Overview
Containers executed by Docker behave differently in respect to tag resolution than the same containers executed from a Kubernetes pod.
We create a "color:latest" container that serves "blue" and push it on Docker Hub.
Dockerfile:
FROM busybox CMD echo "I am blue"
docker build -t docker.io/ovidiufeodorov/color:latest . docker push ovidiufeodorov/color
