Bug: HealthcheckWaitStrategy returns error with DockerCompose #905
Description
Describe the bug
When applying a 'waiting_for' to a DockerCompose object with a HealthcheckWaitStrategy, it returns an AttributeError: “ComposeContainer” object has no attribute “attrs”.
To Reproduce
import os
from testcontainers.compose import DockerCompose
from testcontainers.core.wait_strategies import HealthcheckWaitStrategy
BASE_DIR = os.path.dirname(__file__)
compose = DockerCompose(context=BASE_DIR, compose_file_name = "docker-compose.yml")
compose.waiting_for({"web": HealthcheckWaitStrategy().with_startup_timeout(60)})
compose.start()docker-compose.yml:
version: '3.8'
services:
web:
image: nginx
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost"]
interval: 30s
timeout: 10s
retries: 3
start_period: 40sTraceback:
Traceback (most recent call last):
File "<path>/test.py", line 9, in <module>

File "testcontainers/compose/compose.py", line 303, in start
strategy.wait_until_ready(container)

health = wrapped.attrs.get("State", {}).get("Health", {})
