# Build + push the sitomat control-plane images to a PRIVATE REGISTRY.

# Run from anywhere in the repo, on a host WITH the source. The DEPLOY host does
# not need this script (nor the source) — it only pulls.
#
# Requires a prior `docker login <registry>`.
#
# Env (usually from docker/.env — loaded automatically when present):
#   SITOMAT_IMAGE_REGISTRY          e.g. registry.contoh.go.id/sitomat
#   SITOMAT_IMAGE_TAG               e.g. 1.0.0  (or demo / prod / latest)
#   NEXT_PUBLIC_DEMO_LOGIN          true|false   — BAKED into the web image
#   NEXT_PUBLIC_KEYCLOAK_ENABLED    true|false   — BAKED into the web image
#   WEB_API_BASE_URL                empty = same-origin (recommended); set an
#                                   absolute origin only for two-domain setups
#
# Examples:
#   SITOMAT_IMAGE_REGISTRY=registry.contoh.go.id/sitomat SITOMAT_IMAGE_TAG=1.0.0 \
#     NEXT_PUBLIC_DEMO_LOGIN=false docker/build-push.sh
#
#   # a DEMO image (demo login ON) — separate tag, because the flag is baked:
#   SITOMAT_IMAGE_REGISTRY=registry.contoh.go.id/sitomat SITOMAT_IMAGE_TAG=demo \
#     NEXT_PUBLIC_DEMO_LOGIN=true docker/build-push.sh
