Bug Description

I'm using Kind + istio to verify feature of merbridge. after apply the related logs as below:

kubectl apply -f https://raw.githubusercontent.com/merbridge/merbridge/main/deploy/all-in-one.yaml

        - /app/mbctl
        - -m
        - istio
        - --use-reconnect=true
        - --cni-mode=false

% kubectl logs merbridge-ncwvg -n istio-system

Are you running a kind cluster on a mac? This is unverified and should not be supported.
You can try testing on ubuntu.

[wdxxl]

thanks for the reply, will try using ubuntu.
does centos supported?

Yes, but maybe need upgrade kernel munally.
