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 log files.

Can I also set up logging for multiple services?

Yes, you can set up logging for each service individually in the docker-compose.yml file. Just repeat the logging configuration under each service.

What if I want to send logs to a centralized logging service?

You can use logging drivers like fluentd, gelf, or syslog to send logs to a centralized logging service. Just specify the driver and its options in your service configuration.
