docker logs not fetch dtle log

[kevinbin]

I run a docker image with
docker run --name dtle -p 8190:8190 --network=dtle-net -d actiontech/dtle

when I 'docker ps ' I get a message that this container is running.
f99bd8b279df actiontech/dtle "/usr/bin/dtle serve…" 18 minutes ago Up 18 minutes 0.0.0.0:8190->8190/tcp dtle

I issue the command docker logs dtle, but this command returns nothing.
