Bu makale, Kubernetes’in ne oldu\u011funu, neden bu kadar kritik oldu\u011funu ve karma\u015f\u0131k mimarisinin temel bile\u015fenlerini detayl\u0131 bir \u015fekilde inceleyecektir.<\/p>\n
Kubernetes, a\u00e7\u0131k kaynakl\u0131 bir konteyner orkestrasyon platformudur. Temel amac\u0131, konteynerle\u015ftirilmi\u015f i\u015f y\u00fcklerini ve servislerini otomatik olarak da\u011f\u0131tmak, \u00f6l\u00e7eklendirmek ve y\u00f6netmektir. Google taraf\u0131ndan geli\u015ftirilen ve daha sonra Cloud Native Computing Foundation’a (CNCF) ba\u011f\u0131\u015flanan Kubernetes, modern uygulama geli\u015ftirme ve operasyonlar\u0131n\u0131n omurgas\u0131 haline gelmi\u015ftir.<\/p>\n
Uygulamalar\u0131n ve ba\u011f\u0131ml\u0131l\u0131klar\u0131n\u0131n izole edilmi\u015f, ta\u015f\u0131nabilir birimler halinde paketlenmesini sa\u011flayan konteyner teknolojisi (\u00f6zellikle Docker), yaz\u0131l\u0131m geli\u015ftirme s\u00fcre\u00e7lerini devrim niteli\u011finde de\u011fi\u015ftirdi. Geli\u015ftiriciler, uygulamalar\u0131n\u0131 farkl\u0131 ortamlarda (geli\u015ftirme, test, \u00fcretim) tutarl\u0131 bir \u015fekilde \u00e7al\u0131\u015ft\u0131rabilmenin avantaj\u0131n\u0131 ya\u015fad\u0131. Ancak, y\u00fczlerce veya binlerce konteyneri manuel olarak y\u00f6netmek k\u0131sa s\u00fcrede s\u00fcrd\u00fcr\u00fclemez bir hale geldi.<\/p>\n
Tek bir konteyneri y\u00f6netmek kolay olsa da, mikroservis tabanl\u0131 bir mimaride \u00e7al\u0131\u015fan birden fazla konteyneri da\u011f\u0131tmak, a\u011flar\u0131n\u0131 yap\u0131land\u0131rmak, depolama sa\u011flamak, y\u00fck dengelemek, hatalar\u0131 ele almak ve \u00f6l\u00e7eklendirmek karma\u015f\u0131k bir i\u015ftir. \u0130\u015fte tam bu noktada Kubernetes devreye girer. Kubernetes, bu operasyonel y\u00fck\u00fc otomatize ederek geli\u015ftiricilerin ve operasyon ekiplerinin ana i\u015flerine odaklanmas\u0131n\u0131 sa\u011flar.<\/p>\n
Kubernetes, bir “k\u00fcme” (cluster) mimarisi \u00fczerinde \u00e7al\u0131\u015f\u0131r.

Temel olarak iki ana bile\u015fen t\u00fcr\u00fc vard\u0131r: Kontrol D\u00fczlemi (Control Plane) ve \u00c7al\u0131\u015fan D\u00fc\u011f\u00fcmler (Worker Nodes).<\/p>\n
Bir Kubernetes k\u00fcmesi, en az bir ana d\u00fc\u011f\u00fcm (Master Node) ve bir veya daha fazla \u00e7al\u0131\u015fan d\u00fc\u011f\u00fcmden (Worker Node) olu\u015fur. Ana d\u00fc\u011f\u00fcm, k\u00fcmenin beyni gibidir; t\u00fcm k\u00fcme etkinliklerini y\u00f6netir ve koordine eder. \u00c7al\u0131\u015fan d\u00fc\u011f\u00fcmler ise, konteynerle\u015ftirilmi\u015f uygulamalar\u0131n\u0131z\u0131 \u00e7al\u0131\u015ft\u0131ran makinelerdir.<\/p>\n

D\u00fc\u011f\u00fcm kaynak gereksinimleri, politikalar, etiketler ve di\u011fer k\u0131s\u0131tlamalar gibi fakt\u00f6rleri dikkate alarak en uygun d\u00fc\u011f\u00fcm\u00fc se\u00e7er.<\/p>\n
Bu bile\u015fen, farkl\u0131 kontrol\u00f6rleri tek bir i\u015flemde birle\u015ftirir. Kontrol\u00f6rler, k\u00fcmenin mevcut durumunu g\u00f6zlemler ve istenen duruma ula\u015fmak i\u00e7in de\u011fi\u015fiklikler yapar. \u00d6rne\u011fin:<\/p>\n

