why this happens when I use asoctl, and kubectl apply, it shows below

wtst45x@MacBook-Pro additional % kubectl apply -f resources.yaml

so confused! new in azure, how can I resolve it

[theunrepentantgeek]

These are errors coming from your cluster because your resources.yaml file has issues - you'll need to fix those in order for kubectl to work.

Since you haven't shared resources.yaml, I can't do much to assist, but here are some pointers.

ManagedCluster.containerservice.azure.com "testcluster" is invalid: spec.owner: Required value

You haven't provided a value for the owner property with the spec of your ManagedCluster definition. From the ManagedCluster documentation, we see that owner is a reference to the owner of the cluster.

Populate this with a reference to the Azure ResourceGroup into which the cluster should be created.

ManagedClustersAgentPool.containerservice.azure.com "testcluster-agentpool" is invalid: spec.type: 
Unsupported value: "Microsoft.ContainerService/managedClusters/agentPools": 
supported values: "AvailabilitySet", "VirtualMachineScaleSets"`

For the type of your AgentPool, you need to specify either AvailablilitySet or VirtualMachineScaleSets (see documentation).

The Microsoft.ContainerService/managedClusters/agentPools you provided is the type of the Custom Resource from a Kubernetes perspective and doesn't belong within the spec. It should be set on the apiVersion line of your file.

ManagedClustersAgentPool.containerservice.azure.com "testcluster-userpool" is invalid: spec.type: 
Unsupported value: "Microsoft.ContainerService/managedClusters/agentPools": 
supported values: "AvailabilitySet", "VirtualMachineScaleSets"

This is the same problem, on your other agent pool.

Have a look at the samples we have for ManagedCluster and AgentPool, these show simple configurations that may be a useful reference.

@theunrepentantgeek still an issue for latest asoctl in that it won't populate owner field of spec when importing a ManagedCluster azure-resource.
