1.安装docker服务,配置镜像加速器
1)、环境
#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 '[email protected]@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 - Community Version: 24.0.5 API version: 1.43 Go version: go1.20.6 Git commit: ced0996 Built: Fri Jul 21 20:39:02 2023 OS/Arch: linux/amd64 Context: default Server: Docker Engine - Community Engine: Version: 24.0.5 API version: 1.43 (minimum version 1.12) Go version: go1.20.6 Git commit: a61e2b4 Built: Fri Jul 21 20:38:05 2023 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.6.22 GitCommit: 8165feabfdfe38c65b599c4993d227328c231fca runc: Version: 1.1.8 GitCommit: v1.1.8-0-g82f18fe docker-init: Version: 0.19.0 GitCommit: de40ad0
2.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
3.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 wp -it ubuntu root@987276383c38:/# exit exit \[root@localhost \~\]# docker run --name wangp -it centos:7 \[root@8223d6f2e3e7 /\]# exit exit
4.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
5.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
6.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
7.怎么连接到运行的容器?
root@localhost \~\]# docker exec -it wangp /bin/bash \[root@8b8d60576bac /\]#
8.查看容器或镜像的内部信息?
[root@localhost ~]# docker inspect wangp
9.如何查看所有镜像?
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
