Nua

What is Nua?

Vision

Nua is an open source, self-hosted cloud platform project (a PaaS - platform as a service).

Nua streamlines the development, selection, installation and resilient operation of web applications in a self-hosted cloud environment.

It is primarily aimed at users (SMEs, associations, public services, etc.) who wish to benefit from the simplicity of the cloud at the lowest cost without compromising the principles of digital sovereignty.

Its watchwords are: simplicity, resilience and equity.

Hacking on Nua

Technical Architecture

Subpackages

The Nua project is a monorepo, split into several subpackages:

• nua-lib: common code for all Nua packages (details).
• nua-cli: command-line interface for Nua (details).
• nua-agent: agent for Nua apps (details).
• nua-build: build system for Nua packages (details).
• nua-orchestrator: orchestrator for Nua applications (details).
• nua-server: web UI for a Nua iserver (details). Not ready yet.

It also comprises several example applications, as well as a few real-world applications: apps.

To install a development environment, you will need Poetry, and to run:

poetry install

You also need a Docker server.

Roadmap and current status

The roadmap for the projet is kept up to date on this kanban board.

See also: TODO.md and HISTORY.md.

As of 2023/04/29, we have the following components:

• The "builder" CLI that can build container images from high level specifications (nua-config.tom files).
• The "orchestrator" CLI that can deploy and manage container images.
• The nua CLI that provides a unified interface to the builder and orchestrator.
• We have started packaging some applications (HedgeDoc, Dolibarr, Galene, Dolibarr, Etherpad-lite).
