笔记：

1.拉取ubuntu镜像并运行

docker pull ubuntu
docker run -it ubuntu bash

2.先添加阿里云的源,编辑文件/etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

apt-get update

3.添加nginx的源并安装
apt-get install curl gnupg2 ca-certificates lsb-release
echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" | tee /etc/apt/sources.list.d/nginx.list
curl -fsSL https://nginx.org/keys/nginx_signing.key | apt-key add -
apt-key fingerprint ABF5BD827BD9BF62
apt-get update
apt-get install nginx
