How to Create VPC (Virtual Private Cloud) Network in GCP

VPC is a virtual private cloud in public cloud like GCP (Google Cloud Platform) and AWS. In simple terms, VPC is a dedicated private network for your project in google cloud platform. It provides networking for virtual machines, containers and app engine.

In this guide, we will learn how to create customize VPC network in GCP (Google Cloud Platform) step by step. Without any further delay, let’s jump into steps.

1) Login to Google Cloud Console and Go to VPC networks

Login to your google cloud console and search vpc,

Search-VPC-GCP-Console

Click on ‘VPC network‘, it will open VPC networks page.

Note: In my case, I am using LinuxTechi project and have deleted the default VPC.

Let’s create new VPC in the next step.

2) Create VPC Network

Click on ‘Create VPC network‘ and we will get the following page, specify the following details.

  • VPC Name:  vpc-a
  • Description (Optional): Virtual Private Cloud in LinuxTechi Project
  • Subnet Create Mode: custom (If you choose automatic, it will create subnet in all regions automatically)

VPC-Name-Subnet-Creation-Mode-GCP

  • Subnet Name: linuxtechi-prv-subnet
  • Subnet Region: Europe-west2
  • IP address range: 10.30.0.0/26  (Specify the CIDR range as per requirement)
  • Private Google Access: Off (If you keep this option as ‘ON’ then it will allow this subnet to make API calls to GCP services privately)

  • Flow Logs:  off

Flow-Logs-VPC-GCP

  • Firewall Rules: Allow Ingress ICMP, RDP and SSH protocols/ ports. ( You can define your own custom rules)
  • Dynamic Routing Mode: Regional

In the last step, choose the MTU and then click on ‘Create’ to create VPC along with its subnet.

3) Verify VPC Network and Subnet

After the creation of VPC network, we will get following on VPC networks page, verify the VPC and subnet.

Verify-VPC-Network-Subnet-GCP

4) Test VPC Network and its Subnet

To test above created VPC netwrok, let’s create one virtual machine inside the VPC. From the search bar, search ‘add vm instance’.

Click-Add-VM-Instance-GCP

Specify the VM details like VM Name, Region (Choose the region where we have created subnet for vpc-a).

VM-Creation-GCP-Console

In the networking section, choose the VPC as ‘vpc-a’ and subnet as ‘linuxtechi-prv-subnet

VPC-Selection-During-VM-Creation-GCP

Now, click on ‘Create’ option to launch the virtual machine.

Create-Option-VM-Creation-GCP

Once the VM comes up, try to take its ssh console and verify the internal IP whether it is coming from subnet of VPC-A.

VM-Console-GCP

Perfect, above confirms that VM has been created successfully and got the IP from subnet of VPC-A.

Note: Kindly delete the virtual machine after the testing to avoid unnecessary billing.
