# VM Service Template
This repository is a starter template for deploying one or more service VMs in Proxmox using Terraform, then configuring and launching applications with Ansible and Docker Compose.
It is designed to work with a shared Terraform module stored in a separate repository. This repo acts as the wrapper/root module and provides the service-specific inputs, deployment workflow, and app stack files.
## What this repo does
- Creates one or more Proxmox VMs from a reusable Terraform module.
- Uses cloud-init and QEMU guest agent in the template VM.
- Writes the VM IP address into Ansible inventory.
- Tags VMs with Terraform, Docker, service name, and IP metadata.
- Deploys an application stack with Ansible and Docker Compose.
## Repository layout
```text
terraform/ Terraform wrapper for the shared Proxmox module.
compose/ Docker Compose application files.
ansible/ Playbook and role used to configure and deploy the app.
.gitea/ Workflow files for apply and deploy.
```
## Requirements
- Terraform installed locally or in CI.
- Access to the Proxmox API.
- A shared Proxmox VM module in a separate repository.
- Ansible installed for application deployment.
- Docker and Docker Compose available on the target VM.
## How it works
1. Terraform reads the instance configuration from `terraform.tfvars`.
2. Terraform calls the shared Proxmox module to create the VM.
3. Terraform outputs the VM IP address and tags.
4. The workflow writes the IP into `ansible/inventory/hosts.ini`.
5. Ansible connects to the VM and deploys the Compose stack.
## Single instance
Use `instance_mode = "single"` and define one `instance` object.
Example:
```hcl
instance_mode = "single"
instance = {
service_name = "grafana"
vm_name = "grafana-01"
node_name = "pop"
app_port = 3000
app_image = "grafana/grafana:latest"
vm_tags = ["monitoring"]
}
```
## Multi instance
Use `instance_mode = "multi"` and define an `instances` map.
Example:
```hcl
instance_mode = "multi"
instances = {
grafana = {
service_name = "grafana"
vm_name = "grafana-01"
node_name = "pop"
app_port = 3000
app_image = "grafana/grafana:latest"
vm_tags = ["monitoring"]
}
caddy = {
service_name = "caddy"
vm_name = "caddy-01"
node_name = "pop"
app_port = 80
app_image = "caddy:latest"
vm_tags = ["proxy"]
}
}
```
## Defaults
The template supports module defaults for items like:
- datastore
- BIOS
- machine type
- SSH key
- bridge
- CPU, RAM, and disk size
Override only what you need in the service repo.
## Running locally
```bash
cd terraform
cp single.tfvars.example terraform.tfvars
terraform init
terraform apply
```
After Terraform finishes, run:
```bash
cd ..
ansible-playbook -i ansible/inventory/hosts.ini ansible/playbooks/deploy.yml
```
## Workflow trigger
This template is intended to be run after the repository is created from it.
The usual flow is:
- create a new repo from this template,
- update the tfvars file,
- trigger the workflow manually with `workflow_dispatch`,
- or push the first commit to start deployment.
## Notes
- The shared Proxmox module should live in a separate repository.
- The service repo should contain the wrapper, not the internal Proxmox resource logic.
- VM IP tags are generated after Terraform apply.
- If the VM disk is resized manually in Proxmox, Terraform may see drift on the next run.
## Example use case
This template works well for service VMs such as:
- Grafana
- Caddy
- Jellyfin
- Code Server
- Monitoring or proxy VMs
