Future Scope

• Automatic tls private key creation to use with key_pair argument of the resource or to pass on the key pair resource name which should exist before running terraform apply.
• Spawn instance in an autoscaling group using launch template and launch config.
• Generating sentry key from the bootstrap script. Right now, It is hardcoded.
• Adding the capability to pass subnet groups, It will give modularity to use custom VPC.
• Creation of security group and attaching it with the instance.
• Storing Terraform state backend in s3 with DynamoDB locking.
• Getting the value of sentry initial username and password from the root module.
• Static test analysis of the code through terratest or tftest.

Note:

• Kindly change the secret key and the bootstrap username/password. Also, Current details including key mentioned is a "dummy text" and does not assosiate with any service.
