Question

我是新来的Docker, 现在我要使用 spateie/laravel- backup 软件包来备份我的工程和数据库。

我需要在 Php 容器内运行 mysqldump 命令

当我在DB容器内运行 mysqldump 命令时,我可以适当地使用它,但在Php容器内找不到这个命令。

这是我的docker-compact.yml :

version:  2 

services:
  project-db:
    image: mariadb:10.3.35
    container_name: project-db
    volumes:
      - ./.configs/mysql_data:/var/lib/mysql
    ports:
      - "3309:3306"
    env_file:
      - ./.configs/.env.setup

  project-nginx:
    image: nginx:stable
    container_name: project-nginx
    volumes:
      - ./workspace/project/:/var/www/project/
      - ./.configs/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
    ports:
      - "80:80"
    links:
      - project-php

  project-php:
    build: .
    container_name: project-php
    volumes:
      - ./workspace/project/:/var/www/project/
      - ./.configs/php/php-ini-overrides.ini:/etc/php/7.4/fpm/conf.d/99-overrides.ini
    links:
      - project-db

Answer 1

您正在使用 building:. 在您的 project-php 服务中使用 building:. 。

我猜你有 Dockerfiles , 尝试添加 :

RUN apt-get update 
    && apt-get install -y default-mysql-client

或

如果您正在使用 alpine 基于图像, 请添加 :

RUN apk add --no-cache mariadb-client

这将在您的 PHP 容器上安装 < code> mysqldump 。

在您的服务旁边使用 network 。这样, 您的容器将在同一网络上, 并且能够“ 连接 ” 。
