Installing K10 on Azure

Prerequisites

Before installing K10 on Azure Kubernetes Service (AKS), please ensure that the install prerequisites are met.

Installing K10

K10 supports multiple options to authenticate with Azure Active Directory; including Azure Service Principal, Azure Managed Identity with a specific Client ID, and Azure Managed Identity with the default ID. Please select one of these options if you wish to provide Azure credentials through helm. If multiple credentials sets are provided, the installation will fail.

Installing K10 with Service Principal

To install on Azure with Service Principal, you need to specify Client Secret credentials including your Azure tenant, service principal client ID and service principal client secret.

$ helm install k10 kasten/k10 --namespace=kasten-io \
    --set secrets.azureTenantId=<tenantID> \
    --set secrets.azureClientId=<azureclient_id> \
    --set secrets.azureClientSecret=<azureclientsecret>

Installing K10 on Azure Stack with Service Principal

To install on Azure Stack, you need to specify your -

Azure tenant: the Azure Stack tenant ID (you'll find it in global azure portal > Azure Directory > Properties)

Service principal client ID: client ID of the app that was used to create the Kubernetes cluster (you'll find it in global azure portal > Azure Directory > App registration)

Service principal client secret: client-secret of the app that was used to create the Kubernetes cluster (you'll find it in global azure portal > Azure Directory > App registration > Certificate and secrets)

Azure Resource Group: name of the Resource Group that was created for the Kubernetes cluster

Azure subscription ID: a valid subscription in your Azure Stack tenant (if your az client has its default cloud set to your Azure Stack instance, you can obtain the first subscription ID with az account list | jq '.[0].id')

Azure Resource Manager endpoint: the resource management endpoint for this Azure Stack instance (if your az client has its default cloud set to your Azure Stack instance, you can obtain it with az cloud show | jq '.endpoints.resourceManager'. e.g., https://management.ppe5.example.com)

Active Directory endpoint: the active directory login endpoint (if your az client has its default cloud set to your Azure Stack instance, you can obtain it with az cloud show | jq '.endpoints.activeDirectory'. e.g., https://login.microsoftonline.com/)

Active Directory resource ID: the resource ID to obtain AD tokens (if your az client has its default cloud set to your Azure Stack instance, you can obtain it with az cloud show | jq '.endpoints.activeDirectoryResourceId. e.g., https://management.example.com/71fb132f-xxxx-4e60-yyyy-example47e19)

You can find more information for creating a Kubernetes cluster on Azure Stack in this Microsoft tutorial

$ helm install k10 kasten/k10 --namespace=kasten-io \
    --set secrets.azureTenantId=<tenantID> \
    --set secrets.azureClientId=<azureclientID> \
    --set secrets.azureClientSecret=<azureclientsecret> \
    --set secrets.azureResourceGroup=<resourceGroup> \
    --set secrets.azureSubscriptionID=<subscriptionID> \
    --set secrets.azureResourceMgrEndpoint=<resourceManagerEndpoint> \
    --set secrets.azureADEndpoint=<activeDirectoryEndpoint> \
    --set secrets.azureADResourceID=<activeDirectoryResourceID> \
    --set services.dashboardbff.hostNetwork=true

Installing K10 with Managed Identity

Before installing K10 with Azure Managed Identity, you need to ensure that Managed Identity is enabled on your cluster. Please note that K10 supports only single-identity nodes at the moment.

When installing K10 with Managed Identity, you have an option of installing with a specific Client ID, or to use the default ID.

To install on Azure using a specific client ID, you need to specify the client ID.

$ helm install k10 kasten/k10 --namespace=kasten-io \
    --set secrets.azureClientId=<azureclient_id> \

To install on Azure using the default Managed Identity, you need to set azure.useDefaultMSI to true.

$ helm install k10 kasten/k10 --namespace=kasten-io \
    --set azure.useDefaultMSI=true \

Installing K10 on Azure US Government Cloud (...and others)

To install K10 on Microsoft Azure US Government cloud, make sure to set the following helm options-

--set secrets.azureCloudEnvID=AzureUSGovernmentCloud

This will ensure that K10 points to appropriate endpoints. These options can also be used to specify other clouds like AzureChinaCloud and AzureGermanCloud.

Validating the Install

To validate that K10 has been installed properly, the following command can be run in K10's namespace (the install default is kasten-io) to watch for the status of all K10 pods:

$ kubectl get pods --namespace kasten-io --watch

It may take a couple of minutes for all pods to come up but all pods should ultimately display the status of Running.

$ kubectl get pods --namespace kasten-io
NAMESPACE     NAME                                    READY   STATUS    RESTARTS   AGE
kasten-io     aggregatedapis-svc-b45d98bb5-w54pr      1/1     Running   0          1m26s
kasten-io     auth-svc-8549fc9c59-9c9fb               1/1     Running   0          1m26s
kasten-io     catalog-svc-f64666fdf-5t5tv             2/2     Running   0          1m26s
...

In the unlikely scenario that pods that are stuck in any other state, please follow the support documentation to debug further.

Validate Dashboard Access

By default, the K10 dashboard will not be exposed externally. To establish a connection to it, use the following kubectl command to forward a local port to the K10 ingress port:

$ kubectl --namespace kasten-io port-forward service/gateway 8080:8000

The K10 dashboard will be available at http://127.0.0.1:8080/k10/#/.
