# Container Registry: registry.leeworks.dev

**Decision Date:** 2026-05-24  
**Status:** Planned (Phase 0 prerequisite)

## Decision: Use Gitea's Built-in Container Registry

We will use **Gitea's built-in container registry** (OCI-compatible, enabled via `GITEA_CONTAINER_REGISTRY`) rather than deploying a separate `distribution/distribution` instance.

### Rationale

1. **No new infra** — Gitea is already deployed; enabling the container registry is a config flag, not a new deployment.
2. **Integrated auth** — API keys, org-scoped tokens, and CI secrets work natively with the Gitea registry.
3. **Simpler CI** — Gitea Actions workflows can use `${{ secrets.GITEA_TOKEN }}` to push to `gitea.leeworks.dev/leeworks-agents/<image>`.
4. **OCI compliance** — Gitea's container registry is OCI v1 compliant, compatible with Docker, Podman, and Kubernetes image pulls.

## Registry Hostname

```
registry.leeworks.dev
```

This will be a reverse proxy/ingress alias for `gitea.leeworks.dev` (Gitea's container registry endpoint).

Alternatively, Docker clients can use the Gitea hostname directly:
```
gitea.leeworks.dev/leeworks-agents/<image>:<tag>
```

If a separate hostname is preferred by the operator, configure an Nginx ingress to proxy `registry.leeworks.dev` → Gitea's container registry port.

## Image Naming Convention

```
registry.leeworks.dev/leeworks-agents/<repo-name>:<tag>
```

| API | Image |
|-----|-------|
| ZIP Enrichment | `registry.leeworks.dev/leeworks-agents/zip-enrichment:latest` |
| Holidays | `registry.leeworks.dev/leeworks-agents/holidays:latest` |
| Air Quality | `registry.leeworks.dev/leeworks-agents/air-quality:latest` |
| Docs Site | `registry.leeworks.dev/leeworks-agents/docs-site:latest` |

Tags should also include the git SHA for traceability: `:<sha>` in addition to `:latest`.

---

## Authentication

### Pushing from CI (Gitea Actions)

```yaml
- name: Log in to registry
  run: |
    echo "${{ secrets.GITEA_TOKEN }}" | docker login registry.leeworks.dev \
      -u ${{ gitea.actor }} --password-stdin

- name: Build and push
  run: |
    docker build -t registry.leeworks.dev/leeworks-agents/${{ gitea.repository_name }}:${{ gitea.sha }} .
    docker push registry.leeworks.dev/leeworks-agents/${{ gitea.repository_name }}:${{ gitea.sha }}
    docker tag registry.leeworks.dev/leeworks-agents/${{ gitea.repository_name }}:${{ gitea.sha }} \
               registry.leeworks.dev/leeworks-agents/${{ gitea.repository_name }}:latest
    docker push registry.leeworks.dev/leeworks-agents/${{ gitea.repository_name }}:latest
```

### Pulling from Kubernetes

Create an image pull secret in each namespace:

```bash
kubectl create secret docker-registry gitea-registry \
  --docker-server=registry.leeworks.dev \
  --docker-username=<gitea-user> \
  --docker-password=<gitea-token> \
  --docker-email=ci@leeworks.dev \
  -n <namespace>
```

Reference in pod spec:
```yaml
spec:
  imagePullSecrets:
    - name: gitea-registry
```

## Enabling Gitea Container Registry

If not already enabled, the Gitea administrator needs to ensure:

1. In `app.ini` (or Helm values), container registry is enabled:
   ```ini
   [packages]
   ENABLED = true
   ```
2. The Gitea service is accessible on port 443 at `gitea.leeworks.dev`.
3. If using `registry.leeworks.dev` as an alias, configure an Nginx Ingress:
   ```yaml
   apiVersion: networking.k8s.io/v1
   kind: Ingress
   metadata:
     name: registry-ingress
     namespace: gitea
     annotations:
       cert-manager.io/cluster-issuer: letsencrypt-prod
       nginx.ingress.kubernetes.io/proxy-body-size: "0"
       nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
       nginx.ingress.kubernetes.io/proxy-send-timeout: "600"
   spec:
     ingressClassName: nginx
     tls:
       - hosts:
           - registry.leeworks.dev
         secretName: registry-tls
     rules:
       - host: registry.leeworks.dev
         http:
           paths:
             - path: /
               pathType: Prefix
               backend:
                 service:
                   name: gitea-http
                   port:
                     number: 3000
   ```

---

## Verification

```bash
# Test login
docker login registry.leeworks.dev -u <user> -p <token>

# Test push
docker pull alpine:latest
docker tag alpine:latest registry.leeworks.dev/leeworks-agents/test:latest
docker push registry.leeworks.dev/leeworks-agents/test:latest

# Test pull from cluster
kubectl run test-pull --image=registry.leeworks.dev/leeworks-agents/test:latest \
  --image-pull-policy=Always --rm -it --restart=Never -- echo "Registry works"
```

## Phase 4 Reference

All API repos should update their `ROADMAP.md §Phase 4` to reference:
```
registry.leeworks.dev/leeworks-agents/<repo>:<tag>
```
as the image target for CI pushes and Flux HelmRelease image references.
