Spawn CLI Documentation

The Spawn CLI is a powerful command-line tool designed to simplify the management and development of Spawn projects and infrastructure. This guide provides an overview of the available commands, their subcommands, and usage examples.

Commands Overview

  • new: Create new Spawn projects targeting a specific programming language.

  • apply: Deploy actor resources to a Kubernetes cluster.

  • config: Configure Spawn applications, such as ActorSystem and ActorHost CRDs.

  • dev: Manage local development workflows.

  • install: Install orchestrators or runtimes, such as Kubernetes.

  • playground: Set up and run a complete Spawn tutorial.

Each command comes with its own set of options and subcommands, which are detailed below.
