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.

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, to gain basic familiarity with the application/chart building blocks, then deploy the application in your Slate namespace.

**NOTE:** The main objective of this example is to show how the smaller, individual core, components come together to create a simple application deployment. This example can be used to build off of, for a variety of data applications, but it is not meant to be a production deployment. A production deployment may require more thought and robust configurations. 

      cpu: 2

      memory: 1Gi

```

**NOTE**: Please make sure you rename your ```minio.host``` value. This needs to be unique.

### Install the Chart

First, clone the repo to your local system. Then, 'cd' into 'slate_helm_examples/charts'.

```

cd slate_helm_examples/charts

```

Log into Slate's Marble cluster with the OC CLI Tool.

```

oc login https://api.marble.ccs.ornl.gov

```

You should see a response similar to this, seeing your available project namespace(s):

```

Login successful.

You have one project on this server: "stf007"

Using project "stf007".

```

Run simple Helm command to make sure it works properly (assuming the use of helm3):

```

helm ls

```

Output will be similar, depending on if you have any existing applications (may be empty):

```

NAME                              NAMESPACE REVISION  UPDATED                               STATUS    CHART                   APP VERSION

gitlab-runner-for-slate-examples  stf007    9         2020-05-18 11:31:08.3245 -0400 EDT    deployed  gitlab-runner-0.16.1    12.10.2    

minio-standalone                  stf007    4         2020-05-19 13:00:38.165911 -0400 EDT  deployed  minio-standalone-1.0.0

```

Use helm to install the application into your namespace/project:

```

helm install minio-standalone minio-standalone/ --namespace <your_namespace>

```

**NOTE:** ```<your_namespace>``` is available above, from the login output, or you can run ```oc get projects``` to list your projects/namespaces.

Check your deployment:

```

helm ls

```

MinIO will take several minutes to spin up, but after a few minutes you will be able to access your MinIO applicaiton at: 

```https://<your_UID>-minio-standalone.apps.marble.ccs.ornl.gov/minio/```
