Google Cloud Build - source-context.json SHA不匹配。

Posted 2021-03-19

我有一个Python 3项目，我在Google AppEngine Standard上托管。直到几天前，我还能正常部署（就在我2019年7月做了初始设置后），直到几天前。现在我得到了以下响应。

starting build "abc"

Finished Step #0 - "fetcher"
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/gcs-fetcher" failed: step exited with non-zero status: 1

任何想法为什么会发生这种情况，如何解决？

P.S.我使用以下命令进行部署。

gcloud --project my-project app deploy app.yaml

答案

在与谷歌工程师交谈后(https:/issuetracker.google.comissues154588981?pli=1。)以下工作。

1. 移除 source-context.json 档案
2. 删除部署文件所在的bucket，例如gs:/staging.my-project.appspot.com。
3. 再次部署

如果你需要 source-context.json 文件，您可以按照以下步骤操作。https:/www.google.comurl?q=https:/cloud.google.comdebuggerdocssource-context&sa=D&usg=AFQjCNHMB7Dm_jISwG2AnpokQ7XN5GmLAw。
