How does the fluentd log driver work?

[nik736]

Hi there,

When using docker run I can use the following to receive docker logs to the fluentd endpoint.
--log-driver=fluentd --log-opt=fluentd-address=remote_ip:24224

My fluentd server is not on the same machine so I am sending it to a remote ip or hostname. When using the same with nerdctl it is not working, no logs are received and I am not sure how to debug. I am using nerdctl 1.0.0

Looking through the docs I can see the following line: The fluentd daemon must be running on the host machine. But this does not make sense for me, as I am running fluentd on another machine.

How am I able to get this up and running?

Any help is appreciated, thanks!

Hi @nik736 ,

Did you get any output when running with nerdctl --debug run mode ?
Where did you find this line The fluentd daemon must be running on the host machine. ?

Can you please share your fluentd configuration ? as we are using a fluent-client-library to push log entries, I believe that you need the forward protocol plugin configured on the fluentd side
