Hello team, I want to install lakeFS on AWS. I followed the instructions you provided here, where I created an IAM with the DynamoDB permissions you specified. I linked this IAM to a new EC2 instance, created the

config.yaml

and ran the

lakefs

command. However, I get an error:

WARNING[2024-10-23T09:07:01Z]lakeFS/pkg/kv/dynamodb/store.go:199 pkg/kv/dynamodb.setupKeyValueDatabase Failed to create or detect KV table           error="operation error DynamoDB: CreateTable, https response error StatusCode: 0, RequestID: , request send failed, Post \"<https://dynamodb>..<http://amazonaws.com/\|amazonaws.com/\>": dial tcp: lookup dynamodb..<http://amazonaws.com|amazonaws.com>: no such host" table_name=kvstore

I wanted to ask if you can reproduce it and help me resolve this? Thanks in advance!

Hey @Benoit Putzeys 👋 There seems to be something wrong with your DDB host, the region part of the url is missing (for example

<http://dynamodb.us-east-1.amazonaws.com|dynamodb.us-east-1.amazonaws.com>

). Could you double check your lakeFS config and/or your AWS env vars on the EC2 instance and make sure there’s no some sort of mixup?

Hey Itai. Thank you very much for your quick reply! This helped because now I get a different error (yay) haha

FATAL  [2024-10-23T09:59:37Z]lakeFS/cmd/lakefs/cmd/run.go:165 cmd/lakefs/cmd.init.func9 Failure on schema validation                  error="get KV schema version: get item: operation error DynamoDB: GetItem, https response error StatusCode: 400, RequestID: JARDBF7599AP7Q40IJIAAGCJ3NVV4KQNSO5AEMVJF66Q9ASUAAJG, api error ValidationException: The provided key element does not match the schema"

Now I'm not so sure 😅 are you using a fresh DDB table? Is it possible that are some leftovers in the table you use?

ah I thought I had deleted it but indeed it was still there!
