Running on Mac

[jblackburn21]

Hi,

I was able to get the example running on mac using PR #3, but I'm seeing a failure on the link step.

the linkerd mc check command returns this

x remote cluster access credentials are valid
            * failed to connect to API for cluster: [west]: Get "https://172.18.0.6:6443/version?timeout=30s": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
    see https://linkerd.io/checks/#l5d-smc-target-clusters-access for hints
W0511 09:19:44.728000   75418 transport.go:260] Unable to cancel request for promhttp.RoundTripperFunc

x clusters share trust anchors
    Problematic clusters:
    * west: unable to fetch anchors: Get "https://172.18.0.6:6443/api/v1/namespaces/linkerd/configmaps/linkerd-config?timeout=30s": context deadline exceeded
    see https://linkerd.io/checks/#l5d-multicluster-clusters-share-anchors for hints

I see this in the service-mirror logs

time="2021-05-11T15:17:40Z" level=info msg="Received: RepairEndpoints" apiAddress="https://172.18.0.6:6443" cluster=remote
time="2021-05-11T15:17:43Z" level=warning msg="Gateway returned unexpected status 503. Marking as unhealthy" probe-key=west

I'm able to curl between the clusters, so I'm not sure why there is a timeout. Do you have any ideas on what could be causing this?

Got same error on macOS after link:

Status check results are ×

However, the demo can still run well.
