们可以使用 gcloud cli 将图像推送到 gcrjson 令牌文件 https://cloud.google.com/container-registry/docs/advanced-authentication. So .gitlab-ci.yaml可能看起来像：

docker:
  stage: docker_images
  image: docker:latest
  services:
    - docker:dind
  script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
    - docker build -t registry.gitlab.com/proj/subproj/api:v1 -f Dockerfile .
    - docker push registry.gitlab.com/proj/subproj/api:v1
    - docker tag registry.gitlab.com/proj/subproj/api:v1 gcr.io/proj/api:v1
    - docker login -u _json_key -p "$GOOGLE_KEY" https://gcr.io
    - docker push gcr.io/proj/api:v1
  only:
    - master
  dependencies:
  - build_java

k8s-deploy:
  image: google/cloud-sdk
  stage: deploy
  script:
    - echo "$GOOGLE_KEY" > key.json # Google Cloud service account key
    - gcloud auth activate-service-account --key-file key.json
    - gcloud config set compute/zone us-central1-c
    - gcloud config set project proj
    - gcloud config set container/use_client_certificate True
    - gcloud container clusters get-credentials proj-cluster
    - kubectl apply -f cloud-kubernetes.yml

cloud-kubernetes.yaml 中的图像应该是：

gcr.io/proj/api:v1
