我正在使用 Prisma 和 Docker 和 MySQL 设置本地开发。我在使用 MySQL 版本 8 设置环境时遇到问题。下面是我的docker-compose文件
version: ‘3.7’
services:
prisma:
image: prismagraphql/prisma:1.19
restart: always
ports:
- “4466:4466”
depends_on:
- mysql
environment:
PRISMA_CONFIG: |
port: 4466
# uncomment the next line and provide the env var PRISMA_MANAGEMENT_API_SECRET=my-secret to activate cluster security
# managementApiSecret: my-secret
databases:
default:
connector: mysql
host: mysql
port: 3306
user: root
password: prisma
migrations: true
mysql:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
ports:
- “3306:3306”
environment:
MYSQL_ROOT_PASSWORD: prisma
volumes:
- mysql:/var/lib/mysql
volumes:
mysql:
但是 Prisma 似乎无法连接到 MySQL 数据库。以下是错误（安装程序在 MySQL 5.7 和 PostgresSQL 上运行良好）：
Exception in thread “main” java.sql.SQLTransientConnectionException: database - Connection is not available, request timed out after 5002ms.
