Merhaba, bu makalede Flask uygulaman\u0131z\u0131 Docker Compose kullanarak nas\u0131l da\u011f\u0131taca\u011f\u0131n\u0131z\u0131 ad\u0131m ad\u0131m a\u00e7\u0131klayaca\u011f\u0131z. Docker Compose, \u00e7oklu konteyner uygulamalar\u0131n\u0131 tan\u0131mlamak ve y\u00f6netmek i\u00e7in kullan\u0131\u015fl\u0131 bir ara\u00e7t\u0131r. Bu sayede, uygulaman\u0131z\u0131n farkl\u0131 bile\u015fenlerini (\u00f6rne\u011fin web sunucusu, veritaban\u0131, \u00f6nbellek) ayr\u0131 konteynerlerde \u00e7al\u0131\u015ft\u0131rabilir ve bunlar\u0131 kolayca y\u00f6netebilirsiniz.<\/p>\n
* Docker ve Docker Compose kurulu olmal\u0131. Kurulum bilgisi i\u00e7in [Docker’\u0131n resmi web sitesini](https:\/\/www.docker.com\/) ziyaret edebilirsiniz.
\n* Python 3 ve Flask kurulu olmal\u0131.

Bu Docker Compose dosyas\u0131 \u015funlar\u0131 yapar:<\/p>\n
* **version: ‘3.8’:** Docker Compose s\u00fcr\u00fcm\u00fcn\u00fc belirtir.
\n* **services:** Uygulama bile\u015fenlerini tan\u0131mlar.
\n* **web:** Flask uygulamas\u0131 i\u00e7in bir hizmet tan\u0131mlar.
\n* **build: .:** Dockerfile’\u0131 kullanarak bir g\u00f6r\u00fcnt\u00fc olu\u015fturur.
\n* **ports:** Konteynere 5000 portunu, ana makineye 5000 portuna e\u015fler.
\n* **volumes:** Ana makinedeki `app` dizinini konteynerdeki `\/app` dizinine e\u015fler.
\n* **depends_on:** `db` hizmetine ba\u011fl\u0131 oldu\u011funu belirtir.
\n* **db:** PostgreSQL veritaban\u0131 i\u00e7in bir hizmet tan\u0131mlar.

Docker Compose dosyas\u0131 olu\u015fturulduktan sonra, uygulaman\u0131z\u0131 da\u011f\u0131tmak i\u00e7in a\u015fa\u011f\u0131daki komutlar\u0131 kullanabilirsiniz:<\/p>\n
“`bash
\ndocker-compose up -d
\n“`<\/p>\n
Bu komut, Docker Compose dosyas\u0131ndaki t\u00fcm hizmetleri arka planda \u00e7al\u0131\u015ft\u0131r\u0131r. Uygulaman\u0131z\u0131 durdurmak i\u00e7in a\u015fa\u011f\u0131daki komutu kullanabilirsiniz:<\/p>\n
“`bash
\ndocker-compose down
\n“`<\/p>\n
Uygulama da\u011f\u0131t\u0131ld\u0131ktan sonra, ana makinenizin 5000 portuna eri\u015ferek uygulamaya eri\u015febilirsiniz. \u00d6rne\u011fin, `http:\/\/localhost:5000` adresini taray\u0131c\u0131n\u0131zda ziyaret edebilirsiniz.<\/p>\n
* **G\u00fcvenlik:** \u00dcretim ortam\u0131nda, uygulaman\u0131z\u0131 g\u00fcvenli bir \u015fekilde da\u011f\u0131tman\u0131z gerekir. Bunu, uygulaman\u0131z\u0131 g\u00fcvenli bir a\u011f arkas\u0131na yerle\u015ftirerek, SSL sertifikas\u0131 kullanarak veya di\u011fer g\u00fcvenlik \u00f6nlemlerini alarak yapabilirsiniz.
\n* **\u00d6l\u00e7eklenebilirlik:** Docker Compose, uygulaman\u0131z\u0131 \u00f6l\u00e7eklendirmek i\u00e7in de kullan\u0131labilir. \u00d6rne\u011fin, `web` hizmetini \u00e7o\u011faltmak i\u00e7in a\u015fa\u011f\u0131daki komutu kullanabilirsiniz:<\/p>\n
“`bash
\ndocker-compose up -d –scale web=3
\n“`<\/p>\n
Bu, `web` hizmetinden \u00fc\u00e7 kopya \u00e7al\u0131\u015ft\u0131racakt\u0131r.<\/p>\n
* **Monit\u00f6rleme:** Uygulaman\u0131z\u0131 izlemek ve hatalar\u0131 ay\u0131klamak i\u00e7in Prometheus, Grafana gibi ara\u00e7lar kullanabilirsiniz.<\/p>\n
