docker run --log-driver=syslog --log-opt syslog-address=tcp://<logstash-system-ip>:5000 hello-world
- Check method configured in a running container:
docker inspect -f '{{.HostConfig.LogConfig.Type}}' CONTAINER_ID
docker inspect -f '{{.HostConfig.LogConfig}}' CONTAINER_ID
docker inspect <container_id|container_name> | grep -A 5 LogConfig
"LogConfig": {
"Type": "syslog"
"Config": {}
