// This file contains the logic for building our CI for Drone. The idea here is
// that we create a pipeline for all of the major tasks we need to perform
// (e.g. builds, E2E testing, conformance testing, releases). Each pipeline
// after the default builds on a previous pipeline.
// Generate with `drone jsonnet --source ./hack/drone.jsonnet --stream --format`
