一、安装docker服务,配置镜像加速器
1.环境搭建
bash
#服务器版本
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
#内核版本
[root@localhost ~]# uname -r
3.10.0-1160.el7.x86_64
2.添加并修改docker-ce源信息00
bash
[root@localhost ~]# yum install yum-utils device-mapper-persistent-data lvm2 -y
[root@localhost ~]# sed -i 's@download.docker.com@mirrors.tuna.tsinghua.edu.cn/docker-ce@g' /etc/yum.repos.d/docker-ce.repo
3.更新并安装docker-CE
bash
[root@localhost ~]# yum makecache fast
[root@localhost ~]# yum -y install docker-ce
4.配置docker镜像加速
bash
[root@localhost ~]# vim /etc/docker/daemon.json
{
"registry-mirrors":["http://hd1esep4.mirror.aliyuncs.com"]
}
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
5.查看docker版本
bash
[root@localhost ~]# docker version

二、下载系统镜像(Ubuntu、 centos)
bash
[root@localhost ~]# docker pull centos:7
7: Pulling from library/centos
2d473b07cdd5: Pull complete
Digest: sha256:9d4bcbbb213dfd745b58be38b13b996ebb5ac315fe75711bd618426a630e0987
Status: Downloaded newer image for centos:7
docker.io/library/centos:7
[root@localhost ~]# docker pull ubuntu
Using default tag: latest
latest: Pulling from library/ubuntu
7b1a6ab2e44d: Pull complete
Digest: sha256:626ffe58f6e7566e00254b638eb7e0f3b11d4da9675088f4781a50ae288f3322
Status: Downloaded newer image for ubuntu:latest
docker.io/library/ubuntu:latest
三、基于下载的镜像创建两个容器 (容器名一个为自己名字全拼,一个为首名字字母)
bash
[root@localhost ~]# docker run --name cyg -it ubuntu
root@987276383c38:/# exit
exit
[root@localhost ~]# docker run --name chenyonggui -it centos:7
[root@8223d6f2e3e7 /]# exit
exit
四、容器的启动、 停止及重启操作
bash
#启动命令
[root@localhost ~]# docker start wp
wp
#停止命令
[root@localhost ~]# docker stop wp
wp
#重启命令
[root@localhost ~]# docker restart wp
wp
五、怎么查看正在运行的容器和所有容器?
bash
#查看正在运行的容器
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
987276383c38 ubuntu "bash" 2 minutes ago Up 53 seconds wp
#查看所有容器
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8223d6f2e3e7 centos:7 "/bin/bash" 2 minutes ago Exited (0) 2 minutes ago wangp
987276383c38 ubuntu "bash" 3 minutes ago Up About a minute wp
六、怎么退出容器: 两种方法分别实现?
bash
1)、[root@localhost ~]# docker run --name wp -it ubuntu /bin/bash
root@08f0ad338d35:/# exit
exit
2)、ctrl(长按)+p+q
七、怎么连接到运行的容器?
bash
[root@localhost ~]# docker exec -it wangp /bin/bash
[root@8b8d60576bac /]#
八、查看容器或镜像的内部信息?
bash
[root@localhost ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu latest ba6acccedd29 22 months ago 72.8MB
centos 7 eeb6ee3f44bd 23 months ago 204MB
