Herkese merhaba!

Uzun yıllardır bol miktarda kişisel zaman ve enerji harcayarak bilgimizi hepinizle paylaşıyoruz. Ancak şu andan itibaren bu blogu çalışır durumda tutabilmek için yardımınıza ihtiyacımız var. Yapmanız gereken tek şey, sitedeki reklamlardan birine tıklamak olacaktır, aksi takdirde hosting vb. masraflar nedeniyle maalesef yayından kaldırılacaktır. Teşekkürler.

Bu örnek Nginx, MySQL ve PHP-FPM docker container (debian:stretch-slim) kullanarak Symfony uygulamasını geliştirme DEV ortamında çalıştırılabilir hale getirir ve sadece en basidinden gerekli olan modüller yüklüdür yani gereksinimlerinize göre ayarlama yapabilirsiniz. Tüm yapmanız gereken aşağıdaki docker klasörünü ve Symfony uygulamanızın içine kopyalamak ve symfony/docker klasörü içindeyken docker-compose up -d komutunu çalıştırmaktır. Bu kadar!


Timezone


Her ne kadar ayarlar kendi gereksinimlerinize bağlı olsa da, sunucular için en güvenli zaman dilimi DST (Günışığı Tasarrufu) bağımlı olanlardan ziyade UTC'dir. Aşağıdaki örnekte Europe/London olarak ayarlıyorum (GMT - bu bir DST'dir), ama isterseniz tüm bu satırları kaldırabilir veya yalnızca UTC ile değiştirebilirsiniz.

Kurulum


$ docker-compose up -d --build

Test


Sadece curl http://localhost:8081 komutunu çalıştırın.
