Docker无法在Google Cloud Compute上解析DNS

时间：2019-09-26 15:31:01

标签： docker google-cloud-platform

我已经在GCP Compute计算机上设置了Docker 18.09.4。我使用的步骤来自官方Docker文档：https://docs.docker.com/install/linux/docker-ce/ubuntu/（我使用了可以选择安装特定版本的Docker的步骤）。

我想控制守护程序，所以我修改了/etc/docker/daemon.json使其具有以下内容：

{
    "debug": true,
    "dns": ["8.8.8.8", "8.8.4.4" ],
    "iptables": false
}

现在，我尝试了以下命令：

  1. docker运行busybox nslookup google.com
  2. docker run --dns 8.8.8.8 busybox nslookup google.com

他们两个都给了我错误：

;; connection timed out; no servers could be reached

然后我尝试使用以下命令启动一个新的nginx容器：

docker run --name nginx -d nginx

之后，我已连接到它：

docker exec -ti nginx /bin/sh

我在容器内执行了以下命令，该命令给了我错误：

apt-get update
Err:1 http://deb.debian.org/debian buster InRelease                  
  Temporary failure resolving 'deb.debian.org'

出什么问题了？

1 个答案:

答案 0 :(得分：0)

我在Ubuntu 18.04上的GCP上复制了您的问题，发现您遵循的Docker文档基于Ubuntu，并且可以使其工作：

在GCP上安装实例

  • 在GCP控制台中，我创建了一个带有“ Ubuntu 18.04”图像的实例。您可以在“启动磁盘”类别下指定映像。默认情况下，所选图像将为Debian 9，请确保对其进行更改。您可以将所有其他设置保留为默认设置。
  • 创建实例并通过SSH进入实例。

在Ubuntu 18.04上进行Docker安装

  1. 现在安装Docker时，我遵循了您提供的相同文档： https://docs.docker.com/install/linux/docker-ce/ubuntu
  2. 设置存储库。确保安装指南中指示的所有必需软件包。您可以通过以下方式验证是否已全部安装：
    $ dpkg -l apt-transport-https ca-certificates curl gnupg-agent software-properties-common
  1. 添加提及的Docker官方GPG。
    $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
  1. 别忘了添加存储库：
    sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
  1. 现在要安装版本5：18.09.4：
    $ sudo apt-get update
    $ sudo apt-get install docker-ce=5:18.09.4~3-0~ubuntu-bionic docker-ce-cli=5:18.09.4~3-0~ubuntu-bionic containerd.io
  1. 验证它是否有效：
    $ sudo docker run hello-world

带有Busybox的Docker内部的DNS解析

  1. 我尝试复制您的相同错误，但收到“没有答案”错误：
    $ sudo docker run --dns 8.8.8.8 busybox nslookup google.com
    Server:         8.8.8.8
    Address:        8.8.8.8:53

    Non-authoritative answer:
    Name:   google.com
    Address: 216.58.206.14

    *** Can't find google.com: No answer
  1. 键入“ busybox ”会使用可用图像的最新版本。相反，我尝试使用其他版本，但效果很好：
    $ sudo docker run busybox:glibc nslookup google.com
    Server:         169.254.169.254
    Address:        169.254.169.254:53

    Non-authoritative answer:
    Name:   google.com
    Address: 216.58.208.46

    Non-authoritative answer:
    Name:   google.com
    Address: 2a00:1450:4001:81d::200e

    $ sudo docker run --dns 8.8.8.8 busybox:glibc nslookup google.com
    Server:         8.8.8.8
    Address:        8.8.8.8:53

    Non-authoritative answer:
    Name:   google.com
    Address: 172.217.16.174

    Non-authoritative answer:
    Name:   google.com
    Address: 2a00:1450:4001:821::200e
  1. 所以我认为我们可以确认这是图像版本的问题。您可以在以下链接上找到有关图像的更多信息： https://hub.docker.com/_/busybox?tab=description

希望这解决了您的一些疑问。
