Carry Your Legacy Apps Into a GitOps World
summary
Demonstrates using Argo CD and KubeVirt (via OpenShift virtualization and OpenShift GitOps) to bring a legacy VM running Bookinfo into a GitOps workflow, gradually replacing VM-hosted services with container deployments; each replacement is a Git change that auto-syncs and shows deployments popping up, the UI updates (publisher, star colors) as services flip, and a single-line YAML change stops the original VM. Covers stateless use cases and stateful legacy migration with a mixed VM and containerized Bookinfo demo that works end-to-end.
