来自gitlab的kubectl拉图像未经授权:HTTP基本:访问被拒绝 [英] kubectl pull image from gitlab unauthorized: HTTP Basic: Access denied

问题描述

我正在尝试配置gitlab ci以将应用程序部署到Google计算引擎.我已经成功将映像推送到gitlab存储库，但是在应用kubernetes部署配置后，我在kubectl描述pod中看到以下错误:

I am trying to configure gitlab ci to deploy app to google compute engine. I have succesfully pushed image to gitlab repository but after applying kubernetes deployment config i see following error in kubectl describe pods:

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:

Here is my deployment gitlab-ci job:

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-email=[e-mail]
    - kubectl apply -f  cloud-kubernetes.yml

这是cloud-kubernetes.yml:

and here is cloud-kubernetes.yml:

apiVersion: v1
kind: Service
metadata:
  annotations:
    service.alpha.kubernetes.io/tolerate-unready-endpoints: "true"

        imagePullPolicy: Always
        env:
          - name: SPRING_PROFILES_ACTIVE
            value: "cloud"
        ports:
        - containerPort: 8082
      imagePullSecrets:
        - name: registry.gitlab.com

我已遵循推荐答案

有一种解决方法，可以将图像推送到Google容器注册表中，然后在没有安全性的情况下将其从gcr中拉出.我们可以使用 json令牌文件将图像推送到不带gcloud cli的gcr.因此.gitlab-ci.yaml可能看起来像:

There is workaround, image could be pushed to google container registry, and then pulled from gcr without security. We can push image to gcr without gcloud cli using json token file. So .gitlab-ci.yaml could look like:

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中的图像应为:

And image in cloud-kubernetes.yaml should be:

gcr.io/proj/api:v1

gcr.io/proj/api:v1
