How can I configure Python logging to output to stdout in a Docker container?

How can I configure Python logging to output to stdout in a Docker container?

You can configure Python logging to output to stdout by setting the logging configuration in your Python script. Use the StreamHandler to direct logs to stdout.

Can you show me a code example for that?

Sure! Here's a simple example:

import logging

# Configure logging
logging.basicConfig(level=logging.INFO)

# Create a logger
logger = logging.getLogger(__name__)

# Log a message
logger.info('This is an info message')

What if I want to log errors as well?

You can log errors by setting the logging level to ERROR or by adding another handler. Here's how:

logging.basicConfig(level=logging.ERROR)

How do I run this in a Docker container?

To run this in a Docker container, ensure your Dockerfile installs Python and copies your script. Then, use CMD to run your script.
