Distributions or administrators of Kubernetes may want to control that new Service CIDRs added to the cluster does not overlap with other networks on the cluster, that only belong to a specific range of IPs or just simple retain the existing behavior of only having one ServiceCIDR per cluster.  An example of a Validation Admission Policy to achieve this is:

## Sobre Pydantic

Pydantic incluye los tests para **FastAPI** con sus propios tests, así que nuevas versiones de Pydantic (por encima de `1.0.0`) siempre son compatibles con FastAPI.

Puedes fijar Pydantic a cualquier versión por encima de `1.0.0` que funcione para ti.

Por ejemplo:

```txt
pydantic>=2.7.0,<3.0.0

    private development environments that only carry test data. Prefer this over creating an
    all-trusting `TrustManager` because only hosts on the allowlist are insecure. From
    [our DevServer sample][dev_server]:

    ```kotlin
    val clientCertificates = HandshakeCertificates.Builder()
        .addPlatformTrustedCertificates()
        .addInsecureHost("localhost")
        .build()

    }
  }
