Basic setup fails to inject linkerd proxy into services

[hmih]

Hello!

I am having an issue with the latest Linkerd (I haved tried 2.13.3 and edge). I am just setting it up in the most basic way. I am on a macos with docker for desktop. All the validation checks pass. No containers are injected and the setup seems broken. Here are the commands I am running:

        cmds = [
            # uninstall existing
            "linkerd uninstall | kubectl delete -f -",
            # validation
            "linkerd check --pre",
            # install with crds
            "linkerd install --crds | kubectl apply -f -",
            # real installation
            "linkerd install \
                --set proxyInit.runAsRoot=true \
                | kubectl apply -f -",
            # validation
            f"linkerd check && linkerd check -n {env}",
            # tag namespace
            f"kubectl get -n {env} deploy -o yaml | linkerd inject - | kubectl apply -f -",
        ]

My dev namespace is tagged with the annotation to inject linkerd proxies. However, no proxies appear. When I log the linkerd pods I see:

In the pod-injector:
[     0.042122s]  WARN ThreadId(01) dst:controller{addr=linkerd-dst-headless.linkerd.svc.cluster.local:8086}: linkerd_app_core::control: Failed to resolve control-plane component error=failed SRV and A record lookups: failed to resolve SRV record: no record found for Query { name: Name("linkerd-dst-headless.linkerd.svc.cluster.local."), query_type: SRV, query_class: IN }; failed to resolve A record: no record found for Query { name: Name("linkerd-dst-headless.linkerd.svc.cluster.local."), query_type: AAAA, query_class: IN } error.sources=[failed to resolve A record: no record found for Query { name: Name("linkerd-dst-headless.linkerd.svc.cluster.local."), query_type: AAAA, query_class: IN }, no record found for Query { name: Name("linkerd-dst-headless.linkerd.svc.cluster.local."), query_type: AAAA, query_class: IN }]

And in the linkerd-destination very many:

 Failed to connect error=endpoint 127.0.0.1:8090: Connection refused (os error 111) error.sources=[Connection refused (os error 111)]
[    39.413226s]  WARN ThreadId(01) watch{port=9996}:controller{addr=localhost:8090}:endpoint{addr=127.0.0.1:8090}: linkerd_reconnect: Failed to connect error=endpoint 127.0.0.1:8090: Connection refused (os error 111) error.sources=[Connection refused (os error 111)]
[    39.567662s]  INFO ThreadId(02) daemon:identity: linkerd_app: Certified identity id=linkerd-destination.linkerd.serviceaccount.identity.linkerd.cluster.local

The identity service looks fine. Any idea how I can proceed?

I figured out my issue. I had a LimitRange for memory that was being overrun. After changing it the proxies are injected!
