Deploy to kubernetes
kubernetes/examples folder of the ozone distribution contains kubernetes deployment resource files for multiple use cases.
To deploy it to minikube use the minikube configuration set:
Code Block |
---|
cd kubernetes/examples/minikube
kubectl apply -f . |
And you can check the results with
Code Block |
---|
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 publish 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:
Code Block |
---|
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
