[Bug] Klue looks for non-existent infrastructure_description.json when running with --skip-tracer

[Mapalmeira]

When running the emulator with the --skip-tracer flag, Klue attempts to read infrastructure_description.json from /tmp instead of the data_path provided via CLI.

Command executed:

./execute-emulation.sh \
  --sim \
  --use-cluster minikube \
  --data-path ../data-example \
  --use-karpenter \
  --nodepool-path ../data-example/nodepools.yaml \
  --skip-tracer

Error thrown:

Traceback (most recent call last):
  File "<dir>/emulador-klue/src/main.py", line 95, in <module>
    main_instance.run_manager()
  File "<dir>/emulador-klue/src/main.py", line 64, in run_manager
    manager = Manager(karpenter=self.karpenter, infrastructure=self.infrastructure, workload=self.workload)
  File "<dir>/emulador-klue/src/manager.py", line 32, in __init__
    self.infrastructure_manager = InfrastructureManager(f"{data_path}/infrastructure_description.json", karpenter, infrastructure)
  File "<dir>/emulador-klue/src/infrastructure/manager.py", line 25, in __init__
    with open(data_path, 'r', encoding="utf-8") as file:
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/infrastructure_description.json'

However, infrastructure_description.json does exist inside the directory passed via --data-path.

In src/main.py, the Manager is instantiated without passing data_path:

def run_manager(self):
    manager = Manager(karpenter=self.karpenter, infrastructure=self.infrastructure, workload=self.workload)
    manager.run(

In src/manager.py, the constructor defaults to:

def __init__(self, data_path='/tmp', karpenter=True, infrastructure=None, workload=None):

Therefore, Manager always receives data_path="/tmp".
