Question

我无法使用拆分运行状况检查部署App Engine Flex Python项目。

我启用了健康检查：

$ gcloud beta app describe
...
featureSettings:
  splitHealthChecks: true

使用docs作为模型，我的app.yaml有：

readiness_check:
  path: '/health_check'
  check_interval_sec: 5
  timeout_sec: 4
  failure_threshold: 2
  success_threshold: 2
  app_start_timeout_sec: 600

liveness_check:
  path: '/health_check'
  check_interval_sec: 30
  timeout_sec: 4
  failure_threshold: 2
  success_threshold: 2

但是当我部署时，由于以下错误而失败：

  File "/env/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 515, in spawn_worker
    worker.init_process()
  File "/env/local/lib/python2.7/site-packages/gunicorn/workers/gthread.py", line 109, in init_process

  File "/env/local/lib/python2.7/site-packages/google/appengine/api/appinfo_includes.py", line 82, in ParseAndReturnIncludePaths
    appyaml = appinfo.LoadSingleAppInfo(appinfo_file)

    raise yaml_errors.EventError(e, event_object)
EventError: Unexpected attribute 'failure_threshold' for object of type ReadinessCheck.

我正在关注文档，所以我不确定为什么会在这里触发错误。

我唯一能想到的是我的'网站套餐'可能已经过时了？我不相信我的Docker应该安装任何google/appengine/库，但我不知道我可能做错了什么。

所以上述故障情况似乎是gcr.io/google_appengine/python-compat-multicore泊坞窗图片过时造成的。

github与最新的python文件保持同步，但相关的Docker镜像从未重建过。

我已经修复了这个特殊错误，通过检查github并自己重建docker镜像，并将我的appengine flex内容指向我自己的父内置图像。

（我现在有一个单独的问题，将拆分的健康检查发送到默认路径，并且它不允许我覆盖路径。我已经将其作为Google云问题跟踪器中的错误提交。但至少上述问题是现在为我解决了）
