System Initiative

This is a monolithic repository containing the System Initiative software.

About

System Initiative is the future of DevOps Automation. It is an Intuitive, Powerful, and Collaborative replacement for Infrastructure as Code.

To learn more, read our "System Initiative is the Future" blog post.

Quickstart

Follow the Local Development Setup instructions below. We are working on and investigating more way(s) to try out System Initiative in the future.

Local Development Setup

Running the System Initiative software locally can be done in a variety of ways, but this abbreviated section will focus on a single method for getting your environment ready to run the stack. For more information and options on running SI locally, see the development environment section of the docs.

(1) Choose a Supported Platform

Let's start by choosing an officially supported platform.

Platform Notes:

• On Apple Silicon systems (i.e. macOS aarch64 (arm64)), Rosetta 2 must be installed (install it with softwareupdate --install-rosetta)
• NixOS requires docker to be installed and Flakes to be enabled (see the development environment section of the docs for more information)
• Linux with MUSL instead of GNU (e.g. Alpine Linux) is untested
• Systemd may need to be enabled on WSL2

(2) Install Dependencies

Install dependencies on your chosen platform.

• 1) nix with flakes enabled version >= 2.18.1 installed
• 2) docker from Docker Desktop or Docker Engine
• 3a) direnv version >= 2.30 installed
• 3b) direnv hooked into your shell

For nix, we highly recommend using the Determinate Nix Installer.

For docker, the Docker Desktop version corresponding to your native architecture should be used. WSL2 users should be able to use either Docker Desktop for WSL2 or Docker Engine inside the WSL2 VM.

For direnv, you can install it with your package manager of choice. However, if you're unsure which installation method to use or your package manager does not provide a compatible version, you can use nix itself (e.g. nix profile install nixpkgs#direnv).

[!TIP] We recommend using the upstream docs for hooking direnv into your shell, but here is an example on how to do it on a system where zsh is the default shell. In this example, the following is added to the end of ~/.zshrc.

if [ $(command -v direnv) ]; then
   eval "$(direnv hook zsh)"
fi

(3) Enter the Repository Directory

All commands need to be run from the nix environment. Since direnv is installed and hooked into your shell, you can cd into the repository and nix will bootstrap the environment for you using the flake.

[!WARNING] You may notice a large download of dependencies when entering the repository for the first time.

(4) (Optional) Configure Docker

Docker Hub authentication is not strictly needed if you only access public docker images, but to avoid being rate-limited when qualifying images, we recommend authenticating with the docker CLI.

docker login

(5) Running the Stack

We use buck2 to run the stack, run and build individual services and libraries, perform lints and tests, etc.

Before continuing, you should stop any locally running services to avoid conflicting ports with the stack. Some of the services that will run include, but are not limited to the following: PostgreSQL, NATS, Jaeger and OpenTelemetry.

Check if you are ready to run the stack before continuing.

buck2 run dev:healthcheck

You may notice some checks related to resource limits. On macOS and in WSL2 in particular, we recommend significantly increasing the file descriptor limit for buck2 to work as intended (e.g. ulimit -n 10240).

Please note: the new file descriptor limit may not persist to future sessions.

On Linux, it may be necessary to increase the fs.inotify.max_user_watches kernel setting. If this setting is to low, you will see errors that look similar to this: Error: ENOSPC: System limit for number of file watchers reached.

Once ready, we can build relevant services and run the entire stack locally.

Please note: if you have used SI before, the following command will delete all contents of the database. Reach out to us on Discord if you have any questions.

buck2 run dev:up

Once Tilt starts, you can check on the status of all services by accessing the UI through the given port on your local host (e.g. http://localhost:10350/). Every service should eventually have a green checkmark next to them, which ensures that they are in "ready" states.

[!WARNING] Database migrations may take some time to complete.

If you would like to learn more on what's running, check out the docs. In our documentation, you can also learn more about running the stack locally and a deeper dive into system requirements.

(6) Troubleshooting in Tilt

If some services failed to start, you can restart them on the Tilt dashboard.

• A backend service fails (e.g. sdf): restart them in the following order: forklift, veritech, rebaser, pinga, sdf
• A frontend service fails (e.g. web): restart the service individually
• A dependent service fails (e.g. PostgreSQL): tear down the stack and restart

(7) Tearing Down the Stack

The following command will stop all running services and containers. It will also remove the containers and, consequentially, the data held in them.

buck2 run dev:down

Alternatively, if you wish to keep your data for later use, you can stop the containers without removing them.

buck2 run dev:stop
