命令汇总
docker history fa5
fa5为镜像id或者镜像名
docker export 30b >h.tar
30b为容器id或者容器名
# docker export angry_bell > angry_bell.tar
# docker export --output=angry_bell-latest.tar angry_bell
# ls -sh angry_bell.tar
321M angry_bell.tar
# ls -sh angry_bell-latest.tar
321M angry_bell-latest.tar
docker import
与export是相反的
docker version
docker images -a
docker ps -a
docker top c94
docker stats c94 30b
docker port c94
列出端口映射，c94为容器id或者容器名
docker info
docker inspect
inspect vi. 进行检查；进行视察,vt. 检查；视察；检阅
docker logs c94
在A主机上操作
docker export 30b > htt.tar
docker save 192.168.1.22:5000/man > man.tar
scp man.tar 192.168.1.220:/root/
在B主机上操作
docker load --input man.tar
docker images -a
docker ps -a
docker info
docker rm container-id
docker rmi image-id
私服
yum install docker
docker ps
docker exec 0ae ls /usr/local/apache2/htdocs
docker exec 0ae cat /usr/local/apache2/htdocs/index.html
docker cp pycharm-community-2016.1.2.tar.gz 0ae:/usr/local/apache2/htdocs/
docker cp index.html 0ae:/usr/local/apache2/htdocs/
docker commit 0ae httpd-a
docker tag httpd-a localhost:5000/httpd-a
docker push localhost:5000/httpd-a
客户端
yum install docker
docker pull 192.168.1.22:5000/httpd-a
docker run -d -p 7965:80 192.168.1.22:5000/httpd-a
c/s本地与远程访问
vi /etc/sysconfig/docker
要使远程可以访问就加入-H 0.0.0.0:5555监听端口，否则就只能本地访问。
要本地与远程同时可以访问就加入-H 0.0.0.0:5555和-H unix:///var/run/docker.sock。
OPTIONS='-H 0.0.0.0:5555 --registry-mirror=http://a984be05.m.daocloud.io --selinux-enabled'
docker -H 192.168.1.22:5555 images
docker -H 192.168.1.22:5555 ps
While the docker commit command is a convenient way of extending an existing image, you should prefer the use of a Dockerfile and docker build for
generating images that you intend to share with other people.

docker export import save load
export 与 save出来的格式是不一样的
在A主机上操作 docker export 30b > htt.tar docker save 192.168.1.22:5000/man > man.tar scp man.tar 192.168.1.220:/root/ 在B主机上操作 docker load --input man.tar
