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 -

First, create the secret: ```bash kubectl create secret generic my-minio-secret --from-literal=rootUser=foobarbaz --from-literal=rootPassword=foobarbazqux ``` Then install the chart, specifying that you want to use an existing secret: ```bash helm install --set existingSecret=my-minio-secret minio/minio...
