# Proxmox App Projects (LXC-first)

This guide documents the **modular app-project stack** that provisions Proxmox guests (dev/qa/prod) and configures a full-stack app layout on them.

## What you get

- Proxmox provisioning via API (currently **LXC**; VM support remains via existing `roles/proxmox_vm` KVM path)
- A deployment user (`appuser`) with your SSH key
- `/srv/app/backend` and `/srv/app/frontend`
- Env file `/srv/app/.env.<dev|qa|prod>`
- `/usr/local/bin/deploy_app.sh` to pull the right branch and restart services
- systemd services:
  - `app-backend.service`
  - `app-frontend.service`

## Where to configure projects

Edit:

- `inventories/production/group_vars/all/main.yml`

Under `app_projects`, define projects like:

- `projectA.repo_url`
- `projectA.envs.dev|qa|prod.ip/gateway/branch`
- `projectA.guest_defaults` (cores/memory/rootfs sizing)
- `projectA.deploy.*` (install/build/migrate/start commands)

Adding **projectB** is just adding another top-level `app_projects.projectB` entry.

## Proxmox credentials (vault)

This repo already expects Proxmox connection vars in vault (see existing Proxmox playbooks). Ensure these exist in:

- `inventories/production/group_vars/all/vault.yml` (encrypted)

Common patterns:

- `vault_proxmox_host`: `10.0.10.201`
- `vault_proxmox_user`: e.g. `root@pam` or `ansible@pve`
- `vault_proxmox_node`: e.g. `pve`
- Either:
  - `vault_proxmox_password`, or
  - `vault_proxmox_token` + `vault_proxmox_token_id`

## Debian LXC template

The LXC provisioning uses `lxc_ostemplate`, defaulting to a Debian 12 template string like:

`local:vztmpl/debian-12-standard_12.7-1_amd64.tar.zst`

If your Proxmox has a different template filename, change `lxc_ostemplate` in `inventories/production/group_vars/all/main.yml`.

## Running it

Provision + configure one project:

```bash
ansible-playbook -i inventories/production playbooks/app/site.yml -e app_project=projectA
```

Provision + configure all projects in `app_projects`:

```bash
ansible-playbook -i inventories/production playbooks/app/site.yml
```

Only provisioning (Proxmox API):

```bash
ansible-playbook -i inventories/production playbooks/app/provision_vms.yml -e app_project=projectA
```

Only OS/app configuration:

```bash
ansible-playbook -i inventories/production playbooks/app/configure_app.yml -e app_project=projectA
```

## Optional: SSH aliases on your workstation

To write `~/.ssh/config` entries (disabled by default):

```bash
ansible-playbook -i inventories/production playbooks/app/ssh_client_config.yml -e manage_ssh_config=true -e app_project=projectA
```

This creates aliases like `projectA-dev`, `projectA-qa`, `projectA-prod`.
