This Chart provides and example that deploys a standalone MinIO application. It is a single MinIO server running in a pod, as a "deployment", with a small persistent volume claim to persist data (allocated on a block device in this example - could potentially be an NCCS filesystem instead).
This Chart provides an example that deploys a standalone MinIO application. It is a single MinIO server running in a pod, as a "deployment", with a small persistent volume claim to persist data.
This example is a derivative of the [MinIO provided example](https://github.com/minio/minio/blob/master/docs/orchestration/kubernetes/k8s-yaml.md) to target Slate specifically.
We will look at the individual [template files](https://code.ornl.gov/ryu/slate_helm_examples/-/tree/prout-dev/charts%2Fminio-standalone%2Ftemplates) in this minio-standalone chart, the deploy the application in your project space at the end.
## Prerequisites
NOTE: This example will be done on Slate's Marble Cluster. Marble resides in OLCF's Moderate enclave, a peripheral system to Summit.

### Create the Persistent Volume Claim
### The Persistent Volume Claim
Minio needs persistent storage to store objects. Without persistent storage, the data stored in an application instance will be stored in the container file system, which will be destroyed as soon as the container restarts. This is true for any application needing to persist data on Slate. So, to persist data in your application, use a persistent volume claim, or "PVC".
