Core Features

Secure Execution

Isolated environment execution using WebAssembly sandboxing for containerized workloads.

Minimal Footprint

Reduced attack surface with modular microkernel architecture and strict dependency management.

Cloud-Optimized

Optimized for container orchestration systems including Kubernetes and other cloud environments.

Quick Start

CloudOS requires Rust (1.55+), WebAssembly, and Docker for local development. 

cargo install --force wasm-pack
git clone https://github.com/opensource/cloudos.git
cd cloudos

# Build the kernel module
cargo build --target wasm32-wasi --release
wasm-pack build --target web --out-dir ./dist

Running CloudOS

Use Docker to spin up the CloudOS container with WebAssembly support. 

docker run -it --name cloudos \
    -v $(pwd):/app \
    opensource/cloudos:latest
