Enable Istio in fission

Question

I have a Kubernetes (v1.10) cluster with Istio installed, I'm trying to install fission following Enabling Istio on Fission guide. when i run

[![helm install --namespace $FISSION_NAMESPACE --set enableIstio=true --name istio-demo 
https://github.com/fission/fission/releases/download/0.9.1/fission-all-0.9.1.tgz

It throws error saying

Error: the server has asked for the client to provide credentials

(My cluster has two nodes and one master created using kubespray all ubuntu 16.04 machines)

Answer 1

I think that error is probably an authentication failure between helm and the cluster. Are you able to run kubectl version? How about helm ls?

If you have follow up questions, could you ask them on the fission slack? You'll get quicker answers there.

Answer 2

I think problem with helm

Solution

Remove .helm folder

rm -rf .helm

kubectl create serviceaccount tiller --namespace kube-system

kubectl create clusterrolebinding tiller-cluster-rule \
 --clusterrole=cluster-admin \
 --serviceaccount=kube-system:tiller

helm init --service-account=tiller

kubectl get pods -n kube-system
