I have been bit late to Kubernetes world, but ever since I have started using it, I have been part of a great teams building awesome applications and using Helm package manager. With Helm, you package your Kubernetes application as charts, which are then stored in Helm chart repo. Helm also has a templating engine allowing you to set values in your charts dynamically allowing you to manage your applications more easily. Azure Container Registry (ACR) currently supports publishing Helm 3 charts to ACR and it is currently in preview.

I have previously blogged about publishing VSCode extensions to VSMarketplace (using GitHub actions). However, that workflow relied heavily on the branching strategy and was on assumption that anything that is merged to master is ready for publishing to VSMarketplace.
