docker常用命令

Docker pull/push image测试
制作要push到registry的镜像
#查看本地已有镜像
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
registry 2 cd57aad0bd45 3 days ago 224.5 MB
nginx 1.9 813e3731b203 3 weeks ago 133.9 MB
#为本地镜像打标签
$ docker tag registry:2 docker-registry.com/registry:2
$ docker tag nginx:1.9 docker-registry.com/nginx:1.9
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
registry 2 cd57aad0bd45 3 days ago 224.5 MB

六、CentOS 7安装Docker及常用命令
yum install docker #安装docker
sudo systemctl daemon-reload #启动docker-daemon
sudo systemctl restart docker #重启启动docker
systemctl start docker.service #启动docker
systemctl enable docker.service #docker开机启动
docker -v #查看docker版本
docker info #查看docker具体信息
docker pull centos #下载centos image
docker images #显示已有image
docker rmi imageid #删除image
sudo usermod -a -G docker wisely #非root用户使用
docker run -i -t centos /bin/bash #启动系统
docker stop $(docker ps -a -q) #停止所有容器
docker rm $(docker ps -a -q) #删除所有container
docker rmi $(docker images -q) #删除所有image
docker inspect container_name #查看容器信息
docker inspect container_name | grep IPAddress #查看当前容器ip地地址
docker attach --sig-proxy=false 304f5db405ec (按control +c 退出不停止容器)
