I’m trying to follow Route Docker Logs to ELK Stack and while trying to run:

docker run -d --net=host --log-driver=gelf --log-opt gelf-address=udp://$LOGSTASH_ADDRESS:12201 --log-opt gelf-tag=“fe” nginx

I’m getting following error:

docker: Error response from daemon: unknown log opt “gelf-tag” for gelf log driver.

Please see GELF documentation
You should use just ‘tag’ instead of ‘tag’
docker run -d --net=host --log-driver=gelf --log-opt gelf-address=udp://$LOGSTASH_ADDRESS:12201 --log-opt tag="fe" nginx

I’m guessing you meant to say use tag instead of gelf-tag )
