Can we have short guide on how we can integrate our own cluster with the exam suite?
There is not much documentation.

We want to add support for (kind)[https://github.com/kubernetes-sigs/kind] so that the whole setup has its own infra to work on and the overall scenario can be as close and similar to what is presented in the exam.

The timer gets reset once the page is refreshed which should not happen, and this needs to be fixed.

Reprod this on Windows and Ubuntu:

Thanks for the tool. I tried starting the lab using docker-compose up -d, but when I open the website, I get Authentication Failure

Steps to reproduce

1. Start minikube and point kubectl on it.
2. start docker engine

docker-machine start default
eval $(docker-machine env default)

2. parse docker host IP IP=$(docker-machine ip default)

3. Run app docker-compose up -d

4. Visit http://${IP}

5. Click "Let's Start Exam"

Issue

Authentication failure.

• Do I need browser plugin?
• Do I need CKA candidate handbook to understand what's error in this simulation?

HI when I'm trying to run kubectl get node in browser getting this error
The connection to the server 127.0.0.1:6443 was refused - did you specify the right host or port?

Following the README it was simple to get up and running at http://localhost (on Mac OS 10.15.7)

But I can't get passed the first question :-)

I ran the following commands:

apt-get update

sudo is missing so I install it

apt-get install sudo

These commands come from https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/

sudo apt-get update && sudo apt-get install -y apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
cat <<EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list
deb https://apt.kubernetes.io/ kubernetes-xenial main
EOF
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
sudo apt-mark hold kubelet kubeadm kubectl

But when I run "kubeadm init" I get the following error:
W1107 15:30:50.563919 1034 kubelet.go:200] cannot automatically set CgroupDriver when starting the Kubelet: cannot execute 'docker info -f {{.CgroupDriver}}':
executable file not found in $PATH

Basically the "docker" command is not found.

I've tried installing docker, but I get errors when trying to start it.

In the 1st question : "Bootstrap a Kubernetes v1.10 cluster using kubeadm", it seems that kubeadm is not installed and even docker daemon is not running in the SSH Terminal : is it normal ?
Do we need to install all the needed tools manually in the web app console before taking the test ?

hi
run command: docker-compose up -d

ERROR: Service 'gateone' failed to build: Get https://registry-1.docker.io/v2/arush/gateone/manifests/latest: unauthorized: incorrect username or password

The following question contains a dead link :

Q. Enable cluster auditing
Enable cluster wide auditing. You can use the audit policy provide at here.
Make sure the audit logs are properly generated and saved to a log file.

Hi,

I really enjoy the tool and think its a great way to study for the CKA.

However, I would like to suggest you also supply the answers too. For those of us studying for the cert, the answers may not be what we think. It would be nice have a way to verify that.

Thanks

I can't see any of the exercises, is this expected?
