Kubernetes monitoring - deployment error

[goudareddy26]

Hi All,

I followed the steps in doc to deploy k8s monitoring but getting error as "resource mapping not found for name: "dynakube" namespace: "dynatrace" from ".\\cloudNativeFullStack-no-version.yaml": no matches for kind "DynaKube" in version "dynatrace.com/v1beta1"
ensure CRDs are installed first"

PFA attached custom dynakube file I used, please help me to fix this issue.

I got this same error for all approaches like classicFullstack(UI and non-UI), cloudNativeFullstack.

Hello @goudareddy26 I don't saw in your output for kubectl get pods -n dynatrace the Actigate instance that should be running.

Can you please share the output of the

kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v0.13.0/kubernetes.yaml
kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v0.13.0/kubernetes-csi.yaml

kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v0.13.0/kubernetes.yaml
kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v0.13.0/kubernetes-csi.yaml

kubectl -n dynatrace wait pod --for=condition=ready --selector=app.kubernetes.io/name=dynatrace-operator,app.kubernetes.io/component=webhook --timeout=300s

Hi @DanielS ,

I ran above three commands you mentioned, they are successful, after running first two commnds(kubernetes.yaml and kubernetes-csi.yaml) Activegate pod will not be deployed only operator, webhook and oneagent-csi-driver pods will be deployed. AG and oneAgent pods will be deployed after we deploy  dynakube(cloudNativeFullstack.yaml), Iam getting error while deploying cloudNativeFullstack.yaml itself so its not deployed still.

Hi,

After system restart again I tried deploying dynakube( cloudNativeFullstack.yaml) and it worked.

But now one-agent pod is in error "CrashLoopBackOff", Iam working on it now.

Hi,
