An attempt to create an Aurora instance in AWS via Terraform.

An Aurora Cluster in AWS via Terraform

This is an attempt to create a serverless Aurora cluster in AWS via Terraform. The Aurora cluster is placed in a private subnet and accessed via a Bastion in a public subnet.

Using Amazon Aurora Serverless v1: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless.html

Steps:

• Create a VPC, with 1 public subnet and 2 private subnets
• Create bastion
• Create a security group for SSH access for the bastion
• Create a security group for PostgeSQL access for the bastion?
• Create Aurora cluster
• Create a security group for PostgreSQL access to Aurora that the bastion will use
• Connect via pgAdmin

To connect with pgAdmin:

1. Open pgAdmin
2. Log in
3. Hit 'Add New Server'
4. Give it 'Name', i.e. 'aurora-spike'
5. Hit the 'Connection' tab
6. For 'Host name/address' use the output 'aurora_server_endpoint'
7. For 'Username' use the output 'master_username'
8. For 'Password' use the output 'mater_password'
9. Click 'Save password?'
10. Hit the 'SSH Tunnel' tab
11. Toggle 'Use SSH tunneling' to 'Yes'
12. For 'Tunnel host' use the output 'bastion_public_ip'
13. Leave 'Tunnel port' as '22'
14. For 'Username' use 'ec2-user'
15. Toggle 'Authentication' to 'Identity file'
16. For 'Identity file' browse to the location of the 'pem' file
17. Hit the 'Advanced' tab
18. Increase 'Connection timeout', i.e. 90
19. Hit 'Save'

You should be connected to your Aurora cluster! :)
