Rancher Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/h2>\r\n\r\n\r\n\r\n

Rancher uygulamas\u0131, d\u00fc\u015f\u00fcn\u00fcld\u00fc\u011f\u00fcn\u00fcn aksine container y\u00f6netimini ba\u015fka uygulamalar gibi tek ba\u015f\u0131na yapm\u0131yor. Uygulama \u00e7al\u0131\u015f\u0131rken arka plan\u0131nda ise ayr\u0131 olarak kubernetes uygulamas\u0131 \u00e7al\u0131\u015f\u0131yor. Yaz\u0131m\u0131z i\u00e7erisinde birden kez kubernetes kavram\u0131n\u0131 kulland\u0131k. Kubernetesi k\u0131saca anlatmak gerekirse, Google \u015firketi taraf\u0131ndan geli\u015ftirilmi\u015f ve\u00a0g\u00fcn\u00fcm\u00fczde de geli\u015ftirilmesi devam etmekte olan ve Docker container y\u00f6netimi i\u00e7in temel olarak kabul edilen ara\u00e7t\u0131r. Asl\u0131na bakarsan\u0131z Rancher kurmadan Kubernetes kurulumu ve y\u00f6netimi ile ayn\u0131 i\u015fleri yapabilirsiniz. Rancher, Kubernetes sisteminin bir \u00fcst seviyesinde bulunuyor. K\u0131saca anlatmak gerekirse, Rancher vas\u0131tas\u0131yla kubernetes kurulumlar\u0131 ger\u00e7ekle\u015ftirerek Kubernetes gibi uzmanl\u0131k gerektiren \u00e7ok geli\u015fmi\u015f bir arac\u0131n karma\u015f\u0131kl\u0131\u011f\u0131yla u\u011fra\u015fm\u0131yoruz.

RancherOS Nedir?<\/h2>\r\n\r\n\r\n\r\n

RancherOS, Rancher Labs \u015firketi taraf\u0131ndan bulut teknolojilerinde kullan\u0131lmak amac\u0131yla geli\u015ftirilmi\u015f bir i\u015fletim sistemidir. Bu i\u015fletim sistemi daha farkl\u0131 boyutlarda incelendi\u011finde, sistemin ba\u015flamas\u0131n\u0131 sa\u011flayan ve ayr\u0131ca y\u00f6neten bir Linux \u00e7ekirde\u011fi ile Docker oldu\u011funu g\u00f6receksiniz. Yani burada anlatmak istedi\u011fimiz husus, Linux \u00e7ekirde\u011finin g\u00f6revinin Docker sistemini ba\u015flatmak oldu\u011funu belirtmek. Linux \u00e7ekirde\u011fi Docker sistemini ba\u015flatt\u0131\u011f\u0131 s\u0131rada, bu t\u00fcm sistem birer Docker konteyner\u0131ndan olu\u015fmaktad\u0131r, bu sayede sistem olabildi\u011fi kadar sade ve hafif bir Linux da\u011f\u0131t\u0131m\u0131 olarak kullan\u0131c\u0131lara sunulmaktad\u0131r.<\/p>\r\n\r\n\r\n\r\n

Docker\u2019\u0131n ba\u015flang\u0131\u00e7ta \u00e7al\u0131\u015fma prensibi d\u0131\u015f\u0131nda sistem i\u00e7in gerekli olan t\u00fcm bile\u015fenler konteyner mant\u0131\u011f\u0131yla \u00e7al\u0131\u015f\u0131r. Bu\u00a0olduk\u00e7a \u00f6nemli bir \u00f6zelliktir. Bu \u00f6zelli\u011fi sisteme kolayl\u0131k ve ciddi bir esneklik kazand\u0131r\u0131r. RancherOS bu durumlar\u0131ndan \u00f6t\u00fcr\u00fc di\u011ferlerinden h\u0131zl\u0131ca yar\u0131l\u0131r. RancherOS\u2019un esnek ve minimalist tasar\u0131m\u0131 sald\u0131r\u0131 risklerini ciddi bir oranda azalt\u0131r, donan\u0131m ve bak\u0131m gibi uzun vade \u00fczerinden d\u00fc\u015f\u00fcn\u00fcld\u00fc\u011f\u00fcnde sorun te\u015fkil edebilecek olan maliyetlerini ise olduk\u00e7a d\u00fc\u015f\u00fcr\u00fcr. Yine bahsetti\u011fimiz ayn\u0131 tasar\u0131m, RancherOS\u2019u konteyner sistemleri i\u00e7erisinde muadilleri ile k\u0131yasland\u0131\u011f\u0131 zaman, ideal bir Linux da\u011f\u0131t\u0131m\u0131 olmas\u0131n\u0131 sa\u011flamaktad\u0131r.<\/p>\r\n\r\n\r\n\r\n

