How to Install Pallet on Linux Mint Latest

Pallet is an open-source infrastructure provisioning tool designed to automate the deployment and management of cloud-based services. It helps you to manage your server infrastructure and automate the deployment of applications on clouds like Amazon EC2, Rackspace, and Joyent.

In this tutorial, we will walk you through the steps to install Pallet on Linux Mint Latest.

Prerequisites

Before you begin, make sure you have the following prerequisites:

• A Linux Mint Latest machine with sudo or root access.

Step 1 - Install Java

Pallet requires Java to run. You can install Java by running the following command:

sudo apt update
sudo apt install openjdk-8-jdk

After installation, verify the Java version by running the following command:

java -version

You should see the output with the Java version.

openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-8u282-b08-0ubuntu1~20.04-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode)

Step 2 - Install Leiningen

Leiningen is a popular build tool for Clojure. Pallet uses Leiningen to build, compile, and package its Java-based applications. Install Leiningen by running the following command:

sudo apt update
sudo apt install leiningen

The installation process will take some time to complete.

After installation, verify the Leiningen version by running the following command:

lein --version

You should see the output with the Leiningen version.

Leiningen 2.9.6 on Java 1.8.0_282 OpenJDK 64-Bit Server VM

Step 3 - Install Pallet

Now we are ready to install the Pallet tool. We will use the Leiningen command to install Pallet.

Run the following command to install Pallet as a local project.

lein new app pallet-local

You can choose a name other than "pallet-local" if you want. After executing the command, navigate to the project directory by running the following command:

cd pallet-local

Now, modify the pallet-local/project.clj file.

(defproject pallet-local "0.1.0-SNAPSHOT"
      :dependencies [[org.clojure/clojure "1.8.0"]
                     [pallet "0.9.5"]])

Add [pallet "0.9.5"] to the :dependencies vector to include the Pallet library in our project. After modifying the file, save and exit.

Finally, install Pallet by running the following command:

lein deps

This command downloads and installs all the required Pallet dependencies.

Step 4 - Test Pallet

Now that we have installed Pallet let's test it by creating a Hello World program.

Create a new file named hello_pallet.clj.

vim hello_pallet.clj

Paste the following code into the hello_pallet.clj file.

(ns hello-pallet.core
  (:require [pallet.compute :as compute]
            [pallet.crate.apt :as apt]))

(defn create-compute-service []
  (compute/compute-service
   {:provider :aws}))

(defn hello []
  (let [nodes (create-compute-service)]
    (doseq [node nodes]
      (println (str "Hello, " (compute/compute-name node), "!")))))

(hello)

This program creates a new Pallet compute service that we can use to interact with remote servers in the cloud. It then prints "Hello" and the name of the server.

Run the Hello World program by running the following command:

lein run -m hello-pallet.core

You should see the output with "Hello" and the name of the server.

Hello, server-1!

Conclusion

We have shown you how to install Pallet on Linux Mint Latest. You can now use Pallet to automate the deployment and management of your cloud-based services.

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!
