Then we give ubuntu mirror copy of the file into the python requirement.txt, then the corresponding installation according to the document library python
Copy the file to the docker container. First, find the container corresponding ID . Then execute the command
docker cp file path to the source file destination path
root @ zhf-maple: / home / zhf / Desktop # docker ps

root@zhf-maple:/home/zhf/桌面# docker cp /home/zhf/docker/requirement.txt f98b8e77182b:/home/software_requirement

Save image:
Docker ps -l to find the vessel last modification of the above mentioned id .

Then docker commit containers ID mirror name can generate mirroring
root@zhf-maple:/home/zhf/docker# docker commit f98b8e77182b maple412/ubuntu:test
sha256: bca747cf9c55617d802d9e1633c6d70149959caef49af9a44f6d0a4b840c6c96
At this point we will have to view mirror generated image
root@zhf-maple:/home/zhf/docker# docker images

通过docker login -u xx -p xx 登录docker后就可以上传就成功了
root@zhf-maple:/home/zhf/docker# docker push maple412/ubuntu:test
The push refers to repository [docker.io/maple412/ubuntu]

docker hub上也可以看到上传的镜像
对应的Dockerfile如下：
FROM ubuntu
WORKDIR /home/software_requirement
COPY ./requirement.txt /home/software_requirement
RUN apt-get update && apt-get install python3-pip --assume-yes
RUN pip3 install -r requirement.txt
这里有2点需要注意下：
1 这里的COPY命令，源路径要写相对路径。也就是requirement.txt相对于Dockerfile的位置，否则会提示找不到源路径位置
2 在使用apt-get install的时候会遇到如下错误，提示是否需要安装，然后自动退出

解决办法就是在命令最后加上--assume-yes
RUN apt-get update && apt-get install python3-pip --assume-yes
