Nice to see this Forum, I have a problem when I run the docker command for Fluentd.
user@ubuntu:~$ docker run -p 24220:24220 -p 24224:24224 -v $HOME/fluent:/fluentd/etc -e FLUENTD_CONF=docker.conf fluent/fluentd:stable
Unable to find image 'fluent/fluentd:stable' locally

the last image keeps waiting... and unable to proceed with the lab.

Hello Sudeep, can you try to redo the pull?

user@ubuntu:~$ docker image rm 9406ff63f205

The command should pull the image directly the Fluent public repo on Dockerhub: https://hub.docker.com/r/fluent/fluentd

I've performed a pull on my own local VM and have been able to successfully do so.

If the stable tag is not functional, you may also try to use latestor one of the other v1.x images for that lab.

Thanks Christian, Actually it worked next time I tried today in my office LAN (earlier I was trying in my home LAN).
I didnt need to remove the fluentd image and it just worked on its own this time.
But thanks for the tip.

in lab 1A, page 8, when i install fluentd with the command sudo gem install fluentd I get the following error:
ERROR: Error installing fluentd: fluentd requires Ruby version >= 2.4 and indeed ruby --version shows ruby 2.3.1p112 (2016-04-26)

I am using ubuntu16.04.6, maybe I should switch to ubuntu18.04 instead ?

Works fine with Ubuntu 18.

The vanilla apt repositories on Ubuntu 16.04 do not serve any Ruby versions beyond 2.3, unfortunately. We'll be updating the course material to allow the latest versions of Ruby and Fluentd to install and run successfully on Ubuntu 16.04.
