Running Local SFTP server

To test code related to SFTP servers locally, it is useful to spin up a local container that acts as SFTP server. atmoz/sftp and sftpgo are two such popular containerized solution options.

What follows below is a quick set of instructions to get you started using the sftpgo library. More detailed instructions can be found here.

• Generate a public/private key pair

ssh-keygen -t rsa -b 4096 -f ssh_host_rsa_key < /dev/null

• Launch an sftpgo container. Notice we are binding a local path on the host to the sftp server to simulate a file system. sh docker run --name some-sftpgo -p 127.0.0.1:8080:8080 -p 2022:2022 --mount type=bind,source=/Users/bajal/share,target=/outbox -d "drakkan/sftpgo:latest"
• Go to localhost:8080 and setup a user. Copy the public key generated in step 1 here. Password could be left blank.

• Now you can connect to the server using the private key created in step 1 as:

sftp -v -P 2022 -i ssh_host_rsa_key foo@localhost
