How does Docker’s logging driver system work and what are the trade-offs between the json-file and the syslog drivers?

Accepted Answer

Docker logging drivers determine where container logs are sent. The json-file driver stores logs locally in JSON format, while the syslog driver forwards logs to a remote server. The trade-off is that json-file allows easy access to logs but can consume disk space, while syslog enables centralized logging but makes docker logs unavailable.
