        Docker Kubernetes Nedir?<\/h2>\r\n\r\n\r\n\r\n

        Kubernetes ve Docker kavramlar\u0131 s\u00f6z konusu oldu\u011funda, s\u0131k\u00e7a kar\u015f\u0131la\u015f\u0131lan sorulardan biri de \u201cKubernetes mi yoksa Docker m\u0131<\/strong> kullan\u0131lmal\u0131 sorusudur. Asl\u0131nda her iki kavram da farkl\u0131 \u015feyleri ifade eder. Konuya \u00e7ok da fazla vak\u0131f olmayanlar\u0131n, birbirine uzak kavramlar oldu\u011funu d\u00fc\u015f\u00fcnd\u00fc\u011f\u00fc ve varsayd\u0131\u011f\u0131 Docker ve Kubernetes aras\u0131ndaki fark\u0131 ifade ederek ba\u015flamak daha do\u011fru olacakt\u0131r.<\/p>\r\n\r\n\r\n\r\n

        \u00d6ncelikle, Kubernetes ve Docker aras\u0131nda bir se\u00e7im yap\u0131lmas\u0131 gerekmemektedir. Kubernetes ve Docker, kapsay\u0131c\u0131l\u0131 uygulamalar\u0131n derlenmesinde, teslim edilmesinde ve \u00f6l\u00e7eklendirmesi ile olduk\u00e7a iyi bir performansla \u00e7al\u0131\u015fan, birbirinden farkl\u0131 teknolojiler olmaktad\u0131r.<\/p>\r\n\r\n\r\n\r\n

        Docker, bulut platformlar\u0131nda uygulamalar\u0131n da\u011f\u0131t\u0131m\u0131n\u0131 ya da \u015firket i\u00e7i ortamlarda ta\u015f\u0131nabilir \u00f6zellikte, kendine yetebilen kapsay\u0131c\u0131lar bi\u00e7imiyle otomatikle\u015ftirme i\u015flemini sa\u011flayan, a\u00e7\u0131k kaynak teknolojisi ve geni\u015f kapsaml\u0131 dosya bi\u00e7imi olarak ifade edilmektedir. Docker Inc. ise, a\u00e7\u0131k kaynakl\u0131 Docker teknolojisinin Microsoft gibi bulut platformu sa\u011flay\u0131c\u0131s\u0131nda, Linux ve Windows i\u015fletim sistemleri \u00fczerinde \u00e7al\u0131\u015fmas\u0131n\u0131 destekleyen \u015firketlerden biri olmaktad\u0131r.\u00a0<\/p>\r\n\r\n\r\n\r\n

        Ortamlar\u0131 izole etme, kapsay\u0131c\u0131l\u0131k haline d\u00f6n\u00fc\u015ft\u00fcrme ihtiyac\u0131 ve fikri yeni de\u011fildir ancak Docker son zamanlarda varsay\u0131lan kapsay\u0131c\u0131l\u0131k halinde kullan\u0131lmaktad\u0131r. Docker, kapsay\u0131c\u0131l\u0131k \u00f6zelli\u011findeki uygulamalar\u0131n paketlenerek da\u011f\u0131t\u0131lmas\u0131nda standart sa\u011flamaktad\u0131r. Ancak s\u00fcre\u00e7 i\u00e7erisinde bu durum karma\u015f\u0131k bir hale d\u00f6n\u00fc\u015febilmektedir.<\/p>\r\n\r\n\r\n\r\n

        \u00c7ok say\u0131daki kapsay\u0131c\u0131n\u0131n koordine edilmesi zaman almaktad\u0131r. Ayn\u0131 \u015fekilde kapsay\u0131c\u0131lar aras\u0131nda ileti\u015fim kurma ve \u00f6l\u00e7eklendirme i\u015flemleri ayr\u0131 bir deste\u011fe ihtiya\u00e7 duymaktad\u0131r. Bu noktada ise Kubernetes devreye girmekte ve t\u00fcm a\u015famalarda destek sunmaktad\u0131r. Kubernetes, kapsay\u0131c\u0131lar\u0131n \u00e7al\u0131\u015fmalar\u0131n\u0131 ve yerlerini denetlemeye y\u00f6nelik API<\/strong> (A<\/strong>pplication P<\/strong>rogramming I<\/strong>nterface) uygulama programlama aray\u00fcz\u00fc sunan, kaynaklar\u0131 d\u00fczenlemek i\u00e7in yarat\u0131lan yaz\u0131l\u0131m olmaktad\u0131r.
