Docker serverless.yml不在本地创建dynamodb表

我有一个docker设置，在docker中运行serverless和dynamodb。在我的serverless.yml中，我定义了创建表的指令，但是当我运行

docker compose up

时，它不会创建表（我通过运行查询来列出表进行了检查）

npm run start

只需离线运行

sls

。运行docker compose后，一切都会正常启动，但不会创建

UserTable

如果您使用Docker管理DynamoDB服务，则需要指示

无服务器DynamoDB local

插件为您创建表

您可以通过运行以下命令来执行此操作：

无服务器dynamodb迁移

Docker版本的DynamoDB local的一个常见问题是，只有使用用于创建表的相同AWS访问密钥ID的客户端才能看到表，例如运行

list tables

时，即使已成功创建表，也不会显示任何表

$aws dynamodb列表表--端点”http://localhost:8000"
{
“表名”：[]
}

最简单的解决方案可能是将

-sharedDb

选项传递给DynamoDB：

docker-run-p8000:8000-d amazon/dynamodb local-jar DynamoDBLocal.jar-sharedDb

然后在运行

无服务器dynamodb migrate

后生成预期输出：

aws dynamodb列表表--端点”http://localhost:8000"
{
“表格名称”：[
“采样可测局部”
]
}
