Pallet is a powerful infrastructure orchestration solution that helps you automate the deployment and management of your applications in the cloud. In this tutorial, we will guide you through the process of installing Pallet on your Elementary OS Latest machine.
Before you can install Pallet on your Elementary OS Latest machine, you must make sure that:
Pallet is a Java-based application, which means that you need to have Java installed on your Elementary OS Latest machine before you can use it. To install Java, open the terminal and run the following command:
sudo apt-get install openjdk-8-jdk -y
This command will install the Java Development Kit (JDK) version 8 on your Elementary OS Latest machine.
Leiningen is a build automation and dependency management tool for Clojure projects. Since Pallet is built on Clojure, you need to have Leiningen installed on your Elementary OS Latest machine before you can install Pallet.
To install Leiningen, open the terminal and run the following command:
wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
sudo mv lein /usr/local/bin/
sudo chmod a+x /usr/local/bin/lein
lein --version
This command will download the Leiningen binary and move it to the /usr/local/bin directory. It will also give executable permissions to the Leiningen binary and verify the installation by showing the version of Leiningen.
Now that you have Java and Leiningen installed on your Elementary OS Latest machine, you are ready to install Pallet.
To install Pallet, open the terminal and run the following command:
lein new pallet my-pallet-project
cd my-pallet-project/
emacs project.clj
This command will create a new Pallet project in the my-pallet-project directory. It will also open the project.clj file for editing in the Emacs text editor.
In the project.clj file, you need to add the following line to the :dependencies section:
[palletops/pallet "0.9.5"]
Save and close the project.clj file.
Now, run the following command to download and install the Pallet dependencies:
lein deps
This command will download and install all the Pallet dependencies into your project.
To test if Pallet is working correctly, run the following command:
lein repl
This command will start the Leiningen REPL (Read-Eval-Print Loop), which is a tool for interactive development and experimentation with Clojure.
In the REPL, type the following commands:
(require '[pallet.compute.jclouds.compute-service :as compute])
(def service (compute/compute-service))
(println (compute/nodes service))
These commands will load the Pallet compute-service module, create a new compute service, and print a list of all the nodes in the compute service.
If you see a list of nodes in the output, then Pallet is working correctly on your Elementary OS Latest machine.
In this tutorial, you learned how to install Pallet on your Elementary OS Latest machine. Pallet is a powerful infrastructure orchestration solution that makes it easy to automate the deployment and management of your applications in the cloud. With Pallet, you can save a lot of time and effort in managing your cloud infrastructure, and focus on developing and running your applications.
