Deploying applications to Kubernetes using Helm
summary
Helm packages Kubernetes YAML into versioned charts and the demo builds, packages and publishes a chart to a GitHub chart repo, then installs SQL Server images (shows SQL Server 2022 CU5 and also installs CU4), upgrades with helm upgrade and returns to the previous state with helm rollback, and validates pods, ReplicaSets and service IPs. It uses Helm v3 (no Tiller), helm create/package/repo commands, Artifact Hub discovery, and warns that deleting the old ReplicaSet breaks rollbacks.
