🛠️ Why Shell Script Automation?

Automating application deployments saves time and reduces human errors. In this blog, I’ll walk you through deploying a Spring Boot WAR app inside a Vagrant-managed Ubuntu machine using a Shell Script. All actions are visualized step-by-step with real screenshots. Perfect for beginners in DevOps, scripting, or system setup!

📦 Prerequisites

Installed: Git, Vagrant, VirtualBox

Basic knowledge of Linux terminal

A Spring Boot WAR file (included in the GitHub repo)

📁 Step 1: Clone the Project

Open the VS code

Type the following command git clone https://github.com/SAFI-ULLAHSAFEER/Shell-Script

📂 Step 4: Navigate to Your Spring Boot App Directory

Start the Vagrant Box

🛠️ This command will automatically create and configure a virtual Linux machine for you, .This command logs you into the virtual Ubuntu machine where everything will run.

As you can see the black console screen only we called it as a multi-user.target in linux.

Now Next Step is SSH Into the Machine

After that Navigate to Your Spring Boot App Directory
By default, Vagrant shares your local directory under /vagrant.

After that next step is Create setup.sh Script

Now the next step is to Make the Script Executable and Run

chmod +x setup.sh
sudo ./setup.sh

This will:

Update packages

Install Java and Tomcat

Deploy your WAR file

Restart Tomcat

Now the NeXT Step is Check the IP Address by running command:
ip a

The following ip address of machine will appear

Now the next Step is Access Your App in the Browser

then press enter and the following screen will appear

🚀 Congratulations! If everything worked—you’ll see your Spring Boot app live!

Exit and Destroy the Vagrant Machine (Cleanup)
After verifying the app in the browser, clean up your VM:

exit
vagrant destroy

This command:

Logs out of the VM

Prompts you to confirm destroying the environment

Frees up system resources
