Nautobot on AWS

This is a brief summary of setting up Nautobot on AWS. I used Nautobot 1.1.3, but it should not vary too much when using different versions. It assumes some familiarity with Nautobot and AWS. Pretty much all of the AWS cli commands are the bare minimum to stand up some version of this and only show creating one resource if multiple identical resources are needed, you should add tags and consider your needs around sizing, redundancy, etc. The end result is a basic Nautobot deployment. It is not doing any scaling, just one http server and one celery worker.

Starting infrastructure and configurations

• a VPC containing 2 private and 2 public subnets, with each pair of subnets in two different AZs
• routes configured back to your on premise network from the VPC
• an ec2 bastion host with an interface on the private subnet for local access to EFS and RDS
• a nautobot_config.py file that has been updated to meet your needs
• a nautobot.env file that has been updated to meet your
