Magento 2 Deployment & CLI

Before writing code

Fetch live docs:

1. Fetch https://experienceleague.adobe.com/en/docs/commerce-operations/configuration-guide/cli/set-mode for deployment modes
2. Fetch https://experienceleague.adobe.com/en/docs/commerce-operations/configuration-guide/cli/static-view/static-view-file-deployment for static content deploy
3. Web-search magento 2 zero downtime deployment for zero-downtime strategies

Deployment Modes

bin/magento deploy:mode:show
bin/magento deploy:mode:set production
bin/magento deploy:mode:set developer

Production Deployment Steps

Standard Sequence

# 1. Enable maintenance mode
bin/magento maintenance:enable

# 2. Pull latest code (git pull, composer install)
composer install --no-dev --optimize-autoloader

# 3. Run setup upgrade (applies db_schema changes and patches)
bin/magento setup:upgrade

# 4. Compile DI (generates interceptors, factories, proxies)
bin/magento setup:di:compile

# 5. Deploy static content (CSS, JS, images, templates)
bin/magento setup:static-content:deploy en_US --jobs=4

# 6. Flush cache
bin/magento cache:flush

# 7. Disable maintenance mode
bin/magento maintenance:disable

Static Content Deploy Strategies

• quick — minimizes deployment time by reusing files across locales (default in 2.4+)
• compact — minimizes disk space
• standard — full deployment
• Flags: --exclude-theme, --no-html-minify, --jobs=N for parallelism

Zero-Downtime Deployment

Pipeline Deployment

Build and deploy on separate systems:

1. Build server: setup:di:compile + setup:static-content:deploy
2. Transfer artifacts to production
3. Production: setup:upgrade --keep-generated (no recompilation)

Blue-Green Deployment

Two identical environments with load balancer switching:

• Native support since 2.4.4: deployment/blue_green/enabled in app/etc/env.php
• Deploy to inactive environment, test, switch traffic
• Instant rollback by switching back

Symlink Switching

• Deploy to versioned directories (releases/20260214/)
• Switch current symlink to new release
• Shared directories for var/, pub/media/, app/etc/env.php
• Tools: Deployer (deployer.org), Capistrano, custom scripts

Essential CLI Commands

Module Management

bin/magento module:enable VendorName_ModuleName
bin/magento module:disable VendorName_ModuleName
bin/magento module:status

Cache Management

bin/magento cache:clean          # Clean invalidated cache types
bin/magento cache:flush          # Flush all cache storage
bin/magento cache:status         # Show cache type status
bin/magento cache:enable <type>
bin/magento cache:disable <type>

Indexer Management

bin/magento indexer:reindex
bin/magento indexer:status
bin/magento indexer:set-mode schedule

Cron

bin/magento cron:run
bin/magento cron:install

Admin

bin/magento admin:user:create
bin/magento admin:user:unlock <username>

Development

bin/magento dev:profiler:enable
bin/magento dev:template-hints:enable
bin/magento setup:config:set --<option>=<value>

CI/CD Pipeline Pattern

1. Lint/Static Analysis: PHP_CodeSniffer, PHPStan, Magento coding standard
2. Unit Tests: vendor/bin/phpunit -c dev/tests/unit/phpunit.xml.dist
3. Build: composer install --no-dev, setup:di:compile, setup:static-content:deploy
4. Integration Tests (optional, slow): against test database
5. Deploy: transfer artifacts, setup:upgrade, cache flush
6. Smoke Test: verify critical pages load

Best Practices

• Never run setup:di:compile or setup:static-content:deploy on production during traffic
• Use pipeline deployment for zero-downtime
• Use --jobs=N for parallel static content deployment
• Automate deployment — manual steps are error-prone
• Always take database backups before setup:upgrade
• Test deployment on staging before production
