Transfer files

Use secure copy (SCP) from the command line to transfer files to Google Distributed Cloud air-gapped appliance virtual machine (VM) instances.

Before you begin

Important: You must already have access management enabled to proceed. If you do not, follow the steps in Guest environment. By default, access management is enabled.

You need the following to use the SCP command-line tool to transfer files to VMs:

• You must manually manage your SSH keys.
• You must enable ingress on port 22 for your VM. See the Enable IP addresses page for more information.

The SCP tool uses the same key files that you use to connect to your instances using standard SSH.

Important: If you haven't yet applied a public key to your VM instance, create an SSH key pair and add the public key to the VM following the instructions in Linux (SSH).

Transfer files to VMs

Locate the external IP address for the VM to which you want to send files using the instructions on the Enable IP addresses page.

Use the SCP tool to copy a file from your workstation to the home directory of the target VM in the following example, which uses a private key at ~/.ssh/my-ssh-key:

scp -i ~/.ssh/my-ssh-key LOCAL_FILE_PATH USERNAME@IP_ADDRESS:~

Use the following definitions for your variables.

Variable	Definition
LOCAL_FILE_PATH	The name of the local file that you want to upload.
USERNAME	Your username.
IP_ADDRESS	The VM's external ingress IP address.

Transfer files from a VM

To copy files from a VM to your local workstation, reverse the source and destination variables. The following example shows how to copy a file from your VM to a path on your workstation:

scp -i ~/.ssh/my-ssh-key USERNAME@IP_ADDRESS:REMOTE_FILE_PATH LOCAL_FILE_PATH

Use the following definitions for your variables.

Variable	Definition
USERNAME	Your username.
IP_ADDRESS	The VM's external ingress IP address.
REMOTE_FILE_PATH	The name of the remote file that you want to download.
LOCAL_FILE_PATH	The location on your workstation to which you want to download the file.
