利用 Google Artifact Repository 构建docker 镜像仓库

参考了google 官方文档
https://cloud.google.com/artifact-registry/docs/docker/store-docker-container-images

首先 enable GAR api

gcloud services enable artifactregistry.googleapis.com
gcloud services list | grep -i artifact
artifactregistry.googleapis.com      Artifact Registry API

其次创建1个docker image 仓库

gcloud artifacts repositories create my-docker-repo --repository-format=docker --location=eurepo-west2 --description=“”

用如下命令来list 已有的仓库

> gcloud artifacts repositories list
Listing items under project jason-hsbc, across all locations.ARTIFACT_REGISTRY

配置docker 的验证方法

因为之后我们需要用docker push 把镜像推送到 Google AR, 所以我们在docker的配置文件里配置docker 访问 Google AR 的验证方式。

docker 到 GAR 的验证方式有四种：

1. gcloud credential helper

配置您的 ArtifactRegistry 凭据，以便直接在 gcloud 中与 Docker 一起使用。这是最简单的身份验证方法，但可能比Standalone Docker credential helper慢

2. Standalone Docker credential helper

此选项主要用于配置您的凭据，以便在没有 Google Cloud CLI 的情况下与 Docker 一起使用。它比 gcloud 凭据帮助程序快得多，并使用应用程序默认凭据 (ADC) 自动查找环境中的凭据。

3. Access token

您可以为服务帐户生成短期访问令牌，然后使用该令牌进行密码身份验证。由于令牌的有效期仅为 60 分钟，因此它是比服务帐户密钥更安全的选择。

4. Service account key

用户管理的密钥对，可用作服务帐户的凭据。由于凭证的有效期很长，因此它是所有可用身份验证方法中最不安全的选项。

具体参考：
https://cloud.google.com/artifact-registry/docs/docker/authentication

这里选择最简单的方法1： gcloud credential helper

执行以下命令
gcloud auth configure-docker europe-west2-docker.pkg.dev

high lighted 部分请替换成你当前repo所在的region

gateman@DESKTOP-UIU9RFJ:/var/lib/jenkins/workspace/CloudRun/build@2$ gcloud auth configure-docker europe-west2-docker.pkg.dev
Adding credentials for: europe-west2-docker.pkg.dev
After update, the following will be written to your Docker config file located at [/home/gateman/.docker/config.json]:{"credHelpers": {"europe-west2-docker.pkg.dev": "gcloud"}
}Do you want to continue (Y/n)?  yDocker configuration file updated.

当执行完成， /home/gateman/.docker/config.json 会被updated

docker build or tag

这时你就可以用docker build or docker tag 去为你的镜像打上正确镜像地址和标签
例如

gateman@instance-2:~/Projects/spring-boot-for-cloud-run$ sudo docker build -t europe-west2-docker.pkg.dev/jason-hsbc/my-docker-repo/helloservice:0.0.1-test .
