# balena-supervisor automated build
|
|
#
|
|
# Required variables:
|
|
# * ARCH
|
|
# * TAG
|
|
#
|
|
# Optional variables:
|
|
# * PUSH_IMAGES
|
|
# * CLEANUP
|
|
# * ENABLE_TESTS
|
|
# * MIXPANEL_TOKEN: default key to inject in the supervisor image
|
|
# * EXTRA_TAG: when PUSH_IMAGES is true, additional tag to push to the registries
|
|
#
|
|
# Builds the supervisor for the architecture defined by $ARCH.
|
|
# Will produce and push an image tagged as balena/$ARCH-supervisor:$TAG
|
|
#
|
|
# It pulls intermediate images for caching, if available:
|
|
# balena/$ARCH-supervisor-node:$TAG
|
|
#
|
|
# In all of these cases it will use "master" if $TAG is not found.
|
|
#
|
|
# If PUSH_IMAGES is "true", it will also push the supervisor and intermediate images (must be logged in to dockerhub)
|
|
# to the docker registry.
|
|
# If CLEANUP is "true", all images will be removed after pushing - including any relevant images
|
|
# that may have been on the host from before the build, so be careful!
|
|
# If ENABLE_TESTS is "true", tests will be run.
|
|
#
|
|
# Requires docker >= 17.05, and make.
|
|
