Я пытаюсь использовать docker-compose
для создания своих сервисов Flask/Celery/Redis.
Здесь мой docker-compose.yml
:
flask:
build: .
command: "python3 app.py"
ports:
- '5000:5000'
links:
- redis
volumes:
- .:/usr/src/app:ro
celery:
build: .
command: "celery -A app.celery worker --loglevel=info"
volumes:
- .:/usr/src/app:ro
redis:
image: redis
ports:
- '6379:6379'
Когда я запускаю этот docker-compose
, оба фласка и Redis начинают нормально и функционируют, как ожидалось. Что касается сельдерея, отчеты Docker: flaskcelery_celery_1 exited with code 1
, без дополнительной информации.
Если я запускаю свои три службы без Docker и запускаю Celery с помощью celery -A app.celery worker --loglevel=info
, мое приложение функционирует нормально.
Дополнительная информация, если необходимо:
Dockerfile: (этот образ устанавливает requirements.txt
и на сборку)
FROM python:3.5-onbuild
EXPOSE 5000
requirements.txt:
flask==0.11.1
celery==3.1.23
docker-compose up
вывод:
