一、安装docker服务,配置镜像加速器
1.环境搭建
#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
[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
[root@localhost ~]# yum makecache fast
[root@localhost ~]# yum -y install docker-ce 
4.配置docker镜像加速
[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
[root@localhost ~]# docker version
Client: Docker Engine - CommunityVersion:           24.0.5API version:       1.43Go version:        go1.20.6Git commit:        ced0996Built:             Fri Jul 21 20:39:02 2023OS/Arch:           linux/amd64Context:           defaultServer: Docker Engine - CommunityEngine:Version:          24.0.5API version:      1.43 (minimum version 1.12)Go version:       go1.20.6Git commit:       a61e2b4Built:            Fri Jul 21 20:38:05 2023OS/Arch:          linux/amd64Experimental:     falsecontainerd:Version:          1.6.22GitCommit:        8165feabfdfe38c65b599c4993d227328c231fcarunc:Version:          1.1.8GitCommit:        v1.1.8-0-g82f18fedocker-init:Version:          0.19.0GitCommit:        de40ad0 
二、下载系统镜像(Ubuntu、 centos)
[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)
[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
#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?
#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?
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?
[root@localhost ~]# docker exec -it wangp /bin/bash
[root@8b8d60576bac /]#  
八、查看容器或镜像的内部信息?
[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
