Hello all,

Here is the response as I try to inject the ingress controller

~/ingress-nginx$ ingress-nginx$ kubectl get ds myingress-ingress-nginx-controller -o yaml | linkerd inject --ingress - | kubectl apply -f -
ingress-nginx$: command not found

‼ no supported objects found

Any hints on what may be the cause?

    Hi @nicocerquera,

    It seems you copy/pasted both the prompt and command.

    Regards,

    Now I am having some trouble with the visualization of the web page, what app or command can I use to see that visualization of linkerd?

    Hi @nicocerquera,

    The sequence of commands is in the lab guide. Did you see any errors while running them? Did you configure the web deployment and web service as described by steps 2 and 3?

    With all preliminary steps completed, you can open the console in the browser with the public IP of the node (step 4) and the NodePort of the web service (which is set to 31500 in step 3).

    Regards,
    -Chris

    I noticed that the system stays in this loop

    I tried to go back to 11.1 and make sure steps 2 and 3 where correct and then I noticed what appears to be a racing state ^

    looks like it is working but I can not access the dashboard externally:

    ncerquera@dev-node128:~$ curl http://localhost:50750

    Hi @nicocerquera,

    Have you tried following the instructions from the lab guide? Step 5 mentions the following:

    From you local system open a browser and go to the public IP and the high-number nodePort

    What was the outcome?

    Regards,
    -Chris
