Horus

Important

This project is designed to manage my offsite setup, which is specific to my use cases, so it might not be directly useful to you. For a ready-to-use solution, please refer to my homelab project.

The name is from Horus the Child, or Harpocrates

Get started

Prerequisites

• Fork this repository because you will need to customize it for your needs.
• A credit/debit card to register for the accounts.
• Basic knowledge on Terraform, Ansible and Kubernetes (optional, but will help a lot)

Configuration files:

Terraform Cloud

• Create a Terraform Cloud account at https://app.terraform.io

Oracle Cloud

• Create an Oracle Cloud account at https://cloud.oracle.com
• Generate an API signing key:
  • Profile menu (User menu icon) -> User Settings -> API Keys -> Add API Key
  • Select Generate API Key Pair, download the private key to ~/.oci/private.pem and click Add
  • Copy the Configuration File Preview to ~/.oci/config and change key_file to ~/.oci/private.pem

If you see a warning like this, try to avoid those regions:

⚠️ Because of high demand for Arm Ampere A1 Compute capacity in the Foo and Bar regions, A1 instance availability in these regions is limited. If you plan to create A1 instances, we recommend choosing another region as your home region

Install the following packages:

• Nix

That's it! Run the following command to open the Nix shell:

nix develop

Provision

Build the infrastructure:

make
