apt 上的 DNS 不能在 docker 容器中工作，其他的工作
我的一台在 Debian 10 上執行 OMV 5 的伺服器上的 Docker 容器存在這個問題。
Temporary failure resolving關於這個設置。我最近在兩台 x86 和一台 ARM 伺服器上安裝了 OMV 5。問題僅出現在其中一台伺服器上，而在主機 os dns 內部似乎工作正常，我可以安裝和升級軟體包，在 docker 容器中它根本不起作用。我嘗試遵循幾個指南，到目前為止沒有任何幫助。還恢復了圖像並重新安裝了幾次docker。此外，伺服器具有相同的作業系統映像，只是與磁碟相關的一些配置更改。我試過這個指南https://development.robinwinslow.uk/2016/06/23/fix-docker-networking-dns/和這個https://www.dedoimedo.com/computers/docker-container-no- network.html 在所有伺服器上我都得到了這個

They have been ignored, or old ones used instead.我的路由器正在執行 OpenWrt 19.07，我還重新啟動它並刪除了 dhcp 租約。解決了安裝後無法自動配置網路的問題。我還找到並啟動了一個帶有 X 和 VNC 的容器。在瀏覽器中，DNS 可以正常工作，但在 apt 中卻不行。
我還使用 henet 隧道代理來獲取 ipv6。
該問題與 OMV 如何安裝 docker 和 portainer 預設接收網關 IP 的某種錯誤有關。重新創建不帶搬運工的 docker 儲存解決了這個問題。
