分享docker container抛出错误：php_network_getaddresses：getaddrinfo failed：名称或服务未知
请检查我的docker-compose文件：
version: '2'
services:
db:
image: mysql:latest
networks:
app_net:
ipv4_address: 172.16.238.10
ipv6_address: 2001:3984:3989::10
volumes:
- "./data/db:/var/lib/mysql"
restart: always
environment:
MYSQL_ROOT_PASSWORD: wordpress
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
wordpress:
image: wordpress
links:
- db
ports:
- "8000:80"
environment:
- WORDPRESS_DB_PASSWORD=wordpress
networks:
app_net:
ipv4_address: 172.16.238.12
ipv6_address: 2001:3984:3989::10
volumes:
- ./code:/code
- ./html:/var/www/html
networks:
app_net:
driver: bridge
driver_opts:
com.docker.network.enable_ipv6: "true"
ipam:
driver: default
config:
- subnet: 172.16.238.0/24
gateway: 172.16.238.1
- subnet: 2001:3984:3989::/64
gateway: 2001:3984:3989::1
现在两个容器正在运行：
正确配置了两个容器的IP地址.但是当我连接到http://172.16.238.12:8000/(172.16.238.12 – 是wordpress的IP地址)时.它说,“无法连接”.
当我检查docker_wordpress_1的日志文件时,它显示我：
Warning: mysqli::mysqli(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known in - on line 10
MySQL Connection Error: (2002) php_network_getaddresses: getaddrinfo failed: Name or service not known
我不明白出了什么问题.

我看到你的’db’部分中没有任何端口映射. (使用相同的网络配置).我正在使用以下数据库部分,之后可以建立连接：
db:
build:
context: .
dockerfile: ./compose/mysql/Dockerfile
volumes:
- mysql_data_dev:/var/lib/mysql
restart: always
ports:
- "3306:3306"
container_name: typewriter_db
networks:
app_net:
ipv4_address: 172.16.238.10
ipv6_address: 2001:3984:3989::10
