AWS CLI with VPC

Create VPC

To create a Virtual Private Cloud (VPC) using AWS CLI, follow these steps:

This section covers basic VPC creation using AWS CLI.

  1. Open your terminal and configure AWS CLI with your credentials:

    aws configure

  2. Create a VPC with a CIDR block:

    aws ec2 create-vpc --cidr-block 10.0.0.0/16
Ensure you use a unique CIDR block that doesn’t overlap with other networks.

Create VPC Components

After creating the VPC, you can add components like subnets, route tables, and internet gateways.

  1. Create a Subnet:

    aws ec2 create-subnet --vpc-id <vpc-id> --cidr-block 10.0.1.0/24

  2. Create an Internet Gateway:

    aws ec2 create-internet-gateway

    Attach the internet gateway to your VPC:

    aws ec2 attach-internet-gateway --vpc-id <vpc-id> --internet-gateway-id <igw-id>
Ensure you modify the route table to allow internet traffic for public subnets.
