For testing purposes, here is [how to create self-signed certificates](https://github.com/minio/minio/tree/master/docs/tls#3-generate-self-signed-certificates).

## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.

```

### MinIO Custom Access and Secret Keys using Docker secrets

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as [Docker secrets](https://docs.docker.com/engine/swarm/secrets/). MinIO server also allows regular strings as access and secret keys.

```
echo "AKIAIOSFODNN7EXAMPLE" | docker secret create access_key -

This label will be displayed in the output of a successful install.

### Existing secret

Instead of having this chart create the secret for you, you can supply a preexisting secret, much
like an existing PersistentVolumeClaim.

First, create the secret:

```bash
kubectl create secret generic my-minio-secret --from-literal=rootUser=foobarbaz --from-literal=rootPassword=foobarbazqux
```

	// There is no max length enforcement for access keys
	accessKeyMaxLen = 20

	// Minimum length for MinIO secret key for both server
	secretKeyMinLen = 8

	// Maximum secret key length for MinIO, this
	// is used when autogenerating new credentials.
	// There is no max length enforcement for secret keys
	secretKeyMaxLen = 40

	// Alpha numeric table used for generating access keys.

  ## MINIO_SUBNET_LICENSE: "License key obtained from https://subnet.min.io"
  ## MINIO_BROWSER: "off"

## The name of a secret in the same kubernetes namespace which contain secret values
## This can be useful for LDAP password, etc
## The key in the secret must be 'config.env'
##
extraSecret: ~

## OpenID Identity Management

- name: trusted-cert-secret-volume
  secret:
    secretName: {{ $certSecret }}
    {{- if ne $publicCrt "" }}
    items:
    - key: {{ $publicCrt }}
      path: public.crt
    {{- end }}
{{- end }}
{{- end -}}

{{/*

otherwise it generates a random value.

    return DBUser(name="John", surname="Doe", password_hash="secret")

def response_model_list_of_model_no_annotation():

	if len(cred.SecretKey) != secretKeyMaxLen {
