Unable to pull kubernetes image

I’m testing the Kubernetes installation, but I’m having some problems to download the images.
I’m getting a forbidden message when pulling it.

Basically the Kubernetes installation is just:

kubectl apply -f https://bit.ly/kong-ingress-dbless

As far as I was to check, it tries to pull the image from:

image: kong-docker-kubernetes-ingress-controller.bintray.io/kong-ingress-controller:0.9.0

I believe this is a proxy issue and I just need to whitelist the urls on the proxy.
So far, I have requested this changes:

But, I’m still not able to pull the complete image, what else I’m missing?

Thanks

@biancoda Were you able to solve the issue?
What are the events you see in the kong pod?
