Ubuntu 14.04 LTS'deki Docker konteynerlerimle ilgili bir sorunla karşılaşıyorum. Docker iki gün boyunca iyi çalıştı ve sonra birdenbire konteynerlerimdeki tüm ağ bağlantısını kaybettim. Aşağıdaki hata çıktısı, başlangıçta apt-get'in DNS'yi IPv6 aracılığıyla çözmeye çalıştığı için inanmamı sağladı.
Ana makinemde IPv6'yı devre dışı bıraktım ve hala tüm görüntüleri kaldırdım, taban ubuntunu çektim ve hala sorunla karşılaştım.
/Etc/resolve.conf nameservers'ımı yerel DNS sunucumdan Google'ın genel DNS sunucularına değiştirdim (8.8.8.8 ve 8.8.4.4) ve hala şansım olmadı. DNS’i / etc / default / docker ve yeniden başlatılan docker’ın DOCKER_OPTS’inde de Google’a ayarlıyorum.
Ayrıca coreos çekmeyi denedim ve yum DNS'yi de çözemedi.
Garip çünkü DNS çalışmazken, apt-get 'in çözemediği aynı güncelleme sunucularına ping işlemi yaparken hala bir yanıt alıyorum.
Proxy'nin arkasında değilim, çok standart bir yerel ağdayım ve Ubuntu'nun bu sürümü güncel ve yeni (docker'a daha yakın olmak için iki gün önce yükledim).
Bunu stackoverflow ve github konularındaki diğer yayınlar aracılığıyla iyice araştırdım, ancak herhangi bir çözüm bulamadım. Bu sorunun nasıl çözüleceğine dair fikirlerim dışında, biri yardımcı olabilir mi?
