The right way to create a Website-to-Website VPN in Boto3 Python


To create a site-to-site VPN utilizing the Boto3 library in Python, you possibly can make the most of the boto3.shopper('ec2') shopper to work together with the AWS EC2 service. Right here’s an instance code snippet to create a site-to-site VPN:

import boto3

ec2_client = boto3.shopper('ec2')

# Create VPN Gateway
vpn_gateway_response = ec2_client.create_vpn_gateway(Sort='ipsec.1', TagSpecifications=[{
    'ResourceType': 'vpn-gateway',
    'Tags': [{'Key': 'Name', 'Value': 'SiteToSiteVPN'}]
}])
vpn_gateway_id = vpn_gateway_response['VpnGateway']['VpnGatewayId']

# Create VPN Connection
vpn_connection_response = ec2_client.create_vpn_connection(
    Sort='ipsec.1',
    CustomerGatewayId='<CUSTOMER_GATEWAY_ID>',
    VpnGatewayId=vpn_gateway_id,
    Choices={
        'StaticRoutesOnly': True
    },
    TagSpecifications=[{
        'ResourceType': 'vpn-connection',
        'Tags': [{'Key': 'Name', 'Value': 'SiteToSiteVPNConnection'}]
    }]
)
vpn_connection_id = vpn_connection_response['VpnConnection']['VpnConnectionId']

# Create VPN Connection Route
ec2_client.create_vpn_connection_route(
    DestinationCidrBlock='<DESTINATION_CIDR_BLOCK>',
    VpnConnectionId=vpn_connection_id
)

Within the above code, it is advisable to change <CUSTOMER_GATEWAY_ID> with the ID of the shopper gateway representing the distant web site, and <DESTINATION_CIDR_BLOCK> with the CIDR block of the distant community you wish to hook up with.

The code snippet creates a VPN gateway utilizing the create_vpn_gateway methodology, passing the specified parameters comparable to the kind of VPN (Sort) and tags (TagSpecifications). It then retrieves the VPN gateway ID from the response.

Subsequent, the code creates a VPN connection utilizing the create_vpn_connection methodology, offering the shopper gateway ID, VPN gateway ID, choices (on this case, StaticRoutesOnly), and tags.

Lastly, the code creates a VPN connection route utilizing the create_vpn_connection_route methodology, specifying the vacation spot CIDR block and the VPN connection ID.

You’ll be able to run this code utilizing Python and the Boto3 library to create the site-to-site VPN sources in AWS EC2.
