1-更新镜像源：

需要 mkdir config

cat > config/sources.list  <<'EOF'
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
# deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
EOF

2- 编写 Dockerfile

FROM ubuntu:20.04
​
​
LABEL maintainer=baimeidashu


​
COPY config/sources.list /etc/apt/sources.list
​

其他镜像：

FROM registry.cn-hangzhou.aliyuncs.com/baimeidashu/ubuntu:20.04

MAINTAINER zhaozhiyong  "715740383@qq.com"
COPY config/sources.list /etc/apt/sources.list

RUN apt-get update

阿里云： cat build.sh

#!/bin/bash

imagename=ubuntu20.4-aliyuan:v1.
docker build -t registry.cn-hangzhou.aliyuncs.com/kattgatt-base/$imagename --no-cache -f Dockerfile . --progress=plain
docker push registry.cn-hangzhou.aliyuncs.com/kattgatt-base/$imagename

registry.cn-hangzhou.aliyuncs.com/kattgatt-base/ubuntu20.4-aliyuan:v1.0
