 Set `project_id` on the active profile to omit `--project` (stored in
 `~/.containr.yaml` under `profiles.<name>.project_id`).
 
+## Service volumes

+`services update` manages mounts; flags replace the whole mount list:
+
+```bash
+containr services update <id> --volume data:/data --bind /srv/cfg:/etc/app:ro
+containr services update <id> --clear-volumes

+
+`type` is `volume` (docker named volume, auto-created) or `bind` (host
+path). `target` must be absolute. Mounts apply on the next deploy or
+redeploy — `containr deploy <id>` to apply immediately.
+
+`volumes list` shows the node's docker volume inventory with in-use
+flags; `volumes delete <name>` removes an unused volume (admin scope).

 - **Idempotency**: send `Idempotency-Key: <uuid>` on POSTs — the first response replays for 24h; concurrent duplicates get 409. Always safe to send.
 - **Pagination**: `?limit=` + `?cursor=` (pass `pagination.next_cursor` verbatim; legacy `?page=` also works). Invalid cursors fall back to page 1.
 - **Deployments**: serialized per service — a deploy on a busy service returns `status: queued` and runs when the active one finishes. `POST /deployments/{id}/cancel` drops queued (`200 cancelled`) or aborts running (`202 cancelling`) work. `no_cache: true` on create disables the Docker layer cache. `PUT /services/{id}/variables` accepts `redeploy: true` to apply env changes to running containers.
+- **Volumes**: service mounts via `PUT /services/{id}` `volumes: [{type: volume|bind, source, target, read_only}]` — replaces the whole list (`[]` clears), applied on next deploy. `GET /admin/volumes` inventories node volumes with `in_use` flags; `DELETE /admin/volumes/{name}` removes unused ones (admin).
 - **Identifiers**: all ids are UUIDs. Tokens: `cnp_` user PATs, `cagt_` agent onboarding tokens.
