### Launch instances
This function will create and start a new instance based on the object provided as argument.

```js
const { launchImage } = require("multipass-control")

const main = async () => {
    const launchInstance = await launchImage({ 
        image: "core18", 
        name: "flattering-racoons" 
    });
    return launchInstance;
}

The function takes image as a necessary object property, however you can customize your instance by providing other properties as well. These are all the properties the object takes:

Instance information

This function returns a JSON object with properties of the instances provided as arguments

const { imageInfo } = require("multipass-control")

const main = async () => {
    const instanceInformation = await imageInfo("flattering-racoons");
    return instanceInformation;
}

Start instances

This function will start the instance provided as the argument.

const { startImage } = require("multipass-control")

const main = async () => {
    const startInstance = await startImage("flattering-racoons");
    return startInstance;
}

    {
      "successful": true,
      "error": null
    }

Stop instances

This function will stop the instance provided as the argument.

const { stopImage } = require("multipass-control")

const main = async () => {
    const stopInstance = await stopImage("flattering-racoons");
    return stopInstance;
}

Restart instances

This function will restart the instance provided as the argument.

const { restartImage } = require("multipass-control")

const main = async () => {
    const restartInstance = await restartImage("flattering-racoons");
    return restartInstance;
}

{
  "successful": true,
  "error": null
}

Suspend instances

This function will suspend the instance provided as the argument.

const { suspendImage } = require("multipass-control")

const main = async () => {
    const suspendInstance = await suspendImage("flattering-racoons");
    return suspendInstance;
}

    {
      "successful": true,
      "error": null
    }

Delete instances

This function will delete the instance provided as the argument.

const { deleteImage } = require("multipass-control")

const main = async () => {
    const deleteInstance = await deleteImage("flattering-racoons");
    return deleteInstance;
}

Recover instances

This function will recover the deleted instance provided as the argument.

const { recoverImage } = require("multipass-control")

const main = async () => {
    const recoverInstance = await recoverImage("flattering-racoons");
    return recoverInstance;
}

    {
      "successful": true,
      "error": null
    }

Execute command on instances

This function will execute the command on the instance provided as the argument.

const { executeCommand } = require("multipass-control")

const main = async () => {
      const executing = await executeCommand({
        name: "flattering-racoons",
        cmd: "pwd",
      });
    return availableImages;
}

The function takes name and cmd as a necessary object property, however you can customize your instance by providing other properties as well. These are all the properties the object takes:

Keep in mind that all commands are run with respect to /home/ubuntu directory.

Purge deleted instances

This function will remove all deleted instances from your system permanently

const { purgeImages } = require("multipass-control")

const main = async () => {
    const purgeInstances = await purgeImages();
    return purgeInstances;
}

{
  "successful": true,
  "error": null
}
