Hi, while I’m trying to find a cheap hourly dedicated server I stumbled upon an option given by Vultr.com with their bare-metal server.
Thanks to Arif Che Hussin for introducing me with this cool opensource HCI deployment.
In this tutorial, I’m using an E-2286G bare metal server with VPC 2.0 enabled
Requirements:
- A single Cloud Server for hosting ISO files, vmzlinuz, initrd, and config-create.yaml files. I’m just using apache2 to run :80 ports. (hostname: http-vm)
- A bare-metal servers of E-2286G (hostname: harvester01). Please enable VPC 2.0 for private IP
First up, login to http-vm and install apache2 then start the apache2 service. Please disable all firewalls or allow :80 port
Then, download all these files based on the latest Harvester version
https://github.com/harvester/harvester/releases/
I downloaded these file to my /var/www/html
💿 https://releases.rancher.com/harvester/v1.3.1/harvester-v1.3.1-amd64.iso📁 https://releases.rancher.com/harvester/v1.3.1/harvester-v1.3.1-vmlinuz-amd64📁 https://releases.rancher.com/harvester/v1.3.1/harvester-v1.3.1-initrd-amd64
📁 https://releases.rancher.com/harvester/v1.3.1/harvester-v1.3.1-rootfs-amd64.squashfs
Next, I create a config-create.yaml files to define my installation configuration of Harvester
scheme_version: 1
token: your-token # Replace with a desired token
os:
hostname: node1 # Set a hostname.
ssh_authorized_keys:
- ssh-rsa # Add ssh key here
password: yourp@ssword # Replace with your password
dns_nameservers:
- 8.8.8.8
- 1.1.1.1
ntp_servers:
- 0.suse.pool.ntp.org
- 1.suse.pool.ntp.org

subnet_mask: 255.255.240.0 # Replace with your desired netmask

vip: 139.180.138.21 # The Public IP provided by Vultr to access the Harvester GUI.
vip_mode: static
vip_hw_addr: 3c:ec:ef:b9:c2:86 # Specify the MAC address for the VIP interface
vip_netmask: 255.255.254.0 # Netmask for VIP
vip_gateway: 139.180.138.1 # Gateway for the VIP
#Subnotes you can get all config of our server IP/MAC details in Vultr Settings

Then, navigate to Vultr Dashboard -> Products -> Orchestration -> Scripts -> Add Startup Scripts

Type: PXE

Boot up the server normally with the PXE config selected when you deploy the server

The installation process will be something like this

A successfully booted up servers

The server is now easily booted up and ready to use for Virtualization or K8S deployment.
Next, I will demonstrate how to join multiple nodes in Harvester and controlled by Rancher deployment.
Arigato and happy k8s!
