Helm 3 umbrella charts & standalone chart image tags — alternative approach

Helm umbrella charts, for those who aren't familiar, describe and encapsulate a deployable collection of loosely couple Kubernetes components as a higher-order Helm chart. A collection of software elements that each have their own individual charts but, for whatever reason (e.g. design choices, ease of deployability, versioning complexities), must be installed or upgraded as a since atomic unit.

Tutorial: Deploying TensorFlow models at the edge with NVIDIA Jetson Nano and K3s
Posted on September 5, 2020, Level intermediate Resource Length long
Janakiram MSV put together this tutorial about TensorFlow models. We will explore the idea of running TensorFlow models as microservices at the edge. Jetson Nano, a powerful edge computing device will run the K3s distribution from Rancher Labs. It can be a single node K3s cluster or join an existing K3s cluster just as an agent.
