Photon OS Build Help Guide

Overview:

This script provides various build options for Photon OS.
Each option allows you to perform different build tasks, ranging from building
individual packages to creating entire ISO images.

Usage:

Run the script using the following command format:
    make [options] (equivalent to python3 build.py -t <opt>)
    python3 build.py [options]

Options:

Here are the available options you can use with the script:

- -h, --help
  - Displays the help message and exits.

- -c, --config CONFIG
  - Specifies the path to the build configuration file.
  - Default is 'build-config.json'.

- -t, --target TARGET
  - Specifies the build target.
  - Possible values include:
    - 'all': Build all components.
    - 'all-images': Build AMI, GCE, Azure, and OVA images.
    - 'basic-iso': Build the basic ISO.
    - 'check-packages': Run package self-tests (%check).
    - 'check-pre-reqs': Check prerequisites to start the Photon build.
    - 'clean': Clean everything.
    - 'clean-chroot': Clean the chroot environment.
    - 'clean-stage-for-incremental-build': Remove upward dependencies and build incrementally.
    - 'create-repo': Create repository data.
    - 'extra-packages': Build additional packages like Chromium.
    - 'generate-yaml-files': Generate the OSS YAML file.
    - 'iso': Build the ISO image.
    - 'k8s-docker-images': Build Kubernetes Docker images.
    - 'minimal-iso': Build the minimal ISO.
    - 'ostree-repo': Build the OSTree repository.
    - 'packages': Build all packages.
    - 'packages-basic': Build packages for the basic ISO.
    - 'packages-docker': Build packages for the Docker image.
    - 'packages-initrd': Build initrd packages.
    - 'packages-minimal': Build packages for the minimal ISO.
    - 'packages-rt': Build packages for the RT ISO.
    - 'photon-docker-image': Build the Photon Docker image.
    - 'rt-iso': Build the RT ISO.
    - 'sources-cached': Create the stage directory hierarchy.
    - 'src-iso': Build the source ISO.
    - 'tool-chain-stage1': Build stage 1 packages.
    - 'tool-chain-stage2': Build stage 2 packages.

Environment Variables:

Customize your build process using these environment variables:

BASE_COMMIT
- Used while invoking spec checker and while cleaning stage for incremental build
- This commit is considered as the commit to build Photon from.

BUILD_DBGINFO_RPM
- 1/0 to enable/disable debuginfo rpm build

BUILD_EXTRA_PKGS
- Build extra/special package like Chromium

BUILD_SRC_RPM
- 1/0 to enable/disable src rpm build

BUILDDEPS
- Generate BuildDependencies.json during package build

ACVP_BUILD
CANISTER_BUILD
KAT_BUILD
- All three of the above configs used while building kernels

CONFIG
- Config file to use

DOCKER_ENV
- Skips docker pre checks if file given here is present

IMG_NAME
- Which image to build, can be ova, azure, gce

INPUT_PHOTON_BUILD_NUMBER

LOGLEVEL
- Info by default, set to debug for verbose logging

PH_DOCKER_IMAGE_URL
- Docker image url to import from if needed by builder

PHOTON_BUILD_NUM
- Commit ID of Photon repo to build

PHOTON_CACHE_PATH
PHOTON_SOURCES_PATH
PHOTON_PUBLISH_RPMS_PATH
PHOTON_PUBLISH_XRPMS_PATH
- All four configs above are cached photon packages path, source tarball path, publish & publishX rpms cached paths
- Pre existing files will be used from these locations during build process.

PHOTON_DOCKER_IMAGE
- Photon docker image to use while doing package builds
- May or may not be used based on host's capabilities

PHOTON_PKG_BLACKLIST_FILE
- Packages to be skipped while generating OSS yaml

PHOTON_PULLSOURCES_CONFIG

PHOTON_RELEASE_VER
- Release version of Photon

PKG_BUILD_OPTIONS
- Package specific additional build options
- Refer: common/data/pkg_build_options.json

POI_IMAGE
- Photon offline installer (POI) container image to use

RESUME_BUILD
- Resume building of package without clearing chroot

RPMCHECK
- Run %check of given package

THREADS
- Number of packages to build in parallel, doesn't work like `make -j`

CHROOT_ENV_SETUP_SCRIPT
- Script's absolute path to customize chroot build environment

Examples:

Build Everything:

    sudo make all THREADS=4

Build ISO Variants:

    sudo make iso THREADS=4
    sudo make minimal-iso THREADS=4
    sudo make basic-iso THREADS=4
    sudo make rt-iso THREADS=4
    sudo make src-iso THREADS=4

Build Packages:

    sudo make <pkg-name> THREADS=4 LOGLEVEL=debug
    sudo make packages THREADS=4
    sudo make packages-minimal THREADS=4
    sudo make packages-basic THREADS=4
    sudo make packages-rt THREADS=4
    sudo make packages-initrd THREADS=4
