I think mistakenly you have checked in a binary triggerRun as part of the PR Please remove that

I think we should follow the naming convention for directory name here for cmd/triggerRun to something like cmd/triggerrun or cmd/trigger-run

yeah I agree cmd/triggerrun sounds fine to me. Though I think that can be a separate PR in order to keep this one contained.

Suggested change

	_ "k8s.io/client-go/plugin/pkg/client/auth"

Can we remove this import as its not used

[dibyom]

We actually need this one. Its contains auth plugins needed to setup the kubeclients for various k8s providers. See https://github.com/kubernetes/client-go/blob/master/examples/out-of-cluster-client-configuration/main.go#L33

e.g. https://github.com/kubernetes/client-go/blob/master/examples/out-of-cluster-client-configuration/main.go#L33

It is an interesting pattern, I'll admit 😛
