Minimal reproduce step

1. package a python function in zip:

❯ tree func
func
├── requirements.txt
└── src
    └── exclamation.py

❯ cat func/requirements.txt
requests==2.28.2

❯ cat func/src/exclamation.py
import requests # just check dependencies is installed

def process(input):
  return str(input) + '!'

❯ zip -r func.zip func
updating: func/ (stored 0%)
updating: func/requirements.txt (stored 0%)
updating: func/src/ (stored 0%)
updating: func/src/exclamation.py (deflated 16%)

2. create some required dir and file:

mkdir -p /pulsar/conf/python-log/ logs/functions && echo "[loggers]
      keys=root

      [handlers]
      keys=stream_handler

      [formatters]
      keys=formatter

      [logger_root]
      level=INFO
      handlers=stream_handler

      [handler_stream_handler]
      class=StreamHandler
      level=INFO
      formatter=formatter
      args=(sys.stdout,)

      [formatter_formatter]
      format=[%(asctime)s] [%(levelname)s] %(filename)s: %(message)s
      datefmt=%Y-%m-%d %H:%M:%S %z" > /pulsar/conf/python-log/python_instance_logging.ini

3. run python instance directly

python /pulsar/instances/python-instance/python_instance_main.py --py /pulsar/download/pulsar_functions/func.zip --logging_directory logs/functions --logging_file exclamation-py-9e1f170e-0 --logging_config_file /pulsar/conf/python-log/python_instance_logging.ini --install_usercode_dependencies true --instance_id 0 --function_id 0-74a988f8-6711-4a9c-9030-a07a54eb2fc4 --function_version 0 --function_details '{"tenant":"public","namespace":"default","name":"exclamation-py-9e1f170e","className":"exclamation","userConfig":"{}","runtime":"PYTHON","autoAck":true,"parallelism":1,"source":{"typeClassName":"[B","inputSpecs":{"persistent://public/default/test-py-input":{}},"cleanupSubscription":true},"sink":{"typeClassName":"[B","topic":"persistent://public/default/test-py-output","producerSpec":{},"forwardSourceMessageProperty":true},"resources":{"cpu":1,"ram":"1073741824"},"componentType":"FUNCTION"}' --pulsar_serviceurl pulsar://localhost:6650 --max_buffered_tuples 100 --port 39093 --metrics_port 39094 --expected_healthcheck_interval -1 --cluster_name sn-platform-pulsar --use_tls false
