My application running in EKS (AWS Kubernetes) is failing to access an S3 bucket.
I'm getting a 400 Bad Request errors in my app.
I suspect a permission is missing, so for testing I added arn:aws:iam::aws:policy/AmazonS3FullAccess to any role I could find related to my EKS cluster. Still failing.
Using an S3 client from my local computer, I can access the bucket so I suspect I'm missing some configuration.
Any ideas?
Ok... issue was resolved. I'm leaving this here for future reference.
The problem was a mismatch of the bucket region, us-west-2 and the endpoint I had configured in my application. It should have been s3.us-west-2.amazonaws.com.
The error returned by S3 was not clear.
I hope this helps others.
