Azure Function Core Tool HTTP Trigger to HTTPS

Question

Hello,

Are there any instructions as to how to secure HTTP triggers and get them to respond on HTTPS instead?

Answer 1

Hi @Lev Goronshtein ,

Thanks for reaching out to Q&A.

It appears that you want to enforce TLS for a http triggered app running on Kubernetes.

Please refer to the following article that has the steps to enforce TLS on function app running on K8
https://thecloudblog.net/lab/enable-tls-on-http-triggered-function-app-in-kubernetes-using-keda-and-nginx/

Feel free to reach out to me if you have any queries or concerns.

Hi @Lev Goronshtein
You can enable HTTPS Only under TLS/SSL settings:
https://learn.microsoft.com/en-us/azure/app-service/configure-ssl-bindings#enforce-https
(the url is for web app but that is also available under function app)
You may need to restart the Function app after changing this setting. this will redirect to the https url of the function

If you need for local testing:

@Bruno Lucas ,

Sorry i wasnt more specific but these HTTP triggers are running in a K8s cluster on prem. This is using Azure Functions Core Tools to deploy them.
