First condifuratione and log size

General
1

Hello all,
this is my first post so hope you will be lenient with me :slight_smile:

I’ve just intalled my istance of docker on a RBP4.
I would like to setup a logs size limit and rotation for all my containers in the same way.
Actually I’ve wrote the following /etc/docker/daemon.json as follows:

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "3",
    "labels": "production_status",
    "env": "os,customer"
  }
}

then I’ve restarted the demon but… if I chek

/var/lib/docker/containers# ls -lahR |grep json.log

As you can see, I have files bigger the 10 Mb as espected. What do I wrong?

One more question is, may I set some kind of day-rotation parameter?

Thank you all
