安装Docker和下载images镜像和常用Docker命令

安装Docker和下载images镜像和常用Docker命令

 

 

我的是centos7的方法：

$sudo yum install docker   直接yum安装contos7
使用centos6.5先获取epel源并

启动Docker，并注册开机服务
[root@iZ258c9w799Z ~]# sudo service docker start
Redirecting to /bin/systemctl start  docker.service
[root@iZ258c9w799Z ~]# sudo chkconfig docker on
Note: Forwarding request to 'systemctl enable docker.service'.
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
//查看是否启动

[root@iZ258c9w799Z ~]# ps -ef|grep docker
root 12584 1 0 11:33 ? 00:00:00 /bin/sh -c /usr/bin/docker-current daemon $OPTIONS $DOCKER_STORAGE_OPTIONS $DOCKER_NETWORK_OPTIONS $ADD_REGISTRY $BLOCK_REGISTRY $INSECURE_REGISTRY 2>&1 | /usr/bin/forward-journald -tag docker
root 12585 12584 0 11:33 ? 00:00:00 /usr/bin/docker-current daemon --selinux-enabled
root 12586 12584 0 11:33 ? 00:00:00 /usr/bin/forward-journald -tag docker
root 12705 12448 0 11:34 pts/0 00:00:00 grep --color=auto docker

下载images镜像，现在下载基础的contos镜像：

[root@iZ258c9w799Z ~]# sudo docker pull centos:7
Trying to pull repository docker.io/library/centos ... 7: Pulling from library/centos

Status: Downloaded newer image for docker.io/centos:7

查看是否安装成功：

[root@iZ258c9w799Z ~]# sudo docker images centos
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

可以去docker下载你需要的镜像：https://hub.docker.com/

常用docker命令：

1、docker -h 帮助
2、获取镜像
sudo docker pull NAME[:TAG]
sudo docker pull centos:latest
3、启动Container盒子
sudo docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
sudp docker run -t -i contos /bin/bash
4、查看镜像列表，列出本地的所有images
sudo docker images [OPTIONS] [NAME]
sudo docker images centos
5、查看容器列表，可看到我们创建过的所有container
sudo docker ps [OPTIONS]
sudo docker ps -a
6、删除镜像，从本地删除一个已经下载的镜像
sudo docker rmi IMAGE [IMAGE...]
sudo docker rmi centos:latest
7、移除一个或多个容器实例
sudo docker rm [OPTIONS] CONTAINER [CONTAINER...]
移除所有微运行的容器
sudo docker rm sudo docker ps -aq
8、停止一个正在运行的容器
sudo docker kill [OPTIONS] CONTAINER [CONTAINNER...]
sudo docker kill 026e
9、重启一个正在运行的容器
sudo docker restart [OPTIONS] contains[CONTAINER]
sudo docker restart 026e
10、停止一个已经停止的容器
sudo docker start [OPTIONS] CONTAINER [CONTAINER..]
sudo docker start 026e
