Issue with deploying Docker container to Azure Kubernetes Service

Try this:

1. Incorrect Kubernetes Context

You might be connected to the wrong cluster or context (e.g., a cluster that doesn’t support Deployments).

kubectl config current-context
kubectl get nodes

Make sure you're pointing to your AKS cluster.

2. Outdated or Misconfigured Cluster

If your cluster is very old or misconfigured, it might not support apps/v1.

• Check your cluster version:

kubectl version --short

AKS should support apps/v1 if it's running Kubernetes 1.9+.

3. Missing Kubernetes Resources

If you're using a custom resource or a stripped-down cluster, the Deployment kind might not be registered.

kubectl api-resources | grep Deployment

If nothing shows up, your cluster doesn’t recognize the Deployment kind.

4. YAML Formatting Issues

Even a small typo can cause Kubernetes to misinterpret your manifest.

• Double-check:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-deployment-name
spec:
  replicas: 1
  selector:
    matchLabels:
      app: your-app
  template:
    metadata:
      labels:
        app: your-app
    spec:
      containers:
      - name: your-container
        image: yourregistry.azurecr.io/your-image:tag
        ports:
        - containerPort: 80

5. Namespace or RBAC Issues

If you're deploying to a namespace that doesn’t exist or lacks permissions, the resource might not be recognized.

kubectl get namespaces
kubectl config set-context --current --namespace=default
