## Content overview
This repo controls the deployment of an application module.
It consists of the following core elements:
### main.tf
This file has the basic components for EC2 instances.
- Private subnet and route table association
- EC2 instances
- Security group for the EC2 instance
### variables.tf
Input data for resources within this repo.
### tests/e2e_test.py
Code and resource tester with mock data. It can be expanded by adding further definitions to the unit.
### rds.tf
Deploys an RDS instance as the Tableau Internal backend instance.
## User guide
### Prepare your local environment
This project currently depends on:
* drone v0.5+dev
* terraform v0.11.1+
* terragrunt v0.13.21+
* python v3.6.3+
Please ensure that you have the correct versions installed (it is not currently tested against the latest version of Drone)
### How to run/deploy
To run tests using the [tf testsuite](https://github.com/UKHomeOffice/dq-tf-testsuite):
```shell
drone exec --repo.trusted
```
To launch:
```shell
terragrunt plan
terragrunt apply
```
## FAQs
### The remote state isn't updating, what do I do?
If the CI process appears to be stuck with a stale `tf state` then run the following command to force a refresh:
```
terragrunt refresh
```
If the CI process is still failing after a refresh look for errors about items no longer available in AWS - say something that was deleted manually via the AWS console or CLI.
To explicitly delete the stale resource from TF state use the following command below. *Note:*```terragrunt state rm``` will not delete the resource from AWS it will unlink it from state only.
```shell
terragrunt state rm aws_resource_name
```
