Docker Compose部署Nginx的方法步骤

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

后台up（防火墙需要先开启，不然会报错）：

[root@192 ~]# systemctl start firewalld
[root@192 ~]# docker compose up -d
[+] Running 1/1

关闭服务：

[root@192 ~]# docker compose stop nginx

 ⠿ Container nginx  Stopped

启动服务：

[root@192 ~]# docker compose start nginx
[+] Running 1/1
 ⠿ Container nginx  Started
