Rocky Linux 8 \u00dczerine Docker Compose Kurulumu ve Kullan\u0131m\u0131<\/h2>\n

Rocky Linux 8, CentOS’un kararl\u0131 ve topluluk destekli bir halefi olarak, sunucu ortamlar\u0131nda ve geli\u015ftirme i\u015f ak\u0131\u015flar\u0131nda giderek daha fazla tercih edilmektedir. Modern uygulama geli\u015ftirme ve da\u011f\u0131t\u0131m s\u00fcre\u00e7lerinde konteyner teknolojileri merkezi bir rol oynamaktad\u0131r. Docker, uygulamalar\u0131 ba\u011f\u0131ml\u0131l\u0131klar\u0131yla birlikte hafif, ta\u015f\u0131nabilir konteynerler i\u00e7inde paketleyerek bu s\u00fcreci kolayla\u015ft\u0131r\u0131r. Ancak ger\u00e7ek d\u00fcnya uygulamalar\u0131 genellikle tek bir konteynerden fazlas\u0131n\u0131 gerektirir; bir veritaban\u0131, bir \u00f6n u\u00e7, bir arka u\u00e7 servisi ve belki de bir \u00f6nbellek gibi birden \u00e7ok servisten olu\u015fur. \u0130\u015fte bu noktada Docker Compose devreye girer.<\/p>\n

Docker Compose, birden \u00e7ok konteynerden olu\u015fan Docker uygulamalar\u0131n\u0131 tan\u0131mlamak ve \u00e7al\u0131\u015ft\u0131rmak i\u00e7in bir ara\u00e7t\u0131r. Tek bir YAML dosyas\u0131 kullanarak t\u00fcm uygulama servislerinizi yap\u0131land\u0131rabilir, ba\u015flatabilir, durdurabilir ve y\u00f6netebilirsiniz. Bu, karma\u015f\u0131k \u00e7oklu servis mimarilerini basitle\u015ftirerek geli\u015ftiricilerin ve sistem y\u00f6neticilerinin hayat\u0131n\u0131 \u00f6nemli \u00f6l\u00e7\u00fcde kolayla\u015ft\u0131r\u0131r.<\/p>\n

Bu kapsaml\u0131 teknik makalede, Rocky Linux 8 i\u015fletim sistemi \u00fczerine Docker Engine ve ard\u0131ndan Docker Compose’u nas\u0131l kuraca\u011f\u0131n\u0131z\u0131 ad\u0131m ad\u0131m a\u00e7\u0131klayaca\u011f\u0131z. Ayr\u0131ca, temel Docker Compose komutlar\u0131n\u0131 ve docker-compose.yml<\/code> dosyas\u0131n\u0131n yap\u0131s\u0131n\u0131 anlayarak \u00f6rnek bir \u00e7oklu konteyner uygulamas\u0131n\u0131 nas\u0131l da\u011f\u0131taca\u011f\u0131n\u0131z\u0131 ve y\u00f6netece\u011finizi g\u00f6sterece\u011fiz. Makalenin sonunda, Docker Compose ile \u00e7al\u0131\u015f\u0131rken kar\u015f\u0131la\u015fabilece\u011finiz yayg\u0131n sorunlara ve en iyi uygulamalara da de\u011finece\u011fiz. Bu k\u0131lavuz, hem Docker ve konteyner teknolojilerine yeni ba\u015flayanlar hem de mevcut bilgilerini Rocky Linux 8 ortam\u0131nda peki\u015ftirmek isteyen deneyimli kullan\u0131c\u0131lar i\u00e7in de\u011ferli bir kaynak olacakt\u0131r.<\/p>\n

Ad\u0131m 3: Docker Compose Kurulumu<\/h3>\n
Docker Engine ba\u015far\u0131yla kurulduktan sonra, s\u0131ra Docker Compose’a gelir. Docker Compose, Docker Engine gibi, docker-compose<\/code> komutunu kullanarak kontrol edilen ayr\u0131 bir ara\u00e7t\u0131r.<\/p>\n
Docker Compose Nedir?<\/h4>\n
Daha \u00f6nce de belirtildi\u011fi gibi, Docker Compose, \u00e7oklu konteyner Docker uygulamalar\u0131n\u0131 tan\u0131mlamak ve \u00e7al\u0131\u015ft\u0131rmak i\u00e7in kullan\u0131lan bir ara\u00e7t\u0131r. Bir docker-compose.yml<\/code> dosyas\u0131 kullanarak, uygulaman\u0131z\u0131n t\u00fcm servislerini, a\u011flar\u0131n\u0131 ve birimlerini tek bir dosyada yap\u0131land\u0131rabilirsiniz. Bu, uygulaman\u0131z\u0131n t\u00fcm bile\u015fenlerini tek bir komutla ba\u015flatman\u0131za olanak tan\u0131r.<\/p>\n
Kurulum Y\u00f6ntemleri<\/h4>\n
Docker Compose’u kurman\u0131n birka\u00e7 yolu vard\u0131r, ancak en yayg\u0131n ve \u00f6nerilen y\u00f6ntem, Docker’\u0131n GitHub deposundan do\u011frudan ikili (binary) dosyay\u0131 indirmektir. Eski s\u00fcr\u00fcmler Python pip<\/code> arac\u0131yla kurulabiliyordu, ancak Docker Compose v2 ile birlikte bu y\u00f6ntem art\u0131k \u00f6nerilmemektedir. Docker Compose v2, Go dilinde yeniden yaz\u0131lm\u0131\u015f ve docker compose<\/code> olarak Docker CLI’ye entegre edilmi\u015ftir (ayr\u0131 bir docker-compose<\/code> ikilisi olarak da kullan\u0131labilir).<\/p>\n
Binary \u0130ndirme Y\u00f6ntemi ile Kurulum<\/h4>\n
Bu y\u00f6ntem, en g\u00fcncel ve kararl\u0131 Docker Compose s\u00fcr\u00fcm\u00fcn\u00fc kurman\u0131n en basit ve en g\u00fcvenilir yoludur.<\/p>\n
