Istio Sandbox - various issues: No K8s or Graphana gui or Istio namespace

[Michael Doherty]

Hi,

I'm just going through the Istio sandbox lab and there are a few issues that make me suspect I may be either doing something fundementally wrong or there is something fundementally not working.

• I cannot login into the K8s dashboard at http://10.10.20.21:8001/ui

• Or the Graphana GUI at http://10.10.20.21:8001/api/v1/proxy/namespaces/istio-system/services/grafana:3000/dashboard/db/istio-dashboard.
  
  
• When I try to inject the Istio sidecar into the bookreview I get an error stating there is no namespace for Istio (I confirm this by viewing the namespaces active on K8s master and it not there.

All the env 'seems' to be up and running OK

The K8s cluster is up OK

I am logged into the recommeded 10.10.20.21 K8s master when running the commands.

Is it that I need to initiate the actual Istion env within K8s itself so I am missing a step?

Thanks

Hi Michael,

I've noticed that 2 nodes i.e. 10.10.20.22 & 10.10.20.23 not accessible from DNS server . And then I reboot them and the provisioning script working.  It looks the lab is now tore down and no more debug can be proceeded.

Please spin up a new session and let us know if any concerns.

Thanks,

Bob

Hi all,

that worked!

In the new session everything seems to be working thus far.

Thanks
