I want to fetch the cluster name, region, and zone of the cluster. How can I do that in python by using Kubernetes API or tell me if we have any other method to fetch data, I didn't find any documents related to that.

Hello @Tushar Sharma !

Thank you for raising this question!

The recommended way to fetch this data is via azure cli. You can use "az aks show" command together with "--query parameter" and output as tsv. To be handy for you, I prepared the commands for your needs (name, region and availability zone):

az aks show -g resourceGroupName -n clusterName --query "name" -o tsv

az aks show -g resourceGroupName -n clusterName --query "location" -o tsv

az aks show -g resourceGroupName -n clusterName --query "agentPoolProfiles[].availabilityZones" -o tsv

I hope this answers your question.

Here in the above solution, we are providing the value of cluster name then only we are getting the desired result. Is there any other way to fetch the data like this in AWS https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-identity-documents.html and gcp https://cloud.google.com/kubernetes-engine/docs/reference/rest/v1/projects.zones.clusters/get

Hi @Tushar Sharma ,

Following to Andrei's answer, using python you can have something like:

from azure.mgmt.containerservice import ContainerServiceClient  
from azure.identity import AzureCliCredential  
  
  
credential = AzureCliCredential()  
  
# Replace the value of resource_group with the name of your resource group  
subscription_id='your-subid'  
resource_group = 'rg-name'  
aks_name= 'cluster-name'  
  
client=ContainerServiceClient(credential,subscription_id)  
  
aks=client.managed_clusters.get(resource_group_name=resource_group,resource_name=aks_name)  
cluster_name = aks.name  
region = aks.location  
zone = aks.agent_pool_profiles[0].availability_zones  
  
# Print the AKS cluster information  
print(f'Cluster name: {cluster_name}')  
print(f'Region: {region}')  
print(f'Zone: {zone}')

You can refer to https://github.com/Azure-Samples/azure-samples-python-management/tree/main/samples/containerservice for examples.
Also, keep in mind that the zone depends on the node pool, so you might want to loop over the agent pools (in my example I just printed the first one).

Hope this helps !
