Hello,

Version tested 1.17.0 in docker

Running the application

python3 launcher.py -l /tmp/logs

output error

Traceback (most recent call last):
  File "/usr/lib64/python3.6/logging/config.py", line 565, in configure
    handler = self.configure_handler(handlers[name])
  File "/usr/lib64/python3.6/logging/config.py", line 738, in configure_handler
    result = factory(**kwargs)

    return open(self.baseFilename, self.mode, encoding=self.encoding)
FileNotFoundError: [Errno 2] No such file or directory: '/app/logs/server.log'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "launcher.py", line 11, in <module>

    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'file': [Errno 2] No such file or directory: '/app/logs/server.log'

I guess there is a missing configuration in the src/main.py to setup server.log file in the directory taken from the arg.

Hi @dutangp, yes, you are right. -l flag affects only script logs (not server.log), this is a bug

hey,

Just a suggestion, in docker at least, to be able to remove this server.log in file as all the log a shipped to stdout of the container and can be handled differently.

hello,

For info I found the way in docker by rebuilding the Dockerfile with ENTRYPOINT instead of CMD

ENTRYPOINT [ "python3", "launcher.py" ]

and modifying the file logging.json as below

{
  "version": 1,
  "disable_existing_loggers": false,
  "formatters": {
    "simple": {
      "format": "%(asctime)s [%(name)s.%(levelname)s] %(message)s"
    }
  },
  "handlers": {
    "console": {
      "class": "logging.StreamHandler",
      "level": "DEBUG",
      "formatter": "simple",
      "stream": "ext://sys.stdout"
    }
  },
  "loggers": {
  },
  "root": {
    "level": "DEBUG",
    "handlers": [
      "console"
    ]
  }
}

In docker server.log doesn't bring anything as logs can be handled via std out only and redirection to ES. As well the entrypoint can handle the parameters -d, -l, -t.

@bugy no rush at all on fixing this point imho but you are the boss :)

Hi @dutangp, I would agree with you, that a standard logging mechanism in docker is stdout. However, someone can also mount script server log folder to a host folder, making them "persistent". It's needed for script execution logs anyway. For me, the proper fix would be to make it configurable via conf.json. For now I would keep existing behaviour as it is.

@dmarteau @dutangp i made a fix for it, could you test it please?
