docker exec -it xxx sh  //进入容器
docker container run -it busybox sh
ip a //查看地址
docker container top 31 //查看容器的进程
ps aux|grep nginx //查看进程

docker 镜像

docker image pull nginx
docker pull nginx:1.20.0

dockerfile基本结构

FROM ubuntu:20.04
RUN apt-get update && \
    DEBIAN_FRONTEND=noninteractive apt-get install --no-install-recommends -y python3.9 python3-pip python3.9-dev
ADD hello.py /
CMD ["python3", "/hello.py"]
//开始构建
docker image build -t hello:1.1 .  
docker run -it hello:1.1
docker image rm xiaopeng163/hello:1.0
docker image tag hello:1.1  wanlf/hello:1.0  //改名字

docker镜像上传

docker login    #id password
docker image push 
docker image push 781776053/hello:1.0   //tag名字要和账号对应
docker image pull  781776053/hello:1.0
docker run -it 781776053/hello:1.0
docker container commit 884 781776053/hello:1.0  //通过容器创建对象
docker container run -it 781776053/hello:1.0  python3 /hello.py
