Mount S3 Bucket onto Linux Folder : s3FS : FUSE - Filesystem in Userspace

https://levelup.gitconnected.com/how-to-mount-s3-bucket-on-an-ec2-linux-instance-df44c7885aae

https://medium.com/tensult/aws-how-to-mount-s3-bucket-using-iam-role-on-ec2-linux-instance-ad2afd4513ef

S3FS

An S3 bucket can be mounted in an AWS instance as a file system known as S3fs. S3fs is a FUSE file system that allows you to mount an Amazon S3 bucket as a local file system.

Filesystem in Userspace (FUSE) is a simple interface for userspace programs to export a virtual file system to the Linux kernel.

• Install S3FS
• vim /etc/passwd-s3fs [Enter AccessKey/Secret Key of AWS having full S3 Permissions]
• Mount Bucket to a Linux Folder

          mkdir /mys3bucket

         s3fs your_bucketname -o use_cache=/tmp -o allow_other -o uid=1000 -o mp_umask=002 -o multireq_max=5 /mys3bucket
