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.

The most basic command for viewing Kubernetes objects via kubectl is get . If you run kubectl get <resource-name> you will get a listing of all resources in the current namespace. If you want to get a specific resource, you can use kubectl get <resource-name> <object-name> .
Namespaces are a way to organize clusters into virtual sub-clusters — they can be helpful when different teams or projects share a Kubernetes cluster. Any number of namespaces are supported within a cluster, each logically separated from others but with the ability to communicate with each other.
The “default” Namespace In most Kubernetes distributions, the cluster comes out of the box with a Namespace called “default.” In fact, there are actually three namespaces that Kubernetes ships with: default, kube-system (used for Kubernetes components), and kube-public (used for public resources).
Add this environment variable in your deployment config.
