FaaS - Failure as a Service

Provides many misbehavior cases as a Service.

General configuration

--port - port to listen on
--host - host to listen on (defaults to 0.0.0.0)
--config-file - application config file
--log-directory - application log directory (defaults to cwd)
--debug - print debug info
--start-delay-seconds start application after N seconds (defaults to 0)
--crash - crash application before starting socket
--ignore-signal - specify OS signal to be ignored in numeric format
--require-authentication - enforce token base authentication - if set, --config-file is required as well

delay - wait N seconds before processing a request - this can simulate time-consuming operations (defaults to 1)
return_status_code - what status code should be returned after processing a request

Displays various informations about current server process.

Kill application and let it be restarted. If crash_loop is set, during next startup, app will restart again. Parameters

exit_code - exit code number to exit with (defaults to 0)
crash_loop - sets crash loop for this process by creating file $PWD/crash_loop_${CRASH_LOOP_ENV_VAR} - during startup, application will crash before opening listen socket if this file is found and $CRASH_LOOP_ENV_VAR is set by default to NOMAD_ALLOC_ID which leads to crash loop files: $PWD/crash_loop_$ENV['NOMAD_ALLOC_ID']' (defaults to False)

Exits the application with specified exit_code.

Allocate memory_mb_to_allocate until reaching memory limit and possibly being killed by OOM killer.

Parameters

memory_mb_to_allocate - how much memory application will allocate in total (defaults to 0)
steps - split allocating memory to N steps (defaults to 1)
sleep_between_steps - sleep for N seconds between steps (defaults to 0)

Generate generate_bytes_per_second logs to a given output_fd_param.

Parameters

bytes_per_second - how much logs we should generate per second (defaults to 1024)
seconds - generate logs for N seconds (defaults to 1)
output_fd_param - file to which generate logs (filename or stdout/stderr, defaults to stdout)

Stop TCP listener but keep the main process runnning.
