[xrpn]

Please run microk8s.inspect and attach the generated tarball to this issue.

We appreciate your feedback. Thank you for using microk8s.

after installing 1.14/stable the following holds:

~$ microk8s.kubectl cluster-info
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
KubeDNS 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

(note the https;// ). Available documentation shows http:// and appears not to mention what credentials to use. In /var/snap/microk8s/484/credentials there are some hints, e.g. perhaps user admin, pw admin, but

https://127.0.0.1:16443/api/v1/namespaces/kube-system/services/monitoring-grafana/proxy

trying that and other combinations from basic_auth.csv in the same directory keeps yielding

kind | "Status"
-- | --
apiVersion | "v1"
metadata | {}
status | "Failure"
message | "Unauthorized"
reason | "Unauthorized"
code | 401

The username is admin and the password can be found with microk8s.config. At the very bottom, you should see password: XXXXX

Hi @xrpn

After doing a microk8s.kubectl proxy you should be able to reach grafana from the URL you see with microk8s.kubectl cluster-info.

Available documentation shows http://

We need to do a better job with our docs. Where did you see the http:// reference?

Thanks

The tutorial at https://tutorials.ubuntu.com/tutorial/install-a-local-kubernetes-with-microk8s#4 needs to include this information, otherwise there is no way to access the pages.

The tutorial https://ubuntu.com/blog/monitoring-at-the-edge-with-microk8s states

For Grafana, the username and password will be: admin/admin.

which is just wrong and should be fixed
