docker 引导 docker tutorial

1 install docker

wget -qO- https://get.docker.com/ | sh  ##docker 安装

systemctl enable  docker

systemctl start  docker

2 本地docker 仓库搭建

docker pull registry

mkdir -p /data/registry

docker run -itd -v /data/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry      registry:latest

curl http://127.0.0.1:5000/v2/_catalog

3 基础镜像·拉取

docker pull  centos

docker images

4 根据拉取的镜像，运行容器  以准备镜像环境测定 docker run

docker run -d -it --privileged --name centos-test centos /usr/sbin/init /bin/bash -c 'tail -f /tmp/null'

5 docker ps -a

进入容器： docker exec -it  `docker ps  | grep nginx | awk '{print $1}'` /bin/bash

docker cp Python-3.7.0a1.tar.xz f3a159f3c3a8:/root

#docker rm -f

6 提交 docker images

docker ps | grep centos

#提交信息 -a  author -m commit docker_id  imagine_name

docker commit -a "test" -m "test" 0ea857a05646 test:001

docker tag test:001 127.0.0.1:5000/test:001

docker push 127.0.0.1:5000/test:001
