I have MariaDB running inside a Kubernetes node in Minikube in a Virtual Box on Windows. I want to try and communicate with the MariaDB pod such that I can read a table and visualize the contents inside Tableau. In order to do this I need to expose the Pod outside of Minikube, and also be able to access it through The Virtual Box.
I have not exposed the pod, but if I understand it correctly I need to write a NodePort Service to expose it outside the Minikube.
apiVersion v1
kind Service
metadata:
name: mariadb
spec:
type: NodePort
ports:
- targetPort: 80
port: 80
nodePort: 30008
selector:
app: mariadb
chart: mariadb-6.4.0
component: master
controller-revision-hash: my-release-mariadb-master-7b7cc7895
release: my-release
statefulset.kubernetes.io/pod-name: my-release-mariadb-master-0If I did not have the minikube inside a VirtualBox I should now be able to connect to the pod through the service. But in my case, how would one "open up" the Virtual Box such that I can communicate with the minikube and then the NodePort?
Thank you for any help!
In order to open the exposed service, the minikube service command can be used:
$ kubectl expose deployment hello-minikube --type=NodePort
service "hello-minikube" exposed
$ kubectl get svc
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
hello-minikube 10.0.0.102 <nodes> 8080/TCP 7s
kubernetes 10.0.0.1 <none> 443/TCP 13m
$ minikube service hello-minikube
Opening kubernetes service default/hello-minikube in default browser...This command will open the specified service in your default browser.
you can also get the url using :
$ minikube service hello-minikube --url
