1.问题描述

当基于dockerfile创建容器时，遇到Could not connect to ...、Failed to fetch ...等异常时，大概原因是没有配置好容器创建所需的镜像源。这里以Ubuntu基础镜像源为例。

  • dockerfile内容
bash 复制代码 
FROM ubuntu
RUN apt update && apt install python3 -y && apt install python3-pip -y && apt install git -y && apt install vim -y && apt install curl -y && apt install wget -y && apt install unzip -y && apt install zip -y && apt install tree -y && apt install npm -y
CMD ["bash"]
  • dockerfile执行与异常提示
bash 复制代码 
$ docker build -f data/dockerfiles --tag my_test

2.解决方案

本质上，是需要修改基于镜像文件创建的容器中的/etc/apt/sources.list文件，将该文件中的镜像源从官方源换成国内源。这里以Ubuntu基础镜像源为例，有如下两种可选方案实施。

2.1.从dockerfile添加命令修改（自动化、简单）

打开dockerfile，在FROM ...命令后添加镜像源修改命令即可，如下：

bash 复制代码 
FROM ubuntu
# 镜像源修改命令
RUN sed -i "s@http://.*archive.ubuntu.com@http://mirrors.tools.aliyun.com@g" /etc/apt/sources.list
RUN sed -i "s@http://.*security.ubuntu.com@http://mirrors.tools.aliyun.com@g" /etc/apt/sources.list
# 容器软件安装命令
RUN apt update && apt install python3 -y && apt install python3-pip -y && apt install git -y && apt install vim -y && apt install curl -y && apt install wget -y && apt install unzip -y && apt install zip -y && apt install tree -y && apt install npm -y
CMD ["bash"]

添加镜像源修改命令后，再次执行容器构建命令docker build -f data/dockerfiles --tag my_test，即可快速完成容器构建。

2.2.从创建启动的基础镜像容器修改（略微繁琐）

  • （1）创建启动基础镜像的容器

    bash 复制代码 
    $ docker run -it ubuntu /bin/bash

  • （2）进入容器命令行，然后手动修改sources.list文件

    shell 复制代码 
    $ vim /etc/apt/sources.list

# 官方sources.list文件内容
deb http://archive.ubuntu.com/ubuntu/ bionic main restricted
deb-src http://archive.ubuntu.com/ubuntu/ bionic main restricted
deb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted
deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted
deb http://archive.ubuntu.com/ubuntu/ bionic universe
deb-src http://archive.ubuntu.com/ubuntu/ bionic universe
deb http://archive.ubuntu.com/ubuntu/ bionic-updates universe
deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates universe
deb http://archive.ubuntu.com/ubuntu/ bionic multiverse
deb-src http://archive.ubuntu.com/ubuntu/ bionic multiverse
deb http://archive.ubuntu.com/ubuntu/ bionic-updates multiverse
deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates multiverse
deb http://archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ bionic-security main restricted
deb-src http://security.ubuntu.com/ubuntu/ bionic-security main restricted
deb http://security.ubuntu.com/ubuntu/ bionic-security universe
deb-src http://security.ubuntu.com/ubuntu/ bionic-security universe
deb http://security.ubuntu.com/ubuntu/ bionic-security multiverse
deb-src http://security.ubuntu.com/ubuntu/ bionic-security multiverse

    将上述官方sources.list文件内容修改为如下：

    sehll 复制代码 
    deb http://mirrors.tools.aliyun.com/ubuntu bionic main restricted
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic main restricted
deb http://mirrors.tools.aliyun.com/ubuntu bionic-updates main restricted
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-updates main restricted
deb http://mirrors.tools.aliyun.com/ubuntu bionic universe
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic universe
deb http://mirrors.tools.aliyun.com/ubuntu bionic-updates universe
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-updates universe
deb http://mirrors.tools.aliyun.com/ubuntu bionic multiverse
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic multiverse
deb http://mirrors.tools.aliyun.com/ubuntu bionic-updates multiverse
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-updates multiverse
deb http://mirrors.tools.aliyun.com/ubuntu bionic-backports main restricted universe multiverse
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-backports main restricted universe multiverse
deb http://mirrors.tools.aliyun.com/ubuntu bionic-security main restricted
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-security main restricted
deb http://mirrors.tools.aliyun.com/ubuntu bionic-security universe
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-security universe
deb http://mirrors.tools.aliyun.com/ubuntu bionic-security multiverse
deb-src http://mirrors.tools.aliyun.com/ubuntu bionic-security multiverse

    注意，重要事情说3遍：
    该步骤一定是在启动的基础镜像容器内部执行！！！

  • （3）在当前容器中，手动安装dockerfile中列出的其他软件包

    bash 复制代码 
    apt update && apt install python3 -y && apt install python3-pip -y && apt install git -y && apt install vim -y && apt install curl -y && apt install wget -y && apt install unzip -y && apt install zip -y && apt install tree -y && apt install npm -y
