MultiJuicer doesn't run on microk8s without ClusterDNS enabled about multi-juicer

[J12934]

Hi 👋
Can you check if Kubernetes has properly marked the pods as ready:

kubectl get deployments
kubectl get pods

To help out more it would also be importatnt to know what sort of cluster you are using (cloud / on-prem) and which kubernetes version you are using.

I'm using microk8s on a CentOS 8.

microk8s kubectl version:

Client Version: version.Info{Major:"1", Minor:"19+", GitVersion:"v1.19.5-34+8af48932a5ef06", GitCommit:"8af48932a5ef06681503866c4ce23d302321a9c8", GitTreeState:"clean", BuildDate:"2020-12-09T19:59:08Z", GoVersion:"go1.15.6", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"19+", GitVersion:"v1.19.5-34+8af48932a5ef06", GitCommit:"8af48932a5ef06681503866c4ce23d302321a9c8", GitTreeState:"clean", BuildDate:"2020-12-09T20:00:05Z", GoVersion:"go1.15.6", Compiler:"gc", Platform:"linux/amd64"}

The pods are currently marked as ready.

microk8s kubectl get deployments:

microk8s kubectl get pods:

Can you try to enable cluster dns in the microk8s cluster?
The balancer tries to proxy the requests to the juice shop instances via their service names. If it cant resolve the service names than the proxing doesn't work correctly.

I enabled dns but I still can't access on the Juice Shop instance.

Enabled Dns with:

microk8s enable dns

[J12934]

Can you try creating a new instance?
If that doesn't work, try reinstalling MultiJuicer

We've had a similar issues reported with microk8s on slack where installing the dns did solve the issue: https://owasp.slack.com/archives/C255XSY04/p1592308987095900

[mistersso]

Well I solved the issue. The problem was that microk8s enable dns could not create the CoreDns correctly because the ClusterIP was already allocated. I removed the other service and now I can fully access on Juice-Shop. The next step will be to implement the Multi-Juicer with the monitoring setup.

Thank you 👍

Okay nice 👍