Kubernetes, modern bulut yerel uygulamalar\u0131n geli\u015ftirilmesi ve da\u011f\u0131t\u0131lmas\u0131nda devrim yaratan g\u00fc\u00e7l\u00fc bir platformdur. Karma\u015f\u0131k mimarisi, kontrol d\u00fczlemi ve \u00e7al\u0131\u015fan d\u00fc\u011f\u00fcm bile\u015fenlerinin uyumlu \u00e7al\u0131\u015fmas\u0131yla konteyner orkestrasyonunu otomatize eder. Pod'lar, Deployment'lar ve Service'ler gibi temel nesneleri anlayarak, geli\u015ftiriciler ve operasyon ekipleri uygulamalar\u0131n\u0131 daha verimli, \u00f6l\u00e7eklenebilir ve dayan\u0131kl\u0131 hale getirebilirler. Kubernetes'in sundu\u011fu bu sa\u011flam altyap\u0131, i\u015fletmelerin dijital d\u00f6n\u00fc\u015f\u00fcm yolculuklar\u0131nda kritik bir rol oynamaya devam edecektir.<\/p>\n
S\u0131k\u00e7a Sorulan Sorular (SSS)<\/h2>\nKubernetes ve Docker aras\u0131ndaki fark nedir?<\/h3>\n
Docker, konteyner olu\u015fturmak ve \u00e7al\u0131\u015ft\u0131rmak i\u00e7in bir ara\u00e7 setidir (konteyner \u00e7al\u0131\u015fma zaman\u0131). Kubernetes ise, Docker gibi konteynerleri b\u00fcy\u00fck \u00f6l\u00e7ekte y\u00f6netmek, da\u011f\u0131tmak ve orkestre etmek i\u00e7in kullan\u0131lan bir platformdur. Kubernetes, Docker'\u0131 bir alt bile\u015fen olarak kullanabilir.<\/p>\n
Bir Kubernetes k\u00fcmesi ka\u00e7 ana d\u00fc\u011f\u00fcmden olu\u015fmal\u0131d\u0131r?<\/h3>\n
Geli\u015ftirme veya test ortamlar\u0131 i\u00e7in tek bir ana d\u00fc\u011f\u00fcm yeterli olabilir. Ancak \u00fcretim ortamlar\u0131 i\u00e7in y\u00fcksek eri\u015filebilirlik sa\u011flamak amac\u0131yla genellikle en az \u00fc\u00e7 ana d\u00fc\u011f\u00fcmden olu\u015fan bir k\u00fcme \u00f6nerilir. Bu, bir ana d\u00fc\u011f\u00fcm\u00fcn ar\u0131zalanmas\u0131 durumunda k\u00fcmenin \u00e7al\u0131\u015fmaya devam etmesini sa\u011flar.<\/p>\n
kubectl nedir ve ne i\u015fe yarar?<\/h3>\n
kubectl<\/code>, Kubernetes k\u00fcmenizi komut sat\u0131r\u0131ndan y\u00f6netmek i\u00e7in kullan\u0131lan bir CLI (Komut Sat\u0131r\u0131 Aray\u00fcz\u00fc) arac\u0131d\u0131r. Pod'lar\u0131 da\u011f\u0131tmak, servisleri y\u00f6netmek, k\u00fcme kaynaklar\u0131n\u0131 g\u00f6r\u00fcnt\u00fclemek ve k\u00fcme durumunu kontrol etmek gibi bir\u00e7ok i\u015flemi kubectl<\/code> ile yapabilirsiniz.<\/p>\nKubernetes'te \"namespace\" ne anlama gelir?<\/h3>\n
Namespace'ler, Kubernetes k\u00fcmesi i\u00e7indeki kaynaklar\u0131 (Pod'lar, Service'ler, Deployment'lar vb.) mant\u0131ksal olarak izole etmek i\u00e7in kullan\u0131lan sanal k\u00fcmelerdir. B\u00fcy\u00fck projelerde veya birden fazla ekibin \u00e7al\u0131\u015ft\u0131\u011f\u0131 ortamlarda kaynak \u00e7ak\u0131\u015fmalar\u0131n\u0131 \u00f6nlemek ve y\u00f6netimi kolayla\u015ft\u0131rmak i\u00e7in kullan\u0131l\u0131rlar.<\/p>\n
Kubernetes'i \u00f6\u011frenmeye nereden ba\u015flamal\u0131y\u0131m?<\/h3>\n
Kubernetes'i \u00f6\u011frenmeye ba\u015flamak i\u00e7in \u00f6ncelikle konteyner (\u00f6zellikle Docker) kavram\u0131n\u0131 iyi anlamak \u00f6nemlidir. Ard\u0131ndan, Kubernetes'in temel mimarisini ve Pod, Deployment, Service gibi ana nesnelerini \u00f6\u011frenmekle ba\u015flayabilirsiniz. Minikube veya Kind gibi yerel k\u00fcme ara\u00e7lar\u0131, pratik yapmak i\u00e7in harika ba\u015flang\u0131\u00e7 noktalar\u0131d\u0131r. Resmi Kubernetes dok\u00fcmantasyonu ve \u00e7evrimi\u00e7i kurslar da de\u011ferli kaynaklard\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"G\u00fcn\u00fcm\u00fcz\u00fcn h\u0131zla de\u011fi\u015fen dijital d\u00fcnyas\u0131nda, uygulamalar\u0131 h\u0131zl\u0131, esnek ve g\u00fcvenilir bir \u015fekilde da\u011f\u0131tmak ve y\u00f6netmek b\u00fcy\u00fck \u00f6nem ta\u015f\u0131makt…","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_page_header_type":"","csco_page_load_nextpost":"","csco_page_subscribe_form":"","csco_page_contact_form":"","footnotes":""},"categories":[1491],"tags":[],"class_list":{"0":"post-37567","1":"post","2":"type-post","3":"status-publish","4":"format-standard","6":"category-kubernetes","7":"cs-entry","8":"cs-video-wrap"},"yoast_head":"\n
