Merge multiple ~/.kube/config into one using kubectl konfig merge
1) Make a backup of your current ~/.kube/config
cp ~/.kube/config ~/.kube/config.BAK.$(date '+%Y-%m-%d_%H%M')
2) Use kubectl konfig merge for merge files:
kubectl konfig merge ~/.kube/config yournewcluster-configfile > merged_kubeconfig
3) Overwrite your old ~/.kube/config with your new file
cp merged_kubeconfig ~/.kube/config
for CLUSTER in $(rancher cluster ls | grep -v NAME | cut -d"*" -f2- | awk '{print $3}' ); do rancher cluster kubeconfig $CLUSTER > $CLUSTER.kubeconfig; done
