WORK IN PROGRESS

Hardware

• 4 nodes of NEC SFF PC (Japanese version of the ThinkCentre M700)
  • CPU: Intel Core i5-6600T
  • RAM: 16GB
  • SSD: 128GB
• TP-Link TL-SG108 switch

Architecture

Layer	Name	Description	Provisioner
0	metal	Bare metal OS installation, LXD, Terraform state backend,...	Ansible, PXE server
1	infra	Kubernetes clusters	Terraform
2	platform	Vault, Git, Argo,...	Helm
3	apps		Argo

Usage

Prerequisite

For the controller (to run Ansible, stateless PXE server, Terraform...):

• SSH keys in ~/.ssh/{id_rsa,id_rsa.pub}
• make
• python3
• Docker with host networking driver (which means only Docker on Linux hosts)
• terraform (0.14.x)
• multipass (optional, to create a test environment locally)

For bare metal nodes:

• PXE IPv4 enabled
• Wake-on-LAN enabled
• Secure boot disabled (optional, depending on the OS)

Configurations

• Bare metal nodes settings (IP, MAC...)
• OS settings (PXE, network...)

Building

Simply run:

make

Or we can build each layer individually:

make infra
# or
cd infra
make
