## Configuration overview

One-Shot Optimizer can be configured to match your deployment and signature requirements. This section covers the main configuration areas.

## Configuration topics

- **[Ports](/products/namirialpkiaas/one-shot/enterprise-documentation/administrator-guides/configuration/ports)** — Default ports and how to change the host port mapping in `docker-compose.yml`.
- **[Logs](/products/namirialpkiaas/one-shot/enterprise-documentation/administrator-guides/configuration/logs)** — Access service logs with `docker-compose logs` for troubleshooting and monitoring.
- **[Rootstore](/products/namirialpkiaas/one-shot/enterprise-documentation/administrator-guides/configuration/rootstore)** — Required for LTV/LTVLITE signature levels. Add trust chain certificates (PEM) so the Optimizer can validate and produce long-term validation signatures. If you do not use LTV/LTVLITE, rootstore configuration is not necessary.
- **[Service settings](/products/namirialpkiaas/one-shot/enterprise-documentation/administrator-guides/configuration/service-settings)** — Billing credentials, certificate and key files for Uanataca connection, and `settings.toml` (environment, TSA URL, default billing). Required for both sandbox and production.
- **[Webhook configuration](/products/namirialpkiaas/one-shot/enterprise-documentation/developer-documentation/callbacks/webhooks)** — Callback URL for request status changes (async flow, VideoID). The production webhook URL must be set in your RA by the Operations Department.


## Default configuration

Default ports and mappings are defined in the `docker-compose.yml` included with the One-Shot distribution. See [Ports](/products/namirialpkiaas/one-shot/enterprise-documentation/administrator-guides/configuration/ports) for the full list and how to customize them.
