After you create and deploy your Cloud Run function, you can set your function to execute in response to various scenarios by specifying a trigger. This page provides an overview of the triggers supported by Cloud Run functions.
Types of triggers
By default, all functions deployed on Cloud Run are
Cloud Run source-deployed services
that have an HTTP endpoint (run.app URL). If you previously created a function
with the gcloud functions command or the
Cloud Functions v2 API, by default, the function
has a cloudfunctions.net HTTP endpoint.
