Lesson 15 - Ingress Demo, permission denied when trying to update hosts

josepmaria

Hello,

I am following the demo on Lesson 15 and I encounter the following error when entering the command:

Ingress-demo yaml file seems to be properly configured and created:

I wonder what I am doing wrong.

So far, I have been following along the demo, and result was as expected.

Thanks in advance for your help.

Sincerely,

Josep Maria

Ps: I run kubernetes on a VM with enabled nested virtualisation, so I have been able to follow all the course labs until now. I know I diverted from the original course instructions to have Kubernetes installed in the host vm, but I did so because I experienced problems with the code when K8s was installed on my macOs.

For some reason, when using singe ' instead of '', code below was accepted.

sudo bash -c 'echo $(minikube ip) blue.io green.io >> /etc/hosts'

However, /etc/hosts file was not updated.

Therefore I resorted to updating directly the file /etc/hosts via the comand
$ nano /etc/hosts

Once oppened, I added an entry entry as per the directions on lesson 15 before the demo.

I saved the file. I opened the local browser, entered in the address bar either blue.io and green.io and displayed result was as expected.

I wonder why I could not update file /etc/hosts with the command (with either single or double comma)

$ sudo bash -c “echo $(minikube ip) blue.io green.io >> /etc/hosts” as in Lesson 15 demo.

Thank you

Hi @josepmaria,

It may have something to do with the way your terminal interprets the left vs right double quotes.
