arista cloudeos on Google Cloud Platform (GCP)

arista cloudeos is now supported on Google Cloud Platform (GCP), as well as other public and private clouds.

Overview

arista cloudeos

arista cloudeos is a cloud-grade and feature-rich virtual router for Google cloud. This software-only release of EOS software is supported on public clouds, as well as on customer premises equipment running Linux and VMware hypervisors. By bringing advanced network telemetry and secure IPSec VPN connectivity in a software-only package, cloudeos provides a consistent, secure and universal approach to hybrid cloud networking for any virtualized cloud deployment.

This release of cloudeos is available as a software subscription in Google Cloud Launcher following a BYOL and PAYG license model. For BYOL instance, a cloudeos license activation key must be obtained separately from arista, which unlocks the platform from a default performance limit of 10 Mbps, and enable the use of IPsec encrypted VPNs. For PAYG instance, the license will be installed by the system automatically so customers can start using all features including IPsec and uncapped throughput. For more information about licensing, please refer to Chatper 2 - License Management.

Deploying arista cloudeos on GCP

  1. Locate the cloudeos listing in the Google Cloud Launcher, then select LAUNCH ON COMPUTE ENGINE.

  2. Fill out the relevant fields in the deployment screen, then select Deploy.

    Update zones, name and other details as needed. Also add user name with public SSH key for that user. You can also change the machine type depending upon the performance requirements of the VM and also add more than one NIC if needed.

    Note: When adding a SSH public key make sure you paste the key without any extra spaces and newlines. For example, the public key looks similar to this.

  3. After deployment, you will find the information about your cloudeos instance in the post deployment screen.

  1. From the post deployment screen select vm instance.
  2. Select MANAGE RESOURCE.
  3. Locate the External IP.
  4. Log into the instance using the credentials you entered during the deployment:
    “ssh -i <private_key_file> <username>@<external_ip>”.

cloudeos router Startup-Configuration using Instance Custom-Data

 

This section describes the use of custom-data during the initial deployment of the veos router instance, GCP provides an option to upload custom-data. The custom-data used passes in the configuration for multiple entities. Currently, GCP supports only the EOS configuration. This configuration is separated using start and end markers.

The administrator is allowed to upload veos router configuration using custom-data while launching a router instance through the portal as shown below. Note, the custom-data works only during the first boot.

Note, the following regarding the custom-data.

  • Markers must be at the beginning of the line.
  • The user is expected to have tested the configurations on a live system before using the configurations to deploy the new veos router. Mis-configuration may result in an unrecoverable instance.
  • EOS configuration for all interfaces is passed in during the deployment. The configuration takes effect as the new instances attach to the veos router.
