4# This build script is for running the QEMU build as a container with the
5# option of launching the container with Docker or Kubernetes.
6#
7###############################################################################
8#
9# Script Variables:
10#  build_scripts_dir  The path of the openbmc-build-scripts directory.
11#                     Default: The directory containing this script
12#  http_proxy         The HTTP address of the proxy server to connect to.
13#                     Default: "", proxy is not setup if this is not set
14#  qemu_dir           Path of the directory that holds the QEMU repo, if none
15#                     exists will clone in the OpenBMC/QEMU repo to WORKSPACE.
16#                     Default: "${WORKSPACE}/qemu"
17#  WORKSPACE          Path of the workspace directory where some intermediate
18#                     files and the images will be saved to.
19#                     Default: "~/{RandomNumber}"
20#
21# Docker Image Build Variables:
22#  build_dir          Path of the directory that is created within the docker
23#                     container where the build is actually done. Done this way
24#                     to allow NFS volumes to be used as the qemu_dir.
25#                     Default: "/tmp/qemu"
26#  img_name           Defaults to qemu-build with the arch as its tag, can be
27#                     changed or passed to give a specific name to created image
28#
29# Deployment Variables:
30#  launch             ""|job|pod
31#                     Leave blank to launch via Docker if not using kubernetes
32#                     to launch the container.
33#                     Job lets you keep a copy of job and container logs on the
34#                     api, can be useful if not using Jenkins as you can run the
35#                     job again via the api without needing this script.
36#                     Pod launches a container which runs to completion without
37#                     saving anything to the api when it completes.
