# DevOps Requirements

Phase: deployment
Enforcement: informational

## OPS-001: Foxtrot-Compatible Helm Chart

Every deployable service MUST include a Helm chart that honors the Foxtrot deployment contract.

**Rule:** The Helm chart must:
- Use the standard Foxtrot base chart as a dependency (or implement its interface)
- Expose `values.yaml` with the required Foxtrot parameters (replicas, resources, env, configMap references)
- Support the standard lifecycle hooks (pre-deploy validation, health check, rollback trigger)
- Not define its own ingress/networking — Foxtrot manages routing

**Test:** Validate Helm chart structure: check for Foxtrot base chart dependency, required values keys, no ingress resource definitions.

## OPS-002: No Infrastructure Provisioning in Service Repos

Service repositories MUST NOT provision infrastructure (databases, queues, storage, networking). Infrastructure is managed through the dedicated infrastructure repos.

**Rule:** No Terraform, CloudFormation, or Pulumi resource definitions in service repos. Services declare their infrastructure dependencies in a manifest; the platform provisions them.

**Test:** Scan for `*.tf`, `*.template.yaml` (CFN), `Pulumi.*` files in service repos.

## OPS-003: Standard Observability Contract

Every service MUST expose metrics, health, and readiness endpoints in the standard format.

**Rule:**
- `/health` or `/actuator/health` — returns 200 when healthy
- `/ready` or `/actuator/ready` — returns 200 when ready to accept traffic
- Prometheus metrics endpoint at `/metrics` or `/actuator/prometheus`
- Structured JSON logging with correlation ID propagation

**Test:** Check for health/ready endpoint registration in code. Verify logging config outputs JSON format.

## OPS-004: No Pinned Infrastructure Versions

Service Helm charts MUST NOT pin specific infrastructure versions (database versions, queue versions, runtime versions).

**Rule:** Infrastructure version management is handled by the platform team. Services declare compatibility ranges, not exact versions. No `image: postgres:14.2` in service charts.

**Test:** Scan Helm values and templates for hardcoded infrastructure image tags.
