create tftp environment to boot and perform installation over network (now: Desktop from server image)

tftp-ubuntu-installation

a complete netboot-server-rollout for deploying ubuntu installations over pxe

Prerequisites:

• running dnsmasq as docker instance using ferrarimarco/pxe; refer configs/dnsmasq/pxe.conf for configuration your custom config in /etc/dnsmasq.d/yourconf.conf
• running http server pointing to the http-folder, or it's symbolic link; I'm using a goStatic docker container for this. A compose sample is placed in configs/compose/
• if you have a lot of deployments, it's recommended to use a cached proxy like nesus3 like this repo. Peek into compose.yml for a docker deployment. The nexus-setup ist documented in configs/nexus-config.yaml

Recommendations:

• link via ln -s the folders http and tftp to your favourite server folders
• be aware of struggling with existing DHCP-servers and dnsmasq in the same network. This is not a part of this topic: simply search online for this. Just run getRequirements.sh to fullify all required structures and files to make a netboot for ubuntu jammy happen.

Run tftp/getRequirements.sh to fullyfy all directories and files from it's folder after initial clone

Example target directory structures:
