We would like to get familiar with the tools.

On the left you can press Start "START LESSON".

This opens a black panel on the right which should display "Warming up playground...". A Kubernetes Cluster is bootstrapped in the back which (just for you), the so-called Playground. Indeed it's virutal machines running on the infrastructure which present you with a Terminal.

Tabs of the lab environment.

This Playground provides you a terminal on the dev-machine and on the Kubernetes Nodes node-01.

On the dev-machine the frontends for kubectl and docker are installed. This means we could create a Docker container using docker run.

docker run -ti alpine sh
/ # ps faux
PID   USER     TIME  COMMAND
    1 root      0:00 sh
   10 root      0:00 ps faux
/ # exit

We can also start a pod on Kubernetes using kubectl.

kubectl apply -f - <<EOF
apiVersion: v1
kind: Pod
metadata:
  name: my-pod
  labels:
    app: web
spec:
  containers:
    - name: nginx
      image: nginx:1.27
      ports:
        - containerPort: 80
EOF

The pod should now be running on one of the Nodes:

kubectl get pods
NAME     READY   STATUS    RESTARTS   AGE
my-pod   1/1     Running   0          11s

We can even expose the ports:

docker run -ti -d -p 80:80 nginx

On the top-right is the "dots menu", which provides "Expose HTTP port" or you click open HTTP on dev-machineCopy URL.

You're set! In the training we will run attacks and break containers.
