我对 Kubernetes 还比较陌生,我需要使用 Kubernetes python-client 创建一个 Pod。 所以为了进行实验,我正在尝试运行项目提供的示例笔记本,而不做任何更改,看看事情是如何工作的。
从第三步开始使用intro_notebook.ipynb,我遇到了一个错误:
ValueError: Invalid value for `selector`, must not be `None`
这里是代码:
from kubernetes import client, config
我改变的唯一部分是第二个单元格,因为我正在使用Ubuntu的microk8s
运行Kubernetes:
config.load_kube_config('/var/snap/microk8s/current/credentials/client.config')
api_instance = client.AppsV1Api()
dep = client.V1Deployment()
spec = client.V1DeploymentSpec() # <<< At this line I hit the error!

$ pip freeze | grep -e kuber

$ snap list microk8s

更新
将microk8s降级到v1.15.11并没有解决问题。
