docker 创建nginx容器时对配置文件进行挂载时报错，有那大佬热心提点提点！感谢感谢！！！！

Question

docker 以及 ngixn镜像信息如下：

root@iZ28q62x60iZ:/srv/testServer# docker -v
Docker version 18.03.1-ce, build 9ee9f40
root@iZ28q62x60iZ:/srv/testServer# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              649dcb69b782        19 hours ago        109MB
root@iZ28q62x60iZ:/srv/testServer# 

执行错误报如下错误：

第一条命令，docker 拼错了。

第二条命令的报错信息很明显:

$PWD/conf/nginx.conf 是目录，而镜像中的 /etc/nginx/nginx.conf 是 regular file, volume mount 失败。

剩下怎么解决应该不用提示吧，该删删，该建建

建议仔细看下nginx镜像中配置文件的目录结构，比如 /etc/nginx/conf.d/, 如果只是增加 server block，不必修改默认设置
