How to upload files to S3 from AWS CLI with kms encryption?

Question

I want to upload files from the local machine to S3 with KMS encryption, I have been using the below commands:

  aws s3 cp /filepath s3://mybucket/filename --sse-kms-key-id <key id>

It shows the following error 

" error occurred: when calling the PutObject operation: Server Side Encryption with AWS KMS managed key requires HTTP header x-amz -server-side-encryption : aws:kms" 

What could possibly be causing this error?

Answer 1

It seems like you are missing the "--sse aws:kms" flag. You're likely looking for something like

aws s3 cp /filepath s3://mybucket/filename --sse aws:kms --sse-kms-key-id <key id>
