Installing the Binary¶

You can use various package managers to install the nsv binary. Take your pick.

Package Managers¶

Apt¶

To install using the apt package manager:

echo 'deb [trusted=yes] https://fury.purpleclay.dev/apt/ /' \
  | sudo tee /etc/apt/sources.list.d/purpleclay.list
sudo apt update
sudo apt install -y nsv

You may need to install the ca-certificates package if you encounter trust issues with regard to the Gemfury certificate:

sudo apt update && sudo apt install -y ca-certificates

Pacman (ALPM)¶

nsv is available as a package on the AUR. You can install it using an AUR helper (e.g. yay):

yay -S nsv

Homebrew¶

To use Homebrew:

brew install purpleclay/tap/nsv

Nix Flake¶

To use Nix Flakes (highlights illustrate flake changes):

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";

    nsv = {
      url = "github:purpleclay/nsv-nix";
      inputs = {
        nixpkgs.follows = "nixpkgs";
      };
    };
  };

  outputs = { self, nixpkgs, flake-utils, nsv }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};
      in
      with pkgs;
      {
        devShells.default = mkShell {
          buildInputs = [
            nsv.packages.${system}.nsv
          ];
        };
      }
    );
}

Yum¶

To install using the yum package manager:

echo '[purpleclay]
name=purpleclay
baseurl=https://fury.purpleclay.dev/yum/
enabled=1
gpgcheck=0' | sudo tee /etc/yum.repos.d/purpleclay.repo
sudo yum install -y nsv

Linux Packages¶

Download and manually install one of the .deb, .rpm or .apk packages from the Releases page.

AptYumApk

sudo apt install nsv_*.deb

sudo yum localinstall nsv_*.rpm

sudo apk add --no-cache --allow-untrusted nsv_*.apk

Go Install¶

go install github.com/purpleclay/nsv@latest

Bash Script¶

To install the latest version using a script:

sh -c "$(curl https://raw.githubusercontent.com/purpleclay/nsv/main/scripts/install.sh)"

Download a specific version using the -v flag. The script uses sudo by default but can be disabled through the --no-sudo flag. You can also provide a different installation directory from the default /usr/local/bin by using the -d flag:

sh -c "$(curl https://raw.githubusercontent.com/purpleclay/nsv/main/scripts/install.sh)" \
  -- -v v0.3.0 --no-sudo -d ./bin

Manual download of binary¶

Head over to the Releases page on GitHub and download any release artefact. Unpack the nsv binary and add it to your PATH.

Verifying a binary with cosign¶

All binaries can be verified using the checksum file and cosign.

Download the checksum file:

curl -sL https://github.com/purpleclay/nsv/releases/download/v0.10.1/checksums.txt -O

Verify the signature of the file:

cosign verify-blob \
  --certificate-identity 'https://github.com/purpleclay/nsv/.github/workflows/release.yml@refs/tags/v0.10.1' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --cert 'https://github.com/purpleclay/nsv/releases/download/v0.10.1/checksums.txt.pem' \
  --signature 'https://github.com/purpleclay/nsv/releases/download/v0.10.1/checksums.txt.sig' \
  checksums.txt

Download any release artifact and verify its SHA256 signature matches the entry within the checksum file:

sha256sum --ignore-missing -c checksums.txt
