These are notes for my Kubernetes/Prometheus workshop. The notes for the Prometheus introduction workshop can be found here.
The first part of this workshop is taken from episode 001 of the excellent TGI Kubernetes series by Heptio.
The demo runs on AWS.
Before the demo, do the following:
To 'clone' a container, you'll have to make an image of that container first, you can do so by "committing" the container. Docker will (by default) pause all processes running in the container during commit to preserve data-consistency.
For example;
docker commit --message="Snapshot of my container" my_container my_container_snapshot:yymmdd
