About

This project helps to create a fleet of Linux VPS bound with specific SSH key in ArvanCloud Service provider using Terraform. 4 modules have been developed in this project for different Linux distributions specified below:

CentOS
- 7
Debian
- 10 (Buster)
- 11 (Bullseye)
- 12 (Bookworm)
Rocky
- 8.5
- 9
Ubuntu
- 18.04 (Bionic)
- 20.04 (Focal)
- 22.04 (Jammy)

you can have a combination of linux machines from different distribiutions at the same time. even you can make customized OS template in your Arvanclpud panel and add it as module to the code and call it in main.tf file.

Example

before running code you are required to get API key from your Arvancloud panel and set it in terraform.tfvars:

ApiKey = "someapikey0123456789"

based on Arvancloud access regions at the time of writing this document, you can assign variable region with one of options below:

Region alias	Description
ir-thr-c1	Simin Datacenter located in Iran, Tehran
ir-thr-c2	Forough Datacenter located in Iran, Tehran
ir-tbz-dc1	Shahriar Datacenter located in Iran, Tabriz
ir-thr-w1	Forough Datacenter located in Iran, Tehran

for example, if you intend to provision a infrastructure in Tabriz datacenter set this in teraform.tafvars:

region = "ir-tbz-dc1"

if you are not familiar with SSH keypairs, read this instruction to generate an SSH keypair. in order to access your machines via SSH you need to set variable public-key in terraform.tfvars with the content of your generated public key file usually found in ~/.ssh/id_rsa.pub. please consider keeping your private key securely.

public_key = "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCmUs3m50UiEyBuswzg8gAUtI0ewRTHiqT6k1bsLCX3YWDrC7k+uLvBnxHoyKdCMedAg95Wf+rIc4Ph86m+LNyKrYN1Pji4/toWhNH1dQN5edadCnZXe9TrFwNIRfCSVsp1PDedAdvLut5V0mGLOA9l/iILjaCM+hw9ljV9XFnB5Na80R2T1C7oFXn2/bxp1+QCC5eUnVh3WkG9C9HNSh27eLP/mAW7OIhyt6PV5yOd8AtjIFoCAO0cCyMiH4btB488jWGezx47jRnfYBIHjkL9CnvkccAx3YSAiTcikIUJUDk3O+ptrkKckJ75Ea2yzMzvcAYhVEGrkw5gNzpX8x5R"

variable server_count is equivalent to the number of instances you wish to deploy, which is 0 by default. consider setting this parameter in terraform.tfvars before apply. for example if you want to create 3 instance from Ubunut and 2 instances of Rocky Linux:

server_count_rocky  = 2
server-count-ubuntu = 3

each module has a variable named image-name which could be set in module call in main.tf file. their default value is set to the latest version of each distribiution at the time of writing this document.

module "server-ubuntu" {
  source       = "./modules/server-ubuntu"
  region       = var.region
  ApiKey       = var.ApiKey
  key_name     = arvan_iaas_sshkey.ssh-key-user-terraform.name
  server-count = var.server-count-ubuntu
  image-name   = "Ubunut/18.04"
}
