docker 上的未知 blob 推送到 gcp

Question

我有一个在 GCP 云构建上运行的 CI/CD 构建系统。它在码头推送时偶尔会失败，并出现错误：“未知的斑点”（见下文）。重新运行失败的作业以成功结果结束。

CI/CD 是一个运行 shell 脚本的 Google CloudBuild 作业。shell 脚本运行 docker build，然后运行 ​​docker Push，因此构建后的镜像在本地可用。

docker build -f Dockerfile -t gcr.io/XXX/YYY/ZZZ/test:latest-stage1
docker push gcr.io/XXX/YYY/ZZZ/test:latest-stage1

有任何想法吗？也许我可以添加一些额外的命令来打印一些调试信息以供下次发生？

Pushing image gcr.io/XXX/YYY/ZZZ/test:latest-stage1
The push refers to repository [gcr.io/XXX/YYY/ZZZ/test]
