MosswartOverlord/go-services/docker-compose.go.yml

# Compose OVERRIDE that adds the Go services alongside the live Python stack.
# It only ADDS containers; it never modifies the tracked docker-compose.yml or
# any running Python service.
#
# Invoke from the repo root so the Compose project name resolves to
# "mosswartoverlord" (same as the live stack) and the new container joins the
# existing default network — letting it reach the `db` service by name:
#
#   cd /home/erik/MosswartOverlord
#   export BUILD_VERSION="$(date -u +%Y.%-m.%-d.%H%M)-$(git rev-parse --short HEAD)"
#   docker compose -f docker-compose.yml -f go-services/docker-compose.go.yml \
#       build dereth-tracker-go
#   docker compose -f docker-compose.yml -f go-services/docker-compose.go.yml \
#       up -d --no-deps dereth-tracker-go
#
# --no-deps keeps Compose from touching the already-running `db` (and anything
# else). The service is loopback-bound (127.0.0.1:8770); external reach is only
# ever via the host nginx `location /go/` block (added separately).
