Microk8s: How to use Helm 3

[magick93]

Description

I'm unable to use Helm3.

When I try the following:

1. microk8s enable helm3
2. helm list

I get Error: Kubernetes cluster unreachable.

I then try:

1. microk8s.config view > /home/anton/.kube/config as suggested in https://github.com/ubuntu/microk8s/issues/833
2. helm list

And get the same

Doesnt Work

kubectl cluster-info

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
Unable to connect to the server: x509: certificate signed by unknown authority

Works

kubectl cluster-info --insecure-skip-tls-verify=true

Kubernetes master is running at https://127.0.0.1:16443
Heapster is running at https://127.0.0.1:16443/api/v1/namespaces/kube-system/services/heapster/proxy
CoreDNS is running at https://127.0.0.1:16443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
Grafana is running at https://127.0.0.1:16443/api/v1/namespaces/kube-system/services/monitoring-grafana/proxy
InfluxDB is running at https://127.0.0.1:16443/api/v1/namespaces/kube-system/services/monitoring-influxdb:http/proxy

So I assume the issue is something to do with certificates, however, from my understanding Helm3 doesnt use Tiller.

I believe you could have used the addon comming with MicroK8s (microk8s enable helm3) and then use microk8s helm3.
