How to fix empty Docker LogPath

Question

I’m setting up a new Redis server via docker-compose and cannot find json docker log file.

Redis log are /dev/stdout and visible via docker-compose logs command.

Docker version 1.13.1, build 7f2769b/1.13.1

docker-compose version 1.24.1, build 4667896

docker inspect --format='{{.LogPath}}' docker-compose-redis_redis_1 shows nothing

Snippet from docker-compose.yml:

    logging:
    #limit logs to 200MB (4rotations of 50M each)
      driver: "json-file"
      options:
        max-size: "50m"
        max-file: "4"

I expect to find json file in /var/lib/docker/containers/container-id/

Add the following to docker-compose:

logging:
  driver: "json-file"

Im not sure yet to figure out how to change system wide, but I noticed I'm using journald default.

cat /etc/docker/daemon.json.original
{
    "log-driver": "journald",
    "storage-driver": "overlay2"
}
