Bug: HealthcheckWaitStrategy returns error with DockerCompose

[reyescabello]

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: 40s

Traceback:

Traceback (most recent call last):
  File "<path>/test.py", line 9, in <module>
    compose.start()
  File "testcontainers/compose/compose.py", line 303, in start
    strategy.wait_until_ready(container)
  File "testcontainers/core/wait_strategies.py", line 487, in wait_until_ready
    health = wrapped.attrs.get("State", {}).get("Health", {})
             ^^^^^^^^^^^^^
AttributeError: 'ComposeContainer' object has no attribute 'attrs'
