【问题描述】：
我正在尝试为我的 python 应用程序实现 flask-healthz (https://pypi.org/project/flask-healthz/) 以获得活性和红色探测的回报。但不知何故，它对我不起作用。下面是我的代码 sn-p ：
from flask import Flask
from flask_healthz import healthz
from flask_healthz import HealthError
def printok():
print("Everything is fine")
app = Flask(__name__)
app.register_blueprint(healthz, url_prefix="/healthz")
def liveness():
try:
printok()
except Exception:
raise HealthError("Can't connect to the file")
def readiness():
try:
printok()
except Exception:
raise HealthError("Can't connect to the file")
HEALTHZ = {
"live": "yourapp.checks.liveness",
"ready": "yourapp.checks.readiness",
}
@app.route("/")
def hello():
return "Hello World!"
if __name__ == "__main__":
app.run(host='0.0.0.0', port=5000)
代码的输出如下所示：
(app-root) curl http://localhost:5000/
127.0.0.1 - - [02/Jun/2021 01:02:56] "GET / HTTP/1.1" 200 -

是不是我做错了什么。我尝试在 Openshift 中很好地运行相同的程序，但没有成功。
如果有一些可行的例子，我会很高兴。
【问题讨论】：
-
你有你的 'yourapp.checks.liveness' 和 'yourapp.checks.readiness' 或者这只是示例的复制粘贴？
-
对于 openshift 部署，在我的 deployment.yaml 中，我将容器的名称设置为 yourapp。为了在本地 python 终端中运行这个脚本，这只是一个复制粘贴，因为本地没有 yourapp
