You can run your Lambdas from local directories using the -v arg with docker run. You can run them in two modes: as a single execution, or as an API server that listens for invoke events. The default is single execution mode, which outputs all logging to stderr and the result of the handler to stdout. You mount your (unzipped) lambda code at /var/task and any (unzipped) layer code at /opt, and most runtimes take two arguments – the first for the handler and the second for the event, ie:
