Web UI not working
Sometimes flannel, the overlay network between the pods, does not work properly when first booted. This can cause the Web UI to not work.
You can fix this by either:
- Deleting all flannel pods. Kubernetes will create new ones.
kubectl -n kube-system delete pod -l app=flannel
Restarting flannel on the affected node. Find the node running dashboard, you might want to
Node:if the output is too verbose.
kubectl -n kube-system describe pod -l k8s-app=kubernetes-dashboard
kubectl describeon each of the flannel pods until you find the one that is running on the same node.
Delete that pod. Kubernetes will create a new one in its place.
