# This build script is for running the Jenkins builds using Docker.
#
# It expects a few variables which are part of Jenkins build job matrix:
#   target = barreleye|palmetto|qemu
#   distro = fedora|ubuntu|ubuntu:14.04|ubuntu:16.04
#   obmcdir = <name of OpenBMC src dir> (default openbmc)
#   WORKSPACE = <location of base OpenBMC/OpenBMC repo>
#   BITBAKE_OPTS = <optional, set to "-c populate_sdk" or whatever other
#                   BitBake options you'd like to pass into the build>

# Trace bash processing. Set -e so when a step fails, we fail the build
set -xeo pipefail
