docker - Docker “Login succeeded”，但仍无法推送到GCP私有(private)注册表

我将Docker镜像推送到我的私有(private)GCP注册表时遇到问题。
我从Google Cloud Platform创建了一个具有所有者角色的新服务帐户。然后，我创建了一个服务密钥，并在Gitlab CI / CD变量的$ GCP_SERVICE_KEY变量中复制了json文件的内容(从服务帐户下载)。

这是我的 .gitlab-ci.yaml 文件:

image: python:3.6

stages:
  - push

before_script:
  - mkdir -p $HOME/.docker
  - echo "$GCP_SERVICE_KEY" >> "$HOME/.docker/config.json"

dockerpush:
  stage: push
  image: docker:stable
  services:
    - docker:dind
  script:
    - docker build --build-arg MONGODB_URI=$MONGODB_URI -t my_image_name .
    - docker login -u _json_key --password-stdin https://gcr.io < $HOME/.docker/config.json
    - docker tag my_image_name eu.gcr.io/my_project_id/my_image_name
    - docker push eu.gcr.io/my_project_id/my_image_name

当我检查控制台日志时，看到“登录成功”。但是我无法推送到我的GCP注册中心。我检查了项目ID，用户的角色，一切似乎都还好。但是，为什么我仍然看到“未经授权”的错误？

$ docker login -u _json_key -p "$GCP_SERVICE_KEY" https://gcr.io

最佳答案

您正在登录https://gcr.io，但推送到https://eu.gcr.io
将docker login命令更新为https://eu.gcr.io
