like some others we also had a monorepo that we wanted to build with drone. We have create a drone plugin that walks up a directory tree and combines all drone ci files to a single multi-machine build.
To create the individual .drone.yml files we use Drone’s jsonnet plugin and a Makefile:
TARGETS = $(shell find -name .drone.json) LINKS = $(TARGETS:.json=.jsonnet) DRONE = $(TARGETS:.json=.yml) all: links drone clean: rm $(LINKS) $(DRONE) || true links: $(LINKS) $(LINKS): ln -s $(dir $(abspath $(lastword $(MAKEFILE_LIST))))/.drone.jsonnet [email protected] drone: $(DRONE) $(DRONE): drone jsonnet --source=$(@:.yml=.jsonnet) [email protected]
In each directory we want a
.drone.yml we place a
.drone.json with some configuration options. The
.drone.jsonnet will be run against each of the json files.
