## Testing your Kubernetes cluster.
|
||
|
|
|
||
|
|
To validate that your node(s) have been added, run:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
kubectl get nodes
|
||
|
|
```
|
||
|
|
|
||
|
|
That should show something like:
|
||
|
|
```
|
||
|
|
NAME LABELS STATUS
|
||
|
|
10.240.99.26 <none> Ready
|
||
|
|
127.0.0.1 <none> Ready
|
||
|
|
```
|
||
|
|
|
||
|
|
If the status of any node is ```Unknown``` or ```NotReady``` your cluster is broken, double check that all containers are running properly, and if all else fails, contact us on IRC at
|
||
|
|
```#google-containers``` for advice.
|
||
|
|
|
||
|
|
### Run an application
|
||
|
|
```sh
|
||
|
|
kubectl -s http://localhost:8080 run-container nginx --image=nginx --port=80
|
||
|
|
```
|
||
|
|
|
||
|
|
now run ```docker ps``` you should see nginx running. You may need to wait a few minutes for the image to get pulled.
|
||
|
|
|
||
|
|
### Expose it as a service:
|
||
|
|
```sh
|
||
|
|
kubectl expose rc nginx --port=80
|
||
|
|
```
|
||
|
|
|
||
|
|
This should print:
|
||
|
|
```
|
||
|
|
NAME LABELS SELECTOR IP PORT(S)
|
||
|
|
nginx <none> run-container=nginx <ip-addr> 80/TCP
|
||
|
|
```
|
||
|
|
|
||
|
|
Hit the webserver:
|
||
|
|
```sh
|
||
|
|
curl <insert-ip-from-above-here>
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that you will need run this curl command on your boot2docker VM if you are running on OS X.
|
||
|
|
|
||
|
|
### Scaling
|
||
|
|
|
||
|
|
Now try to scale up the nginx you created before:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
kubectl resize rc nginx --replicas=3
|
||
|
|
```
|
||
|
|
|
||
|
|
And list the pods
|
||
|
|
|
||
|
|
```sh
|
||
|
|
kubectl get pods
|
||
|
|
```
|
||
|
|
|
||
|
|
You should see pods landing on the newly added machine.
