Instructions on cloning and setting up Kubetail on Ubuntu 16.04.
First, clone the repository from Github to a location on your machine (I keep all of my scripts in the /scripts/ directory so I will clone this here).
cd /scripts/ git clone https://github.com/johanhaleby/kubetail.git kubetail
Next, make a symbolic link from the directory to your /usr/bin directory so it can be called simply by running the command kubetail directly.
sudo ln -s /scripts/kubetail/kubetail /usr/bin/
You should now be able to execute kubetail directly.
