SCENARIO 2.1: Pacman's installation

#########################################################################################

Pacman is essentially a NodeJS application that uses a MongoDB database to store its scores.
More details about it can be found on the following links:

Let's deploy Pacman on the cluster RKE2:

$ rke2
$ kubectl create -f pacman.yaml
namespace/pacman2 created
persistentvolumeclaim/mongo-storage created
service/mongo created
deployment.apps/mongo created
service/pacman created
deployment.apps/pacman created

$ kubectl get -n pacman pod,pvc,svc
NAME                          READY   STATUS    RESTARTS   AGE
pod/mongo-747b5dbbd6-x4jpm    1/1     Running   0          17s
pod/pacman-5668696796-f6dz9   1/1     Running   0          17s

NAME                                  STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
persistentvolumeclaim/mongo-storage   Bound    pvc-739642ae-827c-44cc-b46b-a8a163bbe870   8Gi        RWO            sc-nas-svm2    17s

NAME             TYPE           CLUSTER-IP       EXTERNAL-IP     PORT(S)           AGE
service/mongo    LoadBalancer   172.28.234.217   192.168.0.233   27017:30820/TCP   17s
service/pacman   LoadBalancer   172.28.234.93    192.168.0.234   80:32730/TCP      17s

In my example, Pacman is available on the 192.168.0.234 address.
Let's give it a try!

Time to have fun, play a few games & enter some names for the high scores.
In my case, I have:

You can also check that the highscores have been properly entered in the database with the following command:

$ kubectl exec -it -n pacman $(kubectl get pod -n pacman -l "name=mongo" -o name) -- mongo --eval 'db.highscore.find().pretty()' pacman
MongoDB shell version: 3.2.21
connecting to: pacman

	"ip_addr" : "::ffff:192.168.0.223"
}

Now that some scores are saved on the database, you can proceed with managing the app with Astra Control
