I have minikube running on AWS EC2 instance, installed linkerd and meshed with the application. And installed linkerd viz, when i try to view the dashboard using the command linkerd viz dashboard & gets the following error. it says socat not found, what excatly it was?

Waiting for linkerd-viz extension to become available E0705 08:55:19.417583 12977 portforward.go:400] an error occurred forwarding 38591 -> 8085: error forwarding port 8085 to pod 85909524c53355dd249637263867025b33bc1bad4e330df7ff15f3398f0e5d3d, uid : unable to do port forwarding: socat not found

CodePudding user response：

linkerd viz uses kubectl port-forward under the hood, which itself relies on the socat binary to be installed in the kubernetes host. It appears Minikube doesn't provide socat, at least in older versions. You can try a newer Minikube version, or I'd recommend instead switching to kind or k3d which is what the linkerd project uses for testing.
