How to Install SheepDog on NixOS Latest

SheepDog is a distributed storage system for KVM/QEMU. It provides a simple and easy-to-use mechanism to distribute storage in a cluster environment. In this tutorial, we will go through the steps to install SheepDog on NixOS Latest.

Prerequisites

Before proceeding with this tutorial, you should have:

• A running NixOS Latest system
• An active internet connection

Step 1: Add the SheepDog Package Channel

SheepDog is not available in the official NixOS Latest package repository. Therefore, we need to add the SheepDog package channel to our system.

To do that, add the following code to your /etc/nixos/configuration.nix file:

  nixpkgs.config.packageOverrides = pkgs: {
    sheepdog = pkgs.fetchgit {
      url = https://github.com/sheepdog/sheepdog;
      rev = "<commit-hash>";
      sha256 = "<commit-hash>.hash";
    };
  };

Replace the <commit-hash> with the latest commit hash from SheepDog's GitHub repository. You can get the commit hash by visiting its repository at https://github.com/sheepdog/sheepdog.

Once you have added the package channel, save the changes and exit the file.

Step 2: Install SheepDog

To install SheepDog, run the following command:

sudo nix-env -f '<nixpkgs>' -iA sheepdog

This command will install the SheepDog package from the newly added package channel.

Step 3: Configure SheepDog

After installation, we need to configure SheepDog to work with our cluster.

To configure SheepDog, create a configuration file at /etc/sheepdog/sheepdog.conf. In this file, you need to specify the IP addresses of all the nodes in your cluster. You can use the following example configuration:

[default]
  zookeeper: 127.0.0.1:2181
  server: <node1-ip>, <node2-ip>, <node3-ip>

Replace the <node1-ip>, <node2-ip>, and <node3-ip> with the IP addresses of the nodes in your cluster. Make sure to use the same configuration on all the nodes in your cluster.

Step 4: Start the SheepDog Service

After configuration, start the SheepDog service by running the following command:

sudo systemctl start sheepdog

This command will start the SheepDog service on your system.

Step 5: Verify the SheepDog Installation

To verify that SheepDog is installed and running correctly, run the following command:

sudo sheep -v

This command will display the version of SheepDog installed on your system.

Congratulations! You have successfully installed and configured SheepDog on NixOS Latest. You can now use SheepDog to distribute storage in your cluster environment.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
