构建Docker基础镜像（ubuntu20.04+python3.9.10+pytorch-gpu-cuda11.8）

---

一、前置条件

1. 配置一下 ubuntu 的镜像源
2. 下载 python 安装包

1.创建 ubuntu 镜像源文件【sources.list】

内容如下

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

2.下载 python 安装包【Python-3.9.10.tgz】

访问官网下载页 https://www.python.org/downloads/release/python-3910/
下拉选择 Gzipped 包

二、构建方法

1.构建目录

|---baseIMG_ub2004py3910pytorchgpucuda118||-----python|		|-----Python-3.9.10.tgz||-----ubuntu|		|-----sources.list||-----Dockerfile

2.创建DockerFile

3.打包镜像

docker build -t ub2004py3910pytorchgpucuda118:latest .

ps：创建镜像名为 ub2004py3910pytorchgpucuda118 标签为 latest 的镜像，从当前路径下的 DockerFile 文件打包
