Install Kubernetes Dynatrace Operator Error

MMM_01 — Mon, 15 Dec 2025 07:20:08 GMT

I am facing an issue when trying to install Dynatrace Operator by Script:

helm install Dynatrace-operator oci://publick.ecr.aws/Dynatrace-operator --create-namespace --namespace dynatrace --atomic

following error received:

Error: INSTALLATION FAILED: GET https://public.ecr.aws/v2/dynatrace/dynatrace-operator/tags/list: unable to retrieve credential.

Which credential is required & how to proceed with installation

Thank you

You have typos (capital letters and incorrect domain name) in the helm command, it should be:
helm install dynatrace-operator oci://public.ecr.aws/dynatrace/dynatrace-operator --create-namespace --namespace dynatrace --atomic

However, this does not explain the error. Do you use http proxy in your environment and is the cluster allowed to pull images from Internet (public.ecr.aws repository)?

As mentioned above - Try following these steps instead.

Use a public registry — Dynatrace Docs
Use a private registry — Dynatrace Docs

They should resolve your issue. the above error is indicating that you have not passed the required registry credentials for accessing the image - this can happen if you are behind proxy.

Also, you can pass the no-proxy flag in your command which will prevent this as well.

Thanks Loman,

Yes, there is a proxy in the environment.

Thanks gopher.

How to pass the no-proxy flag in the command?

@MMM_01 these are passed In your CRD

DynaKube feature flags for Dynatrace Operator — Dynatrace Docs

Where using a private registry, you need to pass the registry dns name in the no-proxy to disable asking credentials.

Example below,

apiVersion: ${API_VERSION} kind: DynaKube metadata: name: dynakube namespace: dynatrace annotations: feature.dynatrace.com/no-proxy: "${NO_PROXY}" #private repo
