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 "[email protected]"
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
