Docker \u00c7ok A\u015famal\u0131 Olu\u015fturma: Hafif ve Etkin Konteynerler \u0130\u00e7in S\u0131rr\u0131n\u0131z<\/p>\n
Docker, uygulama da\u011f\u0131t\u0131m\u0131nda devrim yaratt\u0131. Ancak, olu\u015fturdu\u011funuz konteynerlerin boyutu ve g\u00fcvenli\u011fi her zaman ideal olmayabiliyor. Bu noktada, Docker’\u0131n sundu\u011fu g\u00fc\u00e7l\u00fc bir \u00f6zellik devreye giriyor: \u00c7ok A\u015famal\u0131 Olu\u015fturma (Multi-Stage Builds)<\/strong>. Bu makalede, \u00e7ok a\u015famal\u0131 olu\u015fturman\u0131n ne oldu\u011funu, nas\u0131l kullan\u0131ld\u0131\u011f\u0131n\u0131 ve neden \u00f6nemli oldu\u011funu detayl\u0131 bir \u015fekilde ele alaca\u011f\u0131z.<\/p>\n Standart bir Dockerfile ile uygulamam\u0131z\u0131 olu\u015fturdu\u011fumuzda, derleme ara\u00e7lar\u0131, ba\u011f\u0131ml\u0131l\u0131klar ve di\u011fer yard\u0131mc\u0131 dosyalar son g\u00f6r\u00fcnt\u00fcye dahil olur. Bu durum, konteyner boyutunu gereksiz yere art\u0131r\u0131r ve g\u00fcvenlik a\u00e7\u0131klar\u0131na yol a\u00e7abilir. \u00c7ok a\u015famal\u0131 olu\u015fturma ile bu sorunu ortadan kald\u0131rabiliriz. \u00d6ncelikle uygulamam\u0131z\u0131 derlemek i\u00e7in bir a\u015fama olu\u015ftururuz. Sonras\u0131nda, sadece derlenmi\u015f uygulama dosyalar\u0131n\u0131 i\u00e7eren daha k\u00fc\u00e7\u00fck ve g\u00fcvenli bir son g\u00f6r\u00fcnt\u00fc olu\u015fturmak i\u00e7in ba\u015fka bir a\u015fama kullan\u0131r\u0131z.

Her FROM komutu yeni bir a\u015fama ba\u015flat\u0131r. \u00d6rne\u011fin, ilk a\u015famada uygulamam\u0131z\u0131 derleriz ve ikinci a\u015famada sadece derlenmi\u015f \u00e7\u0131kt\u0131y\u0131 son g\u00f6r\u00fcnt\u00fcye kopyalar\u0131z. \u0130kinci a\u015fama, daha k\u00fc\u00e7\u00fck ve hafif bir temel g\u00f6r\u00fcnt\u00fc kullanabilir. Bu sayede, son konteyner boyutu \u00f6nemli \u00f6l\u00e7\u00fcde k\u00fc\u00e7\u00fcl\u00fcr.<\/p>\n Yukar\u0131daki \u00f6rnekte, ilk a\u015fama Node.js kullanarak uygulamam\u0131z\u0131 derliyor. \u0130kinci a\u015fama ise sadece derlenmi\u015f \u00e7\u0131kt\u0131lar\u0131 (\/app\/dist) Nginx temel g\u00f6r\u00fcnt\u00fcs\u00fcne kopyal\u0131yor.
