Deploy AIStor in an Airgapped Environment
This procedure deploys AIStor Object Store on Kubernetes clusters in an airgapped environment. An airgapped environment is a network environment that has no direct connection to external networks or the internet. Installing AIStor in an airgapped environment requires copying all required container images and Helm charts to private registries accessible within the airgapped network.
Airgap deployment consists of two phases:
- External Preparation (requires internet access): Download Helm charts and copy container images to your private registries from a system with network access to both the internet and your private registries.
- Airgapped Deployment (within airgapped environment): Install AIStor using the mirrored resources from within your airgapped Kubernetes environment.
This procedure assumes you or your organization have existing procedures and tooling for facilitating such copying. Defer to your organization’s procedures on importing data from the internet into the airgapped environment. You cannot complete the first phase without tooling to facilitate the download-and-copy steps.
This procedure requires installation of Kubernetes operators and associated resources including CustomResourceDefinitions, StatefulSets, and secrets into new or existing namespaces.
When to use this procedure
Use this deployment method when:
- Your Kubernetes cluster has no internet access to reach
helm.min.iofor charts orquay.iofor images. - Your organization requires all container images and charts to be pulled from a private registry instead of public registries, such as for security, compliance, or governance reasons.
If your Kubernetes cluster only requires using a private registry, but otherwise has internet access, use the Deploy AIStor with a Private Container Registry procedure instead.
Prerequisites
Before beginning this procedure, ensure you have the following:
- Kubernetes cluster running an in-support release
- Access to a user with broad permissions to create Kubernetes resources (CustomResourceDefinitions, StatefulSets, and secrets) into multiple new or existing namespaces
- Helm version 3.17 or later
- Private container registry accessible from the Kubernetes cluster and means to copy public images to the private registry
- Private Helm chart registry for storing Helm charts and means to copy public charts to a private registry
- Skopeo installed for copying container images
- Valid AIStor license from SUBNET

Deploy AIStor using Helm in an airgapped environment
The following procedure copies required container images and Helm charts to private registries and deploys AIStor using those resources.
Copy container images to private registry
Copy mandatory images and any optional images you need from quay.io to your private container registry.
Perform these steps from a system that has network access to both quay.io and your private registry.
In each step, replace PRIVATE_REGISTRY with the hostname and path to your private container registry.
If you use a different software or method for copying images to your private repository, defer to the documentation or procedure for that tooling.
The following commands use --override-os linux --override-arch amd64 flags to ensure images are copied for Linux AMD64 architecture.
If your Kubernetes cluster uses a different architecture (such as ARM64), replace amd64 with the appropriate architecture for your cluster.
If your private registry does not have TLS configured, add the --dest-tls-verify=false flag to each skopeo command.
For production environments, configure your registry with proper TLS certificates instead of disabling verification.

Verify that the images are accessible in your private registry.
You can use
skopeo inspectto verify each image was copied successfully:skopeo inspect docker://PRIVATE_REGISTRY/aistor/operator:RELEASE.2025-08-19T17-53-00ZIf your registry has a REST API endpoint, you can also verify using
curl:curl -k https://PRIVATE_REGISTRY/v2/_catalog curl -k https://PRIVATE_REGISTRY/v2/aistor/operator/tags/listReplace
https://withhttp://if your registry does not use TLS.
Before moving continuing the procedure, verify that all necessary components are in place:
- All required container images (operator, minio, minio-sidecar) are in your private registry
- Any optional container images for features you plan to use are in your private registry
- Helm charts are downloaded locally or pushed to your Helm chart registry
- You have verified image accessibility using
skopeo inspector registry API - If using physical media transfer, all tar archives are prepared and verified
This verification ensures you have all required resources before crossing into the airgapped environment where external resources cannot be retrieved.
Create image pull secret
From within the airgapped environment, create the image pull secret for your private container registry.
If your private container registry requires authentication, create a Kubernetes secret for pulling images.
