Quick Start

Install the companion command-line client kraft:

# Install on macOS, Linux, and Windows:
curl -sSfL https://get.kraftkit.sh | sh

See additional installation instructions.

Run your first ultra-lightweight unikernel virtual machine:

kraft run unikraft.org/helloworld:latest

View its status and manage multiple instances:

kraft ps --all

View the community image catalog in your CLI for more apps:

kraft pkg ls --update --apps

Or browse through one of the many starter example projects.

Why Unikraft?

Unikraft is a radical, yet Linux-compatible with effortless tooling, technology for running applications as highly optimized, lightweight and single-purpose virtual machines (known as unikernels).

In today's computing landscape, efficiency is paramount. Unikraft addresses this need with its modular design, enabling developers to create customized, lightweight operating systems tailored to specific application requirements. By trimming excess overhead and minimizing attack surfaces, Unikraft enhances security and performance in cloud and edge computing environments.

Unikraft's focus on optimization ensures that applications run smoothly, leveraging platform-specific optimizations to maximize efficiency. With support for various hardware architectures and programming languages, Unikraft offers flexibility without compromising performance. In a world where resources are precious, Unikraft provides a pragmatic solution for streamlined, high-performance computing.

Getting Started

There are two ways to get started with Unikraft:

1. (Recommended) Using the companion command-line tool kraft (covered below).

2. Using the GNU Make-based system. For this, see our advanced usage guide.

Toolchain Installation

You can install the companion command-line client kraft by using the interactive installer:

# Install on macOS, Linux, and Windows:
curl -sSfL https://get.kraftkit.sh | sh

macOS

brew install unikraft/cli/kraftkit

Debian/Fedora/RHEL/Arch/Windows

Use the interactive installer or see additional installation instructions.

Codespaces

Try out one of the examples in GitHub Codespaces:

Container Build Environment

You can use the pre-built development container environment which has all dependencies necessary for building and trying out Unikraft in emulation mode.

Attach your working directory on your host as a mount path volume mapped to /workspace, e.g.:

docker run --platform linux/x86_64 -it --rm -v $(pwd):/workspace --entrypoint bash kraftkit.sh/base:latest

The above command will drop you into a container shell. Type exit or Ctrl+D to quit.

Testing your Installation

Running unikernels with kraft is designed to be simple and familiar. To test your installation of kraft, you can run the following:

kraft run unikraft.org/helloworld:latest

Build your first unikernel

Building unikernels is also designed to be straightforward. Build your first unikernel by simply placing a Kraftfile into your repo and pointing it to your existing Dockerfile:

spec: v0.6

runtime: base:latest

rootfs: ./Dockerfile

cmd: ["/path/to/my-server-app"]

Learn more about the syntax of a Kraftfile.

Once done, invoke in the context of your working directory:

kraft run .

`redis:7.2`: Connection freezes

Using Redis 7.2 (PR #43) freezes when connecting with redis-cli. Use the following commands to replicate:

wget https://raw.githubusercontent.com/unikraft/catalog-for-maintainers/main/utils/start-buildkit.sh
source start-buildkit.sh
git clone https://github.com/unikraft-upb/catalog
cd catalog
git checkout -b razvand/library/redis origin/razvand/library/redis
cd library/redis/7.2

kraft rm --all ; kraft run --log-type basic --log-level debug -M 256M -p 6379:6379 2>&1 | grep -v '\(gettimeofday\|clock_gettime\|/proc/self/stat\|epoll_wait\)'

Use redis-cli to connect to the server:

redis-cli -h localhost

The output shown will have something like this (there are two consecutive - not working redis-cli connection commands run to generate the two chunks of output):

`python:3.12`, `python:3.10`: The run command in the README.md file doesn't work.

Running the command as written in the README.md doesn't work.

kraft run -p 8080:8080 unikraft.org/python:3.12

This is because we are not providing enough memory. Adding a -M 256M flag makes it work!
