run.sh

#!/bin/bash
# Start container and start process inside container.
#
# Example:
#   ./run.sh            Start a sh shell inside container.
#   ./run.sh ls -la     Run `ls -la` inside container.
#
# Calls to `make` are intercepted and the "O=/buildroot_output" is added to
# command. So calling `./run.sh make savedefconfig` will run `make
# savedefconfig O=/buildroot_output` inside the container.
#
# Example:
#   ./run.sh make       Run `make O=/buildroot_output` in container.
#   ./run.sh make docker_python2_defconfig menuconfig
#                       Build config based on docker_python2_defconfig.
#
# When working with Buildroot you probably want to create a config, build
# some products based on that config and save the config for future use.
# Your workflow will look something like this:
#
# ./run.sh make docker_python2_defconfig defconfig
# ./run.sh make menuconfig
# ./run.sh make BR2_DEFCONFIG=/root/buildroot/external/configs/docker_python2_defconfig savedefconfig
# ./run.sh make
