🛠️ Development

Using KCL Schemas

# Import main package
import provisioning.main as prov

# Define infrastructure
server: prov.ServerConfig = {
    name = "web-01"
    plan = "1xCPU-2GB"
    zone = "de-fra1"
    operating_system = "ubuntu-22.04"
}

# Define workflow
workflow: prov.BatchWorkflow = {
    name = "deploy_servers"
    operations = [
        {
            type = "server_create"
            servers = [server]
        }
    ]
}

Validation

All configurations are validated at:

1. Schema Level - Type checking and constraint validation
2. Semantic Level - Cross-schema relationship validation
3. Execution Level - Runtime validation before execution
