Here is the documentation of how I've implemented the lab exams.

First, get your environment up and running.

My approach was to set-up a virtual machine using kubuntu-18.04 - because Kubuntu is my working environment at home.

After the first time failure with Ubuntu I've noticed that it is necessary to install

sudo apt install open-vm-tools-desktop

within the guest OS (otherwise copy and paste from host does not work). Kubuntu does not have this problem.

Turn-off swap (or the shell scripts will fail)

sudo swapoff -a

If you want to permanently deactivate swap - edit /etc/fstab so it looks similar to this - note the hash sign!

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=c3336ebf-e804-4d83-8ff2-701fa069dc68 /               ext4    errors=remount-ro 0       1
#/swapfile                                 none            swap    sw              0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

Install curl

sudo apt install curl

Install solution package from Linux Foundation (this saves a lot of time and prevents you being stuck somewhere when installing necessary packages by hand)

wget https://training.linuxfoundation.org/cm/LFD259/<some_file>.tar.xz ...

Before executing shell scripts provided by Linux Foundation make a snapshot of your VM having the OS ready and clone the VM - remember - you will need a main node and a worker node. You better have a clone of the basic setup at hand, you might need it.

find $HOME -name k8scp.sh -exec cp {} . \;
bash k8scp.sh

find $HOME -name k8sSecond.sh -exec cp {} . \;
bash k8sSecond.sh
