我的一台在 Debian 10 上运行 OMV 5 的服务器上的 Docker 容器遇到了这个问题。
Temporary failure resolving
关于这个设置。我最近在两台 x86 和一台 ARM 服务器上安装了 OMV 5。问题仅出现在其中一台服务器上，而在主机操作系统内部 dns 似乎工作正常，我可以安装和升级软件包，但在 docker 容器中它根本不起作用。我尝试遵循几个指南，但到目前为止没有任何帮助。还恢复了镜像并重新安装了几次docker。此外，这些服务器具有相同的操作系统映像，只是进行了一些与磁盘相关的配置更改。我已经尝试过这个指南https://development.robinwinslow.uk/2016/06/23/fix-docker-networking-dns/和这个https://www.dedoimedo.com/computers/docker-container-no-network.html 在所有服务器上我都得到这个

它可以在两台服务器上运行（arm 和 x86）：

我的路由器运行的是 OpenWrt 19.07，我还重新启动它并删除 dhcp 租约。解决了安装后无法自动配置网络的问题。我还找到并启动了一个带有 X 和 VNC 的容器。在浏览器中 DNS 工作正常，但在 apt 中不行。
我还使用 henet 隧道代理来获取 ipv6。
答案1
该问题与 OMV 安装 docker 和 portainer 时默认接收网关 IP 的某种错误有关。重新创建没有 portainer 的 Docker 存储解决了这个问题。
