docker创建nginx镜像
1.docker仓库中搜索nginx镜像。
[root@localhost ~]# docker search nginx
2.下载nginx镜像，这里我们选择下载人数最多的镜像版本。
[root@localhost ~]# docker pull docker.io/nginx
3.查看nginx是否下到本地
[root@localhost ~]# docker images |grep -i nginx #-i 忽略字符大小写
4.基于本地nginx镜像启动nginx web服务
[root@localhost ~]# docker run -itd -p80:80 docker.io/nginx
# run 全新启动一台容器
# -i interactive交互模式
# -t tty打开一个终端
# -d daemon后台启动
# -p 开启DNAT映射，讲宿主机80端口映射至容器的80，用户访问宿主机的80，即是访问
容器的80
5.查看已启动nginx容器
[root@localhost ~]# docker ps
6.查看nginx容器的ip地址
[root@localhost ~]# docker inspect e9aedca5f8f4 |grep -i ipaddr|tail -1|awk -F" '{print $4}'
172.17.0.2
7.访问nginx容易中web服务
[root@localhost ~]# curl 172.17.0.2
