Docker Machine Nedir?<\/h2>\n

Docker Machine, Docker Engine’i \u00e7e\u015fitli sanal makineler (VM’ler) \u00fczerinde kurmak i\u00e7in kullan\u0131lan bir ara\u00e7t\u0131r. Bu VM’ler yerel bilgisayar\u0131n\u0131zda (VirtualBox gibi), bir bulut sa\u011flay\u0131c\u0131s\u0131nda (AWS, Azure, DigitalOcean, Google Cloud) veya \u015firket i\u00e7i bir veri merkezinde olabilir. Docker Machine’in temel amac\u0131, Docker hostlar\u0131n\u0131 tek bir CLI aray\u00fcz\u00fcnden kolayca olu\u015fturup y\u00f6neterek Docker ortamlar\u0131n\u0131n karma\u015f\u0131kl\u0131\u011f\u0131n\u0131 azaltmakt\u0131r.<\/p>\n

Docker Machine, “s\u00fcr\u00fcc\u00fcler” (drivers) ad\u0131 verilen eklentiler arac\u0131l\u0131\u011f\u0131yla farkl\u0131 altyap\u0131 sa\u011flay\u0131c\u0131lar\u0131yla ileti\u015fim kurar. Her s\u00fcr\u00fcc\u00fc, belirli bir sanalla\u015ft\u0131rma veya bulut platformuyla etkile\u015fim kurmak i\u00e7in gerekli mant\u0131\u011f\u0131 i\u00e7erir. \u00d6rne\u011fin, virtualbox<\/code> s\u00fcr\u00fcc\u00fcs\u00fc yerel VirtualBox VM’lerini y\u00f6netirken, digitalocean<\/code> s\u00fcr\u00fcc\u00fcs\u00fc DigitalOcean droplet’lar\u0131n\u0131 y\u00f6netir. generic<\/code> s\u00fcr\u00fcc\u00fcs\u00fc ise zaten mevcut olan herhangi bir sunucuya (SSH eri\u015fimi olan) ba\u011flanarak Docker’\u0131 kurup yap\u0131land\u0131rman\u0131z\u0131 sa\u011flar.<\/p>\n

Docker Machine, bir host olu\u015fturdu\u011funda, o host \u00fczerine otomatik olarak Docker Engine’i kurar, gerekli TLS sertifikalar\u0131n\u0131 olu\u015fturur ve bunlar\u0131 yerel makinenize kopyalar. Bu sertifikalar, yerel Docker CLI’n\u0131z\u0131n uzak host ile g\u00fcvenli bir \u015fekilde ileti\u015fim kurmas\u0131n\u0131 sa\u011flar. B\u00f6ylece, docker<\/code> komutlar\u0131n\u0131 yerel makinenizden \u00e7al\u0131\u015ft\u0131rd\u0131\u011f\u0131n\u0131zda, asl\u0131nda uzak bir Docker hostundaki Docker daemon’\u0131 ile etkile\u015fim kurmu\u015f olursunuz.<\/p>\n

\n* API Eri\u015fim Bilgileri (Bulut Sa\u011flay\u0131c\u0131lar\u0131 \u0130\u00e7in):<\/strong> E\u011fer bir bulut sa\u011flay\u0131c\u0131s\u0131 (\u00f6rne\u011fin DigitalOcean, AWS) \u00fczerinde host olu\u015fturacaksan\u0131z, o sa\u011flay\u0131c\u0131n\u0131n API anahtar\u0131na veya kimlik bilgilerine ihtiyac\u0131n\u0131z olacakt\u0131r.
