Simple Kubernetes GO API

To Run this simple demo, make sure you have access to a running kubernetes cluster with kubeconfig accessible at $HOME/.kube/config

0. Setup your $GOPATH with the correct toolchain access!

1. go get all needed dependencies

-> go get k8s.io/client-go/kubernetes -> go get github.com/gin-gonic/gin -> go get github.com/ghodss/yaml -> go get github.com/stretchr/testify/assert

2. Run go build github.com/k8sApi/api to compile the API

3. Run go install github.com/k8sApi/api to install in your $GOPATH/bin

4. If steps 2. & 3. goes when then you should be able to just run k8sApi on the command line to start the kubernetes client webserver

The k8sApi web client serves the following endpoints

GET    /api/nodes
GET    /api/nodes/count
GET    /api/pods
GET    /api/pods/count

Example Request:

1. Get All pods in the cluster ->

REQUEST: curl http://localhost:9090/api/pods/kube-system

RESPONSE:

2. Get All pod count in the cluster ->

REQUEST: curl http://localhost:9090/api/pods/kube-system/count

RESPONSE "{ 'pods' : 23 }"

3. Get All nodes in the cluster ->

REQUEST: curl http://localhost:9090/api/nodes

RESPONSE:

4. Get All node count in the cluster ->

REQUEST: curl http://localhost:9090/api/nodes/count

RESPONSE "{ 'nodes' : 5 }"
