Terraform AWS RDS and Redis Module

This private module is to quickly build the external services (RDS Postsgre DB and Redis instances) on AWS required deploying Terraform Enterprise on Docker.

Once the provision is completed, it will print out the following outputs. For example:

postgres_server_details = {
  "database_name" = "tfedb"
  "hostname" = "postgres-instance.xxxxxxxx.ap-southeast-2.rds.amazonaws.com"
  "port" = 5432
}
redis_cache_details = {
  "hostname" = "redis-instance.xxxxxxx.0001.apse2.cache.amazonaws.com"
  "port" = 6379
}
region = "ap-southeast-2"

With these outputs, test the connectivity to the external services within the the same VPC. For example:

Postgres

$ PGPASSWORD=$PASSWORD psql -h postgres-instance.xxxxxx.ap-southeast-2.rds.amazonaws.com -U postgres -c "\l"
                                  List of databases
   Name    |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
 postgres  | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
...
(5 rows)

Redis

$ redis-cli -h redis-instance.ls32dv.0001.apse2.cache.amazonaws.com -p 6379 ping
PONG

Next, configure the Docker Compose YAML file to specify the hostnames of the PostgreSQL and Redis instances. Then, deploy the Terraform Enterprise Docker setup on an EC2 instance within the same VPC.
