docker - 相同的docker配置与不同项目重复

Question

我有两个具有相同docker配置(docker-compose.yml)，但文件不同的不同项目。

├── a
│   ├── docker-compose.yml
│   └── Dockerfile
└── b
    ├── docker-compose.yml
    └── Dockerfile

如何为不同的项目构建具有相同名称的容器？如果我仅同时在一个项目上工作，我不想为每个项目想到新名称。

ERROR: for mysql  Cannot create container for service mysql: Conflict. The container name "/mysql" is already in use by container "90a84268d483ec2bd5cf0feb7ab1972384941ba255a671c0cfd2b4017ce90682". You have to remove (or rename) that container to be able to reuse that name.

Docker-compose.yml

version: '3'

services:
  nginx:
    image: nginx:stable-alpine
    container_name: nginx
    ports:
      - "8080:80"
    volumes:
      - ./src:/var/www/html
      - ./nginx/default.conf:/etc/nginx/conf.d/default.conf
    depends_on:
      - php
      - mysql
    networks:
      - laravel

  mysql:
    image: mysql:8.0.19
    container_name: mysql
    restart: unless-stopped
    tty: true
    ports:
      - "3306:3306"
    environment:
      MYSQL_DATABASE: homestead
      MYSQL_USER: homestead
      MYSQL_PASSWORD: secret
      MYSQL_ROOT_PASSWORD: secret
      SERVICE_TAGS: dev
      SERVICE_NAME: mysql
    networks:
      - laravel

  php:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: php
    volumes:
      - ./src:/var/www/html
    ports:
      - "9000:9000"
    networks:
      - laravel

Answer 1

不要覆盖container_name。
