linkerd-proxy can't start on few pods

[garimakhulbe02]

I am trying to install Linkerd 2.8.1 on AKS cluster and getting this error.

linkerd-api
-----------
× control plane pods are ready
    pod/linkerd-prometheus-554cb7f647-w4gjx container linkerd-proxy is not ready
    see https://linkerd.io/checks/#l5d-api-control-ready for hints

kubectl get pod -n linkerd

I can see following errors on these pods...

kubectl logs linkerd-prometheus-554cb7f647-w4gjx -n linkerd -c linkerd-proxy

I am trying to install linkerd on AKS cluster which does not have any app running yet. It seemed like linkerd-proxy container is taking longer in getting ready so I added wait time in ```check``. However error still persists.

$LINKERD_BIN check --pre | \
    $LINKERD_BIN install | kubectl apply -f - && \
    $LINKERD_BIN check --wait 15m0s

AKS version: 1.17.7
Linkerd: 2.8.1

There is not much resources on this online. Have anyone seen this error?

Hard to tell what's going on with your cluster. Are there enough cpu/memory resources?
