Grammar for deployment architecture model

The deployment architecture model can be defined using a grammar, which allows for a textual specification that enhances the understanding of the model. For example, you can specify a deployment model using the following syntax, which includes elements such as applications, services, containers, deployments, regions, and clusters.

Deployment model{
    applications {
        ->  name: app1,
            image: "hhtp://docker-image/latest",
            port: 8000,
            cpu_required: 10m,
            memory_required: 100Mi,
            domain_model: "library_model"
    }

    services {
        ->  name: service1, port: 80,
            target_port: 8000,
            protocol: TCP,
            type: lb,
            app_name: app1
    }

    containers {
        ->  name: container1,
            app_name: app1,
            cpu_limit: 500 m,
            memory_limit: 512Mi
    }

    deployments {
        ->  name: deployment1,
            replicas: 2,
            containers: [container1]
    }

    regions {
        ->  name: us-east1
    }

    clusters {
        ->  public_cluster
            name: cluster1,
            number_of_nodes: 3,
            provider: google,
            config_file: "file",
            services: [service1],
            deployments: [deployment1],
            regions: [us-east1],
            net_config: True
    }
}

Once the deployment textual model is defined, you can parse it and obtain the B-UML model as follows.

from besser.BUML.notations.deployment import buml_deployment_model
from besser.BUML.metamodel.deployment import DeploymentModel

# deployment.txt contains the textual definition of the deployment architecture
deployment_model: DeploymentModel = buml_deployment_model(deployment_textfile="deployment.txt")

This deployment_model is a B-UML model that you can use in BESSER, for example, to generate the Terraform code to automate the deployment using our Terraform Generator
