At the beginning of the session we took an overview of the companies and products within the CNCF ecosystem. You can watch it here https://landscape.cncf.io/
Secondly, we looked at https://kustomize.io/, an integrated management tool within Kubernetes.
Finally, we took a walk through a cluster set up in DigitalOcean. Applying different changes with kustomize we could see in real time the repercussions they had on the cluster state.
