We do not run dbs as containers other than for dev or testing.
'convox services add postgres' and 'convox services add redis' provisions RDS and Elasticache respectively.
For example SNS. Would convox ever support terraform/cloudformation for an App, or would you add SQS service in convox, then create SNS outside of convox, and then join them together somewhere else?
Is a thing.
Automatic provisioning services should be easy.
Your rack and all your apps and services are CloudFormation stacks. We favor CloudFormation over terraform for the same reason, it's a managed service.
The dream is fully automated provisioning of everything you want inside a single AWS account and VPC.
Then you can peer this VPC with another to keep linking things.
The framework is open source so it's pretty easy for us or anyone to add more services when requested. SES would be a good one next.