RancherOs i\u015fletim sistemi \u00fczerinde 2 adet Docker instance\u2019\u0131 \u00e7al\u0131\u015ft\u0131rmaktad\u0131r. Bunlardan ilk olan\u0131 ise Sistem Docker\u2019\u0131d\u0131r. Syslog, ntpd, Konsol gibi hizmetler Sistem Docker\u2019\u0131 ile birlikte olduklar\u0131 zaman konteyner \u00fczerinden \u00e7al\u0131\u015f\u0131r. Sistem Docker\u2019\u0131n \u00f6zelli\u011fi bununla s\u0131n\u0131rl\u0131 de\u011fil. Sistem Docker\u2019\u0131 ayn\u0131 zamanda RancherOS\u2019da \u00e7al\u0131\u015fan ilk process (s\u00fcre\u00e7) dir. Bu s\u00fcre\u00e7 denilen durumda, di\u011fer bilindik pek \u00e7ok Linux da\u011f\u0131t\u0131m\u0131nda da bulunan systemd\u2019nin g\u00f6revini yerine getirmektedir. Sistem Docker\u2019\u0131, i\u015flem yapt\u0131\u011f\u0131 di\u011fer konteynerlar\u0131n yan\u0131nda docker ismiyle bir tane daha Docker konteyner ba\u015flat\u0131l\u0131r ve bu ortam\u0131n y\u00f6netimini yapar. Bu tasar\u0131m\u0131n di\u011fer yaz\u0131l\u0131mlara g\u00f6re daha iyi olan soyutlama becerisi sayesinde RancherOS, daha g\u00fcvenli ve stabil hale gelmi\u015ftir.<\/p>\r\n\r\n\r\n\r\n

Son olarak Rancher uygulamas\u0131n\u0131 sizlere \u00f6zetlemek gerekirse Kubernetes kullan\u0131m\u0131n\u0131 \u00e7ok fazla uzmanl\u0131k gerektirmeden, son kullan\u0131c\u0131n\u0131nda her zaman anlayaca\u011f\u0131 \u015fekilde kullan\u0131m sa\u011flar. Kullanma seviyesi basite indirgenerek container y\u00f6netimini daha kolay yapmam\u0131z\u0131 sa\u011flar. Son derece modern bir sanalla\u015ft\u0131rma uygulamalar\u0131ndan biridir. Rancher, Swarm ve Docker Cloud gibi uygulamalardan daha geni\u015f \u00f6l\u00e7ekli y\u00f6netim ve kurulum yapmam\u0131z\u0131 sa\u011flar. Bu alanda \u00e7\u0131kacak son uygulama diyemeyiz i\u00e7in. Ancak bu konuya ilgisi olan yada bu uygulamalar\u0131 kullanacak olanlar\u0131n incelemesinde b\u00fcy\u00fck bir fayda var. Gelece\u011fin internet ve bulut hizmetler \u00fczerinden y\u00f6nlenece\u011fimizi d\u00fc\u015f\u00fcnd\u00fc\u011f\u00fcm\u00fczde, Rancher gibi uygulamalar herkese gelecek vadetme potansiyeli ta\u015f\u0131maktad\u0131rlar.<\/p>\r\n","protected":false},"excerpt":{"rendered":"Rancher kelimesini k\u0131saca de\u011finecek olursak, container y\u00f6netimini kolayl\u0131kla yapmam\u0131z\u0131 sa\u011flayan bir ara\u00e7t\u0131r.
