# ProxmoxAAS API - REST API for ProxmoxAAS Dashboard
ProxmoxAAS API provides functionality for the Dashboard by providing a proxy API for the Proxmox API, and an API for requesting resources within a defined quota.

## Installation

### Prerequisites
- [ProxmoxAAS-Dashboard](https://git.tronnet.net/tronnet/ProxmoxAAS-Dashboard)
- Proxmox VE Cluster (v7.0+)
- Reverse proxy server which can proxy the dashboard and API
	- FQDN
- Server with NodeJS (v18.0+) and NPM installed

### Configuring API Token and Permissions
In Proxmox VE, follow the following steps:
1. Add a new user `proxmoxaas-api` to Proxmox VE
2. Create a new API token for the user `proxmoxaas-api` and copy the secret key to a safe location
3. Create a new role `proxmoxaas-api` with at least the following permissions: 
    - VM.* except VM.Audit, VM.Backup, VM.Clone, VM.Console, VM.Monitor, VM.PowerMgmt, VM.Snapshot, VM.Snapshot.Rollback
    - Datastore.Allocate, Datastore.AllocateSpace, Datastore.Audit
    - User.Modify
	- Pool.Audit
4. Add a new API Token Permission with path: `/`, select the API token created previously, and role: `proxmoxaas-api`
5. Add a new User Permission with  path: `/`, select the `proxmoxaas-api` user, and role: `proxmoxaas-api`

### Installation - API
1. Clone this repo onto `Dashboard Host`
2. Run `npm install` to initiaze the package requirements
3. Copy `template.config.json` as `config.json` and modify the following values:
	1. In `backends/pve/config`:
		- url: the URI to the Proxmox API, ie `http://<proxmoxhost>:8006/api2/json` or `http://<proxmox URL>/api2/json` if Proxmox VE is behind a reverse proxy. 
		- token: the user(name), authentication realm (pam), token id, and token secrey key (uuid)
		- root (**Optional**): In order to allow users to customize instance pcie devices, the API must use the root credentials for privilege elevation. Provide the root username, ie. `root@pam`, and root user password
	2. In `backends/paasldap/config` (**Optional**):
		- url: url to a PAAS-LDAP server API ie. `http://<paasldap-host>:8082`
	3. In `handlers/auth`:
		- Add any authentication handlers to be used by the API. Add the realm name (ie. `pve`) as the key and the handler name as provided in `backends`. For example, a PAAS-LDAP handler could be added as `"paas-ldap": "paasldap"` and users in the realm `user@paas-ldap` will use this handler to perform auth actions. Refer to [backends](#Backends)
	4. In `application`:
		- hostname - the ProxmoxAAS-Dashboard URL, ie `host.domain.tld`
		- domain - the base domain for the dashboard and proxmox, ie `domain.tld`
    	- listenPort - the port you want the API to listen on, ie `8081`
	5. In `useriso`:
		- node: host of storage with user accessible iso files
		- storage: name of storage with user accessible iso files
4. Start the service using `node .`, or call the provided shell script, or use the provided systemctl service script

### Installation - Reverse Proxy
1. Configure nginx or preferred reverse proxy to reverse proxy the dashboard. The configuration should include at least the following:
```
server {
	listen 443 ssl;
	server_name paas.<FQDN>;
	location / {
		return 301 "/dashboard/";
	}
	location /dashboard/ {
		proxy_pass http://proxmoxaas.dmz:8080/;
		proxy_redirect default;
	}
	location /api/ {
		proxy_pass http://proxmoxaas.dmz:80/api/;
		proxy_redirect default;
	}
}
```
2. Start nginx with the new configurations

### Result
After these steps, the ProxmoxAAS Dashboard should be available and fully functional at `paas.<FQDN>` or `paas.<FQDN>/dashboard/`.
