无法从 Ansible 连接到 AWS EKS

Question

我在 ansible 中使用以下 yaml 文件连接到 AWS EKS

- name: Deploy app in new namespace   
  hosts: localhost   
  tasks:
    - name: Create a k8s namespace
      k8s:
        name: my-app
        api_version: v1
        kind: Namespace
        state: present
        kubeconfig: /home/hossam/Documents/eks-terraform-ansible/kubeconfig_myapp-eks-cluster

但我无法连接到集群，总是得到以下结果

[WARNING]: provided hosts list is empty, only localhost is available. Note that
the implicit localhost does not match 'all'

解决办法是将Kubernetes版本降级到v11.0.0

pip3 install -Iv kubernetes==11.0.0
