## TL;DR

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/minio
```

## Introduction

This chart bootstraps a [MinIO&reg;](https://github.com/bitnami/bitnami-docker-minio) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volume for Gateway NAS deployment scaling

## Installing the Chart

To install the chart with the release name `my-release`:

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/minio
```

These commands deploy MinIO&reg; on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
$ helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
$ helm install my-release \
  --set auth.rootUser=minio-admin \
  --set auth.rootPassword=minio-secret-password \
    bitnami/minio
```

The above command sets the MinIO&reg; Server root user and password to `minio-admin` and `minio-secret-password`, respectively.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
$ helm install my-release -f values.yaml bitnami/minio
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Distributed mode

By default, this chart provisions a MinIO&reg; server in standalone mode. You can start MinIO&reg; server in [distributed mode](https://docs.minio.io/docs/distributed-minio-quickstart-guide) with the following parameter: `mode=distributed`

This chart bootstrap MinIO&reg; server in distributed mode with 4 nodes by default. You can change the number of nodes using the `statefulset.replicaCount` parameter. For instance, you can deploy the chart with 8 nodes using the following parameters:

```console
mode=distributed
statefulset.replicaCount=8
```

You can also bootstrap MinIO&reg; server in distributed mode in several zones, and using multiple drives per node. For instance, you can deploy the chart with 2 nodes per zone on 2 zones, using 2 drives per node:

```console
mode=distributed
statefulset.replicaCount=2
statefulset.zones=2
statefulset.drivesPerNode=2
```

> Note: The total number of drives should be multiple of 4 to guarantee erasure coding. Please set a combination of nodes, and drives per node that match this condition.

### Prometheus exporter

MinIO&reg; exports Prometheus metrics at `/minio/v2/metrics/cluster`. To allow Prometheus collecting your MinIO&reg; metrics, modify the `values.yaml` adding the corresponding annotations:

```diff
- podAnnotations: {}
+ podAnnotations:
+   prometheus.io/scrape: "true"
+   prometheus.io/path: "/minio/v2/metrics/cluster"
+   prometheus.io/port: "9000"
```

> Find more information about MinIO&reg; metrics at https://docs.min.io/docs/how-to-monitor-minio-using-prometheus.html

## Persistence

The [Bitnami Object Storage based on MinIO(&reg;)](https://github.com/bitnami/bitnami-docker-minio) image stores data at the `/data` path of the container.

The chart mounts a [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) at this location. The volume is created using dynamic volume provisioning.

### Adjust permissions of persistent volume mountpoint

As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.

By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.

You can enable this initContainer by setting `volumePermissions.enabled` to `true`.

### Ingress

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as [nginx-ingress-controller](https://github.com/bitnami/charts/tree/master/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/master/bitnami/contour) you can utilize the ingress controller to serve your application.

To enable Ingress integration, set `ingress.enabled` to `true`. The `ingress.hostname` property can be used to set the host name. The `ingress.tls` parameter can be used to add the TLS configuration for this host. It is also possible to have more than one host, with a separate TLS configuration for each host. [Learn more about configuring and using Ingress](https://docs.bitnami.com/kubernetes/infrastructure/geode/configuration/configure-ingress/).

### TLS secrets

The chart also facilitates the creation of TLS secrets for use with the Ingress controller, with different options for certificate management. [Learn more about TLS secrets](https://docs.bitnami.com/kubernetes/infrastructure/geode/administration/enable-tls-ingress/).

### MinIO&reg; Gateway

MinIO&reg; can be configured as a Gateway for other other storage systems. Currently this chart supports to setup MinIO&reg; as a Gateway for the storage systems below:

- [Azure Blob Storage](https://azure.microsoft.com/en-us/services/storage/blobs/)
- [GCS](https://cloud.google.com/storage)
- NAS: Network Attached Storage
- [AWS S3](https://aws.amazon.com/s3/)

The enable this feature, install the chart setting `gateway.enabled` to `true`. You can choose the Gateway type setting the `gateway.type` parameter. For instance, to install the chart as a S3 Gateway, install the chart the using the following parameters:

