And test that you can actually reach the test nginx service across continents
```
$ kubectl config use-context <clustername_us>
$ kubectl -it exec curlpod -- /bin/sh
[ root@curlpod:/ ]$ curl http://10.244.0.4:80
Europe nginx
```
## Granting access to the remote cluster
We will grant the US cluster access to the Europe cluster. Basically we're going to setup a secret that allows kubectl to function in a pod running in the US cluster, just like it did on our local machine in the previous step. First create a secret with the contents of the current .kube/config:
```shell
$ kubectl config use-context <clustername_eu>
$ go run ./make_secret.go --kubeconfig=$HOME/.kube/config > /tmp/secret.json
$ kubectl config use-context <clustername_us>
$ kubectl create -f /tmp/secret.json
```
Create a kubectl pod that uses the secret, in the US cluster.
```json
{
"kind": "Pod",
"apiVersion": "v1",
"metadata": {
"name": "kubectl-tester"
},
"spec": {
"volumes": [
{
"name": "secret-volume",
"secret": {
"secretName": "kubeconfig"
}
}
],
"containers": [
{
"name": "kubectl",
"image": "bprashanth/kubectl:0.0",
"imagePullPolicy": "Always",
"env": [
{
"name": "KUBECONFIG",
"value": "/.kube/config"
}
],
"args": [
"proxy", "-p", "8001"
],
"volumeMounts": [
{
"name": "secret-volume",
"mountPath": "/.kube"
}
]
}
]
}
}
```
And check that you can access the remote cluster
```shell
$ kubectl config use-context <clustername_us>
$ kubectl exec -it kubectl-tester bash
kubectl-tester $ kubectl get nodes
NAME LABELS STATUS
eu-node-0n61 kubernetes.io/hostname=eu-node-0n61 Ready
eu-node-79ua kubernetes.io/hostname=eu-node-79ua Ready
eu-node-7wz7 kubernetes.io/hostname=eu-node-7wz7 Ready
eu-node-loh2 kubernetes.io/hostname=eu-node-loh2 Ready
```
