# Thin control Makefile — one target per ctrl/ script, and the subcommand is an
# argument rather than a second target: `make cluster down`, not `make cluster-down`.
#
# The logic lives in the scripts, never here. Each target maps to exactly one
# bash file, and that file holds the variants:
#
#   make cluster up      ->  ctrl/cluster.sh up
#
# Config layers, weakest first: ctrl/versions.env (pinned toolchain) <
# ctrl/env.d/<profile>.env (cluster shape) < ctrl/.env (local, gitignored) <
# the environment. So `make cluster up PROFILE=client` beats everything.
#
# Start with:  make setup    (then: make cluster up && make docs)

# Identity follows the FOLDER NAME, so this directory can be copied elsewhere,
# renamed, and run as a separate environment with no edits. ctrl/.env overrides
# it when you want a name that differs from the directory.
#
# Asked once, of ctrl/ports.sh, which resolves it through lib/config.sh:
#
#   CLUSTER KUBECONTEXT HTTP HTTPS TILT REGISTRY MANIFESTS_DIR
#
# Read positionally, so the order is a contract — ctrl/selftest.sh pins it.
#
# This used to be sed over ctrl/.env plus a slug computed here, which is a
# SECOND derivation of values lib/config.sh already owns — and the two could
# disagree about the port after `make ports persist`, or about the name for any
# directory whose sanitised form differs from its raw one. One source now; the
# Tiltfile reads the same line.

# the build and then printed "make: 'ctrl' is up to date". The empty rule above

# ── the shape every other project uses ─────────────────────────────────────
# Aliases, not a second implementation: each one calls the same script the
# canonical target does.
#
# The header above argues for `make cluster down` over `make cluster-down`, and
# that still holds *within* this file. But rig is one repo among several on the
# same machine, and every other one answers to kind-up / tilt-up. Muscle memory
# spanning six projects beats internal tidiness in one, so both spellings work.
#
# `cluster list` and `cluster free` have no hyphenated twin on purpose — they
# are rig's own, with nothing to be consistent with.
#
# Nothing outside this file reads these names: the script is `ctrl/cluster.sh`
# and it takes the verb. So rename them, delete the ones you never type, or add
# the spelling your own projects use — an alias is two lines, and adding one
# costs nothing but a line in .PHONY above.

kind-up:                       ## alias for `cluster up`
	bash ctrl/cluster.sh up

kind-down:                     ## alias for `cluster down`
	bash ctrl/cluster.sh down

kind-reset:                    ## alias for `cluster reset`
	bash ctrl/cluster.sh reset

# These two match the other projects' spelling. rig ships ctrl/Tiltfile, so they
# run — it deploys the examples in k8s/base until you replace them.
