已排查情况 #

• 已在Docker Compose中配置-sharedDb参数并指定数据存储路径
• 应用仅修改了DynamoDB的URL，其他配置在生产/测试环境可正常运行
• 使用技术栈：Node.js 16 + Dynamoose

解决建议 #

1. 确认本地实例中是否存在目标表 #

通过aws-cli连接本地DynamoDB，列出所有表：

aws dynamodb list-tables --endpoint-url http://localhost:8000

若未查询到目标表，需手动创建或检查应用的表初始化逻辑是否正常执行。

2. 验证Dynamoose的本地实例配置 #

确保Dynamoose明确指向本地端点，且配置了本地所需的占位凭证：

const dynamoose = require('dynamoose');
// 本地DynamoDB无需真实凭证，配置占位值即可
dynamoose.aws.sdk.config.update({
  accessKeyId: 'dummy-key',
  secretAccessKey: 'dummy-secret',
  region: 'us-east-1'
});
// 指定本地DynamoDB端点
dynamoose.aws.ddb.local('http://localhost:8000');

3. 检查数据卷的挂载与权限 #

• 验证容器内数据目录的权限与内容：

docker exec local-db ls -l /home/dynamodblocal/

• 若权限异常或旧数据卷存在脏数据，可删除旧卷后重新启动：

docker-compose down -v
docker-compose up -d

4. 确认应用表初始化时机 #

若依赖Dynamoose自动创建表，需确保模型配置中开启自动创建与等待表就绪：

const UserSchema = new dynamoose.Schema({ /* 表结构定义 */ });
const UserModel = dynamoose.model('User', UserSchema, {
  create: true, // 开启自动创建表
  waitForActive: true // 等待表创建完成再执行后续操作
});

5. 验证-sharedDb参数是否生效 #

进入容器检查进程启动命令，确认-sharedDb参数已正确加载：

docker exec local-db ps aux

若参数未出现在进程命令中，需检查Docker Compose的command格式是否正确（注意参数顺序与空格）。
