Lxc-query NPM | npm.io

LXC Query

A Node.js LXD client which uses your local instance of LXD and lxc query to manage your local or remote LXD servers.

You must be using >= LXD 2.17

Install

Require this package with npm using the following command:

$ npm i lxc-query

Usage

Essentially you can do any LXD operation with the single lxc.query method, or you can use the helper methods which cover all the LXD endpoints.

Parameters & Call

Parameter	Type	Description	Default
remote	string	LXD remote and endpoint	local
rest method	string	e.g GET, POST, DELETE, PUT, PATCH	GET
payload	object \| json string	Rest json payload
mutator	function	Pre-resolve mutation function

const lxc = require('lxc-query')

lxc.query('remote:/1.0', 'GET', {}).then(response => {
    console.log(response)
})

Express example

Using express you can map the rest calls to the lib as shown below:

const lxc = require('lxc-query')
const express = require('express')
const app = express()

app.all('/*', (req, res) => {
    lxc.query(req.url.substr(1), req.method, req.body).then(response => res.json(response))
})

app.listen(3000)

So using the above if you visited http://127.0.0.1:3000/local:/1.0/containers it would proxy it though to local LXD server, list containers.. You could do this for any rest method or LXD endpoint, with the addition that local: can be any of your defined remotes!
