This is a single command line executable meant to be triggerred from within make or make like script, which automates creation of AWS lambda python artifacts, and AWS lambda layers.
- build inside docker emulating lambda environment, with target python runtime
- precompile .pyc files, for faster cold starts
- support build-only-if-changed
- result zip file hash will remain identical between builds (important when infrastructure as code decides wether to update lambda / layer, since previous build was not on same machine)
