How to get Docker Container Logs into Log Analytics Workspace

Question

Configuartion:
Azure VM Standard D2s v3
Linux Ubuntu Server 18.04 LTS
Docker version 19.03.13, build 4484c46d9d

I am trying to get docker container logs into Log Analytics Workspace. Specifically the stdout and stderr i.e. console logs.

I am successfully running omsagent and have changed the configuration in docker to use fluentd based on the documentation I find below:

https://github.com/Microsoft/OMS-docker/blob/master/OlderVersionREADME.md#setting-up

I am able to see heartbeat and perf information for the host, but nothing about docker or the containers.

Am I thinking of this wrong or is this not the right service to use?
