Hello Readers! In this blog we will see How To Create Aws VPC Using Boto3 Python. So before starting firstly we will see what is Boto3 and some short introduction about Aws VPC ?

What is Boto3 ?

Boto3 is the name of python sdk for AWS or you can say it is a module, library or API to work with AWS Services using python Scripts.
Using Boto3 we can create, delete and update AWS Services.
Boto3 can be executed from local server or using AWS lambda Service.
If we have to work with AWS Services using python we have to install Boto3.

What is Aws VPC ?

Amazon VPC is a Virtual Network that closely resembles a traditional networking that you operate in your own data center , with the benefits of using the scalable Infrastructure of AWS.
It is logically Isolated from other Virtual network in the AWS Cloud.

Prerequisites:

Create IAM User
Install AWS CLI and configure
python3
boto3

What we will do

Install Boto3
Know the required method
Create an VPC using Python Boto3

Python comes by default in Ubuntu 18.04 Server, so you do not need to install it.

To check the Python version on your system, use the following command.

which python
/usr/bin/python --version

or
python --version

If you do not have python than you can execute the following command to first update the local repo.

sudo apt update

To install pip use by this command.

sudo apt install python-pip

To check the version of Pip installed, you can execute the following command.

pip --version

Install boto3:

Install Boto3, by using this command:

pip3 install boto3

To check if the Boto3 is installed and to check its version, execute the following command.

pip show boto3

Let’s get started !

Know the required methods

To create an VPC and its dependent components we will use this methods.

create_vpc
create_route_table
create_internet_gateway
create_subnet
associate_with_subnet

Now, let’s see the methods with their list of acceptable parameters for creating an vpc.

Syntax of create_vpc method

response = client.create_vpc(
    CidrBlock='string',
    AmazonProvidedIpv6CidrBlock=True|False,
    Ipv6Pool='string',
    Ipv6CidrBlock='string',
    DryRun=True|False,
    InstanceTenancy='default'|'dedicated'|'host',
    Ipv6CidrBlockNetworkBorderGroup='string'
)

CidrBlock: The IPv4 network range for the VPC, in CIDR notation. This is an important field and an VPC can’t we create without this.

Syntax of create_route_table method

route_table = ec2.create_route_table(
    DryRun=True|False,
    VpcId='string'
)

VpcId: This ID of an VPC. This is also an important field and use to create a Route Table in the Specified VPC.

Syntax of create_internet_gateway method

response = client.create_internet_gateway(
    DryRun=True|False
)

Every VPC has a single Internet Gateway. This will be attache with the VPC

Syntax of create_subnet method

subnet = ec2.create_subnet(
    AvailabilityZone='string',
    AvailabilityZoneId='string',
    CidrBlock='string',
    Ipv6CidrBlock='string',
    OutpostArn='string',
    VpcId='string',
    DryRun=True|False
)

basically this is use to subdivide the VPC.

Syntax of associate_with_subnet method

route_table_association = route_table.associate_with_subnet(
    DryRun=True|False,
    SubnetId='string',
    GatewayId='string'
)

SubnetId: The ID of the subnet.

Create a VPC using Python Boto3

Step 1: I will create an VPC, create “boto.py” name of it and also you can give other name of your files.

firstly you have need to change the value of “aws_access_key_id_value” and “aws_secret_access_key_value” with your own access_key_id and access_key_value respectively. Also change the value of “region_name”.

If you want you can change the values of CidrBlock for “create_vpc” and “create_subnet” or you can keep as is and you can use an editor according your choice.

vim boto.py

import boto3

ec2 = boto3.resource('ec2', aws_access_key_id='ACCESS-KEY-OF-THE-AWS-ACCOUNT',
                     aws_secret_access_key='SECRETE-KEY-OF-THE-AWS-ACCOUNT',
                     region_name='AWS-Region')

vpc = ec2.create_vpc(CidrBlock='192.168.0.0/16')
# Assign a name to the VPC
vpc.create_tags(Tags=[{"Key": "Name", "Value": "my_vpc"}])
vpc.wait_until_available()
print(vpc.id)

# Create and Attach the Internet Gateway
ig = ec2.create_internet_gateway()
vpc.attach_internet_gateway(InternetGatewayId=ig.id)
print(ig.id)

# Create a route table and a public route to Internet Gateway
route_table = vpc.create_route_table()
route = route_table.create_route(
    DestinationCidrBlock='0.0.0.0/0',
    GatewayId=ig.id
)
print(route_table.id)

# Create a Subnet
subnet = ec2.create_subnet(CidrBlock='192.168.1.0/24', VpcId=vpc.id)
print(subnet.id)

# associate the route table with the subnet
route_table.associate_with_subnet(SubnetId=subnet.id)

Now, to create a VPC with the above specific configuration, execute the python script using this command.

python3 boto.py

You can verify if the VPC has been created from the AWS Console.

In the above screenshot, you can see that the VPC with the specific CIDR and Name has been created. You can check for components like Subnet, Internet Gateway, Route Table.
