Azure AKS

Running OpenHands Enterprise on Azure Kubernetes Service (AKS) follows the standard Helm installation, with provider-specific choices for node pools, storage, ingress and the sandbox runtime. This guide covers preparing the cluster with standard runc sandboxes. Once it is ready, follow the Helm guide to deploy using the runtime values below. Skip Installing Sysbox. Wherever the Helm guide installs or checks Sysbox, use the runc values and checks on this page instead.

The values below apply to Enterprise Helm chart 0.74.0 and Runtime API 0.10.0. Check the values for your licensed release before installing or upgrading.

For an agent-assisted installation on a dedicated test cluster, use the AKS installation skill and its setup scripts and templates.

Cluster Requirements

Requirement	Recommendation
Access	An Azure subscription and permissions to create the resource group, cluster, node pools and networking
AKS version	An AKS-supported version; verify the actual Ubuntu image and containerd version against your target Enterprise release
Sandbox OS	Ubuntu nodes using the default containerd/runc runtime
Storage class	Azure Disk CSI, such as `managed-csi`, with expansion enabled
Capacity	Sufficient regional and VM-family vCPU quota for application nodes, sandbox nodes and upgrades

Entra or Azure DevOps authentication alone does not establish subscription access. Check az account list --all and the selected subscription’s permissions. Grant the deployment identity access to create the cluster and its dependencies. Creating Azure role assignments requires additional permissions. Existing networks, private cluster access and workload identities need their own access checks. Check VM SKU restrictions as well as quota before selecting a region or availability zones. Use a dedicated resource group and explicit subscription and kubeconfig.

Node Pools

Use separate pools for application services and sandbox workloads:

General pool: runs OpenHands services and cluster add-ons. Keep application workloads here through node affinity or selectors.
Sandbox pool: an Ubuntu user node pool for agent sandboxes. Set workload=openhands-sandbox as a persistent node-pool label so new nodes match the Runtime API selector. Do not install the Sysbox DaemonSet or add its installer label.

Size both pools using the Sizing Guide and Resource Limits. Leave capacity for Kubernetes services, existing workloads and concurrent sandboxes. Check PodDisruptionBudgets before draining nodes for maintenance or upgrades.

Configure runc Sandboxes

Override the Sysbox defaults in the Enterprise chart through Helm values:

runtime-api:
  env:
    RUNTIME_CLASS: ""
    SET_HOST_USERS: "false"
    RUNTIME_NODE_SELECTOR: '{"workload":"openhands-sandbox"}'
    RUNTIME_TOLERATIONS: '[]'

An empty RUNTIME_CLASS omits runtimeClassName from new sandbox pods, using containerd’s default runtime. SET_HOST_USERS: "false" omits the hostUsers override; it does not request the Sysbox user-namespace configuration. Save these values in values-aks-runc.yaml and pass that file as the last -f argument on every install and upgrade, after your base values and feature overlays. For example:

helm upgrade --install openhands <licensed-chart-source> --version 0.74.0 \
  --namespace openhands --create-namespace \
  -f values.yaml -f values-aks-runc.yaml --timeout 10m

Use the licensed chart source from the Helm guide, and complete its namespace and Secret setup first. When enabling optional features, place their values files before values-aks-runc.yaml. Omitting these overrides can restore the chart’s Sysbox defaults and prevent new sandboxes from starting. If you add a sandbox-pool taint, configure a matching toleration instead of the empty list.

Verify a Sandbox

Sign in to OpenHands and start a conversation. Ask the agent to run pwd, write a file in its workspace and read it back.
Confirm the sandbox pod runs on the sandbox pool using the default runtime:
kubectl get pod <sandbox-pod> -n <runtime-namespace> \ -o jsonpath='{.spec.nodeName}{"\t"}{.spec.runtimeClassName}{"\t"}{.spec.hostUsers}{"\n"}'
Expect a sandbox-pool node name followed by two empty fields. Use the runtime namespace configured in your Helm values, such as openhands-runtimes.
Stop the conversation runtime, reopen the conversation and ask the agent to read the same file to confirm workspace persistence.

If a sandbox fails to start, follow the Troubleshooting guide and collect the pod events before contacting OpenHands support.

Persistent Storage

Inspect the Azure Disk CSI StorageClass:

kubectl get storageclass managed-csi -o yaml

Confirm that the class uses the Azure Disk CSI provisioner (disk.csi.azure.com) and supports the binding mode and expansion your workloads need. Azure Disk workspace PVCs use ReadWriteOnce. Configure storage explicitly for workspaces, PostgreSQL and any in-cluster object store. Merge the following settings into your base values file:

runtime-api:
  env:
    STORAGE_CLASS: managed-csi
postgresql:
  primary:
    persistence:
      storageClass: managed-csi

Account for node disk-attachment limits and availability-zone topology. Validate mounting, persisted content after reattachment, and expansion on a disposable PVC. See Azure Disk CSI provisioning.

Object Storage

Conversation/session storage is separate from workspace PVCs. Helm chart 0.74.0 supports S3-compatible and GCS filestore configuration; it does not expose an Azure Blob backend. Do not substitute Azure Blob credentials into the S3 settings. For an in-cluster store, chart 0.74.0 includes optional RustFS. Configure its persistence with Azure Disk CSI, provide the object-store credential Secret, and create the conversation bucket before starting conversations. Select an object store that meets your durability requirements and configure backup and restore. When enabling automations, configure a separate automation package bucket. The automation service can create it at startup when bucket creation is enabled.

Database

Use the External PostgreSQL guide for managed database requirements and Helm values. If choosing Azure Database for PostgreSQL, verify compatibility, TLS and network access against those requirements before deployment. For bundled PostgreSQL, set its persistence storage class as shown above.

Ingress

Run an ingress controller on the general pool. For Traefik with an Azure public load balancer, use the following Traefik Helm values:

service:
  type: LoadBalancer

Read the Service’s external IP and create a wildcard A record for your base domain. DNS can remain with another provider. For private ingress, select the appropriate Azure load-balancer configuration and verify client access separately. Follow DNS and TLS for trusted certificates and hostname configuration. Use flat runtime hostnames with Traefik standard Ingress. If provisioning certificates manually, assign renewal and Secret-update ownership.
