When I update my kubernetes (e.g. from 1.7 to 1.8) do I need to download the new kubeconfig file? For some reason the previous one doesn't seem to work.
If using kubeadm, after re-installing or upgrading the k8s cluster, it is always good to use the updated / latest kubeconfig at /etc/kubernetes/admin.conf by doing the following so that stale / old kubeconfig is not used:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/configSteps to upgrade kubeadm from from 1.7 to 1.8 are here.
