## Pydantic models

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> is a Python library to perform data validation.

You declare the "shape" of the data as classes with attributes.

And each attribute has a type.

```

The server address variable is _required_. TLS is assumed to be on by default. The port in the server address is optional and defaults to 636 if not provided.

**MinIO sends LDAP credentials to the LDAP server for validation. So we _strongly recommend_ to use MinIO with AD/LDAP server over TLS or StartTLS _only_. Using plain-text connection between MinIO and LDAP server means _credentials can be compromised_ by anyone listening to network traffic.**

  istioctl tag set prod --revision 1-8-1 --overwrite

  # Make revision "1-8-1" the default revision, both resulting in that revision handling injection for "istio-injection=enabled"
  # and validating resources cluster-wide
  istioctl tag set default --revision 1-8-1

  # Rollout namespace "test-ns" to update workloads to the "1-8-1" revision
  kubectl rollout restart deployments -n test-ns
