balena-supervisor/Makefile

# resin-supervisor Makefile
#
# If you're looking for an easy way to develop on the supervisor, check ./tools/dev/dindctl, which provides a simplified interface
# to this makefile.
#
# Build targets (require Docker 17.05 or greater):
# * supervisor (default) - builds a resin-supervisor image
# * deploy - pushes a resin-supervisor image to the registry, retrying up to 3 times
# * nodedeps, nodebuild - builds the node component, with the node_modules and src at /usr/src/app and /build (also includes a rootfs-overlay there)
# * supervisor-dind: build the development docker-in-docker supervisor that run-supervisor uses (requires a SUPERVISOR_IMAGE to be available locally)
#
# Variables for build targets:
# * ARCH: amd64/rpi/i386/armv7hf/armel/aarch64 architecture for which to build the supervisor - default: amd64
# * IMAGE: image to build or deploy - default: resin/$(ARCH)-supervisor:latest
# * MIXPANEL_TOKEN: (optional) default mixpanel key to embed in the supervisor image
# * DISABLE_CACHE: if set to true, run build with no cache - default: false
# * DOCKER_BUILD_OPTIONS: Additional options for docker build, like --cache-from parameters
#
# Test/development targets:
# * run-supervisor, stop-supervisor - build and start or stop a docker-in-docker resin-supervisor (requires aufs, ability to run privileged containers, and a SUPERVISOR_IMAGE to be available locally)
#
# Variables for test/dev targets:
# * IMAGE: image to build and run (either for run-supervisor or test-gosuper/integration)
# * SUPERVISOR_IMAGE: In run-supervisor and supervisor-dind, the supervisor image to run inside the docker-in-docker image
# * PRELOADED_IMAGE: If true, will preload user app image from tools/dev/apps.json and bind mount apps.json into the docker-in-docker supervisor
# * MOUNT_DIST: If true, mount the dist folder into the docker-in-docker supervisor
# * MOUNT_NODE_MODULES: If true, mount the node_modules folder into the docker-in-docker supervisor
# * CONTAINER_NAME: For run-supervisor, specify the container name for the docker-in-docker container (default: supervisor which produces container resinos-in-container-supervisor)
# * CONFIG_FILENAME: For run-supervisor, specify the filename to mount as config.json, relative to tools/dind/ (default: config.json)
# * DIND_IMAGE: For run-supervisor, specify the resinOS image to use (default: resin/resinos:2.12.5_rev1-intel-nuc)
