How to Get Azure Stack HCI AKS Worker Node Status via REST API?

Akash Sharma 0

Can anyone explain the difference between a Hybrid Container Service and a Hybrid Kubernetes REST API?
Which one is better for AKS running on Azure Stack HCI? Also, is there a REST API that can provide the status of worker nodes?

Hi Akash Sharma,
Thank you for your patience while we are reviewing your query.

Azure Kubernetes Service (AKS) on Azure Stack HCI and Windows Server is an on-premises Kubernetes implementation of AKS. AKS on Azure Stack HCI and Windows Server automates running containerized applications at scale. AKS enabled by Azure Arc manages your hosted Kubernetes environment, making it quick and easy to deploy and manage containerized applications without container orchestration expertise. It also eliminates the burden of ongoing operations and maintenance by provisioning, upgrading, and scaling resources on demand, without taking your applications offline.
https://learn.microsoft.com/en-us/rest/api/hybridcontainer/?view=rest-hybridkubernetes-2024-01-01

Hybrid Kubernetes Service allows you to manage your on-premises Kubernetes clusters from azure by onboarding them to Azure Arc. The Hybrid Kubernetes API allows you to create, list, update and delete your Arc enabled Kubernetes clusters.
completely supported by Microsoft.
https://learn.microsoft.com/en-us/rest/api/hybridkubernetes/?view=rest-hybridkubernetes-2024-01-01
If your primary goal is to manage Kubernetes clusters and their resources, the Hybrid Kubernetes REST API would be more suitable. It provides direct access to Kubernetes functionalities and is tailored for managing Kubernetes resources effectively. If you are looking for a broader solution that includes container management, then a Hybrid Container Service might be more appropriate.

Hi,

Thanks for reply.

https://learn.microsoft.com/en-us/rest/api/stackhci/clusters/get?view=rest-stackhci-2024-01-01&tabs=HTTP
I Think this api for azure stack hci cluster and Node. Note for AKS Node.
Is there any rest api to get health of aks worker node?

Hi Akash Sharma,

Thank you for reaching back again! You can use Azure Kubernetes Service (AKS) with the Kubernetes API to access metadata such as pods, workspaces, and nodes. The Kubernetes endpoints are accessed using the cluster server address and an authorization token.

For reference, here is the documentation link: Kubernetes API Concepts

Hi Mounika Reddy Anumandla,
Thanks for reply,

What if we want the status of the worker node, control plane API endpoint health, and etcd health? Is it possible to collect this data using a REST API, or is there any other solution to gather this information via REST API?

Hi Akash Sharma,

Thank you for replying back. Hope the below information helps!

You can query the Kubernetes API to get node information using the /api/v1/nodes endpoint. GET /api/v1/nodes.
You can also use Azure Monitor to track the health and performance of worker nodes. Azure provides several built-in metrics like CPU usage, memory usage, etc., which can help you monitor the health of the AKS nodes. Azure Monitor can be queried using the Azure REST API.

Use the healthz endpoint of the Kubernetes API to check the overall health of the control plane. The control plane will respond with a 200 OK status if healthy. GET /healthz - This will provide the health status of the API server (control plane).
Azure also offers built-in integration with Azure Monitor to provide insights into the status of the AKS control plane, such as any incidents or downtime. You can use the Azure Monitor REST API to query and fetch data related to the health of AKS.

In AKS, you don’t directly manage etcd, but it is managed by Azure. However, in AKS, etcd health checks are managed by Azure and not directly exposed via an API for users. For AKS, Azure provides logs and metrics through Azure Monitor and Log Analytics, which can give insights into the health of components like etcd indirectly by monitoring the overall health of the cluster and control plane. While AKS does not provide a single REST API endpoint for all health information, Azure Monitor offers its own REST API that allows you to query and retrieve health metrics and logs, making it easier to integrate monitoring into your applications or workflows.
