This is a Docker (version 17.06+) container for automatically building minimal rolling CentOS 7 ISO images with unattended installation routines.
Currently it includes open-vm-tools, injects an RSA public key, enables DHCP & SSH w/ passwordless sudo and installs to /dev/sda.
The goal is to provide an ideal image for rapidly deploying Kubernetes using a tool like MetalK8s which can then use Ansible to take care of the rest.
Coaster can be invoked like this:
./run
The resulting ISO is created in the output directory
This early version is not very modular and does not have much error handling, but you can modify the included kickstart to suit your needs.
