Tuzak 2: image prune -a<\/code> bekledi\u011finizden fazlas\u0131n\u0131 siler<\/h2>\n
“Kullan\u0131lmayan imaj”, \u015fu anda bir container’a ba\u011fl\u0131 olmayan<\/em> imaj demektir. Test ortam\u0131m\u0131zda docker image prune -a -f<\/code> \u00e7al\u0131\u015ft\u0131rd\u0131\u011f\u0131m\u0131zda, \u00fczerinde \u00e7al\u0131\u015fan container olmayan temel imaj\u0131m\u0131z da dahil her \u015fey<\/strong> silindi:<\/p>\n

Bu, bir CI sunucusunda ya da bir geli\u015ftirme makinesinde sonraki build’lerin t\u00fcm temel imajlar\u0131 ba\u015ftan indirmesi anlam\u0131na gelir. Yaln\u0131zca “bir haftadan eski” olanlar\u0131 temizlemek i\u00e7in filtre kullan\u0131n:<\/p>\n
docker image prune -a --filter \"until=168h\"<\/code><\/pre>\n
Etiketsiz (dangling) imaj nedir?<\/h2>\n
Ayn\u0131 etiketle yeni bir imaj build etti\u011finizde eski imaj etiketini kaybeder ve <none><\/code> olarak g\u00f6r\u00fcn\u00fcr. Bu imajlar hi\u00e7bir \u015feye ba\u011fl\u0131 olmad\u0131\u011f\u0131ndan docker image prune<\/code> (-a<\/code> olmadan) g\u00fcvenle siler. Listelemek i\u00e7in:<\/p>\n
docker images -f dangling=true<\/code><\/pre>\n
Not: Kendi denememizde (containerd imaj deposu kullanan Docker 29.4) ayn\u0131 etiketi yeniden build ettikten sonra dangling=true<\/code> listesi bo\u015f geldi; containerd deposunda etiketsiz imajlar eski depodan farkl\u0131 davranabilir. Ger\u00e7ek durumdan emin olmak i\u00e7in tahmin y\u00fcr\u00fctmek yerine docker system df<\/code>‘deki RECLAIMABLE de\u011ferine g\u00fcvenin.<\/p>\n
