使用本机k8s python客户端与k8s运算符添加的API进行交互

Question

It's possible to talk to k8s's API, for instance talking to CoreV1Api:

from kubernetes import client, config
v1 = client.CoreV1Api()
k8s_corev1_api = client.CoreV1Api()
k8s_corev1_api.read_namespaced_service("myservice", 'default')

If I add an operator to k8s, for instance redis-operator , this operator adds an API endpoint redisfailover to k8s. Is it possible to interact with it using native k8s Python client ?

Answer 1

Yes, redisfailover is actually a Custom Resource , created by the Redis Operator. You can interact with custom resources with the CustomObjectsApi , very similarly to your above example:

api = client.CustomObjectsApi()
api.get_namespaced_custom_object(
    group='databases.spotahome.com',
    version='v1',
    namespace='default',
    plural='redisfailovers',
    name='myredisfailover'
)
