Google Cloud Platform
This guide provides step-by-step instructions for deploying a VyOS instance with two NICs and the required resources on Google Cloud Platform (GCP).
Prerequisites
Before proceeding, ensure the following:
A GCP account with billing enabled.
Permissions to deploy Marketplace images.
Access to enable APIs and create resources (e.g., Compute Engine Admin, Network Admin).
An SSH key pair for VyOS instance access.
GA Google Cloud Project.
Deployment Steps
Step 1: Add SSH Key
If you don’t already have SSH keys, generate an SSH key pair of type
ssh-rsa
on your local machine:
Example:
ssh-keygen -t rsa -f ~/.ssh/vyos_gcp -C "vyos@mypc"
Note
In the comment vyos@mypc
, the username must start with vyos.
This is because the default user in the VyOS image is vyos
, and the Google Cloud API uses this value for SSH access.
Open GCP console and navigate to the Compute Engine > Metadata > SSH Keys. Choose SSH Keys.

Click edit and Add item.
Paste your public ssh key and Save.

For more information, please visit the official Google Cloud documentation:
https://cloud.google.com/compute/docs/connect/add-ssh-keys
https://cloud.google.com/compute/docs/connect/create-ssh-keys
Step 2: Create a Service Account (If You Don’t Have One)
In the Google Cloud console IAM & Admin > Service Accounts.
Select select a project.

Click Create Service Account:
Name: e.g.,
vyos-test
Service account ID: e.g.,
vyos-test
Description: e.g.,
VyOS Test Service Account
Click Done.

For more information, please visit the official Google Cloud documentation:
Step 3: Create VPC Networks and Subnets
In the Google Cloud console VPC Network > VPC Networks https://console.cloud.google.com/networking/networks/list
Select select a project.

Click Create VPC Network.
Public VPC:
Name: e.g.,
vyos-public-vpc
Subnet creation mode:
Custom
Subnet name: e.g.,
vyos-public-subnet
Region: e.g.,
europe-west1
IP range: e.g.,
10.0.1.0/24
Leave all other settings at default, then click Create.


Private VPC:
Name:
vyos-private-vpc
Subnet creation mode:
Custom
Subnet name:
vyos-private-subnet
Region: e.g.,
europe-west1
IP range:
10.0.11.0/24
Leave all other settings at default, then click Create.


Add firewall rules to allow specific network traffic from the Internet. By default all incoming traffic from outside a network is blocked.

https://cloud.google.com/vpc/docs/create-modify-vpc-networks
Step 4: Deploy VyOS instance from Marketplace
Go to the Google Cloud Marketplace page in the Google Cloud console https://console.cloud.google.com/marketplace
Choose the project where you want to deploy the VyOS instance.

In the search bar, type
vyos
to find the VyOS image in the Marketplace.


On the next page, review details such as support, pricing, and other details.

Click the
GET STARTED
button to start deployment process.


General settings.
Deployment name: e.g.,
vyos-test-vm
Select a Service Account: Select the service account created earlier.
Image: Select VyOS image for deployment.
Zone: e.g.,
europe-west1-b
Machine type: Choose based on performance and resource needs.


Configure the network interfaces.
Public Network interface:
Edit the first (default) network interface and select following settings:
Network:
vyos-public-vpc
Subnetwork:
vyos-public-subnet
External IP:
Ephemeral
Private Network interface:
Private Network Interface:
Click ADD A NETWORK INTERFACE button to create a second (private) interface, and select following settings:
Network:
vyos-private-vpc
Subnetwork:
vyos-private-subnet
External IP:
None

Deployment automation.
You can use
cloud-init
User Data
to automatically inject specific configuration commands into the VyOS instance during deployment.Example:
#cloud-config vyos_config_commands: - set system host-name 'VyOS-for-GCP' - set system login banner pre-login 'Welcome to the VyOS for on GCP' - set interfaces ethernet eth0 description 'WAN' - set interfaces ethernet eth1 description 'LAN' - set interfaces ethernet eth1 address 'dhcp' - set interfaces ethernet eth1 dhcp-options no-default-route
For more information, please visit the official VyOS documentation:
https://docs.vyos.io/en/stable/automation/cloud-init.html#module-vyos-userdata

Click
Deploy
button.


Connect to the VyOS instance
To connect to the VyOS instance, use the SSH key that was generated in the first step.
To retrieve the public IP address, go to the Google Cloud Console and navigate to: Compute Engine > VM instances https://console.cloud.google.com/compute/instances?project=vyos-images

Example:
ssh [email protected] -i .ssh/vyos_gcp The authenticity of host '35.233.97.132 (35.233.97.132)' can't be established. ED25519 key fingerprint is SHA256:KCsCnwCGhwX2ba5RcPUAO3ZUSNzS4sXIkujFoScCd0g. This key is not known by any other names Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added '35.233.97.132' (ED25519) to the list of known hosts.
