unsplash-film

Let’s use Node.js to interact with cloud resources. Make sure node is installed on your local computer.

    $ node --version
    
    v12.13.0

Install Node.js-based Google Cloud Client Library. Enter the following command

    $ sudo yarn add @google-cloud/compute 
    
    //if you are a npm user
    $ sudo npm install @google-cloud/compute

Initiate Instance script.js

    const GCE = require('@google-cloud/compute')
    const my_instance =  new GCE({projectId: 'YOUR_PROJECT_ID'})
    
    const zone = gce.zone('asia-east1-b');
    
    console.log('Getting your VMs...');
    
    zone.getVMs().then((data) => {
        data[0].forEach((vm) => {
            console.log('Found a VM called', vm.name);
        });
        console.log('Done. ');
    });
    $ node script.js
    
    Getting your VMs...
    Found a VM called learning-cloud-demo
    Done.

Stop Instance script.js

    const GCE = require('@google-cloud/compute')
    const my_instance =  new GCE({projectId: 'sincere-loader-258805'})
    const zone = my_instance.zone('asia-east1-b');
    
    console.log('Getting your VMs...');
    
    zone.getVMs().then((data) => {
        data[0].forEach((vm) => {
            console.log('Found a VM called', vm.name);
            console.log('Stooping', vm.name, '...');
            vm.stop((err, operation) => {
                operation.on('complete', (err) => {
                    console.log('Stopped', vm.name);
                });
            })
        }); 
    });
    $ node script.js
    
    Getting your VMs...
    Found a VM called learning-cloud-demo
    Stooping learning-cloud-demo ...
    Stopped learning-cloud-demo

The command node script.js shows taht VM is now being stopped and can be restarted later if necessary.
