Failing to pull image grafana/grafana:7.5.5

[mlamia-usa]

I am attempting to install Grafana in my AKS-HCI environment per the instructions in Grafana.md. I first installed the monitoring on my target cluster using Install-AksHciMonitoring. I receive the following error:

Warning Failed 83s kubelet Failed to pull image "grafana/grafana:7.5.5": rpc error: code = Unknown desc = failed to pull and unpack image "docker.io/grafana/grafana:7.5.5": failed to copy: httpReaderSeeker: failed open: unexpected status code https://registry-.docker.io/v2/grafana/grafana/manifests/sha256:075819791b43f30aab18497fff217d3aec918d7d55bf873818de6a916da04d54: 429

Too Many Requests - Server message: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

My understanding is that I may have to follow the instructions in the 'Deploy an image from ACR to AKS on Azure Stack HCI' section in the following site: https://docs.microsoft.com/en-us/azure-stack/aks-hci/deploy-azure-container-registry. Could you please confirm.

Information about my deployment:

AKS-HCI service host version: 1.0.4.10928
Kubernetes version for service host and target cluster: 1.20.7
Azure Stack HCI OS, version 20H2
