+## Logging drivers (--log-driver)
+
+You can specify a different logging driver for the container than for the daemon.
+
+### Logging driver: none
+
+Disables any logging for the container. `docker logs` won't be available with
+this driver.
+
+### Log driver: json-file
+
+Default logging driver for Docker. Writes JSON messages to file. `docker logs`
+command is available only for this logging driver
