Small changes to improve the use of falco_event_generator with falco:
- In event_generator, some actions like exec_ls won't trigger
notifications on their own. So exclude them from -a all.
- For all actions, print details on what the action will do.
- For actions that won't result in a falco notification in containers,
note that in the output.
- The short version of --once wasn't working, fix the getopt.
- Explicitly saying -a all wasn't working, fix.
- Don't rely on an external ruleset in the nodejs docker-compose
demo--the built in rules are sufficient now.
Simple docker-compose environment that starts a simple express server
with a poorly-designed /api/exec/<cmd> endpoint that executes arbitrary
commands, and uses falco to detect running bash.
