Support Github webhook secret

[shinebayar-g]

Hi, is the Github webhook secret supported? I didn't find anything in docs. If not, is it possible to support the Github webhook secrets?

Not supported but seems straightforward to add. Need to add a check here https://github.com/keel-hq/keel/blob/master/pkg/http/github_webhook_trigger.go#L233 where we get request bytes. They have instructions for ruby (https://docs.github.com/en/developers/webhooks-and-events/securing-your-webhooks#validating-payloads-from-github) but Go's std lib provides sha1 digest check as well.

Looks like Github is introducing new docker registry because of current one doesn't even allow pull public images without logging into github.
