Why Deployment Automation is Key for Business & Our Solution

In the world of web development, especially when it comes to powerful and complex platforms like Magento 2, automating deployment processes is not just a convenience - it’s a necessity. Manually deploying changes to a production server can lead to errors, wasted time, and, most importantly, website downtime. In this article, we’ll explain why automating website deployment processes is key to business’s success and how we help our clients make this process simple and secure.

Why is it important to automate deployment processes in Magento 2?

1. Less errors
   When updates are done manually, there’s always a risk of missing something or making a mistake. This can lead to website malfunctions, which negatively impact sales. Automation eliminates such errors.
2. Standardized processes
   When multiple developers are working on a project, it’s crucial that everyone follows the same deployment process. This eliminates confusion and ensures that every step is executed correctly.
3. Stable operations
   Automated deployment systems allow for quick rollbacks if something goes wrong. This means the website will continue to operate without downtime, even if issues arise.
4. Simplified work with multiple environments
   In Magento 2 development, multiple environments are often used: local, staging, and production. Automation makes it easy to deploy changes to any of these environments without fear of errors.

How do we automate website updates?

We use Deployer.org to make the process of updating Magento 2 websites as simple and secure as possible.

Example deploy.php:

1<?php
2namespace Deployer;
3
4// Base recipe of Magento 2 deployment
5require 'recipe/magento2.php';
6
7// ==================== BASIC CONFIGURATIONS ====================
8// Your Git repository
9set('repository', 'git@github.com:example.git');
10
11// Keep 3 releases for rollback
12set('keep_releases', 3);
13
14// Default deployment environment
15set('default_stage', 'prod');                    
16
17// ==================== MAGENTO SPECIFIC ====================
18
19// Locales for static content deploy
20set('static_content_locales', 'en_US de_DE');
21  
22// Shared directories (persist between deployments)
23set('shared_dirs', [
24    'pub/media',      // Media files
25    'var/log',        // Logs
26    'var/report',     // Error reports
27    'var/export',     // Data exports
28    'var/import',     // Data imports
29    'var/session',    // PHP sessions
30]);
31
32// Shared files (won't be overwritten)
33set('shared_files', [
34    'app/etc/env.php',  // Magento configuration
35]);
36
37// ==================== CUSTOM TASKS ====================
38
39task('cache:clear:opcache, function() {
40    run('sudo service php8.3-fpm restart'); // Restart PHP-FPM
41    run('sudo service varnish restart');    // Restart Varnish
42});
43
44// ==================== DEPLOYMENT FLOW ====================
45
46// Run cache clearing after deploy
47after('deploy:symlink', 'cache:clear:opcache');
48
49// Unlock deploy on failure
50after('deploy:failed', 'deploy:unlock'); 
51
52// ==================== HOST CONFIGURATION ====================
53
54host('your-server-name')
55    ->setHostname('your-server.com')
56    ->setRemoteUser('your-user')
57    ->set('deploy_path', '/var/www/html') // Deployment directory
58;
59
60// ==================== COMMAND FOR DEPLOY ====================
61// vendor/bin/dep deploy <host>
Copy

Here’s how it works:

1. A unified process for everyone
   We configure the system so that all updates follow the same workflow. This eliminates errors and makes the process predictable.
2. Deployment broken into stages
   The deployment process is divided into stages, such as:
3. • Cloning the repository.
   • Installing dependencies via Composer.
   • Applying database migrations.
   • Clearing Magento cache.
   • Restarting services (e.g., PHP-FPM, redis, varnish).

All these steps are automated, ensuring no step is missed.

3. Fast deployment
   Instead of manually copying files and configuring the server, we use specialized tools that handle this automatically. This saves a lot of time during development.
4. Safety and rollback capabilities
   If something goes wrong after an update, the system automatically restores the website to its previous working state. This helps avoid downtime and customer loss.

Benefits of automating deployment in Magento 2

• Speed: The deployment process takes just minutes.
• Reliability: Minimized errors thanks to a standardized update process.
• Flexibility: Customizable to meet the specific needs of the project.
• Scalability: Easily adapts to large projects with multiple servers.

Deploying to Different Environments

One of the key advantages of automation with Deployer is the ability to deploy seamlessly to any environment — whether it’s production or staging. The process is managed with the same command, and the only difference is specifying the target environment.

Deploying to Production

To release changes to production, a developer needs to:

1. Ensure all changes are committed and pushed to Git.
2. Navigate to the project’s root directory on their local machine.
3. Run the command: 

1vendor/bin/dep deploy prod
Copy

This triggers all deployment steps: code cloning, dependency installation, database updates, cache clearing, and service restarts.

Deploying to Staging

For deploying to a staging environment (e.g., for client preview or internal testing), the same workflow applies — just with a different environment flag:

1vendor/bin/dep deploy stage
Copy

The process remains identical: the same deployment script, the same steps, the same error safeguards, and rollback capabilities.

Why This Matters

By using the same logic for both production and staging, the process becomes transparent and predictable. Our clients don’t just get automation — they gain stability and confidence in every release:

1. No fear of production deployments: Identical workflows eliminate surprises.
2. Consistency across environments: Staging mirrors production, reducing "it works on my machine" risks.
3. Early error detection: Issues caught in staging won’t reach production, since both follow the same rules.

This approach ensures reliable delivery across all environments while minimizing risks from human error, configuration drift, or post-release failures.

Conclusion

Automating website deployment processes is more than just a technical detail – it’s an important step towards running a successful online store. It helps avoid errors, saves time, and ensures stable website performance.
