This is used to practice terraform to create AWS resources and uploaded tfstate files to S3
How to set up OpenID Connect for AWS. Remember to set up the necessary permissions depending on which AWS services used, otherwise your GitHub Actions workflow will fail
Retrieving object from S3 can be done either way with s3api get-object or s3 cp
aws s3api get-object --bucket bucket/name --key path/to/object downloaded/object
aws s3 cp s3-URI downloaded/object
Since I used base64 to encode before uploading to S3, I had to decode with base64 after I retrieved the S3 object
base64 -d downloaded/object > decoded/file
