This is my own Terraform configuration repository for my homelab, based on libvirt and cloud-init system images.
The main configuration file is terraform.tfvars, new VMs can be created by adding new entries in the hash vms_list. Each VM description will be converted to cloud-init configuration and be used to bootstrap the system on boot.
- Verify the terraform HCL code in the current repository:
tflint - Reformat the configuration using the official styling guidelines:
terraform fmt - Validate the configuration:
terraform validate
- Prepare the working directory:
terraform init - Show changes to the infrastructure required by the current configuration:
terraform plan - Create or modify the infrastructure:
terraform apply - Destroy all the infrastructure:
terraform destroy
- List all resources:
terraform state list - Destroy a particular VM:
terraform destroy -target 'module.vms["tf-openbsd"]'
On a booted VM, you can verify the generated cloud-init configuration with this command as root: cloud-init schema --system
