进入nginx 容器

[root@localhost ~]# docker exec -it nginx01 /bin/bash

root@c573c2624534:/# whereis nginx 查看nginx的配置文件，配置文件在/etc/nginx

root@c573c2624534:/# cd /etc/nginx/

root@c573c2624534:/etc/nginx# ls 查看nginx 配置文件

conf.d  fastcgi_params  mime.types  modules  nginx.conf  scgi_params  uwsgi_params

root@c573c2624534:/etc/nginx#

退出nginx 容器

root@c573c2624534:/etc/nginx# exit
exit
[root@localhost ~]# docker ps 查看

官方使用 docker run -it --rm tomact :9.0
#我们之前的启动都是后台启动，停止了容器，容器还是可以查到，docker run -it --rm .用来测试。用完就删除
