# A local Kubernetes emulator (k3s) as a stack-scoped Atmos component.
# `atmos emulator up kubernetes -s dev` starts (or reuses) the privileged k3s
# container; the `local-k3s` identity in atmos.yaml harvests its kubeconfig and
# injects KUBECONFIG for the Kubernetes (Kustomize) component. k3s runs privileged
# (a driver default); under a rootless runtime the manager swaps in the
# cgroup-nesting entrypoint automatically.

      # Run as a throwaway cluster (no persisted state across down/up). This keeps
      # the demo cross-platform: k3s's embedded datastore creates a unix socket in
      # its data dir, and persisting that dir via a host bind-mount fails on macOS
      # (Docker/Podman virtiofs rejects `chmod` on the socket). A fresh cluster on
      # each `up` is exactly what a demo wants anyway.
