kubernetes startup probe failed when deploying over Azure Kubernetes Services

Question

I have asp.net core web api app where I have implemented health checks when we deployed the app to Azure Kubernetes Services and the startup probe gets failed.

startupProbe: httpGet: path: /health/startup port: 32243 failureThreshold: 25 periodSeconds: 10

I can see that internally it's hit the endpoint with IP address overs http.

Startup probe failed: Get "http://10.22.148.185:32243/health/startup": dial tcp 10.22.148.185:32243: connect: connection refused

When I removed startup probe from YAML definition, then the startup endpoint is working as expected, here I am checking with FQDN over IP address

https://my-dns.com:32243/health/startup

What I am missing here? Thanks.

what `scheme` value do you use for the httpGet startupProbe? it seems that you need to use `https` instead of `http`. — Raymond Hartoyo, Dec 07 '21 at 10:06
Yes, right sir, later I figured out that :) Thanks for your answer — user584018, Dec 07 '21 at 10:11

You can use https instead of http for the httpGet.scheme value of the startupProbe.

Thanks @Raymond. one question, can you suggest how to test liveness probe for asp.net web api app? please check my question here, https://stackoverflow.com/questions/70262289/how-to-simulate-asp-net-web-api-app-to-a-deadlock-or-hung-state – user584018 Dec 07 '21 at 15:16
