- Automated builds drop SDK and binary packages into gs://builds.developer.core-os.net/ and the new download URL is http://builds.developer.core-os.net/ (COREOS_DEV_BUILDS) - Change default upload path to gs://users.developer.core-os.net/ for misc developer builds. Official builds go elsewhere and will just be configured in buildbot/jenkins so some COREOS_OFFICIAL stuff is gone. - Automated builds of images go to a private bucket, gs://builds.release.core-os.net which later gets copied to gs://alpha.release.core-os.net and friends by core_promote.

This script is used to build a CoreOS image. CoreOS comes in many
|
|
different forms. This scripts can be used to build the following:
|
|
|
|
prod - Production image for CoreOS. This image is for booting.
|
|
dev - Developer image. Like base but with additional developer packages.
|
|
container - Developer image with single filesystem, bootable by nspawn.
|
|
|
|
Examples:
|
|
|
|
build_image --board=<board> dev prod - builds developer and production images.
