How to Install Tsuru on nixOS Latest

Tsuru is an open-source platform as a service (PaaS) that enables developers to easily deploy and manage applications on cloud infrastructure. In this tutorial, you will learn how to install Tsuru on the latest version of nixOS.

Prerequisites

Before installing Tsuru, you must have:

• A machine running nixOS latest.
• Access to the root user or a user with sudo privileges.
• An internet connection.

Step 1: Update the System

Before installing any new software on your system, it is always a good practice to update the system package repositories and packages to the latest version. To update the system, run the following command:

sudo nix-channel --update
sudo nixos-rebuild switch

Step 2: Install Tsuru Dependencies

The first step of installing Tsuru is to install its dependencies. Tsuru requires the following dependencies:

• MongoDB - a NoSQL document-oriented database
• Git - a version control system
• Go - a programming language
• Python - a programming language
• Redis - an in-memory data structure store

To install these dependencies on nixOS, you need to modify the configuration.nix file located in the /etc/nixos directory. In this file, you need to add the following lines:

environment.systemPackages = with pkgs; [
  git
  go
  python37
  mongodb
  redis
];

Save the configuration.nix file, and run the following command to update the system:

sudo nixos-rebuild switch

Step 3: Install Tsuru

Once you have installed the dependencies, you can proceed with installing Tsuru. There are two ways to install Tsuru:

Method 1: Using nix-shell

The easiest way to install Tsuru is to use the nix-shell command. The nix-shell command creates a temporary environment with all the dependencies required to run Tsuru. To install Tsuru using nix-shell, run the following command:

nix-shell https://github.com/tsuru/tsuru-shell/archive/master.tar.gz -A shell -I channels=https://nixos.org/channels/nixpkgs-unstable

This command fetches the latest version of the Tsuru source code and installs it into a temporary environment. Once the installation is complete, you can start using Tsuru by running the following command:

tsuru install

Method 2: Building from Source

Alternatively, you can build Tsuru from source. To do so, you need to perform the following steps:

1. Clone the Tsuru source code:

git clone https://github.com/tsuru/tsuru.git

2. Navigate to the Tsuru directory:

cd tsuru

3. Checkout the latest stable branch:

git checkout v1.7.0 # replace with latest version number

4. Build Tsuru:

make build

5. Install Tsuru:

sudo make install

Once the installation is complete, you can start using Tsuru by running the following command:

tsuru install

Conclusion

Congratulations! You have successfully installed Tsuru on nixOS latest. You can now deploy and manage your applications easily using Tsuru.
