There are several ways to access the Kubernetes cluster:

Way	features	supporters
Kubernetes Dashboard	operate directly from the Web UI, simple and straightforward, with a low level of customization	Official support
Kubectl	command-line operation, the most complete, but more complex, suitable for further sub-assembly, custom features, version adaptation of the best	Official support
Client-go	Pull out of the client package from the Kubernetes code, easy to use, but careful to differentiate the Kubernetes API version	Official support
Client-python	Python client, Kubernetes-incubator	Official support
Java Client	Part of the FABRIC8, the kubernetes Java client	Redhat

To get the deployment list using Client-go:

Package MainImport (    "Path/filepath"    "K8s.io/client-go/tools/clientcmd"    "k8s.io/client-go/kubernetes"    "k8s.io/apimachinery/pkg/apis/meta/v1"    "FMT"Func Main () {path, err:= FilePath.
