nginx - 当我尝试在 docker-compose 上将 nginx 部署到 MinIO 时出错

问题描述

我正在尝试在 docker 桌面（Windows 版本）上创建一个容器。我的项目包含一些容器。

我需要创建一个容器来运行 MinIO 来模拟 S3 存储桶。我在官方上得到了 docker-compose 文件。

我的 docker-compose.yml是这样的：

services:
    rabbitmq:
        image: rabbitmq:3-management
        container_name: rabbitmq
        restart: always
        ports: 
            - 5672:5672
            - 15672:15672
        volumes: 
            - ./dados:/var/lib/rabbitmq/
        environment:
            - RABBITMQ_DEFAULT_USER=admin
            - RABBITMQ_DEFAULT_PASS=password
    minio1:
        image: minio/minio:RELEASE.2021-06-17T00-10-46Z
        hostname: minio1
        volumes:
            - ./dados/minios3/data1-1:/data1
            - ./dados/minios3/data1-2:/data2
        expose:
            - "9000"
        environment:
            MINIO_ROOT_USER: minio
            MINIO_ROOT_PASSWORD: minio123
        command: server http://minio{1...4}/data{1...2}
        healthcheck:
            test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
            interval: 30s
            timeout: 20s
            retries: 3
    nginx:
        image: nginx:1.19.2-alpine
        hostname: nginx
        volumes:
            - ./dados/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
        ports:
            - 9000:9000
        depends_on:
            - minio1

唯一的区别是我将卷路径更改为我的目录，脚本的其余部分来自官方文档。

当我运行docker-compose up -d命令时，所有容器都被创建，除了 Nginx。显示错误。

有人知道为什么会发生此错误以及如何解决？

解决方案

您不需要添加 Nginx 文件名：nginx.conf. 只要有它的路径：

修改这个：

        - ./dados/nginx/nginx.conf:/etc/nginx/nginx.conf:ro

至

        - ./dados/nginx/:/etc/nginx/

并确保两条路径都正确：

  • ./dados/nginx/
  • /etc/nginx/

这是我的，它可以正常工作并注意卷部分（它不适合 MINIO）

webserver:
    depends_on:
        - wordpress
    image: nginx:1.18.0-alpine
    container_name: webserver
    restart: unless-stopped
    ports:
        - "80:80"
    volumes:
        - ./html:/var/www/html
        - ./nginx:/etc/nginx/conf.d
    networks:
        - wp-network
