## Introduction

This chart bootstraps a [MinIO&reg;](https://github.com/bitnami/containers/tree/main/bitnami/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.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

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

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/minio
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

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`

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### Update credentials

Bitnami charts configure credentials at first boot. Any further change in the secrets or credentials require manual intervention. Follow these instructions:

- Update the user password following [the upstream documentation](https://min.io/docs/minio/linux/administration/identity-access-management/minio-user-management.html)
- Update the password secret with the new values (replace the SECRET_NAME, USER and PASSWORD placeholders)

```shell
kubectl create secret generic SECRET_NAME --from-literal=root-user=USER --from-literal=root-password=PASSWORD --dry-run -o yaml | kubectl apply -f -
```

### Prometheus metrics

This chart can be integrated with Prometheus by setting `metrics.enabled` to `true`. This will expose MinIO(TM) native Prometheus endpoint in the service. It will have the necessary annotations to be automatically scraped by Prometheus.

#### Prometheus requirements

It is necessary to have a working installation of Prometheus or Prometheus Operator for the integration to work. Install the [Bitnami Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/prometheus) or the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) to easily have a working Prometheus in your cluster.

#### Integration with Prometheus Operator

The chart can deploy `ServiceMonitor` objects for integration with Prometheus Operator installations. To do so, set the value `metrics.serviceMonitor.enabled=true`. Ensure that the Prometheus Operator `CustomResourceDefinitions` are installed in the cluster or it will fail with the following error:

```text
no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"
```

Install the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) for having the necessary CRDs and the Prometheus Operator.

### [Rolling VS Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html)

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 greater than 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>

### 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/main/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/main/bitnami/contour) you can utilize the ingress controller to serve your application.To enable Ingress integration, set `ingress.enabled` to `true`.

The most common scenario is to have one host name mapped to the deployment. In this case, 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.

However, it is also possible to have more than one host. To facilitate this, the `ingress.extraHosts` parameter (if available) can be set with the host names specified as an array. The `ingress.extraTLS` parameter (if available) can also be used to add the TLS configuration for extra hosts.

> NOTE: For each host specified in the `ingress.extraHosts` parameter, it is necessary to set a name, path, and any annotations that the Ingress controller should know about. Not all annotations are supported by all Ingress controllers, but [this annotation reference document](https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/annotations.md) lists the annotations supported by many popular Ingress controllers.

Adding the TLS parameter (where available) will cause the chart to generate HTTPS URLs, and the  application will be available on port 443. The actual TLS secrets do not have to be generated by this chart. However, if TLS is enabled, the Ingress record will not work until the TLS secret exists.

[Learn more about Ingress controllers](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/).

### Securing traffic using TLS

This chart facilitates the creation of TLS secrets for use with the Ingress controller (although this is not mandatory). There are several common use cases:

- Generate certificate secrets based on chart parameters.
- Enable externally generated certificates.
- Manage application certificates via an external service (like [cert-manager](https://github.com/jetstack/cert-manager/)).
- Create self-signed certificates within the chart (if supported).

In the first two cases, a certificate and a key are needed. Files are expected in `.pem` format.

Here is an example of a certificate file:

> NOTE: There may be more than one certificate if there is a certificate chain.

```text
-----BEGIN CERTIFICATE-----
MIID6TCCAtGgAwIBAgIJAIaCwivkeB5EMA0GCSqGSIb3DQEBCwUAMFYxCzAJBgNV
...
jScrvkiBO65F46KioCL9h5tDvomdU1aqpI/CBzhvZn1c0ZTf87tGQR8NK7v7
-----END CERTIFICATE-----
```

Here is an example of a certificate key:

```text
-----BEGIN RSA PRIVATE KEY-----
MIIEogIBAAKCAQEAvLYcyu8f3skuRyUgeeNpeDvYBCDcgq+LsWap6zbX5f8oLqp4
...
wrj2wDbCDCFmfqnSJ+dKI3vFLlEz44sAV8jX/kd4Y6ZTQhlLbYc=
-----END RSA PRIVATE KEY-----
```

- If using Helm to manage the certificates based on the parameters, copy these values into the `certificate` and `key` values for a given `*.ingress.secrets` entry.
- If managing TLS secrets separately, it is necessary to create a TLS secret with name `INGRESS_HOSTNAME-tls` (where INGRESS_HOSTNAME is a placeholder to be replaced with the hostname you set using the `*.ingress.hostname` parameter).
- If your cluster has a [cert-manager](https://github.com/jetstack/cert-manager) add-on to automate the management and issuance of TLS certificates, add to `*.ingress.annotations` the [corresponding ones](https://cert-manager.io/docs/usage/ingress/#supported-annotations) for cert-manager.
- If using self-signed certificates created by Helm, set both `*.ingress.tls` and `*.ingress.selfSigned` to `true`.

### 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 `extraEnvVars` property.

```yaml
extraEnvVars:
  - name: MINIO_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
```

### 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.

### 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/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

### Backup and restore

To back up and restore Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using [Velero](https://velero.io/), a Kubernetes backup/restore tool. Find the instructions for using Velero in [this guide](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-backup-restore-deployments-velero-index.html).

## Persistence

The [Bitnami Object Storage based on MinIO(&reg;)](https://github.com/bitnami/containers/tree/main/bitnami/minio) image stores data at the `/bitnami/minio/data` path of the container by default.
This can be modified with the `persistence.mountPath` value which modifies the `MINIO_DATA_DIR` environment variable of the container.

The chart mounts a [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) at this location so that data within MinIO is persistent. 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`.

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 \
    oci://REGISTRY_NAME/REPOSITORY_NAME/minio
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

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 oci://REGISTRY_NAME/REPOSITORY_NAME/minio
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/minio/values.yaml)

## Upgrading

### To 14.0.0

This major bump changes the following security defaults:

- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 12.0.0

This version updates MinIO&reg; to major version 2023. All gateway features have been removed from Minio since upstream completely dropped this feature. The related options have been removed in version 12.1.0.

### 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/main/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
