Containerizes the momentum monolith and packages every run mode for
deployment in a single Kubernetes namespace, with PostgreSQL hosted in
the cluster.
- Dockerfile (python:3.11-slim, non-root, writable /app/data) + .dockerignore
- GitHub Actions workflow publishing to ghcr.io/fez5587/momentum-system
- Helm chart (deploy/helm/momentum):
* PostgreSQL StatefulSet + PVC (single source of truth; schema
auto-creates from storage/pg_schema.sql on first connect)
* App Deployment running run_live_paper.py with the embedded dashboard
(replicas: 1, Recreate; the dashboard's write endpoints need the
in-process TradingExecutionService) + Service/Ingress on 8010, plus a
wait-for-postgres initContainer
* CronJobs for journal / eod-replay / nightly-tune (US/Eastern via
spec.timeZone) sharing the app data PVC
* ConfigMap (tuning env) + Secret (DATABASE_URL/broker keys, existingSecret
supported); DATABASE_URL built from the in-cluster Postgres service
* Optional Grafana provisioned against the in-cluster Postgres
- deploy/README.md with install, secrets, and constraints
