# Concelier & Excititor Mirror Operations
|
||
|
||
This runbook describes how Stella Ops operates the managed mirrors under `*.stella-ops.org`.
|
||
It covers Docker Compose and Helm deployment overlays, secret handling for multi-tenant
|
||
authn, CDN fronting, and the recurring sync pipeline that keeps mirror bundles current.
|
||
|
||
## 1. Prerequisites
|
||
|
||
- **Authority access** – client credentials (`client_id` + secret) authorised for
|
||
`concelier.mirror.read` and `excititor.mirror.read` scopes. Secrets live outside git.
|
||
- **Signed TLS certificates** – wildcard or per-domain (`mirror-primary`, `mirror-community`).
|
||
Store them under `deploy/compose/mirror-gateway/tls/` or in Kubernetes secrets.
|
||
- **Mirror gateway credentials** – Basic Auth htpasswd files per domain. Generate with
|
||
`htpasswd -B`. Operators distribute credentials to downstream consumers.
|
||
- **Export artifact source** – read access to the canonical S3 buckets (or rsync share)
|
||
that hold `concelier` JSON bundles and `excititor` VEX exports.
|
||
- **Persistent volumes** – storage for Concelier job metadata and mirror export trees.
|
||
For Helm, provision PVCs (`concelier-mirror-jobs`, `concelier-mirror-exports`,
|
||
`excititor-mirror-exports`, `mirror-mongo-data`, `mirror-minio-data`) before rollout.
|
||
|
||
## 2. Secret & certificate layout
|
||
|
||
### Docker Compose (`deploy/compose/docker-compose.mirror.yaml`)
|
||
|
||
- `deploy/compose/env/mirror.env.example` – copy to `.env` and adjust quotas or domain IDs.
|
||
- `deploy/compose/mirror-secrets/` – mount read-only into `/run/secrets`. Place:
|
||
- `concelier-authority-client` – Authority client secret.
|
||
- `excititor-authority-client` (optional) – reserve for future authn.
|
||
- `deploy/compose/mirror-gateway/tls/` – PEM-encoded cert/key pairs:
|
||
- `mirror-primary.crt`, `mirror-primary.key`
|
||
- `mirror-community.crt`, `mirror-community.key`
|
||
- `deploy/compose/mirror-gateway/secrets/` – htpasswd files:
|
||
- `mirror-primary.htpasswd`
|
||
- `mirror-community.htpasswd`
|
||
|
||
### Helm (`deploy/helm/stellaops/values-mirror.yaml`)
|
||
|
||
Create secrets in the target namespace:
|
||
|
||
```bash
|
||
kubectl create secret generic concelier-mirror-auth \
|
||
--from-file=concelier-authority-client=concelier-authority-client
|
||
|
||
kubectl create secret generic excititor-mirror-auth \
|
||
--from-file=excititor-authority-client=excititor-authority-client
|
||
|
||
kubectl create secret tls mirror-gateway-tls \
|
||
--cert=mirror-primary.crt --key=mirror-primary.key
|
||
|
||
kubectl create secret generic mirror-gateway-htpasswd \
|
||
--from-file=mirror-primary.htpasswd --from-file=mirror-community.htpasswd
|
||
```
|
||
|
||
> Keep Basic Auth lists short-lived (rotate quarterly) and document credential recipients.
|
||
|
||
## 3. Deployment
|
||
|
||
### 3.1 Docker Compose (edge mirrors, lab validation)
|
||
|
||
1. `cp deploy/compose/env/mirror.env.example deploy/compose/env/mirror.env`
|
||
2. Populate secrets/tls directories as described above.
|
||
3. Sync mirror bundles (see §4) into `deploy/compose/mirror-data/…` and ensure they are mounted
|
||
on the host path backing the `concelier-exports` and `excititor-exports` volumes.
|
||
4. Run the profile validator: `deploy/tools/validate-profiles.sh`.
|
||
5. Launch: `docker compose --env-file env/mirror.env -f docker-compose.mirror.yaml up -d`.
|
||
|
||
### 3.2 Helm (production mirrors)
|
||
|
||
1. Provision PVCs sized for mirror bundles (baseline: 20 GiB per domain).
|
||
2. Create secrets/tls config maps (§2).
|
||
3. `helm upgrade --install mirror deploy/helm/stellaops -f deploy/helm/stellaops/values-mirror.yaml`.
|
||
4. Annotate the `stellaops-mirror-gateway` service with ingress/LoadBalancer metadata required by
|
||
your CDN (e.g., AWS load balancer scheme internal + NLB idle timeout).
|
||
|
||
## 4. Artifact sync workflow
|
||
|
||
Mirrors never generate exports—they ingest signed bundles produced by the Concelier and Excititor
|
||
export jobs. Recommended sync pattern:
|
||
|
||
### 4.1 Compose host (systemd timer)
|
||
|
||
`/usr/local/bin/mirror-sync.sh`:
|
||
|
||
```bash
|
||
#!/usr/bin/env bash
|
||
set -euo pipefail
|
||
export AWS_ACCESS_KEY_ID=…
|
||
export AWS_SECRET_ACCESS_KEY=…
|
||
|
||
aws s3 sync s3://mirror-stellaops/concelier/latest \
|
||
/opt/stellaops/mirror-data/concelier --delete --size-only
|
||
|
||
aws s3 sync s3://mirror-stellaops/excititor/latest \
|
||
/opt/stellaops/mirror-data/excititor --delete --size-only
|
||
```
|
||
|
||
Schedule with a systemd timer every 5 minutes. The Compose volumes mount `/opt/stellaops/mirror-data/*`
|
||
into the containers read-only, matching `CONCELIER__MIRROR__EXPORTROOT=/exports/json` and
|
||
`EXCITITOR__ARTIFACTS__FILESYSTEM__ROOT=/exports`.
