and follow the instructions fn the [init hooks documentation](/aws/capabilities/config/initialization-hooks) for configuring LocalStack to use the hook directory as a `boot` hook.

## Disabling TLS verification for LocalStack Cloud

If your proxy intercepts traffic to LocalStack cloud services (e.g., license server), you can disable TLS verification for these specific requests using the `SSL_NO_VERIFY` [configuration variable](/aws/capabilities/config/configuration#security) (or `LOCALSTACK_SSL_NO_VERIFY` in Docker).

```bash
SSL_NO_VERIFY=1 localstack start
```

:::caution
This approach disables certificate verification rather than trusting your proxy's certificate.
Use custom certificates (as described above) when you need to maintain proper TLS verification for all traffic.
