通过 CloudBuilder 更新图像标签以提交 SHA 的最佳方法是什么？

Question

我有一个deployment.yaml含有部署3个容器+ LB服务和cloudbuild.yaml含步骤建集装箱图像每一次有新的承诺一定的分支上到位桶混帐回购协议。

一切正常，除了每当有新映像版本（我在部署中使用 :latest 标记）时我的部署都不会更新这一事实，为了改变这一点，我明白我的部署映像应该使用一些独特的东西，而不是 :latest，例如作为 git commit SHA。

问题： 我不确定如何在 GCB CI 过程中执行图像声明更新以包含新的提交 SHA。

Answer 1

通过在部署中使用图像标记或 URI 变量并在构建时用 sed 替换它们找到了解决方案。
