For instance, given that TLS is enabled and you need to add trust for MinIO's own CA and for the CA of a Keycloak server, a Kubernetes secret can be created from the certificate files using `kubectl`:

```
kubectl -n minio create secret generic minio-trusted-certs --from-file=public.crt --from-file=keycloak.crt
```

If TLS is not enabled, you would need only the third party CA:

```

- Familiarity with [MinIO deployment process on Kubernetes](https://min.io/docs/minio/kubernetes/upstream/operations/installation.html).

- Kubernetes cluster with `kubectl` configured.

- Acquire TLS certificates, either from a CA or [create self-signed certificates](https://min.io/docs/minio/kubernetes/upstream/operations/network-encryption.html).

* Inside the `certs` directory, the private key must by named `private.key` and the public key must be named `public.crt`.
* A certificate signed by a CA contains information about the issued identity (e.g. name, expiry, public key) and any intermediate certificates. The root CA is not included.
