How to Create a MySql Instance with Docker Compose

trouble

 docker-compose up -d

FROM php:7.1-fpm-alpine
Run apt-get update \
&& apt install iputils-ping \
&& docker-php-ext-install mysqli && docker-php-ext-enable mysqli

这些单词 拼写 我去 ，



定义网络叫app_net 写在应用又写了d_net 


		container_name: "compose-php"
	mysql:
		image: mysql:8.0
		ports:
			- "3306:3306"
		environment:
			- MYSQL_ROOT_PASSWORD={your_passwd}
		networks:
			- d_net
		container_name: "compose-mysql"
networks: 			#配置docker 网络
