# Deployment notes
Milestone 4 adapters are designed for explicit opt-in.
Default local verification does not contact:
- etcd
- Kubernetes API
- Redis
- OTLP collector
Production applications should provide credentials and endpoints through their own configuration layer. Do not commit real cluster URLs, database passwords, Redis credentials, or collector tokens.
External tests can be run with:
```bash
docker compose -f examples/production-adapters/docker-compose.yml up -d
cargo test --ignored --features external-tests
```
Before publishing a service, use the [production checklist](production-checklist.md). It covers configuration, authentication, reliability, observability, data adapters, registry adapters, verification commands, and rollback boundaries.
