Preface
In 2022, I worked on a Google Cloud Professional Services funded project at a Google Cloud service partner company to modernize a client’s monolithic application to containers running in Anthos clusters on bare metal. The client had already broke the monolithic retail oriented application into microservices. The goal of the project was to deploy the microservices to a Google Cloud distributed edge product based on Anthos clusters on bare metal. The specifications from Google were 3 standalone clusters, edge profile, HA mode.
The name of the edge product was confidential and not publicly available on Google Cloud documentation but many large restaurant operators and retailers were using it.
Introduction
The code base of the confidential platform product isn’t available to share but the whole setup was based on Anthos clusters on bare metal. I want to show how to install Anthos clusters on bare metal using a single node on Ubuntu Linux KVM. The Google cloud documentation to install Anthos clusters on bare metal was not robust so I had to resolve error messages myself to keep installation going.
Installation
I shared the technical content in the bmctl-workspace github page. At the end of the installation and setup, you should see the following in the cloud console:

Running passmark benchmark software on a gcloud pod generated the following results. Keep in mind that the results are not testing the 2 vCPUs thoroughly as Kubernetes has processes like kube-apiserver to occupy about a quarter of both vCPUs constantly. Running benchmark software on a cluster with more vCPUs would make the result closer to a production environment. You’d want to adjust the resource limit on the pod to be less than the vCPUs and memory available.

Anthos cluster on bare metal’s pricing is about $50 a month on a pay as you go basis. If you want to save on cost, stop the KVM to avoid the charge.
