如何获取集群内Go Kubernetes客户端的当前名​​称空间

How do I get the current namespace of a deployment/service using the kubernetes client-go API? It doesn't seem to be in the client object or in the config.

You can always set the context for each namespace and then read from kubeconfig on which context you are currently on:

Use the following code to find out on which namespace you are on:

namespace, _, err := kubeconfig.Namespace()
    if err != nil {
            panic(err)
    }

This will return the namespace in which you're.

For more information refer :

https://github.com/kubernetes/client-go/blob/master/tools/clientcmd/client_config.go

Using

ioutil.ReadFile("/var/run/secrets/kubernetes.io/serviceaccount/namespace")

works but is ugly, when the desired implementation is present in the Namespace() method of inClusterClientConfig. But how would you get that object starting from rest.InClusterConfig()? It is only instantiable from outside the package via NewNonInteractiveDeferredLoadingClientConfig.

I see kubernetes #63707 which looks related but was abandoned.
