Disable OneAgent Automatic Update on kubernetes cluster

Theodore_x86 — Mon, 30 Sep 2024 06:13:40 GMT

Hi everyone.

I would like to know what is the proper method to disable automatic OneAgent updates on a kubernetes cluster.

Is it via Host Group settings or via the AutoUpdate parameter on the Dynakube file?

Thank you.

Hi @Theodore_x86

It's better to use Dynakube file.
As per Dynatrace you can update Oneagents if the automatic updates are disabled through running the below commands
K8s: kubectl -n dynatrace rollout restart daemonset/<DYNAKUBE>-oneagent
OpenShift: oc -n dynatrace rollout restart daemonset/<DYNAKUBE>-oneagent
to update ActiveGates Pods: kubectl -n dynatrace rollout restart statefulset/<ACTIVEGATE-STATEFULSET-NAME>

Tip:

You should put actual names as per the current setup.

To update Dynatrace Operator using manifest for the mentioned monitoring methods : classicFullStack, applicationMonitoring, and host monitoring

execute the attached command kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v1.3.0/kubernetes.yaml

BR,

Peter.

Hi @Theodore_x86 ,

You can disable auto-updates in dynakube on this way: https://docs.dynatrace.com/docs/shortlink/auto-update-operator-components#configuration-in-dynakube

Hope it helps.

Regards,

Elena

Thank you @erh_inetum and @Peter_Youssef for your replies.

My question is if the "autoUpdate" field stops the updates or just controlls the restart of the pods, after the update has taken place. This is crucial for our infrastructure;we need to control the version of Dynatrace components installed.

Thanks!

Hi Theodore,

Welcome.

"autoUpdate" controls whether Dynatrace Operator restarts the OneAgent pods.

Elena.

So basically Updates are not suppressed! The updated version will be downloaded either way.

This is a problem....

Actually Documentation does not explain how to perform the following:

https://docs.dynatrace.com/managed/shortlink/auto-update-operator-components#configure-oneagent-auto-update

For Activegate there is a feature flag but I cannot find anything relevant for OneAgent.
