Module for an EC2 instance

[davidkelliott]

User Story

A user of the platform wants to quickly spin up an EC2 with sensible defaults. Then have the ability to modify this as needed so that it can work in multiple scenarios

Replace example code with whatever is built.

Don't reinvent the wheel, just borrow the Hashicorp wheel and paint it with MOJ colours

Can we re-use / lift the terraform from DSO that they use for their VM module?

The outcome is for people who want to quickly spin up an EC2 to eg test something - should be vanilla

User Type(s)

MP Platform member user

Value

Saves users times and helps improve security and coding standards by using sensible defaults.

Questions / Assumptions / Hypothesis

If we create a module to build an EC2 And give it sensible defaults And the option to override the defaults Then we will have an EC2 module that is suitable for both quick usage and for applications

Proposal

Create an EC2 Terraform Module

There's a module available in modernisation-platform-environments used by the Equip team. I think it's just a fork of a Hashicorp module, though. Is this something that we want to actually build from scratch, or would it be enough to see what MOJ-specific customisations we'd need to make to the Hashicorp module? https://github.com/terraform-aws-modules/terraform-aws-ec2-instance

Very basic version of an ECS build added. Included bits that might not be needed and added a role for access purposes. Works OK via the terminal.
