Setup Test Container sFTP Server

Using atmoz-sftp

Steps:

  1. Download the FileZilla Client from the official website.

  2. Set Up an SFTP Server:

  • Refer to this image to create and run an SFTP Server container from the docker hub: atmoz-sftp.

  • Generate an SSH key pair: Create a private key sftp_rsa and a public key sftp_rsa.pub. Store them in a directory, e.g., ~/Downloads/sftp/keys.

  • Pull the Docker image, docker pull atmoz/sftp.

  • Choose a hostname: use "foo" for the client and "19" as the port.

  1. Run the Docker Container:

Use the command below to start the docker container, mount the volumes to transfer the public key to the server, and share files between the localhost and Docker container:

docker run \
  -v ~/Downloads/sftp/keys/sftp_rsa.pub:/home/foo/.ssh/keys/sftp_rsa.pub:ro \
  -v ~/Downloads/share:/home/foo/share \
  -p 19:22 -d atmoz/sftp \
  foo::1001
  1. Configure FileZilla Client:

Start FileZilla Client: Go to File → Site Manager → My Sites (create a name) → General → Set the following:
Protocol: SFTP
Host: localhost
Port: 19
Logon type: Key file
User: foo
Key file: Browse and select the private key sftp_rsa
Click Connect

  1. Verify Connection:

You should see the message “Status: Directory listing of /share successful" in the FileZilla dashboard. The remote site /share folder should reflect the files from your local ~/Downloads/share folder.

  1. Troubleshooting:

If you encounter issues, use the following commands to check the status and logs of the Docker container:

docker ps
docker logs <CONTAINER ID>
