supabase/deploy.sh

Launches the slimmed Supabase control-plane stack (Auth, Realtime, Meta, Studio,
Analytics). Postgres is provided by CloudNativePG (knoe-db-rw). Storage/MinIO/
Imgproxy and the local Supabase Kong are not deployed; the shared Kong in
kube-system is the API gateway and Garage is the object store.

Usage:
  ./deploy.sh [options]

Options:
  --mode <local|k3d|k8s>  Deployment mode ('local' for Docker Compose, 'k3d' for local k3d, 'k8s' for generic k8s/k3s; default: k3d)
  --helm-template-only    Render Helm manifests to supabase/k8s without applying (for pipelines)
  --prefetch-images-only  Discover/prepare/load/import Supabase images only, then exit (k3d mode)
  --skip-prefetch         Skip image prefetch during deploy (for preloaded flows)
  --with-dev-helpers     Include docker/dev/docker-compose.dev.yml
  --foreground           Run docker compose in the foreground (default: detached, local mode only)
  -f, --force            Reset the Supabase namespace before applying manifests (k3d only; default)
  --no-force             Skip namespace reset (k3d only)
  -c, --config <path>    Path to prole.cfg (loads environment defaults)
  -h, --help             Show help

Notes:
  - This script syncs the Supabase repo into $DEV_HOME/supabase.
  - The deployment runs as a single "supabase" namespace via the Compose project name.
  - For k3d mode, manifests are applied from $SUPABASE_K8S_DIR.
  - Docker image artifacts are cached in $DOCKER_IMPORT_DIR.
  - This script preserves the README/DEVELOPERS steps:
      1) use docker/docker-compose.yml
      2) copy docker/.env.example -> docker/.env (if missing)
      3) run docker compose up
