Creating the Internet Gateway

The Internet gateway is the prerequisite for the NAT gateway, which will be created later.

To create the internet gateway and attach it to the VPC:

1. Run the following command:
   aws ec2 create-internet-gateway

Example output:

{
   "InternetGateway":{
      "Tags":[
         
      ],
      "InternetGatewayId":"igw-0ddcfa7511fe10b43",
      "Attachments":[
         
      ]
   }
}

2. Record the value of InternetGatewayId in your AWS worksheet.
3. Optionally, you might tag the internet gateway by running the following command:
   aws ec2 create-tags --resources <InternetGatewayId> --tags Key=Name,Value=<internet gateway name>
4. Attach the internet gateway to your previously-created VPC by running the following command (command has no output):
   aws ec2 attach-internet-gateway --internet-gateway-id <InternetGatewayId> --vpc-id <VPC Id>

For example:
aws ec2 attach-internet-gateway \
--internet-gateway-id igw-0ddcfa7511fe10b43 \
--vpc-id vpc-0143197ca9bd9c117
