I mean, I have to know the ID? I cannot get a resource just from its name?

@limited-rainbow-51650 Although I need to get a DataSource and a DynamoDB table, according to the doc there is no

.getInstance(...)

for AWS DataSources and DynamoDB tables Pulumi types. Right?

@limited-rainbow-51650 For Appsync DataSource I see a

.get(...)

function but it seems it requires an ID: https://www.pulumi.com/registry/packages/aws/api-docs/appsync/datasource/

I couldn’t find any ARN or ID for AppSync DataSource in AWS.

In that case I might just recreate another DataSource and associate it with the same existing DynamoDB table.

I figured it out thanks to the help of @limited-rainbow-51650. If that can be of any help to someone else, this is how you get an existing AWS DynamoDB table from its name (in Python). You need to do it in two steps. The documentation is not clear on that and on what is an ID (blink to Pulumi’s team, would be great to improve the doc on that points) Here you are (I type-hinted the vars for more clarity):

import pulumi_aws as aws


dynamodb_table_info: aws.dynamodb.get_table.AwaitableGetTableResult = aws.dynamodb.get_table(name="my-name")

dynamodb_table: aws.dynamodb.Table = aws.dynamodb.Table.get(resource_name=dynamodb_table_info.name, id=dynamodb_table_info.id)
