What’s the machine? NAS or PC?

@brizio71 what @Roberto has shown you is what you want to do.

That’s a feature of Docker itself not of the storagenode, you have to use 2 flags

--log-opt max-size=10m 
--log-opt max-file=5

and make sure that you are not setting the following storagenode configuration (via flag or in the configuration file)

log.output string     # can be stdout, stderr, or a filename (default "stderr")

or if you do, set it to stdout or stderr.

if you want to apply the change to all containers then you should add

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "50m",
    "max-file": "1" 
  }
}

into /etc/docker/daemon.json then restart the docker daemon by

systemctl restart docker

I assume you use Linux, somebody may know how to do it on Windows.
