Keeping Docker logs only in memory

There are various log drivers available for Docker but it looks like all of them persist the logs to disk.

To reduce disk usage I would like to keep the logs only in memory (and limited to a certain size).

I could use log driver none but I believe it immediately discards all log messages and sometimes it is still helpful to look at the currently produced logs without having to restart the container to switch to a different log driver.

Is this possible?

One solution could be, I never tried, is to mount a memory filesystem (tmpfs) and let docker log to that directory with syslog

create a memory filesystem:

let docker log with syslog:
