Failed to set up the webhook in Github for gitwebhook-go sample #1312
Description
I followed the tutorial at https://github.com/knative/docs/tree/master/docs/serving/samples/gitwebhook-go.
I used the GKE as the Kube backend. After configuring the domain and the static IP, I still failed to create a valid webhook available to receive the payload successfully.
SSL validation option is only available when we use HTTPS protocol, like https://<domain>, and it is not available for HTTP protocol, like http://<domain> as the payload URL.
No matter I used https://<domain> or http://<domain>, I failed to get successful response from the webhook, when I delivered any payload to the URL http://<domain>.
It popped up with "405 method not allowed", when I run "curl -H "Host: gitwebhook.default.<domain>.com" http://${IP_ADDRESS}"
