# Ch08 lab
|
||
|
|
|
||
|
|
Run the app:
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl apply -f lab/nginx/
|
||
|
|
```
|
||
|
|
|
||
|
|
Get the URL and browse:
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl get svc nginx -o jsonpath='http://{.status.loadBalancer.ingress[0].*}:8088'
|
||
|
|
```
|
||
|
|
|
||
|
|
> It works, but its just a single Pod writing logs to an EmptyDir.
|
||
|
|
|
||
|
|
## Sample Solution
|
||
|
|
|
||
|
|
My [StatefulSet](solution/nginx-statefulset.yaml) runs three Pods, with volume claim templates for storage.
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl apply -f lab/solution/nginx-statefulset.yaml
|
||
|
|
```
|
||
|
|
|
||
|
|
> Make lots of calls to the web app
|
||
|
|
|
||
|
|
I used this in Powershell:
|
||
|
|
|
||
|
|
```
|
||
|
|
for($i = 0; $i -lt 100; $i++) { curl http://localhost:8088 | Out-Null }
|
||
|
|
```
|
||
|
|
|
||
|
|
Then the [Job](solution/disk-calc-job.yaml) is configured to mount all of the PVCs used in the StatefulSet Pods.
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl apply -f lab/solution/disk-calc-job.yaml
|
||
|
|
```
|
||
|
|
|
||
|
|
When I check the logs I see this:
|
||
|
|
|
||
|
|
```
|
||
|
|
PS>kubectl logs -l job-name=disk-calc
|
||
|
|
32.0K /nginx0/access.log
|
||
|
|
24.0K /nginx1/access.log
|
||
|
|
40.0K /nginx2/access.log
|
||
|
|
```
|
||
|
|
|
||
|
|
## Teardown
|
||
|
|
|
||
|
|
Delete the lab resources by their labels:
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl delete all -l kiamol=ch08-lab
|
||
|
|
|
||
|
|
kubectl delete pvc -l kiamol=ch08-lab
|
||
|
|
```
