Attempts at cross-platform orchestration

Caution

HEAVILY WORK IN PROGRESS - DO NOT USE

Overview

Features

• Hashicorp Packer
• Hashicorp Terraform

Target platforms

• Proxmox (QEMU)
• vSphere

Guest OS

• openSUSE MicroOS

Packer

cd <project-dir>/packer

Setup

1. Create HCL config files. Replace VARIANT with an available platform name.

cp openSUSE_MicroOS-selfinstall.VARIANT.pkr.hcl.dist openSUSE_MicroOS-selfinstall.pkr.hcl
cp variables.pkrvars.proxmox.VARIANT.dist variables.pkrvars.hcl

2. Adjust the config values in variables.pkrvars.hcl accordingly.
3. Initialize Packer:

packer init openSUSE_MicroOS-selfinstall.pkr.hcl

4. Create an SSH key-pair to let Packer access the temporary system during the build process:

ssh-keygen -t ed25519 -C "Packer" -f ./ssh_files/packer

Build

packer build -var-file="variables.pkrvars.hcl" .

Terraform

cd <project-dir>/terraform

Setup

1. Create the Terraform module wrapper for your platform. Replace VARIANT with an available platform name. No adjustments need to be done in this file.

cp nodes.VARIANT_vm.tf.dist nodes.tf

2. Create a config file to hold all custom settings:

cp terraform.tfvars.dist terraform.tfvars

3. Uncomment all settings for the chosen platform and set their values in terraform.tfvars.
4. Initialize Terraform:

terraform init

Build

terraform apply

If there's an issue when creating too many VM's at the same time with Terraform and Proxmox, try to limit parallel activities:

terraform apply -parallelism=1
