docker - Docker-compose“没有这样的服务”

问题描述

我docker-compose up -d使用这个 docker-compose.yml 文件启动时出错：没有这样的服务：php-c

它曾经工作，我没有改变任何东西。与此同时，我也没有任何 docker 更新。

如果我删除container_name密钥，那么我会显示与自动生成的名称相同的错误。

我正在使用 wsl2 和 docker 20.10.8。

version: '3'

services:
    db:
        image: mysql:5.7
        container_name: db-c
        ports:
            - 3307:3306
        volumes:
            - "./.data/db:/var/lib/mysql"
        environment:
            MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
            MYSQL_DATABASE: ${MYSQL_DATABASE}
            MYSQL_USER: ${MYSQL_USER}
            MYSQL_PASSWORD: ${MYSQL_PASSWORD}

    php:
        build:
            context: php7-fpm
            args:
                TIMEZONE: ${TIMEZONE}
                username: ${username}
        container_name: php-c
        volumes:
            - ${SYMFONY_APP_PATH}:/var/www/symfony
            - ./logs/symfony/:/var/www/symfony/var/logs
        environment:
            - XDEBUG_REMOTE_HOST=host.docker.internal
            - PHP_IDE_CONFIG=serverName=symfony.local
        user: 1000:1000

    nginx:
        build: nginx
        container_name: nginx-c
        ports:
            - 80:80
        volumes_from:
            - php
        volumes:
            - ./logs/nginx/:/var/log/nginx

这是 Dockerfile。

当我使用重启时，这有效......我真的不明白发生了什么。

docker-compose restart

解决方案

我有同样的问题。
看来volumes_from配置是问题的根源。（可能是一个 docker-compose 错误）

替换volumes_from为volumes我做了诀窍。

尝试将以下内容用于您的 nginx 服务配置：

    nginx:
        build: nginx
        container_name: nginx-c
        ports:
            - 80:80
        volumes:
            - ${SYMFONY_APP_PATH}:/var/www/symfony
            - ./logs/symfony/:/var/www/symfony/var/logs
            - ./logs/nginx/:/var/log/nginx