Create the image pull secret in the aistor namespace:
kubectl create secret docker-registry private-repo-pull-secret \
--docker-server=PRIVATE_REGISTRY \
--docker-username=USERNAME \
--docker-password=PASSWORD \
--docker-email=EMAIL \
-n aistor
Replace the following values:
PRIVATE_REGISTRY: The hostname of your private container registryUSERNAME: Username for authenticating to the private container registryPASSWORD: Password for authenticating to the private container registryEMAIL: Email address associated with the container registry account
Mirror AIStor Helm charts to private registry
Perform these steps from a system with network access to both the internet and your private Helm chart registry. This step is part of the external preparation phase.
Mirror the AIStor Helm charts from the public MinIO Helm repository to your private Helm chart registry. Perform these steps from a system that has network access to both the internet and your private registry.
-
Add the MinIO Helm repository:
helm repo add minio https://helm.min.io/ helm repo update -
Pull the AIStor Helm charts locally:
helm pull minio/aistor-objectstore-operator helm pull minio/aistor-objectstoreThis downloads the chart files as
.tgzarchives to your current directory. -
Push the Helm charts to your private Helm chart registry.
Common private Helm registries include Harbor, Artifactory, ChartMuseum, and OCI-compatible registries. Many container registries also support storing Helm charts as OCI artifacts.
For non-OCI registries, consult your registry documentation for specific upload instructions.
For OCI-compatible registries, use the following commands:
helm push aistor-objectstore-operator-*.tgz oci://PRIVATE_REGISTRY/helm-charts helm push aistor-objectstore-*.tgz oci://PRIVATE_REGISTRY/helm-chartsReplace
PRIVATE_REGISTRYwith your registry hostname (for example,registry.example.com).If your registry requires authentication:
helm registry login PRIVATE_REGISTRY --username USERNAME --password PASSWORD helm push aistor-objectstore-operator-*.tgz oci://PRIVATE_REGISTRY/helm-charts helm push aistor-objectstore-*.tgz oci://PRIVATE_REGISTRY/helm-charts
Add private Helm repository
From within the airgapped environment, configure access to your private Helm charts.
Configure Helm values for private container registry
Create a Helm values file that configures AIStor to use your private container registry for pulling images.
-
Retrieve your license file.
Log in to SUBNET and select the License button in the Deployments view. Save the content of the file in a secure location for use in the next step.
-
Create a YAML manifest to customize the
private-minio/aistor-objectstore-operatorchart.Use your preferred text editor to create a YAML manifest for the chart named
aistor-objectstore-operator-values.yaml. The following YAML example configures the private container registry settings:repositories: aistor: hostname: PRIVATE_CONTAINER_REGISTRY pathPrefix: aistor/ imagePullSecrets: - name: private-repo-pull-secret minio: hostname: PRIVATE_CONTAINER_REGISTRY pathPrefix: minio/ imagePullSecrets: - name: private-repo-pull-secretReplace
PRIVATE_CONTAINER_REGISTRYwith the hostname of your private container registry (for example,registry.example.comorregistry.example.com:5000).The
repositoriessection configures the Helm chart to pull all AIStor images from your private container registry instead ofquay.io. ThepathPrefixvalue specifies the path within your container registry where you copied the images.The Helm chart uses the operator image directly in the deployment. The chart stores all other images in theobject-store-operatorconfiguration map in theaistornamespace. Do not update values in the configuration map directly becausehelm upgradeoverwrites them. Always update theaistor-objectstore-operator-values.yamlfile you use to deploy or redeploy the AIStor Operator to ensure changes persist. -
If you need to override specific image versions, add an
imagessection to the values file:images: minio: repository: aistor image: minio:RELEASE.2025-08-29T21-27-49ZThis example overrides the default
minioimage version with a different release. Refer to the AIStor Operator values reference for all available image customizations.Do not update values in theobject-store-operatorconfiguration map directly, ashelm upgradeoverwrites them. Instead, always use an custom YAML file such asaistor-objectstore-operator-values.yamlto install and upgrade AIStor. This ensures that changes persist.
