Dockerhub organizations delete inactive image

Merhaba, bu makalede dockerhub organizasyon hesabınızda kullanılmayan eski imajları belirlediğiniz gün sayısı kadar tutup, otomatik olarak kullanılmayan inactive imajları silmeyi hedefleyeceğiz,

Dockerhub’ı eğer Organizasyon olarak kullanıyorsanız (örnek veriyorum musteri-php) reposu içerisinde (212) kadar aktif olmayan imaj olmadığına dair bildirim gözünüze ilişmiştir,

Bu işlem için; dockerhub’un api’lerini kullanarak örneğin 50 gündür kulanılmayan inactive imajları silebiliyoruz,

              ## Please uncomment below line to delete docker hub images of docker hub repositories

           fi

done

echo "Script execution ends"

Yukarıdaki bash scriptte kullanıcı adı, şifre ve yetkili olduğunuz organizasyonu en başta belirleyerek 50 gün geriye doğru inactive imajlarınızı silebilirsiniz.
