## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.
We'll use secrets to hold the TLS certificate and key. To create a secret, update the paths to `private.key` and `public.crt`
below.

Then type

```sh
kubectl create secret generic tls-ssl-minio --from-file=path/to/private.key --from-file=path/to/public.crt
```

tls              (on|off)    set to 'on' to enable TLS
tls_skip_verify  (on|off)    trust server TLS without verification, defaults to "on" (verify)
client_tls_cert  (path)      path to client certificate for mTLS auth
client_tls_key   (path)      path to client key for mTLS auth
version          (string)    specify the version of the Kafka cluster
comment          (sentence)  optionally add a comment to this setting
```

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`:

```

## Bundle multiple trusted certificates into one secret and pass that here. Ref: https://github.com/minio/minio/tree/master/docs/tls/kubernetes#2-create-kubernetes-secret
## When using self-signed certificates, remember to include MinIO's own certificate in the bundle with key public.crt.
