== Running a Deployment using this volume == | |||
Now that we know how to persistently store data and access it from Pods, it's time to create an actual Deployment with a real-world application in it. | |||
For this, I use the following tutorial: https://kubernetes.io/docs/tasks/run-application/run-stateless-application-deployment/ - binding /persistent/html to /usr/share/nginx/html inside the containers: | |||
<pre> | |||
apiVersion: apps/v1 | |||
kind: Deployment | |||
metadata: | |||
name: nginx-deployment | |||
spec: | |||
selector: | |||
matchLabels: | |||
app: nginx | |||
replicas: 2 | |||
template: | |||
metadata: | |||
labels: | |||
app: nginx | |||
spec: | |||
volumes: | |||
- name: websource | |||
nfs: | |||
path: /persistent/html | |||
server: <ipaddress> | |||
containers: | |||
- name: nginx | |||
image: nginx:1.7.9 | |||
ports: | |||
- containerPort: 80 | |||
volumeMounts: | |||
- mountPath: /usr/share/nginx/html | |||
name: websource | |||
</pre> | |||
Now, before starting this deployment, make an example web page by creating <code>/persistent/html/index.html</code> with something like: | |||
<pre> | |||
<nowiki><h1>It's working!</h1></nowiki> | |||
</pre> | |||
Then, start the deployment: | |||
<pre> | |||
$ kubectl apply -f nginx.yaml | |||
</pre> | |||
