Error deploying simple docker container to Azure Kubernetes

I am new to Azure kubernetes. I’m trying to deploy a simple .net core web api to Azure Kubernetes. I just created the default weather project in VS 2019. I am able to run it in Docker locally fine. I am also able to push the image to a Azure container repository without a problem.

I get the error when I do:

kubectl apply -f .deployment.yml  

When I run kubectl get pods after the deploy I see this.

| NAME | READY | STATUS |
RESTARTS | AGE |

| test-deployment-7564d94c8f-fdz9q | 0/1 | ImagePullBackOff |
0 | 74s |

so then I ran kubectl describe pod test-deployment-7564d94c8f-fdz9q

and these are the errors coming back

Warning Failed (x4 over 15s) kubelet,
aks-agentpool-30270636-vmss000000

Failed to pull image
“ipaspoccontreg.azurecr.io/test:dev”: [rpc error: code = Unknown desc
= image operating system “windows” cannot be used on this platform, rpc error:code = Unknown desc = Error response from daemon: Get

My deployment.yml is

apiVersion: apps/v1

  name: test-deployment
spec:
  selector:
    matchLabels:
      app: test-pod
  template:

            cpu: "500m"
        ports:

and my service.yml is
