Application Preview Environments in 5 Minutes
summary
Shows how to use ArgoCD ApplicationSet to auto-create and destroy live preview deployments from GitHub PRs using a single YAML file that generates an namespace per PR. Demo creates a namespace, deploys chart, provisions Ingress and certificates, and serves content; curl returns "Hello World" and a JSON endpoint for PR #25. Environments update to the branch commit, delete when the PR closes, and the demo confirms end-to-end success.
