kas-build - kas build plugin

kas build [-h] [--skip STEP] [--force-checkout] [--update] [-k]


          [--target TARGET] [-c TASK] [--provenance {true,mode=min,mode=max}]


          [config] [extra_bitbake_args ...]


Checks out all necessary repositories and builds using bitbake as specified in the configuration file.

This plugin implements the kas build command.

When this command is executed, kas will checkout repositories, setup the build environment and then invoke bitbake to build the targets selected in the chosen config file.

When running with --provenance <true|mode=...> kas will generate an provenance attestation for the build. The attestation will be stored in attestation/kas-build.provenance.json in the build directory. For details about provenance, see the build attestation chapter.

NOTE:

In provenance mode, the command returns with a non-zero exit code in case no artifact is found for at least one entry.


Positional Arguments

Config file(s), separated by colon. Using .config.yaml in KAS_WORK_DIR if none is specified.
Extra arguments to pass to bitbake (typically requires separation via '--')

Possible choices: setup_dir, setup_home, init_setup_repos, repo_setup_loop, finish_setup_repos, repos_checkout, repos_check_signatures, repos_apply_patches, setup_environ, write_bbconfig
