tar and move

this step should be self explanatory.

# compress
cd /opt/k3s
tar -vzcf /opt/k3s_airgapped.tgz $(ls)

# decompress
sudo mkdir /opt/k3s
sudo tar -vzxf /opt/k3s_airgapped.tgz -C /opt/k3s

install

run as root chmod 755 k3s install.sh

cd /opt/k3s
sudo mkdir -p /var/lib/rancher/k3s/agent/images/ 
sudo mv k3s /usr/local/bin/
sudo mv k3s-airgap-images-amd64.tar /var/lib/rancher/k3s/agent/images/

#Note - not needed for Debain based systems.
yum install -y container-selinux k3s-selinux-1.4-1.el9.noarch.rpm
