Linux下Minikube v0.34.1启动报错：k8s-app=kube-proxy连接被拒绝

Hey Eric, awesome that you got this issue sorted out! For anyone else running into the same connection refused error with kube-proxy when using Minikube v0.34.1 on Linux—even after trying minikube delete and wiping the ~/.minikube directory—here's the solution that fixed it:

Step 1: Perform a full deep cleanup of Minikube resources #

The standard minikube delete command might leave behind residual network interfaces or virtual machine artifacts that cause conflicts. Run these commands to wipe all Minikube and Kubernetes-related data completely:

minikube delete --all --purge
sudo rm -rf ~/.minikube ~/.kube
sudo ip link delete minikube0  # Removes the Minikube-specific network interface

Step 2: Start Minikube with an explicitly compatible Kubernetes version #

Minikube v0.34.1 has known compatibility quirks with the default newer Kubernetes versions it tries to pull. Specifying a tested, compatible version resolves the kube-proxy connection refusal issue:

minikube start --logtostderr --kubernetes-version=v1.14.0

Step 3: Verify the fix #

Once Minikube finishes starting, confirm that the kube-proxy pod is running correctly with this command:

kubectl get pods -n kube-system -l k8s-app=kube-proxy

You should see the pod in a Running state, and the original connection error will no longer appear.

A quick additional check: make sure your Linux system has virtualization enabled (run egrep -c '(vmx|svm)' /proc/cpuinfo—if the output is greater than 0, virtualization is active). If you suspect firewall interference, temporarily disable it to rule out port blocking on 8443 for the Minikube VM IP.
