带有Azure Kubernetes服务的Azure内部负载均衡器不起作用

Question

I am trying to connect to internal load balancer using the below link: https://docs.microsoft.com/en-us/azure/aks/internal-lb

I see a non existing user in error message I am receiving:

Warning  CreatingLoadBalancerFailed  3m (x7 over 9m)  service-controller  Error creating load balancer (will retry): failed to ensure load balancer for service default/azure-vote-front: network.SubnetsClient#Get: Failure responding to request: StatusCode=403 -- Original Error: autorest/azure: Service returned an error. Status=403 Code="AuthorizationFailed" Message="The client '91c18461-XXXXXXXX---1441d7bcea67' with object id '91c18461-XXXXXXXXX-1441d7bcea67' does not have authorization to perform action 'Microsoft.Network/virtualNetworks/subnets/read' over scope '/subscriptions/996b68c3-ec32-46d4-8d0e-80c6da2c1a3b/resourceGroups/<<resource group>>/providers/Microsoft.Network/virtualNetworks/<<VNET>>/subnets/<<subnet id>>

When I search this user in my azure subscription, I do not find it. Any help shall be highly appreciated

Answer 1

When you created AKS you provided wrong credentials (or stripped permissions later). So the service principal AKS is not authorized to create that resource (which the error clearly states).

Code="AuthorizationFailed" Message="The client '91c18461-XXXXXXXX---1441d7bcea67' with object id '91c18461-XXXXXXXXX-1441d7bcea67' does not have authorization to perform action 'Microsoft.Network/virtualNetworks/subnets/read' over scope '/subscriptions/996b68c3-ec32-46d4-8d0e-80c6da2c1a3b/resourceGroups/<>/providers/Microsoft.Network/virtualNetworks/<>/subnets/<>

You can use az aks list --resource-group <your-resource-group> to find your service principal, but the error kinda gives that away.
