How do I set up logging in Docker Compose?

To set up logging in Docker Compose, you can define logging options in your docker-compose.yml file. What type of logging do you want to configure?

I want to use the JSON file logging driver.

You can specify the logging driver like this:

services:
  your_service:
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"

This configuration limits the log file size and keeps a maximum of 3 files.

Can I also log to a remote server?

Yes, you can use the gelf logging driver to send logs to a remote Graylog server. Just specify the server's address in the options.

What if I want to see logs in real-time?

You can use the docker-compose logs -f command to follow the logs in real-time for your services.
