Introduction

After the deployment of a VM, now it's time to expose it to the world

Example code

import { FilterOptions, GatewayNameModel } from "../src";
import { getClient } from "./client_loader";
import { log } from "./utils";

// read more about the gateway types in this doc: https://github.com/threefoldtech/zos/tree/main/docs/gateway
async function main() {
    const grid3 = await getClient();

    const gatewayQueryOptions: FilterOptions = {
        gateway: true,
        farmId: 1,
    };

    const gw = new GatewayNameModel();
    gw.name = "test";
    gw.node_id = +(await grid3.capacity.filterNodes(gatewayQueryOptions))[0].nodeId;
    gw.tls_passthrough = false;
    // the backends have to be in this format `http://ip:port` or `https://ip:port`, and the `ip` pingable from the node so using the ygg ip or public ip if available.
    gw.backends = ["http://185.206.122.35:8000"];

    // deploy
    const res = await grid3.gateway.deploy_name(gw);
    log(res);

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

    // // delete
    // const d = await grid3.gateway.delete_name({ name: gw.name });
    // log(d);

    grid3.disconnect();
}

main();

Detailed explanation

const gw = new GatewayNameModel();
gw.name = "test";
gw.node_id = +(await grid3.capacity.filterNodes(gatewayQueryOptions))[0].nodeId;
gw.tls_passthrough = false;
gw.backends = ["http://185.206.122.35:8000"];

• we created a gateway name model and gave it a name -that's why it's called GatewayName- test to be deployed on gateway node to end up with a domain test.gent01.devnet.grid.tf,
• we create a proxy for the gateway to send the traffic coming to test.ghent01.devnet.grid.tf to the backend http://185.206.122.35, we say tls_passthrough is false to let the gateway terminate the traffic, if you replace it with true your backend service needs to be able to do the TLS termination

deploying

// deploy
const res = await grid3.gateway.deploy_name(gw);
log(res);

this deploys GatewayName on the grid

getting deployment object

const l = await grid3.gateway.getObj(gw.name);
log(l);

getting the deployment information can be done using getObj

deletion

const d = await grid3.gateway.delete_name({ name: gw.name });
log(d);

Deploying a VM and exposing it over a Gateway using a Full domain

After the deployment of a VM, now it's time to expose it to the world

Example code

import { FilterOptions, GatewayFQDNModel } from "../src";
import { getClient } from "./client_loader";
import { log } from "./utils";

// read more about the gateway types in this doc: https://github.com/threefoldtech/zos/tree/main/docs/gateway
async function main() {
    const grid3 = await getClient();

    const gatewayQueryOptions: FilterOptions = {
        gateway: true,
        farmId: 1,
    };
    const gw = new GatewayFQDNModel();
    gw.name = "applyFQDN";
    gw.node_id = +(await grid3.capacity.filterNodes(gatewayQueryOptions))[0].nodeId;
    gw.fqdn = "test.hamada.grid.tf";
    gw.tls_passthrough = false;
    // the backends have to be in this format `http://ip:port` or `https://ip:port`, and the `ip` pingable from the node so using the ygg ip or public ip if available.
    gw.backends = ["http://185.206.122.35:8000"];

    // deploy
    const res = await grid3.gateway.deploy_fqdn(gw);
    log(res);

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

    // // delete
    // const d = await grid3.gateway.delete_fqdn({ name: gw.name });
    // log(d);

    grid3.disconnect();
}

main();

Detailed explanation

const gw = new GatewayFQDNModel();
gw.name = "applyFQDN";
gw.node_id = 1;
gw.fqdn = "test.hamada.grid.tf";
gw.tls_passthrough = false;
gw.backends = ["my yggdrasil IP"];

• we created a GatewayFQDNModel and gave it a name applyFQDNN to be deployed on gateway node 1 and specified the fully qualified domain fqdn to a domain we own test.hamada.grid.tf
• we created a record on our name provider for test.hamada.grid.tf to point to the IP of gateway node 1
• we specified the backened would be an yggdrassil ip so once this is deployed when we go to test.hamada.grid.tf we go to the gateway server and from their our traffic goes to the backend.

deploying

// deploy
const res = await grid3.gateway.deploy_fqdn(gw);
log(res);

this deploys GatewayName on the grid

get deployment object

const l = await grid3.gateway.getObj(gw.name);
log(l);

getting the deployment information can be done using getObj

deletion

const d = await grid3.gateway.delete_fqdn({ name: gw.name });
log(d);
