CloudHarness is a base infrastructure facilitator for micro-service based applications deployed on Kubernetes.

What building your cluster application with CloudHarness gives to you:

• Common framework and utilities to develop and deploy micro-service application
  • REST-API scaffolding building based on OpenApi (Python-Flask)
  • Helm chart automatic generation
  • Automatic build and push of images
  • Continuous deployment script generation (Codefresh)
• Prebuilt support applications and shared library to:
  • Log in and user management - based on Keycloak
  • Submit batch and asynchronous workflows - based on Argo
  • Orchestrate Micro-services - based on Kafka