```console
gateway.enabled=true
gateway.replicaCount=4
gateway.type=s3
gateway.auth.s3.serviceEndpoint=https://s3.amazonaws.com
gateway.auth.s3.accessKey=S3_ACCESS_KEY
gateway.auth.s3.secretKey=S3_SECRET_KEY
```

> Note: remember to replace the S3_ACCESS_KEY and S3_SECRET_KEY placeholders with your actual S3 access & secret keys.

Find all the available parameters to configure MinIO&reg; as a Gateway in the [Gateway parameters section](#gateway-parameters).

> Note: when using MinIO&reg; as a NAS Gateway, you need ReadWriteMany PVs to deploy multiple MinIO&reg; instances. Ensure you K8s cluster supports this kind of cluster, and install the chart setting `persistence.accessModes[0]` to `ReadWriteMany` to do so.

### Adding extra environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnv` property.

```yaml
extraEnv:
  - name: MINNIO_LOG_LEVEL
    value: DEBUG
```

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

### Sidecars and Init Containers

If you have a need for additional containers to run within the same pod as the MinIO&reg; app (e.g. an additional metrics or logging exporter), you can do so via the `sidecars` config parameter. Simply define your container according to the Kubernetes container spec.

```yaml
sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
       containerPort: 1234
```

Similarly, you can add extra init containers using the `initContainers` parameter.

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

### Deploying extra resources

There are cases where you may want to deploy extra objects, such a ConfigMap containing your app's configuration or some extra deployment with a micro service used by your app. For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter.

## Upgrading

### To 11.0.0

This version deprecates the usage of `MINIO_ACCESS_KEY` and `MINIO_SECRET_KEY` environment variables in MINIO&reg; container in favor of `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.

If you were already using the new variables, no issues are expected during upgrade.

### To 9.0.0

This version updates MinIO&reg; authentication parameters so they're aligned with the [current terminology](https://docs.min.io/minio/baremetal/security/minio-identity-management/user-management.html#minio-users-root). As a result the following parameters have been affected:

- `accessKey.password` has been renamed to `auth.rootUser`.
- `secretKey.password` has been renamed to `auth.rootPassword`.
- `accessKey.forcePassword` and `secretKey.forcePassword` have been unified into `auth.forcePassword`.
- `existingSecret`, `useCredentialsFile` and `forceNewKeys` have been renamed to `auth.existingSecret`, `auth.useCredentialsFiles` and `forceNewKeys`, respectively.

### To 8.0.0

This version updates MinIO&reg; after some major changes, affecting its Web UI. MinIO&reg; has replaced its MinIO&reg; Browser with the MinIO&reg; Console, and Web UI has been moved to a separated port. As a result the following variables have been affected:
- `service.port` has been slit into `service.ports.api` (default: 9000) and `service.ports.console` (default: 9001).
- `containerPort` has been slit into `containerPorts.api` (default: 9000) and `containerPort.console` (default: 9001).
- `service.nodePort`has been slit into `service.nodePorts.api` and `service.nodePorts.console`.
- Service port `minio` has been replaced with `minio-api` and `minio-console` with target ports minio-api and minio-console respectively.
- Liveness, readiness and startup probes now use port `minio-console` instead of `minio`.

Please note that Web UI, previously running on port 9000 will now use port 9001 leaving port 9000 for the MinIO&reg; Server API.

### To 7.0.0

This version introduces pod and container securityContext support. The previous configuration of `securityContext` has moved to `podSecurityContext` and `containerSecurityContext`. Apart from this case, no issues are expected to appear when upgrading.

### To 5.0.0

This version standardizes the way of defining Ingress rules. When configuring a single hostname for the Ingress rule, set the `ingress.hostname` value. When defining more than one, set the `ingress.extraHosts` array. Apart from this case, no issues are expected to appear when upgrading.

### To 4.1.0

This version introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/master/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.

### To 4.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

**What changes were introduced in this major version?**

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts

**Considerations when upgrading to this version**

- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
