SFTP on Azure

SFTP is a very widely used protocol which many organizations use today for transferring files within their organization or across organizations. Creating a VM based SFTP is costly and high-maintenance. In absence of a fully managed service, this template will be a good workaround for a cost-effective SFTP solution in Azure which is backed by durable persistent storage. ACI service is very inexpensive and requires very little maintenance, while data is stored in Azure Files which is a fully managed SMB service in cloud.

Key Value Prop

  • Simple SFTP Creation
  • Persistent and Durable Storage
  • Cost efficient solution
  • No VM maintenance overhead
  • Fast to deploy

How-To create an on-demand SFTP Server with a new Azure Files persistent storage

How-To create an on-demand SFTP Server with an existing Azure Files persistent storage

Overview

This template demonstrates an on-demand SFTP server using an Azure Container Instance (ACI). It creates a Storage Account and a File Share via the Azure CLI using another ACI (based on the 101-aci-storage-file-share template also in this repository). This File Share is then mounted into the main ACI to provide persistent storage after the container is terminated.

Usage

Once deployed, connect to the public IP of the SFTP ACI and upload files; these files should be placed into the File Share. Once transfers are complete, stop the ACI and the files will remain accessible. You can delete/recreate the ACI and mount the same file share to copy more files.

Click on the container sftp-group

 

Copy the IP address from the container group

 

Open Filezilla and open File ?Site Manager and enter the IP, username and password that was originally added during creation

 

Upload a file

 

  1. The file appears in your file share
