This is a rough shopping list of skills/accounts that will be a benefit for this guide.

• Equinix Metal portal account
• GO experience (basic)
• iptables usage (basic)
• qemu usage (basic)

# Create Tinkerbell bridge
sudo ip link add tinkerbell type bridge
#
# Assign Address to bridge
sudo ip addr add 192.168.1.1/24 dev tinkerbell

# Create tap
sudo ip tuntap add dev tinkGuest mode tap user $USER
#
# Add to bridge

The Architecture

Below is a sample architecture, no workers for this example :-)

• VIP 192.168.0.40
• K8S01 192.168.0.41
• K8S02 192.168.0.42
• DB01 192.168.0.43

Create our DB on DB01
