使用Docker Compose部署Nginx，创建docker-compose.yaml：
[root@192 ~]# vim docker-compose.yaml
输入以下内容：
version: '3'
services:
nginx:
container_name: nginx
image: nginx
restart: always
ports:
- 8080:80
privileged: true
networks:
- mynginx
networks:
mynginx:
driver: bridge
基于docker-compose.yaml创建并启动容器：
[root@192 ~]# docker compose up

关闭防火墙：
[root@192 ~]# systemctl stop firewalld
本地浏览器可以访问，说明Nginx部署成功了。
Docker也可以查到Docker Compose拉取的镜像和创建的容器。
[root@192 ~]# docker images
