Hello the ditto api url is not opening

I guess you were installing the cloud2edge chart here.

I've just tested the cloud2edge chart installation in minikube and see ditto containers not getting ready.
In the ditto-gateway container, I see errors like

{"timestamp":"2024-05-06T22:46:06.635+02:00","version":"1","message":"Probing [http://10-244-10-40.cloud2edge.pod.cluster.local:7626/bootstrap/seed-nodes] failed due to: Probing timeout of [http://10-244-10-40.cloud2edge.pod.cluster.local:7626]","logger_name":"org.apache.pekko.management.cluster.bootstrap.internal.HttpContactPointBootstrap","thread_name":"ditto-cluster-pekko.actor.default-dispatcher-7","level":"WARN","level_value":30000,"sourceThread":"ditto-cluster-pekko.actor.default-dispatcher-13","pekkoAddress":"pekko://[email protected]:2551","pekkoSource":"pekko://[email protected]:2551/system/bootstrapCoordinator/contactPointProbe-10-244-10-40.cloud2edge.pod.cluster.local-7626"}

I haven't seen this when previously installing this cloud2edge chart version.
The issue also occurs when just installing the ditto chart in the version used by the c2e chart (helm install -n ditto my-ditto oci://registry-1.docker.io/eclipse/ditto --version 3.4.4 --wait).
I'll be doing some further tests here, also integrating the latest ditto chart version.

As it turned out, there was a general issue with DNS resolution in my minikube cluster, unrelated to the helm charts. It caused host names like 10-244-10-40.cloud2edge.pod.cluster.local to be not resolved correctly. After fixing this (had to change the /etc/resolv.conf via minikube ssh), the ditto pods got ready again.

@charanhs123 To see what the issue is in your case, you can first check the status of the ditto pods:

$ kubectl get pods -n cloud2edge 
NAME                                                READY   STATUS    RESTARTS      AGE

If pod containers are not ready (especially the ditto-gateway), you can run

kubectl describe pod -n cloud2edge c2e-ditto-gateway-9d5b747c4-hgkdc

and check the container status, e.g.

Containers:
  ditto-gateway:
    Container ID:   docker://011c47291dae3781dff897b82a9cd8ee246c1167d97357d1f9904f78dc858a36

      Finished:     Thu, 09 May 2024 14:15:28 +0200
    Ready:          True

and the events at the bottom of the output.
And check the logs of the pod:

kubectl logs -n cloud2edge c2e-ditto-gateway-9d5b747c4-hgkdc

searching for "level":"ERROR" in there.
(Also be sure that you have enough memory/disk space for your kubernetes cluster (see requirements here.)
