This repo is an example on how to build a VPC using Terraform with:
(Just like the "Create VPC and more" button in the AWS Console)
- 1..n AZs
- public and private subnets in each AZ
- an internet gateway for the public subnets
- route tables and routes for the public and private subnets
- an S3 endpoint that the private routes route to
- an EC2 Ubuntu host on each public subnet with docker installed
- It will output the Public IPs of the hosts at the end of the build for you
- You will have to create a key pair to SSH into the nodes if you want and update the name of the key in the code. I'm sure you can find it.
- You will have to export an environment variable called TF_VAR_my_internet_ip= if you want the security group to work properly
- You can control the number of AZs and CIDR blocks by modifying the values in terraform.tfvars
Thanks to Derek Morgan and his YouTube video that taught me the Terraform basics.
Sample output of Terraform plan:
Basically, this terraform plan does the same thing as if you clicked on this in the AWS Console: (except you get Ubuntu hosts with this plan)
Additionally - similar functionality but pretty weak scripts included here in the same repo:
- buildaws.sh - shell script just calling the AWS CLI
- buildaws.py - python script just calling the AWS CLI
- build_aws_with_boto3.py - python script using boto3 to make the API calls directly
