SSH Access The password will be provided by the trainer: ssh k8s@ Kubernetes Access The kubeconfig file allows connection to the Kubernetes server. # Retrieve the k8s cluster authentication file mkdir -p ~/.kube cp /tmp/config $HOME/.kube/config chmod 600 $HOME/.kube/config # Alternate solution, kind specific kind export kubeconfig # Launch k8s-toolbox interactively ktbx desk # Check Kubernetes status kubectl cluster-info # Check node status kubectl get nodes # Create a namespace kubectl create namespace # Change the current context's active namespace kubens # Create a pod # use "kubectl run --help" to retrieve the correct command kubectl run ??? # Add a label to the pod kubectl label 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 oc new-project --help # Check you context again kubectx # Switch to other context/cluster # kubectx default/api-crc-testing:6443/kubeadmin Download the Labs Once in the toolbox, run one of the commands below to download the labs:

Setting Up the Training Platform

Wed, 22 May 2024 14:15:26 +1000

During the training, it is recommended to use the provided platform. This section describes how to reproduce it after the training to replay the labs. Prerequisites Local Machine Configuration Fedora is recommended 8 cores, 16 GB of RAM, 30 GB for the partition hosting Docker entities (images, volumes, containers, etc). Use the df command as shown below to find its size. sudo df -sh /var/lib/docker # or /var/snap/docker/common/var-lib-docker/ Internet access without proxy sudo access Install the dependencies below: sudo dnf install curl docker git vim bash-completion # then add the current user to the docker group sudo usermod -a -G docker $USER # or restart the gnome session newgrp docker Then, you can create the Kubernetes cluster in two lines by following the ktbx documentation.
