# Deploy main to briven.tech on kvm4. Runs from the operator's local
# machine — wraps git push + ssh pull + docker compose build/up so the
# rollout becomes one command:
#
#   ./scripts/deploy-kvm4.sh                       # api+web+docs
#   ./scripts/deploy-kvm4.sh api                   # just api
#   ./scripts/deploy-kvm4.sh api web docs runtime  # explicit set
#   ./scripts/deploy-kvm4.sh --no-push api         # local build only
#                                                  # (use when konnos is down)
#
# What it does:
#   1. push current HEAD to konnos (skipped with --no-push)
#   2. ssh into kvm4, git stash any drift, git pull origin main
#   3. docker compose build the requested services with
#      BRIVEN_BUILD_SHA + BRIVEN_BUILD_AT injected as build-args so
#      /info reflects the running commit
#   4. up -d --force-recreate the same services
#   5. wait + curl /info on api so the operator sees the new sha live
#
# Doesn't redeploy database / redis / minio — they survive across
# code changes. Pass them explicitly if you need to.
