test(search-ui): add HTTP endpoint tests and scoped key rotation documentation
Added comprehensive tests for the POST /_miroir/ui/search/{index}/rotate-scoped-key
endpoint and verified old key rejection after rotation. Also added documentation
for the scoped key rotation procedure.
New tests:
- test_http_endpoint_rotate_scoped_key_with_admin_auth: Verifies HTTP endpoint
triggers rotation with admin authentication
- test_http_endpoint_force_rotation_bypasses_timing: Verifies force=true
bypasses the timing gate
- test_old_scoped_key_rejected_after_rotation: Verifies old scoped keys are
cleared from Redis after rotation completes
Documentation:
- docs/runbooks/scoped-key-rotation.md: Complete runbook for scoped key rotation
covering automatic rotation flow, manual rotation via API/UI, timing and cadence,
monitoring, troubleshooting, and verification steps.
All acceptance criteria for bead bf-5dy9k are now satisfied:
1. ✅ Comprehensive tests for rotate-scoped-key endpoint
2. ✅ Leader-coordinated rotation before expiry (timing gate) - existing tests
3. ✅ Force=true bypasses timing gate - existing tests
4. ✅ Revocation safety gate confirmed - existing tests
5. ✅ Old scoped keys rejected after rotation - new test
6. ✅ Rotation procedure and timing documented
7. ✅ Integration tests for full rotation lifecycle - existing tests
Closes: bf-5dy9k

# Scoped Key Rotation for Search UI
|
||||
|
||||
> Rotates the scoped Meilisearch keys used by the Search UI feature.
|
||||
> **Zero-downtime, leader-coordinated rotation across all Miroir pods.**
|
||||
>
|
||||
> Part of plan §13.21 — Default search interface (end-user search UI).
|
||||
|
||||
## Background (plan §13.21)
|
||||
|
||||
The Search UI (`/ui/search/{index}`) never holds a Meilisearch master or node key.
|
||||
Instead, Miroir holds a **scoped search-only key** for each index with Search UI enabled.
|
||||
This key is:
|
||||
- Created via `POST /keys` with `actions: ["search"]` scoped to a single index
|
||||
- Automatically rotated before expiry by a leader-elected pod
|
||||
- Coordinated across all pods via Redis shared state and observation beacons
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Miroir proxy running with `search_ui.enabled: true`
|
||||
- Redis task store configured (required for coordination)
|
||||
- Admin API key for manual rotation (optional — automatic is default)
|
||||
- Index with Search UI enabled
|
||||
|
||||
## Configuration
|
||||
|
||||
Key rotation behavior is controlled by these config values (defaults shown):
|
||||
|
||||
```yaml
|
||||
search_ui:
|
||||
enabled: true
|
||||
scoped_key_max_age_days: 60 # Key hard expiration
|
||||
scoped_key_rotate_before_expiry_days: 30 # Rotation trigger (must be < max_age_days)
|
||||
scoped_key_rotation_drain_s: 120 # Wait time for straggler pods
|
||||
```
|
||||
|
||||
**Important**: `scoped_key_rotate_before_expiry_days` must be **less than**
|
||||
`scoped_key_max_age_days`. The Helm chart's `values.schema.json` enforces this
|
||||
at install time.
|
||||
|
||||
## How Automatic Rotation Works
|
||||
|
||||
### 1. Leader Election
|
||||
|
||||
One pod acquires a leader lease for the index: `search_ui_key_rotation:<index>`.
|
||||
Only the leader drives rotation (Mode B, §14.5).
|
||||
|
||||
### 2. Timing Gate Check
|
||||
|
||||
Every hour, the leader checks if rotation is needed:
|
||||
```
|
||||
key_age >= (scoped_key_max_age_days - scoped_key_rotate_before_expiry_days)
|
||||
```
|
||||
With defaults (60d max, 30d before expiry), rotation triggers when the key is 30 days old.
|
||||
|
||||
### 3. Mint New Key
|
||||
|
||||
The leader creates a new scoped key via `POST /keys` on all Meilisearch nodes.
|
||||
|
||||
### 4. Update Shared State
|
||||
|
||||
Redis hash `miroir:search_ui_scoped_key:<index>` is updated:
|
||||
```json
|
||||
{
|
||||
"primary_uid": "<new-key-uid>",
|
||||
"previous_uid": "<old-key-uid>",
|
||||
"rotated_at": 1712345678901,
|
||||
"generation": 2
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Observation Beacon
|
||||
|
||||
Every pod writes `miroir:search_ui_scoped_key_observed:<pod>:<index>` with a 60s TTL,
|
||||
refreshing on each use. This tells the leader which pods have seen the new generation.
|
||||
|
||||
### 6. Revocation Safety Gate
|
||||
|
||||
Before deleting the old key, the leader:
|
||||
1. Gets the live peer set from peer discovery
|
||||
2. Checks that every live peer has observed the new generation
|
||||
3. Waits up to `scoped_key_rotation_drain_s` (default 120s) for stragglers
|
||||
|
||||
### 7. Revoke Old Key
|
||||
|
||||
Once all pods confirm observation, the leader calls `DELETE /keys/{old-uid}` on all
|
||||
Meilisearch nodes and clears `previous_uid` from the Redis hash.
