Google Compute Engine lets you create and run virtual machines on Google infrastructure. Compute Engine offers scale, performance, and value that allows you to easily launch large compute clusters on Google's infrastructure. There are no upfront investments and you can run thousands of virtual CPUs on a system that has been designed to be fast, and to offer strong consistency of performance.
You can create virtual machines running different operating systems, including multiple flavors of Linux (Debian, Ubuntu, Suse, Red Hat, CoreOS) and Windows Server!
Follow along this lab to learn about how to create virtual machine instances of various machine types.
The instructor will be sharing with you temporary accounts with existing projects that are already setup so you do not need to worry about enabling billing or any cost associated with running this codelab. Note that all these accounts will be disabled soon after the codelab is over.
Once you have received a temporary username / password to login from the instructor, log into Google Cloud Console: https://console.cloud.google.com/.
Here's what you should see once logged in :
Note the project ID you were assigned ( "
codelab-test003" in the screenshot above). It will be referred to later in this codelab as
Certain Compute Engine resources live in regions or zones. A region is a specific geographical location where you can run your resources. Each region has one or more zones. For example, the
us-central1 region denotes a region in the Central United States that has zones
Virtual machine Instances and persistent disks live in a zone, and these are referred to as zonal resources. For example, to attach a persistent disk to a virtual machine instance, both resources must be in the same zone.
In this section, you'll learn how to create a new Google Compute Engine virtual machine instance from the Cloud Console.
Navigate to the the Google Cloud Console from another browser tab/window, to https://console.cloud.google.com. Use the login credential given to you by the lab proctor.
In the Google Developer Console, click the Menu icon on the top left of the screen:
Then navigate to Compute Engine > VM Instances
This may take a minute to initialize for the first time. Once initialized, you should see the following if the project has no virtual machine instances:
To create a new instance, click Create instance
There are many parameters you can configure when creating a new instance. Let's use the following:
Learn more about zones in Regions & Zones documentation.
Note: remember the zone that you selected, you'll need it later.
This is a 1-CPU, 3.75GB RAM instance.
There are a number of machine types, ranging from micro instance types to 32-core/208GB RAM instance types. Learn more about this and custom machine types in the Machine Types documentation.
Note: A new project has a default resource quota, which may limit the number of CPU cores. You can request more for your projects.
There are a number of images to choose from, including: Debian, Ubuntu, CoreOS as well as premium images such as Red Hat Enterprise Linux and Windows Server. See Operating System documentation for more detail.
Note: You may optionally choose
Check this option so that we can access a webserver that we will install later.
Note: This will automatically create firewall rule to allow HTTP traffic on port 80.
Click on Create to create the new virtual machine instance!
Once finished, you should see the new virtual machine in the VM Instances page. Note down the
External IP of the machine on the VM instances page - you will need this later
To SSH into the virtual machine, click on SSH on the right hand side.
Once ssh'ed, get
root access using
$ sudo su -
root user, install NGINX:
$ apt-get update Get:1 http://security.debian.org jessie/updates InRelease [63.1 kB] Ign http://httpredir.debian.org jessie InRelease Get:2 http://security.debian.org jessie/updates/main amd64 Packages [247 kB] ... $ apt-get install nginx -y Reading package lists...

Check that NGINX is running:
$ ps auwx | grep nginx root 1373 0.0 0.0 91180 2960 ? Ss 03:59 0:00 nginx: master process /usr/sbin/nginx -g daemon on ; master_process on; www-data 1374 0.0 0.0 91544 3652 ?

Awesome! Let's see the web page! Use the
External IP of the virtual machine instance that you noted down before, and in a new browser window/tab, browse to
http://EXTERNAL_IP/, you should see the default page.
Rather than using the Google Cloud Console to create a virtual machine instance, you can also use the command line tool called
We'll use Google Cloud Shell, a command line environment running in the Cloud. This Debian-based virtual machine is loaded with all the development tools you'll need (
git and others) and offers a persistent 5GB home directory.
Open the Google Cloud Shell by clicking on the icon on the top right of the screen:
Once opened, you can create a new virtual machine instance from the command line by using
gcloud (feel free to use another zone closer to you) :
$ gcloud compute instances create gcelab2 --zone us-central1-c Created [...gcelab2]. NAME ZONE MACHINE_TYPE PREEMPTIBLE INTERNAL_IP EXTERNAL_IP STATUS gcelab2 us-central1-c n1-standard-1 10.240.X.X X.X.X.X RUNNING
The instance was created with some default values:
n1-standard-1machine type. You can select another machine type such as
n1-highcpu-6. If none of the predefined machine types match your needs, use a custom machine type.
gcloud compute instances create --help to see all the defaults.
Finally, you can SSH into your instance using
gcloud as well (make sure you adjust your zone if you've used something else when creating the instance, or omit the
--zone flag if you've set the option globally):
$ gcloud compute ssh gcelab2 --zone us-central1-c Warning: Permanently added 'compute.745019997240233037' (ECDSA) to the list of known hosts. ... username@gcelab2:~$
Disconnect from SSH by existing from the remote shell:
In the previous section, you learned that there are a number of predefined machine types that you can choose for your virtual machine. However, if predefined machine types do not meet your needs, you can create an instance with custom virtualized hardware settings. Specifically, you can create an instance with a custom number of vCPUs and amount of memory, effectively using a custom machine type.
Create another virtual machine instance using the Google Cloud Console, and choose a custom machine type by clicking Customize:
Then, you use the sliders to pick the exact number of cores and memory to use:
Create a virtual machine instance with 2 vCPU and 5 GB of RAM.
It's time to shut down those VM instances to save on cost and to be an overall good cloud citizen. You can either decide to delete the instances or simply stop them :
If you decide to delete the VM instances (after all they're really easy to recreate), then remember that this will also delete the VM boot disks. If you'd like persistent disks, check out the Disks and Snapshots sections of the compute engine console :
Google Compute Engine is the foundation to Google Cloud Platform's Infrastructure-as-a-Service. You can easily map your existing server infrastructure, load balancers, and network topology to Google Cloud Platform.
