In this guide, we'll walk you through setting up a zero-downtime deployment script for Laravel Forge, empowering you to deploy with confidence and keep your application always on.

What is Zero Downtime Deployment?

Zero downtime deployment is a deployment strategy that allows you to deploy new versions of your software without taking the application offline or causing any disruptions to the end users. It is essential for businesses that require high availability and need to ensure that their applications are always live and responsive.

Why Use Zero Downtime Deployment?

  1. Improved User Experience: Users will not experience any downtime or disruption while you deploy new updates.

  2. Higher Customer Satisfaction: Ensuring continuous availability helps retain users and prevent revenue loss.

  3. Minimized Risk: Reduces the risk of errors and issues during deployment, as you can easily roll back changes if necessary.

Setting Up Zero Downtime Deployment for Laravel Forge

To set up a zero-downtime deployment process in Laravel Forge, you need to create a deployment script that will handle the entire process smoothly. Here is a step-by-step guide to help you get started.

Step 1: Initial Setup

Before starting the deployment process, define some essential variables to set up your environment:

shCopy code
DOMAIN=example.com
PROJECT_REPO=

These variables set the stage for the deployment process, including the domain name, project repository, and the number of releases to keep.

Step 2: Cloning Repository and Configuring the Environment

The deployment script begins by creating a unique release directory and cloning the project repository into it:

shCopy code
cd /home/forge/$DOMAIN

mkdir -p 

Next, the script copies the .env file from the project directory to configure the environment for the new release:

shCopy code
printf 

Step 3: Running Laravel Commands and Installing Dependencies

To ensure that the new release is correctly set up, the script installs Composer dependencies, restarts PHP-FPM, and runs Laravel migrations:

shCopy code
$FORGE_COMPOSER install --no-dev --no-interaction --prefer-dist --optimize-autoloader

( flock -w 

Additionally, the script installs NPM dependencies and generates necessary JavaScript and CSS files:

shCopy code
printf 

Step 4: Building and Linking the Deployment Directory

Once all the dependencies are installed and Laravel commands are executed, the script links the deployment directory to the current directory:

shCopy code
printf 

Step 5: Cleaning Up and Maintaining Releases

To maintain a clean environment and save storage, the script performs cleanup tasks to delete failed and old successful releases:

shCopy code
printf 

Conclusion

By following the steps outlined in this guide, you can achieve zero downtime deployment for your Laravel Forge application. This approach will help maintain an uninterrupted user experience, improve customer satisfaction, and minimize risks associated with deployment errors. Remember to always test your deployment script in a staging environment before applying it to production.
