Assign Specific Pods to Certain Nodes in Dynatrace Kubernetes Deployment

[agylpradipta]

Hello All,

Regarding the Dynatrace deployment for Kubernetes, there are several pods that will be formed:

• dynakube-activegate-0
• dynatrace-operator-xxxx
• dynatrace-webhook-xxx
• dynatrace-webhook-yyy

Now, the Kubernetes Admin team has requested to place the mentioned pods on a dedicated node that have resource allocation for Dynatrace.

Is there a way to allocate these pods to a specific node? Such as using labels or node selectors?

Thank you.

Hi @agylpradipta,

I always use nodeSelector for this configuration in the custom resource yaml proper section.

In my case this example is used for oneagent, dynakube oneagent scheduled on the nodes which ones have worker role.

nodeSelector:

        "node-role.kubernetes.io/worker": ""

I hope it helps.

Best regards,

Mizső

Thank you for the insight.

However, have you ever tried adding nodeSelector for the webhook or dynatrace-operator?

Should it be conceptually the same?

Thank you

Hi @agylpradipta,

We had another solution for it. I have to ask the client openshift admins about it. Maybe I can come back with the answer next week after Easter.

Best regards,
