Started using Appliku for my own needs (which was the plan all along), I found that MVP is missing crucial features: Databases.
So, I am back to coding. Right now I am implementing functionality for having Plugins: Databases (Postgres, Redis, RabbitMQ) running inside docker-compose along with the application processes.
The goal of having databases as docker-compose is to run non-production environments, such as dev/staging environments.
For production environments, I plan to integrate Digital Ocean's Managed Postgres provisioning via API.
