🤧 Hostan app

/ˈhʊsˌtan/ app

Hostan provides a set of Kubernetes primitives to easily and rapidly deploy apps on a cluster that uses services like databases, object storage, etc. "Hostan" is a Swedish word that translates to "the cough."

Todo

• Create README outlining the future functionality
• Implement CRD and controller for the App resource
• Implement CRD and controller for the Provider resource
• Create spec/protobuf file for the provider interface
• Create config maps and secrets for config upon reconciliation
• Add support for cronjobs
• Add support for explicit environment variable definitions
• Add validation hooks for providers
• Implement proper statuses
• Write a provider for SQL databases (using database/sql)
• Write a provider for redis
