Oneagent - Dynakube deployment fails for K8s arm64 nodes

amr_1509 — Mon, 06 May 2024 13:42:43 GMT

I am trying to deploy dynakube for arm64 nodes and i am getting the below error:

[2024-04-30 10:58:10.427 UTC] [0004cfb7] [info ] [bootstrapper] Started agent deployment as a container, PID 315319 [2024-04-30 10:58:10.427 UTC] [0004cfb7] [error ] [bootstrapper] Read-only mode is supported only with volume-based storage

Can someone provide some insights to fix this?

But the same configuration works just fine for amd64 nodes. I am using the image tailored for arm64 nodes. Here is my dynakube config:

apiVersion: dynatrace.com/v1beta1 kind: DynaKube metadata: name: oa-arm namespace: dynatrace annotations: feature.dynatrace.com/automatic-kubernetes-api-monitoring: "true" feature.dynatrace.com/oneagent-readonly-host-fs: "false" feature.dynatrace.com/automatic-injection: "false" spec: apiUrl: https://{environmentid}.live.dynatrace.com/api tokens: "XXXXXXX" skipCertCheck: false namespaceSelector: matchLabels: dynatrace.com/inject: "true" oneAgent: cloudNativeFullStack: image: "dynatrace/dynatrace-oneagent:1.277.204.20231129-185056" version: "" initResources: {} nodeSelector: kubernetes.io/arch: arm64 tolerations: - effect: NoSchedule key: node-role.kubernetes.io/master operator: Exists - effect: NoSchedule key: node-role.kubernetes.io/control-plane operator: Exists oneAgentResources: {} args: - --set-monitoring-mode=fullstack - --set-host-group=oa-arm env: - name: ONEAGENT_ENABLE_VOLUME_STORAGE value: "false" autoUpdate: true priorityClassName: "" dnsPolicy: "" labels: {}

Hi AMR / Cyanogen,

looks like a config issue around your storage type.
probably related to the feature & setting environment

ONEAGENT_ENABLE_VOLUME_STORAGE

cloud native full stack uses CSI compared to One Agent.
Perhaps try flipping back to default config and see how you go.
dynatrace-operator/assets/samples/dynakube/v1beta2/cloudNativeFullStack.yaml at main · Dynatrace/dynatrace-operator · GitHub

Also make sure that you have the correct image type

Good luck
