Introduction

It is possible to deploy multiple VMs with the Javascript client.

Example code

import { DiskModel, FilterOptions, MachineModel, MachinesModel, NetworkModel } from "../src";
import { config, getClient } from "./client_loader";
import { log } from "./utils";

async function main() {
    const grid3 = await getClient();

    // create network Object
    const n = new NetworkModel();
    n.name = "monNetwork";
    n.ip_range = "10.238.0.0/16";

    // create disk Object
    const disk1 = new DiskModel();
    disk1.name = "newDisk1";
    disk1.size = 1;
    disk1.mountpoint = "/newDisk1";

    const vmQueryOptions: FilterOptions = {
        cru: 1,
        mru: 1, // GB
        sru: 1,
        availableFor: grid3.twinId,
        farmId: 1,
    };

    // create vm node Object
    const vm1 = new MachineModel();
    vm1.name = "testvm1";
    vm1.node_id = +(await grid3.capacity.filterNodes(vmQueryOptions))[0].nodeId;
    vm1.disks = [disk1];
    vm1.public_ip = false;
    vm1.planetary = true;
    vm1.cpu = 1;
    vm1.memory = 1024;
    vm1.rootfs_size = 0;
    vm1.flist = "https://hub.grid.tf/tf-official-apps/base:latest.flist";
    vm1.entrypoint = "/sbin/zinit init";
    vm1.env = {
        SSH_KEY: config.ssh_key,
    };

    // create disk Object
    const disk2 = new DiskModel();
    disk2.name = "newDisk2";
    disk2.size = 1;
    disk2.mountpoint = "/newDisk2";

    // create another vm node Object
    const vm2 = new MachineModel();
    vm2.name = "testvm2";
    vm2.node_id = +(await grid3.capacity.filterNodes(vmQueryOptions))[1].nodeId;
    vm2.disks = [disk2];
    vm2.public_ip = false;
    vm2.planetary = true;
    vm2.cpu = 1;
    vm2.memory = 1024;
    vm2.rootfs_size = 0;
    vm2.flist = "https://hub.grid.tf/tf-official-apps/base:latest.flist";
    vm2.entrypoint = "/sbin/zinit init";
    vm2.env = {
        SSH_KEY: config.ssh_key,
    };

    // create VMs Object
    const vms = new MachinesModel();
    vms.name = "monVMS";
    vms.network = n;
    vms.machines = [vm1, vm2];
    vms.metadata = "{'testVMs': true}";
    vms.description = "test deploying VMs via ts grid3 client";

    // deploy vms
    const res = await grid3.machines.deploy(vms);
    log(res);

    // get the deployment
    const l = await grid3.machines.getObj(vms.name);
    log(l);

    // // delete
    // const d = await grid3.machines.delete({ name: vms.name });
    // log(d);

    await grid3.disconnect();
}

main();

It's similiar to the previous section of deploying a single VM, but just adds more vm objects to vms collection.
