MinIO Helm Charts

Hyperscale Object Store for AI

MinIO AIStor is designed to allow enterprises to consolidate all of their data on a single, private cloud namespace. Architected using the same principles as the hyperscalers, AIStor delivers performance at scale at a fraction of the cost compared to the public cloud.

AIStor runs in Kubernetes.

Pre-requisites

• An active Kubernetes environment running a maintained version
• kubectl CLI tool
• helm CLI tool
• oc CLI tool if you are using Openshift

Environment

You can run MinIO Helm charts on Kubernetes providers such as

• Redhat Openshift
• Upstream Kubernetes
• Google Kubernetes Engine
• Amazon Elastic Kubernetes Service
• Azure Kubernetes Service

Other Kubernetes providers may also work.

MinIO Helm charts Repo

helm.min.io repo is the official MinIO Helm repo for the enterprise products. You can add it with the following command:

helm repo add minio https://helm.min.io/
helm repo update

When you add the repo, you can see the available charts with the following command:

helm search repo minio

AIStor Volume Manager

AIStor Volume Manager is a CSI driver for Direct Attached Storage, minio/aistor-volumemanager is the AIStor Volume Manager chart.

You can install the AIStor Volume Manager CSI with the following command:

helm install directpv minio/aistor-volumemanager \
  --set global.license="<your-license-key>"

AIStor Object Store Operator

minio/aistor-objectstore-operator is the AIStor Object Store operators chart, by default, it will install only 2 operators:

• AIStor Object Store Operator
• AIStor AdminJob Operator

You can install the AIStor operators with the following commands:

helm install aistor minio/aistor-objectstore-operator \
  --namespace aistor --create-namespace \
  --set global.license="<your-license-key>"

🔐 License Configuration

To use the aistor-objectstore-operator, you must pass a valid license via the global.license field.

⚠️ Important: Do not pass the encrypted license block (starts with ZXlK...). The operator expects a valid JWT string (typically starts with eyJ...).

✅ Correct usage (decoded JWT):

helm install aistor minio/aistor-objectstore-operator \
  --namespace aistor --create-namespace \
  --set global.license="eyJhbGciOiJFUzM4NCIsInR5cCI6IkpXVCJ9..."

❌ Incorrect usage (encrypted blob):

helm install aistor minio/aistor-objectstore-operator \
  --namespace aistor --create-namespace \
  --set global.license="ZXlKaGJHY2lPaUpGVXpNNE5DSXNJ..."

If you are unsure how to get the decoded license token (JWT), please contact your support representative or open a SUBNET request.

AIStor Object Store

Now you are ready to create your own AIStor object store, get the values.yaml file from the chart and edit it to your needs.

helm show values minio/aistor-objectstore > values.yaml

Finally, create the object store with the following command:

helm install my-objectstore minio/aistor-objectstore \
  --namespace my-objectstore \
  --create-namespace \
  -f values.yaml 

AIStor Key Manager Operator

The AIStor Key Manager Operator is responsible for managing the AIStor Key Manager. To install the AIStor Key Manager Operator, you can use the following command:

helm install keymanager-operator minio/aistor-keymanager-operator \
  --namespace keymanager \
  --create-namespace  \
  --set global.license="<your-license-key>"

AIStor Key Manager

Once Key Manager Operator is installed, you can create your own AIStor Key Manager, get the values.yaml file from the chart and edit it to your needs.

helm show values minio/aistor-keymanager > values.yaml

Next, you want to create the HSM master key, in order to do that, you need to create it running the minkms command, this is possible running it from the container:

docker run quay.io/minio/aistor/minkms:latest --soft-hsm
hsm:aes256:HSMKEYVALUE

Finally, create the Key Manager with the following command, please replace the HSMKEYVALUE with the value generated by the minkms --soft-hsm command:

helm install my-keymanager minio/aistor-keymanager \
  --namespace my-keymanager \
  --create-namespace \
  --set  hsm.hsm="hsm:aes256:HSMKEYVALUE"

Replace the HSMKEYVALUE with the value generated by the minkms --soft-hsm command.

AIStor AIHub Operator

The AIStor AIHub Operator is responsible for managing the AIStor AIHub. To install the AIStor AIHub Operator, you can use the following command to opt-in to the AIStor AIHub Operator in the minio/aistor-objectstore-operator Helm chart:

helm install aistor minio/aistor-objectstore-operator \
  --namespace aistor \
  --create-namespace \
  --set global.license="<your-license-key>" \
  --set operators.object-store.disabled=true \
  --set operators.adminjob.disabled=true \
  --set operators.aihub.disabled=false

AIStor Prompt Operator

The AIStor Prompt Operator is responsible for managing the AIStor Prompt. To install the AIStor Prompt Operator, you can use the following command to opt-in to the AIStor AIHub Operator in the minio/aistor-objectstore-operator Helm chart:

helm install aistor minio/aistor-objectstore-operator \
  --namespace aistor \
  --create-namespace \
  --set global.license="<your-license-key>" \
  --set operators.object-store.disabled=true \
  --set operators.adminjob.disabled=true \
  --set operators.prompt.disabled=false

  --set operators.object-store.disabled=true \
  --set operators.adminjob.disabled=true \
  --set operators.warp.disabled=false
