How to get logs from Docker with journald driver?

Question

OpenSuse Tumbleweed + Docker 17.04. I created /etc/docker/daemon.json with:

{
    "log-driver": "journald",
    "log-opts": {
            "labels": "my_test",
            "env": "os,customer"
    }
}

Then I started docker daemon: systemctl start docker. Checked it: sudo docker info|grep Logg and see journald as current default driver. Also sudo docker inspect -f '{{.HostConfig.LogConfig.Type}}' MY-CONTAINER-ID shows me journald again. Docker was run as

sudo docker run -ti -v /sys/fs/cgroup:/sys/fs/cgroup --tmpfs /run/dbus --tmpfs /run/lock --cap-add=ALL MY-CONTAINER

and then I SH-ed to it. In Docker I made several log-messages with:

logger XXX
logger -p local0.notice XXX
# etc...

I'm see these messages in Docker journald with journalctl -n .... And I supposed that I'll find those log-messages in the container ("host OS") too: with journalctl -n ... - nothing. With docker logs MY-CONTAINER-ID - nothing too. I want to log messages from Docker to container ("host") journald. Configuration looks right, but log messages are missing. Would somebody help me - what is wrong with Docker on OpenSuse/with my configuration?

Answer 1

docker journald driver captures the stdout and stderr of the container process.

On the other hand, logger command sends a messase to /dev/log.

Edit

It would be nice to do logger -s