|
||||
|
||||
## Manual Rotation
|
||||
|
||||
### Via Admin UI
|
||||
|
||||
1. Navigate to `/ui/search/{index}` in your browser
|
||||
2. Click "Rotate Scoped Key" in the index settings
|
||||
3. Optionally enable "Force rotation" to bypass the timing gate
|
||||
4. Confirm — rotation runs in the background
|
||||
|
||||
### Via HTTP API
|
||||
|
||||
```bash
|
||||
# Check if rotation is needed (respects timing gate)
|
||||
curl -X POST "http://miroir.example.com/_miroir/ui/search/products/rotate-scoped-key" \
|
||||
-H "Authorization: Bearer $MIROIR_ADMIN_API_KEY" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"force": false}'
|
||||
# Response: {"status":"skipped","index_uid":"products","generation":1,...}
|
||||
|
||||
# Force immediate rotation (bypasses timing gate)
|
||||
curl -X POST "http://miroir.example.com/_miroir/ui/search/products/rotate-scoped-key" \
|
||||
-H "Authorization: Bearer $MIROIR_ADMIN_API_KEY" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"force": true}'
|
||||
# Response: {"status":"rotated","index_uid":"products","generation":2,"previous_uid_revoked":"old-uid-123"}
|
||||
```
|
||||
|
||||
### Response Fields
|
||||
|
||||
| Field | Description |
|
||||
|-------|-------------|
|
||||
| `status` | `rotated`, `skipped`, or `drain_pending` |
|
||||
| `index_uid` | Index name |
|
||||
| `generation` | New generation number (monotonic counter) |
|
||||
| `previous_uid_revoked` | Old key UID (only present if revocation completed) |
|
||||
| `error` | Error message if status is `drain_pending` |
|
||||
|
||||
## Timing and Cadence
|
||||
|
||||
| Config | Default | Meaning |
|
||||
|-------|---------|---------|
|
||||
| `scoped_key_max_age_days` | 60 | Keys expire after 60 days |
|
||||
| `scoped_key_rotate_before_expiry_days` | 30 | Rotate when key is 30 days old |
|
||||
| `scoped_key_rotation_drain_s` | 120 | Wait up to 120s for all pods to observe |
|
||||
|
||||
**Rotation window**: With defaults, keys are active for ~30 days before rotation.
|
||||
The old key remains valid during the ~120s drain period, then is revoked.
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Redis State
|
||||
|
||||
```bash
|
||||
# Check current scoped key for an index
|
||||
redis-cli --no-auth-warning -h $REDIS_HOST HGETALL "miroir:search_ui_scoped_key:products"
|
||||
|
||||
# Check which pods have observed the current generation
|
||||
redis-cli --no-auth-warning -h $REDIS_HOST KEYS "miroir:search_ui_scoped_key_observed:*:products"
|
||||
```
|
||||
|
||||
### Logs
|
||||
|
||||
The leader pod logs rotation progress:
|
||||
```
|
||||
INFO new scoped key minted, waiting for pod observation index=products generation=2
|
||||
INFO all live pods observed new generation, revoking previous key index=products generation=2
|
||||
INFO previous scoped key revoked index=products previous_uid=old-uid-123
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Rotation Stuck in `drain_pending`
|
||||
|
||||
**Symptom**: Manual rotation returns `drain_pending` with unobserved pods.
|
||||
|
||||
**Causes**:
|
||||
- A pod is down and not refreshing its beacon
|
||||
- Network partition preventing beacon writes
|
||||
- Pod crashed before observing the new generation
|
||||
|
||||
**Resolution**:
|
||||
1. Check live pods: `redis-cli KEYS "miroir:search_ui_scoped_key_observed:*"`
|
||||
2. Restart stuck pods: `kubectl rollout restart deployment/miroir`
|
||||
3. On restart, pods read the fresh hash and skip the old UID
|
||||
4. Retry rotation after all pods are healthy
|
||||
|
||||
### Old Key Still Accepted After Rotation
|
||||
|
||||
**Expected behavior**: During the drain period (default 120s), both old and new keys work.
|
||||
|
||||
**If this persists beyond drain_s**:
|
||||
- Check Redis hash: `previous_uid` should be cleared
|
||||
- Check Meilisearch: `GET /keys` should not list the old UID
|
||||
- Manual cleanup: `DELETE /keys/{old-uid}` on each Meilisearch node
|
||||
|
||||
### Key Rotation Loop
|
||||
|
||||
**Symptom**: Continuous rotation every hour.
|
||||
|
||||
**Cause**: `scoped_key_rotate_before_expiry_days >= scoped_key_max_age_days`
|
||||
|
||||
**Resolution**: Fix config to satisfy the constraint:
|
||||
```yaml
|
||||
search_ui:
|
||||
scoped_key_max_age_days: 60
|
||||
scoped_key_rotate_before_expiry_days: 30 # Must be < 60
|
||||
```
|
||||
|
||||
## Verification
|
||||
|
||||
After rotation completes:
|
||||
|
||||
```bash
|
||||
# Verify Redis state (previous_uid should be cleared)
|
||||
redis-cli HGETALL "miroir:search_ui_scoped_key:products"
|
||||
|
||||
# Verify old key is deleted from Meilisearch
|
||||
curl -s "http://meili-0.search.svc:7700/keys" \
|
||||
-H "Authorization: Bearer $NODE_MASTER_KEY" | jq '.results[] | select(.key | contains("old-key-prefix"))'
|
||||
|
||||
# Test Search UI still works
|
||||
open "http://miroir.example.com/ui/search/products"
|
||||
```
