docker history --format {{.CreatedBy}} --no-trunc=true $DockerImage |sed "s//bin/sh\ -c\ #(nop)\ //g"|sed "s//bin/sh\ -c/RUN/g" | tac

kubectl get nodes
kubectl get services

docker build -t mynginx .

docker run -it --name xxx -v /root/xxx/:/workspace -p 8081:80 xxx/xxx
docker exec -it xxx /bin/bash

docker ps -a
docker images
docker image ls

docker run -it image_name
docker exec -it container_name

docker search centos

docker load -i mynginx.tar

docker export vs import (容器导出为tar VS tar导入为镜像)
docker export -o ubuntu.tar f6f212ca3017
docker export -o export_xxx.tar 21c38d724788

docker import ubuntu.tar myubuntu #基于容器导出的tar构建镜像

docker commit (merge save/load/export/import) 使用容器创建镜像
docker commit e7856417a422 tesseract_xxx
docker save -o tesseract_xxx.tar tesseract_xxx

docker run -d -p 5555:22 --name tessxxx --privileged=true centos /usr/sbin/init
docker run --rm tesseract_xxx xxx -v

docker network ls
docker get nodes
docker get services
