I'm using something like:
```def say_hello():
    container = CreateContainer(
        image_name="nonexistentname",
    )
    StartContainer(container_id=container, docker_server_url="arandomtext")
    WaitOnContainer(container_id=container)```
and it's always successful. Even with correct data i don't see my image executed

hey Marco, just to clarify, do you provide any commands in CreateContainer task?

It's an image that automatically do things on start(python script)

It looks like you’ve got those in a function and not a flow? You’re just creating instances of classes, not running them.

Take a look at the docs at <https://docs.prefect.io/core/getting_started/first-steps.html#task-classes> — you initialize the Task classes then they call each other in a flow-context
