# NOTE: iot-api uses image 'iot-api:latest' with imagePullPolicy=Never
# The image must be built and loaded onto the scheduled node before deploying.
# Current status: ErrImageNeverPull on kube-node-3 — image not present there.
# To fix: either add nodeSelector to pin to a node with the image, or push the
# image to a registry and change imagePullPolicy to Always.
