Parameters

None of the parameters are required.

File name

If specified, the logging output will be appended to this file. Keep in mind that this file is from the perspective of the Docker container: it should usually be located in a shared filesystem, or in a Docker volume.

If this parameter is not specified, and the Logger name is not specified, the logging output goes to standard out.

Use timestamp

If specified, and the File name parameter is also specified, the file name will be given a timestamp representing when the logging started. 

Logger name

If specified, and the File name parameter is not specified, then this logger will be used for output. The specified name can be that of a pre-existing logger, or a new logger.

Available variables:

• $message: the message to be logged
