CCIS is a service that clr-installer uses to automatically install an instance of Clear Linux. It applies role-based cloud-init configurations during the installation. It can be used to stand up a cluster of Clear Linux instances that are ready to be managed with Ansible.

To get started, simply git clone https://github.com/clearlinux/clr-cloud-init-svc.git, configure parameters.conf to suit your system, and run install.sh. This will provision a PXE server, install CCIS with default configurations, and disable NetworkManager for the internal/external interfaces set in parameters.conf which allows the systemd-networkd settings to take effect.

The default configuration for provisioning a PXE server creates a router that performs network address translation for PXE clients. Additional requirements that must be met to use the default configuration out of the box are outlined in the preparations section of the network booting documentation for Clear Linux.

CCIS relies on cloud-init configurations to perform an automated installation of Clear Linux. These need to be changed to apply user-specific configurations. Instructions on how to change these are outlined in the bulk provisioning documentation for Clear Linux.