|
||
|
||
### 4.2 Kubernetes (CronJob)
|
||
|
||
Create a CronJob running the AWS CLI (or rclone) in the same namespace, writing into the PVCs:
|
||
|
||
```yaml
|
||
apiVersion: batch/v1
|
||
kind: CronJob
|
||
metadata:
|
||
name: mirror-sync
|
||
spec:
|
||
schedule: "*/5 * * * *"
|
||
jobTemplate:
|
||
spec:
|
||
template:
|
||
spec:
|
||
containers:
|
||
- name: sync
|
||
image: public.ecr.aws/aws-cli/aws-cli@sha256:5df5f52c29f5e3ba46d0ad9e0e3afc98701c4a0f879400b4c5f80d943b5fadea
|
||
command:
|
||
- /bin/sh
|
||
- -c
|
||
- >
|
||
aws s3 sync s3://mirror-stellaops/concelier/latest /exports/concelier --delete --size-only &&
|
||
aws s3 sync s3://mirror-stellaops/excititor/latest /exports/excititor --delete --size-only
|
||
volumeMounts:
|
||
- name: concelier-exports
|
||
mountPath: /exports/concelier
|
||
- name: excititor-exports
|
||
mountPath: /exports/excititor
|
||
envFrom:
|
||
- secretRef:
|
||
name: mirror-sync-aws
|
||
restartPolicy: OnFailure
|
||
volumes:
|
||
- name: concelier-exports
|
||
persistentVolumeClaim:
|
||
claimName: concelier-mirror-exports
|
||
- name: excititor-exports
|
||
persistentVolumeClaim:
|
||
claimName: excititor-mirror-exports
|
||
```
|
||
|
||
## 5. CDN integration
|
||
|
||
1. Point the CDN origin at the mirror gateway (Compose host or Kubernetes LoadBalancer).
|
||
2. Honour the response headers emitted by the gateway and Concelier/Excititor:
|
||
`Cache-Control: public, max-age=300, immutable` for mirror payloads.
|
||
3. Configure origin shields in the CDN to prevent cache stampedes. Recommended TTLs:
|
||
- Index (`/concelier/exports/index.json`, `/excititor/mirror/*/index`) → 60 s.
|
||
- Bundle/manifest payloads → 300 s.
|
||
4. Forward the `Authorization` header—Basic Auth terminates at the gateway.
|
||
5. Enforce per-domain rate limits at the CDN (matching gateway budgets) and enable logging
|
||
to SIEM for anomaly detection.
|
||
|
||
## 6. Smoke tests
|
||
|
||
After each deployment or sync cycle:
|
||
|
||
```bash
|
||
# Index with Basic Auth
|
||
curl -u $PRIMARY_CREDS https://mirror-primary.stella-ops.org/concelier/exports/index.json | jq 'keys'
|
||
|
||
# Mirror manifest signature
|
||
curl -u $PRIMARY_CREDS -I https://mirror-primary.stella-ops.org/concelier/exports/mirror/primary/manifest.json
|
||
|
||
# Excititor consensus bundle metadata
|
||
curl -u $COMMUNITY_CREDS https://mirror-community.stella-ops.org/excititor/mirror/community/index \
|
||
| jq '.exports[].exportKey'
|
||
|
||
# Signed bundle + detached JWS (spot check digests)
|
||
curl -u $PRIMARY_CREDS https://mirror-primary.stella-ops.org/concelier/exports/mirror/primary/bundle.json.jws \
|
||
-o bundle.json.jws
|
||
cosign verify-blob --signature bundle.json.jws --key mirror-key.pub bundle.json
|
||
```
|
||
|
||
Watch the gateway metrics (`nginx_vts` or access logs) for cache hits. In Kubernetes, `kubectl logs deploy/stellaops-mirror-gateway`
|
||
should show `X-Cache-Status: HIT/MISS`.
|
||
|
||
## 7. Maintenance & rotation
|
||
|
||
- **Bundle freshness** – alert if sync job lag exceeds 15 minutes or if `concelier` logs
|
||
`Mirror export root is not configured`.
|
||
- **Secret rotation** – change Authority client secrets and Basic Auth credentials quarterly.
|
||
Update the mounted secrets and restart deployments (`docker compose restart concelier` or
|
||
`kubectl rollout restart deploy/stellaops-concelier`).
|
||
- **TLS renewal** – reissue certificates, place new files, and reload gateway (`docker compose exec mirror-gateway nginx -s reload`).
|
||
- **Quota tuning** – adjust per-domain `MAXDOWNLOADREQUESTSPERHOUR` in `.env` or values file.
|
||
Align CDN rate limits and inform downstreams.
