docker 安装操作

1.安装docker服务，配置镜像加速器
 

安装软件包

[root@bogon ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
设置yum源
[root@bogon ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
安装
[root@bogon ~]# yum list docker-ce --showduplicates | sort -r
[root@bogon ~]# yum -y install docker-ce-18.03.1.ce
启动docker设置开机自启
[root@bogon ~]# systemctl enable --now docker
配置镜像加速器
[root@bogon ~]# mkdir -p /etc/docker
[root@bogon ~]# tee /etc/docker/daemon.josn <<- 'EOF'
> {
>  "registry-mirrors": ["https://09s7n5di.mirror.aliyuncs.com" ]
> }
> EOF

2.下载系统镜像（Ubuntu、 centos）

[root@bogon ~]# docker pull ubuntu
[root@bogon ~]# docker pull centos
[root@bogon ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
ubuntu              latest              ba6acccedd29        22 months ago       72.8MB
centos              latest              5d0da3dc9764        23 months ago       231MB

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@bogon ~]# docker run --name longsiqi -it ubuntu /bin/bash
root@dca8744849ff:/# exit
exit
[root@bogon ~]# docker run --name LSQ -it centos /bin/bash
[root@05ca7fc065c9 /]# exit
exit
[root@bogon ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
05ca7fc065c9        centos              "/bin/bash"              18 seconds ago      Exited (0) 9 seconds ago                        LSQ
dca8744849ff        ubuntu              "/bin/bash"              3 minutes ago       Exited (0) 2 minutes ago                        longsiqi

4.容器的启动、 停止及重启操作

[root@bogon ~]# docker start LSQ
LSQ
[root@bogon ~]# docker stop LSQ
LSQ
[root@bogon ~]# docker restart LSQ
LSQ

5.怎么查看正在运行的容器和所有容器？

[root@bogon ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
05ca7fc065c9        centos              "/bin/bash"         5 minutes ago       Up About a minute                       LSQ
[root@bogon ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
05ca7fc065c9        centos              "/bin/bash"              6 minutes ago       Up About a minute                               LSQ
dca8744849ff        ubuntu              "/bin/bash"              9 minutes ago       Exited (0) 8 minutes ago                        longsiqi
b76ab0ae0e34        nginx               "/docker-entrypoint.…"   26 minutes ago      Exited (0) 23 minutes ago                       sad_goldwasser

6.怎么退出容器： 两种方法分别实现？

exit ctrl+p+Q
7.怎么连接到运行的容器？

[root@bogon ~]# docker exec -it LSQ /bin/bash
[root@05ca7fc065c9 /]# 

8.查看容器或镜像的内部信息？

[root@bogon ~]# docker inspect LSQ | grep -i address
            "LinkLocalIPv6Address": "",
            "SecondaryIPAddresses": null,
            "SecondaryIPv6Addresses": null,
            "GlobalIPv6Address": "",
            "IPAddress": "172.17.0.2",
            "MacAddress": "02:42:ac:11:00:02",
                    "IPAddress": "172.17.0.2",
                    "GlobalIPv6Address": "",
                    "MacAddress": "02:42:ac:11:00:02",

9.如何查看所有镜像？

[root@bogon ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              eea7b3dcba7e        6 days ago          187MB
ubuntu              latest              ba6acccedd29        22 months ago       72.8MB
centos              latest              5d0da3dc9764        23 months ago       231MB
