aws-vpc-hello-world-setup

This repository contains commands for creating basic network structure which contains private, public subnet within single VPC. Before executing commands in execute section, IAM user with Administrator authority(ex. admin.kim) has to be prepared after following instructions explained in this page. Then, corresponding access key and password has to be configured into local configuration file using aws configure command.

Environment

Execution environment setup

python3 --version  # Python 3.10.10
python3 -m venv venv
source venv/bin/activate
pip3 install typer==0.9.0 boto3==1.26.140

Execute

If administrator user profile is configured, use name of the profile as parameter of --profile-name argument. For example, every command below uses configured credential that corresponds to admin.kim.

1. create VPC

1. create a VPC
2. create configured security group and attach it to created VPC
3. create internet gateway and attach it to created VPC

python main.py configure-vpc \
    --profile-name=admin.kim \
    --region=ap-northeast-2 \
    --vpc-name=prod \
    --vpc-cidr=172.20.0.0/16 \
    --sg-name=prod-sg \
    --igw-name=prod-igw

2. create subnet

To create public subnet within VPC, use --is-public option.

1. create a subnet
2. create route table and add route to internet gateway
3. associate created subnet with created route table

python main.py configure-subnet \
    --profile-name=admin.kim \
    --vpc-name=prod \
    --subnet-name=pub-a \
    --cidr-substitute=100 \
    --availability-zone-postfix=a \
    --route-table-name=rt-pub-a \
    --is-public

To create private subnet within VPC, use --no-is-public option.

1. create a subnet
2. create a route table
3. associate created subnet with created route table

python main.py configure-subnet \
    --profile-name=admin.kim \
    --vpc-name=prod \
    --subnet-name=prv-c \
    --cidr-substitute=101 \
    --availability-zone-postfix=c \
    --route-table-name=rt-prv-c \
    --no-is-public

3. delete subnet

Delete objects in reverse order of their creation.

1. delete association between subnet and route table
2. delete the route table
3. delete the subnet

python main.py remove-subnet \
    --profile-name=admin.kim \
    --subnet-name=pub-a

4. delete VPC

Delete objects in reverse order of their creation.

1. detach internet gateway from VPC and delete it
2. delete security group
3. delete VPC

python main.py remove-vpc \
    --profile-name=admin.kim \
    --vpc-name=prod
