| - | If you need to access/manage files stored on Amazon S3 (Simple Storage Service) bucket via SFTP, you can mount the bucket to a file system on a Linux server and access the files using the SFTP as any other files on the server. | + | //Note that WinSCP supports a [[guide_amazon_s3|direct access to S3 storage]]//. |
| - | This guide shows how to mount the S3 bucket using ''[[https://github.com/s3fs-fuse/s3fs-fuse|s3fs]]'' file system to an Amazon EC2 server and access it using WinSCP. | + | If you need to access/manage files stored on Amazon S3 (Simple Storage Service) bucket via SFTP, there are two options. You can use a native managed SFTP service recently added by Amazon (which is easier to set up). Or you can mount the bucket to a file system on a Linux server and access the files using the SFTP as any other files on the server (which gives you greater control). |

| - | A basic Amazon Linux AMI (free tier eligible) server will generally suffice and the following instructions are tested on this distribution. Instructions for other distributions may differ. | + | ==== Creating Managed SFTP Server ==== |
| - | ===== Installing s3fs ===== | + | * To create a Managed SFTP server for S3, in your Amazon AWS Console, go to [[https://console.aws.amazon.com/transfer|AWS Transfer for SFTP]] and create a new server (you can keep server options to their defaults for a start). |
| + | * In SFTP server page, add a new SFTP user (or users). | ||
| + | * Permissions of users are governed by an associated [[https://console.aws.amazon.com/iamv2/#/roles|AWS role]] in IAM service. To create a role which has a full access to all your S3 buckets, just create an //S3// service role with //AmazonS3FullAccess// policy. \\ The role must have trust relationship to ''transfer.amazonaws.com''. On a role page, select //Trust relationships// tab, click //Edit trust relationship// button, and in the access control policy JSON document, change ''Statement[].Principal.Service'' value to ''transfer.amazonaws.com'':((Based on the answer by @ChristopherTull to [[https://stackoverflow.com/q/53642132/850848#53648926|Connecting to AWS Transfer for SFTP]] on Stack Overflow.)) \\ <code php> | ||
