Which API?: kubernetes > get list of project ID, project name, namespace, PODs

Use case & Goal:

Applicable to both "GCP > GKE" and "Openshift". We intend to retrieve list of project ID (gce project id if apply), project name(gce project name if apply), namespace, PODs, cluster name, process group name ( if present).

Question: which API we can use to grab above? namespace is must-have info.

Hi @avrildong,

Maybe there is a more simple way but I would use the from the Enviroment Api v2 Monitored entities set.

I have just created a auto tag for Kubernetes entities.

Then I have used thre Get / entities Api with with the Entity Selector Type("Process_Group_Instance"),Tag("Kubernetes"). So I have already received the a list of kubernetes process group list.

From the list I have picked up a process group instance and checked it with the following Api call: GET / entities/({entityId}:

I have already received the properties:

Try and play with these Monitored entities API calls.

I hope it helps.

Best regards,

Mizső

@Mizső

Thanks for your approach! It works.

FYI one more approach I just got from other parties and it works too, similar principle as yours using same identifier "kubernetesNamespaces".

api/v1/entity/infrastructure/processes > identify via "kubernetesNamespaces" , no need to custom tag (save one step), just straight use that.

So as of now 2 API - either:

api/v2/entities?entitySelector=Type("Process_Group_Instance")&fields=firstSeenTms,lastSeenTms,properties,tags,managementZones , then filter by "properties"."metadata"."key" start with "KUBERNETES_%"
api/v1/entity/infrastructure/processes
