k8s-controller-core-resource Not able to run after cloning

Reached here from your MEDIUM article : https://medium.com/@trstringer/create-kubernetes-controllers-for-core-and-custom-resources-62fc35ad64a3

Started following README instructions, but 'go run *.go' gives me dependencies error.

I am new to GO and k8s.

I have installed GO :

MacBook$ echo $GOPATH
/Users/xxx/go_space
MacBook$ echo $GOROOT
/usr/local/opt/go/libexec
MacBook$ GOBIN
/Users/xxx/go_space/bin

Setup:

Running a 3 node Vagrant Ubuntu cluster, and using Macbook CLI to issue commands to my vagrant cluster, and communication is wired up from ~/.kube/config

MacBook$ kubectl get nodes
NAME         STATUS   ROLES    AGE     VERSION
k8s-head     Ready    master   2d14h   v1.13.3
k8s-node-1   Ready    <none>   2d14h   v1.13.3
k8s-node-2   Ready    <none>   2d14h   v1.13.3

@trstringer Any inputs on it ? Do we need some dependency file for it, which can install things ? Or I need to run the code from head Node ?

As suspected, it was dependencies not present after having bare GO compiler there< I did the following to resolve it before running > 'go run *.go' :

$ go get github.com/Sirupsen/logrus
$ go get k8s.io/apimachinery/pkg/apis/meta/v1
$ go get github.com/trstringer/k8s-controller-custom-resource/pkg/client/clientset/versioned
$ go get k8s.io/client-go/kubernetes
$ go get k8s.io/client-go/tools/clientcmd
$ go get k8s.io/client-go/tools/cache
$ go get k8s.io/client-go/util/workqueue

Thanks, @swapanshridhar info. I also tried to succeed.
