@ -12,79 +12,6 @@ Introduction
This chart bootstraps MinIO deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Prerequisites
-------------
- Kubernetes 1.4+ with Beta APIs enabled for default standalone mode.
- Kubernetes 1.5+ with Beta APIs enabled to run MinIO in [distributed mode](#distributed-minio).
- PV provisioner support in the underlying infrastructure.
Configure MinIO Helm repo
--------------------
```bash
$ helm repo add minio https://helm.min.io/
```
Installing the Chart
--------------------
Install this chart using:
```bash
$ helm install --namespace minio --generate-name minio/minio
```
The command deploys MinIO on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
### Release name
An instance of a chart running in a Kubernetes cluster is called a release. Each release is identified by a unique name within the cluster. Helm automatically assigns a unique release name after installing the chart. You can also set your preferred name by:
```bash
$ helm install my-release minio/minio
```
### Access and Secret keys
By default a pre-generated access and secret key will be used. To override the default keys, pass the access and secret keys as arguments to helm install.
```bash
$ helm install --set accessKey=myaccesskey,secretKey=mysecretkey --generate-name minio/minio
```
Uninstalling the Chart
----------------------
Assuming your release is named as `my-release`, delete it using the command:
```bash
$ helm delete my-release
```
or
```bash
$ helm uninstall my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
Upgrading the Chart
-------------------
You can use Helm to update MinIO version in a live release. Assuming your release is named as `my-release`, get the values using the command:
```bash
$ helm get values my-release > old_values.yaml
```
Then change the field `image.tag` in `old_values.yaml` file with MinIO image tag you want to use. Now update the chart using
```bash
$ helm upgrade -f old_values.yaml my-release minio/minio
```
Default upgrade strategies are specified in the `values.yaml` file. Update these fields if you'd like to use a different strategy.
Configuration
