Tiltfile

# -*- mode: Python -*-
#
# Tiltfile for local KubeLB development.
#
# Watches source files and rebuilds+redeploys the manager and CCM into their
# respective kind clusters. Processes run INSIDE the clusters (so
# envoycp.kubelb.svc xDS keeps working). Under the hood just calls
# `make dev-reload`, which uses hash-tracked builds to skip unchanged
# components.
#
# Usage (via Makefile): `make dev-tilt`
#
# Prerequisites: `make dev-setup` must have been run first.

# CCM lives in kind-tenant1 and is managed via local_resource below

# Reload: rebuilds kubelb + ccm binaries, does hash-skipped docker build +
# kind load + rollout restart across kubelb and tenant1 clusters. Single
# resource so builds stay serialized and there are no concurrent-make races.
# reload.sh internally decides which components actually changed and skips
# untouched ones.
