CF Platform Specific Deployment for Core module

[dzahariev]

Background

Service Manager exists outside of all platforms, as it is consumable (reached) through it’s REST API.
Anyway it need to be deployed somewhere (on some infrastructure/platform) and we tend to support at least 2 options - K8S and CF as host platforms for SM.
The implementation is separated on 2 parts:
Core module - that take cares for Business logic implementation including:

• Initial configuration through environment
• REST API implementation
• Domain and Data model
• Persistency handling through provided configuration to persistency provider
• Extensibility capabilities
• Healthcheck endpoint

Platform specific module - that take cares for packaging and platform specific configuration like:

• Platform specific deployment details - CPU, RAM, Buildpack, VM type, …
• Platform specific packaging details - archive or image preparation
• Platform specific provisioning and deployment scripts ensuring HA and Blue/Green deployment
• Platform specific health check requirements to the core module
• Persistency provider configurations
• Identity management provider configurations
• Registration of Custom URL for the deployed service

Example with Go Application packaging for CF can be seen on:

Objective

Prepare CF Platform dependent module.

Acceptance Criteria

• I can build (prepare deployable) with a script that is included in the repository
• README document with deployment process including preconditions, installation steps and configuration details is included
• Following the steps I can deploy and start the SM Core module in CF environment
