## Problema
|
|
|
|
Durante auditoria 2026-05-24 (sesion Claude), `docker inspect element_matrix_chat-livekit-jwt-1` volco `LIVEKIT_SECRET=b00e98f70722bc...` cleartext en stdout de la sesion. Aunque la sesion es del operador, el secret quedo en log de conversacion + potencialmente en backups del log + transcripts. Rotacion necesaria por higiene.
|
|
|
|
## Objetivo
|
|
|
|
Nuevo secret 32 bytes hex, mismo `api_key` (o regenerar ambos), stack restart sin perdida sesion.
|
|
|
|
## Plan
|
|
|
|
1. Generar nuevo secret: `openssl rand -hex 32`.
|
|
2. Editar `configs/livekit/livekit.yaml` → bloque `keys:` con nuevo valor.
|
|
3. Editar `.env` de docker-compose (var `LIVEKIT_SECRET` consumida por `livekit-jwt`).
|
|
4. Restart `element_matrix_chat-livekit-1` y `element_matrix_chat-livekit-jwt-1` en orden.
|
|
5. Test call Element Call → handshake JWT OK.
|
|
6. Guardar secret antiguo + nuevo en `pass` con timestamp rotacion.
|
|
|
|
## Acceptance
|
|
|
|
- [ ] `docker inspect ... --format "{{.Config.Env}}"` muestra secret nuevo.
|
|
- [ ] Element Call inicia call sin error "invalid token".
|
|
- [ ] Entry `pass matrix/livekit-secret` actualizada.
|
|
|
|
## Definition of Done
|
|
|
|
- [ ] Repetibilidad: rotacion documentada como funcion del registry (candidato `livekit_secret_rotate_bash_infra`).
|
|
- [ ] Observabilidad: rotation log con timestamp.
|
|
|
|
## Notas
|
|
|
|
Considerar promover el procedimiento a funcion del registry: `livekit_secret_rotate_bash_infra(ssh_host, compose_dir)` que automatiza pasos 1-5 y guarda en pass via `gpg_pass_write`.
|
|
|
|
Patron similar para otros secrets del stack (Synapse macaroon, MAS encryption key, postgres passwords) → capability group nuevo `secret-rotation`.
