Installation

This guide shows how to install cunīcu. cunīcu can be installed either from source, or from pre-built binary releases.

From the Binary Releases

Every release of cunīcu provides binary releases for a variety of OSes. These binary versions can be manually downloaded and installed.

By Hand

1. Download your desired version
2. Unzip it: gunzip cunicu_0.0.1_linux_amd64.tar.gz
3. Move the unzipped binary to its desired destination: mv cunicu /usr/local/bin/cunicu
4. Make it executable: chmod +x /usr/local/bin/cunicu
5. From there, you should be able to run the client and add the stable repo: cunicu help.

note

cunīcu automated tests are performed for Linux, macOS and Windows on x86_64, ARMv6, ARMv8 amd ARM64 architectures. Testing of other OSes are the responsibility of the community requesting cunīcu for the OS in question.

From Script

cunīcu also has an installer script that will automatically grab the latest version of cunīcu and install it locally.

You can fetch that script, and then execute it locally. It's well documented so that you can read through it and understand what it is doing before you run it.

curl -fsSL -o get_cunicu.sh get.cunicu.li
chmod 700 get_cunicu.sh
./get_cunicu.sh

Yes, you can curl -fsSL get.cunicu.li | bash if you want to live on the edge.

echo "deb [arch=$(dpkg --print-architecture) trusted=yes] https://packages.cunicu.li/apt/ /" | sudo tee /etc/apt/sources.list.d/cunicu.list
sudo apt-get update
sudo apt-get install cunicu

Flakes

Building and installing cunīcu via Nix is possible with flakes:

nix profile install github:cunicu/cunicu/nix?dir=nix

Legacy

You can also use nix-env/nix-build if you have cunicu checked out locally.

# check out cunicu
git clone https://github.com/cunicu/cunicu --branch nix && cd cunicu

# Build cunicu and add it to the environment
nix-env -if ./nix

From Source (all)

Building cunīcu is fairly easy and allows you to install the latest unreleased version.

You must have a working Go environment.

go install github.com/cunicu/cunicu/cmd/cunicu@latest

If required, it will fetch the dependencies and cache them, and validate configuration. It will then compile cunīcu and place it in ${GOPATH}/bin/cunicu.

Conclusion

In most cases, installation is as simple as getting a pre-built cunīcu binary. This document covers additional cases for those who want to do more sophisticated things with cunīcu.

Once you have cunīcu successfully installed, you can move on to using cunīcu to setup your mesh VPN network.
