How can I enable logging in a Python application running in Docker?

You can enable logging in a Python application running in Docker by configuring the logging module in your Python code and ensuring that your Docker container's stdout and stderr are properly set up.

What specific configurations do I need to set in my Python code?

You should import the logging module, set the logging level, and configure a handler to output logs to stdout. Here's a simple example:

import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)
logger.info('This is an info message')

How do I view the logs from my Docker container?

You can view the logs from your Docker container using the command docker logs <container_id>. This will show you the output from stdout and stderr.

Is there a way to log to a file instead of stdout?

Yes, you can configure a file handler in your logging setup. Just specify a file path in the FileHandler constructor.
