`kubernetes/examples` folder of the ozone distribution contains kubernetes deployment resource files for multiple use cases. By default the kubernetes resource files are configured to use `apache/ozone` image from the dockerhub.
|
||
|
|
|
||
|
|
To deploy it to minikube use the minikube configuration set:
|
||
|
|
|
||
|
|
```
|
||
|
|
cd kubernetes/examples/minikube
|
||
|
|
kubectl apply -f .
|
||
|
|
```
|
||
|
|
|
||
|
|
And you can check the results with
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl get pod
|
||
|
|
```
|
||
|
|
|
||
|
|
Note: the kubernetes/examples/minikube resource set is optimized for minikube usage:
|
||
|
|
|
||
|
|
* You can have multiple datanodes even if you have only one host (in a real production cluster usually you need one datanode per physical host)
|
||
|
|
* The services are published with node port
|
||
|
|
|
||
|
|
## Access the services
|
||
|
|
|
||
|
|
Now you can access any of the services. For each web endpoint an additional NodeType service is defined in the minikube k8s resource set. NodeType services are available via a generated port of any of the host nodes:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubectl get svc
|
||
|
|
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
|
||
|
|
datanode ClusterIP None <none> <none> 27s
|
||
|
|
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 118m
|
||
|
|
om ClusterIP None <none> 9874/TCP 27s
|
||
|
|
om-public NodePort 10.108.48.148 <none> 9874:32649/TCP 27s
|
||
|
|
s3g ClusterIP None <none> 9878/TCP 27s
|
||
|
|
s3g-public NodePort 10.97.133.137 <none> 9878:31880/TCP 27s
|
||
|
|
scm ClusterIP None <none> 9876/TCP 27s
|
||
|
|
scm-public NodePort 10.105.231.28 <none> 9876:32171/TCP 27s
|
||
|
|
```
|
||
|
|
|
||
|
|
Minikube contains a convenience command to access any of the NodePort services:
|
||
|
|
|
||
|
|
```
|
||
|
|
minikube service s3g-public
|
||
|
|
Opening kubernetes service default/s3g-public in default browser...
|
||
|
|
```
