tf-nano

Create t2.nano instances in AWS EC2 with Terraform

Easily substitute t2.nano for any other instance type.

Ideal base layer for creating deployment instances with Distelli.

Features

• cloud-config / cloud-init template integration with Terraform for headless configuration of Distelli agent on your instances

• ability to bootstrap agent onto instances than are behind NAT

• instances are created in standalone, project based, VPC and subnet

• single or multi-region instance creation via terraform variables file and count

• scalable to N instances (limit is defined by your AWS account limits)

• in-project ssh key to access instances with the operator's system ssh-agent (optional)

• locked down security group: tcp/22,80,443 are the only open public facing ports

• Ubuntu 16.04, us-west-2, HVM, SSD instance by default

Usage

• git clone https://github.com/cmosetick/tf-nano.git

• cd tf-nano

• change your EC2 instance type, AMI, or region as desired in variables.tf

• create terraform.tfvars file using the example file as basis. Input your AWS API credentials in the file. Note that this file name is in .gitignore

• create an ssh key using the following format:
  ssh-keygen -t rsa -b 2048 -P '' -f files/cmosetick-terraform -C 'tfnano@demo'

• add the new key to the operator's ssh agent session:
  ssh-add files/cmosetick-terraform ; ssh-add -l
  If you change the name of your key, make sure you add a line to .gitignore with the name

• terraform plan

• terraform apply

Caveats

• If you select an AMI that does not have cloud-init package installed, your instances will be created, but you will not have an agent installed from the included cloud-config template. Most distros today include cloud-init.
