scaf provides developers and DevOps engineers with a complete blueprint for a new project and streamlines the development experience with Tilt.

scaf generates a new project structure with Kubernetes manifests in three Kustomize layers for dev, sandbox, and production. A new project contains the following:

• NextJS or React frontend
• Django backend
• Postgres database for local development
• CloudNativePG deployment for production
• Redis
• Mailhog
• ArgoCD
• Traefik
• Certmanger
• Certificates and Ingress Routes
• Kube Prometheus Stack
• Grafana Loki
• GitHub and Bitbucket pipelines to build and push images, run security, formatting and linting checks
• Terraform config to set up a k3s cluster on AWS

Installation

Installation is supported on Linux and macOS:

curl -sSL https://raw.githubusercontent.com/sixfeetup/scaf/main/install.sh | sh

The installation script will install kubectl, kind, and Tilt if it can't be found on your system.

Creating a new project using this repo

Run scaf myproject, answer all the questions, and you'll have your new project!

Inside myproject/README.md, you will have more documentation explaining how to use and configure your newly created project.

Terraform and AWS

To deploy your project using Terraform and AWS, you can follow the instructions in terraform/README.md.
Note that you will need:

• an AWS account where you have access to the OrganizationAccountAccessRole
• terraform, and AWS CLI installed and configured

Development on Scaf

Nix Flake

Scaf provides a Nix Flake to install all the required packages for development. The Nix Flake ensures all developers are using the same versions of all packages to develop on Scaf in an isolated environment.

Follow the instructions to install Nix for your OS.

Nix Flakes are a feature that comes with Nix, but they are considered experimental and are not enabled by default in stable releases of Nix. To use Nix Flakes, you need to enable them by configuring your Nix installation to allow experimental features.

1. Ensure you have a recent version of Nix installed:

Nix Flakes are available in recent versions of Nix. You can check your Nix version using:

nix --version

If you need to install or update Nix, you can follow the instructions on the Nix installation page.

2. Enable experimental features:

You need to enable the experimental features in your Nix configuration. To do this, add the following lines to your ~/.config/nix/nix.conf file. If the file doesn't exist, you can create it:

experimental-features = nix-command flakes

3. Using Nix Flakes:

Once you have enabled the experimental features, you can use Nix Flakes with the nix command. For example:

nix flake show

This command will display information about the flake in the current directory if you have a flake.nix file.

Finally, install Direnv and run direnv allow. The direnv configuration in .envrc will use the flake to install the required packages.

Django version updates

When making changes to scaf, keep the following in mind:

• update pins in requirements/*.in files but *don't* commit the compiled requirements.txt files to the repo.
• update to the latest Python supported by Django. For Django 4.1, this is 3.8, 3.9, and 3.10.
