Kubernetes : dial tcp 127.0.0.1:8080: connect: connection refused
Kubernetes uses a $KUBECONFIG file for connecting to clusters. It may be when provisioning your kops cluster, it didn't write the file correctly. I can't be sure as you haven't provided enough info.
Assuming this is the issue, and you only have a single cluster, it can be resolved like so:
# Find your cluster namekops get clusters# set the clustername as a varclustername=<clustername># export the KUBECONFIG variable, which kubectl uses to find the kubeconfig fileexport KUBECONFIG=~/.kube/${clustername}# download the kubeconfig file locally using kopskops export kubecfg --name ${clustername} --config=~$KUBECONFIGYou can find more information about the KUBECONFIG file here
you have to start minikube before using kubectlI had the same issue but mine was because minikube was not running
