Dockerfile 无法构建

Question

直到几天前 Dockerfile工作正常，当我今天再次尝试构建它时，它在终端中出现以下错误。我尝试了多个 docker 基础镜像，但仍然出现相同的错误。谁能帮我这个？我不认为我错过了任何东西。如果我错过了它应该早点给我错误，但为什么现在？

我的 docker 版本是 Docker version 17.03.2-ce, build f5ec1e2
这是我的 Dockerfile

FROM ubuntu:16.04

ARG DEBIAN_FRONTEND=noninteractive

RUN apt-get update -y && \
    apt-get install -y software-properties-common && \
    apt-add-repository ppa:webupd8team/java && \

如果您的主机是 Ubuntu VM，则它可能是无效的 /etc/resolve.conf .看/etc/resolv.conf在主机 Ubuntu VM 上。如果包含 nameserver 127.0.1.1 ， 那是错的。

在主机 Ubuntu VM 上运行这些命令来修复它:

sudo vi /etc/NetworkManager/NetworkManager.conf
# Comment out the line `dns=dnsmasq` with a `#`

# restart the network manager service
sudo systemctl restart network-manager

cat /etc/resolv.conf

现在 /etc/resolv.conf nameserver 应该有一个有效的值，它将被 docker 容器复制。