Install the AIStor Operator
Install the AIStor Operator using the customized values file and your SUBNET license.
The license parameter requires the decoded JWT token value from your SUBNET license file (the value begins with eyJ...).
If successful, the command outputs a summary of installed resources.
Validate the installation by running the following command:
kubectl get all -n aistorThe output should show running pods similar to the following:
NAME READY STATUS RESTARTS AGE pod/adminjob-operator-cfc97d9f-hjbp5 1/1 Running 0 4m16s pod/object-store-operator-78c9f84b85-kmwlv 1/1 Running 0 4m16s NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/object-store-operator ClusterIP 10.43.210.230 <none> 4221/TCP 4m16s NAME READY UP-TO-DATE AVAILABLE AGE deployment.apps/adminjob-operator 1/1 1 1 4m16s deployment.apps/object-store-operator 1/1 1 1 4m16s NAME DESIRED CURRENT READY AGE replicaset.apps/adminjob-operator-cfc97d9f 1 1 1 4m16s replicaset.apps/object-store-operator-78c9f84b85 1 1 1 4m16s
Deploy an AIStor Object Store
After the Operator is running, deploy an AIStor Object Store instance.
-
Create a YAML manifest to customize the object store chart.
Use your preferred text editor to create a file named
aistor-objectstore-values.yaml. The following example has a minimal set of fields for deploying an 8x8 object store using the AIStor Volume Manager for storage provisioning:objectStore: name: primary-object-store pools: - name: pool-0 servers: 8 volumesPerServer: 8 size: 2Ti services: minio: serviceType: NodePort nodePort: 31000Modify the values to reflect your deployment requirements. Remove any default or unmodified values such that the file reflects only your changes.
-
Install the object store chart:
The command deploys an AIStor Server with the name and namespace of
primary-object-store.
Connect to the deployment
After the object store is deployed, connect to it using either the Console web interface or the AIStor Client command-line tool.
Troubleshooting
Architecture mismatch errors when copying images
If you encounter errors like no image found in image index for architecture when using Skopeo, ensure you are using the --override-os and --override-arch flags with the correct values for your Kubernetes cluster.
The images must match the architecture of your Kubernetes nodes, not the system where you run the skopeo commands.
For example, if copying from a Mac to a Linux AMD64 cluster:
skopeo copy --override-os linux --override-arch amd64 \
docker://quay.io/minio/aistor/operator:RELEASE.2025-08-19T17-53-00Z \
docker://PRIVATE_REGISTRY/aistor/operator:RELEASE.2025-08-19T17-53-00Z
TLS/SSL certificate errors
If you see errors related to certificate verification when copying images, you can use one of the following options depending on your environment:
-
For development/testing: Add
--dest-tls-verify=falseto disable TLS verification:skopeo copy --override-os linux --override-arch amd64 \ --dest-tls-verify=false \ docker://quay.io/minio/aistor/operator:RELEASE.2025-08-19T17-53-00Z \ docker://PRIVATE_REGISTRY/aistor/operator:RELEASE.2025-08-19T17-53-00Z -
For production environments: Configure your private registry with valid TLS certificates instead of disabling verification.
Connection refused or EOF errors
If Skopeo cannot connect to your private registry:
-
Verify the registry is running and accessible:
curl -k https://PRIVATE_REGISTRY/v2/This should return an empty JSON object
{}if the registry is accessible. -
Check that the hostname and port are correct in your
PRIVATE_REGISTRYvalue. -
Verify network connectivity between the system running Skopeo and the private registry.
-
If using a firewall, ensure the registry port is open.
Images fail to pull in Kubernetes
If images were copied successfully but fail to pull in your Kubernetes cluster:
-
Verify the image pull secret was created correctly:
kubectl get secret private-repo-pull-secret -n aistor -
Verify the Helm values file contains the correct registry hostname and image pull secret name.
-
Check pod events for specific error messages:
kubectl describe pod POD_NAME -n NAMESPACE -
Verify network connectivity from the Kubernetes nodes to the private registry.
