opentrons-build.sh

#!/bin/bash
# This script is the top level build script for devs to use when doing manual
# builds so they don’t have to remember the multiple docker steps or arguments
# to bind mount the buildroot source.
#
# The script pipes its arguments to the eventual docker run invocation that
# runs buildroot’s make. The final argument is the argument to buildroot’s
# makefile; all others are inserted into the docker run command. For instance,
# to build a specific defconfig you could do
# ./opentrons-build.sh raspberrypi3_defconfig
# And to just get a shell in the docker container you could do
# ./opentrons-build.sh -ti --entrypoint /bin/bash ""
# The final empty quote marks are necessary for the script to correctly parse
# the arguments.

# Note also that if there are no arguments, the script will do the proper
# sequence of invocations to build buildroot from a fresh clone (e.g. two
# make invocations, one for defconfig and one for build); when arguments
# are provided, it will run the docker container once with the arguments
