Package githook adds support for git-based sources in pipeline specs. It does so by exposing an HTTP server that listens for webhook requests. This works with github's webhook API, and anything else API-compatible with their push events.
const GitHookPort = 999
GitHookPort specifies the port the server will listen on
ExternalPort provides the port used to access the service via a load balancer
NodePort provides the port used to access the service via a node
RunGitHookServer starts the webhook server
URLFromDomain provides the webhook URL given an input domain
