Access to Labs

SSH Access

The password will be provided by the trainer:

ssh student<ID>@<serverip>

The kubeadm lab: your own two nodes

The kubeadm lab builds a Kubernetes cluster from scratch, so it needs real machines rather than the shared kind cluster. Two are provisioned for you:

Host	Role
`student<ID>-1`	master (control plane)
`student<ID>-2`	worker

Reach them from the training server — no password, no key to install:

ssh student3-1     # logged in as student3; or simply: ssh "$USER-1"

Kubernetes Access

Retrieve the kubeconfig for the shared kind cluster:

kind export kubeconfig

# Check Kubernetes status
kubectl cluster-info

# Check node status
kubectl get nodes

# Create a namespace
kubectl create namespace <ID-first-name>

# Change the current context's active namespace
kubens <ID-first-name>

# Create a pod
# use "kubectl run --help" to retrieve the correct command
kubectl run <your-pod> ???

# Add a label to the pod
kubectl label pod <your-pod> tutorial=true

Openshift Access

# inside the toolbox
# Retrieve password in /tmp/oc-creds.txt
oc login -u kubeadmin https://api.crc.testing:6443

# Watch the cluster
kubectl get nodes

# Check you context
kubectx

# Create a namespace <ID-first-name>
oc new-project --help

# Check you context again
kubectx

# Switch to other context/cluster
# kubectx default/api-crc-testing:6443/kubeadmin
