converter-package 2.0

This converter library is able to transform the ACCORDION application model to K3s configuration files

Converter

Converter is a subcomponent of the ACCORDION platform. It is being used by the Orchestrator and Lifecycle Manager components in order to translate the application model to K3s configuration files, action models, workflow models and matchmaking models

Installation

pip3 install converter-package==2.0

1. Parse Intermediate Model

nodelist, imagelist, application_version = Parser.ReadFile(jsonResponse)

2. Create the namespace that describes the appInstanceInfo

 application_instance = ID.generate_k3s_namespace(name, application_version, randomApplicationIntanceID())

3. How to generate matchmaking model

matchmaking_model = MatchingModel.generate(nodelist, application_instance)

4. Generate namespace and secrets files for Kubernetes

namespace_yaml = Converter.namespace(application_instance)
secret_yaml = Converter.secret_generation(json_base64_string, application_instance)

5. Generate deployments, persistenv volumes and services files for Kubernetes

deployment_files, persistent_files, service_files = Converter.tosca_to_k8s(nodelist, imagelist,
                                                                                   application_instance, minicloud,
                                                                                   externalIP, gpu_list)

!!! Warning: gpu_model is an optional parameter. Since one or more GPU names may be given to Converter, the parameter has to be a list that would contain application components along with the required GPUs

6. Generate the action model

actions_set = ActionModel.generate(nodelist, application_instance)

7. Generate the workflows model

workflows_set = WorkflowModel.generate(nodelist, application_instance)

8. Scale out

json_base64_string, url, name = online_selector('plexus')
intermediate_model = callAppBucket(json_base64_string, url, name)
deployment = Converter.scale_out_to_k8s(componentInfo, intermediate_model)

More on Usage

DeployInterface.py is an example of usage for the case of deployment. There is also the ScaleOutInterface.py that presents how to use Converter to create scale out files for ACCORDION, it is available on the ACCORDION's Gitlab
