我有一个分布式Dockerized应用程序，有四个服务：Django，Postgres，Caddy。这三个都是私有托管在Docker Hub上的。我试图让他们通过Docker Cloud与DigitalOcean节点一起运行。问题出在Django服务上，该服务与Gunicorn一起运行。
当我尝试启动该服务时，出现以下错误：
[django-1]2017-11-27T05:58:33.944903048Z Postgres is unavailable - sleeping
[django-1]2017-11-27T05:58:35.176033131Z Postgres is up - continuing...

我不确定问题究竟是什么。 Gunicorn在gunicorn.sh开始，看起来像这样：
#!/usr/bin/env bash
set -o errexit
set -o pipefail
set -o nounset
python /app/manage.py collectstatic --noinput
/usr/local/bin/gunicorn config.wsgi -w 4 -b 0.0.0.0:5000 --chdir=/app
当我在本地构建和运行我的容器时，我没有收到上述错误。
Django容器的我的Dockerfile如下所示：
FROM python:3.5
ENV PYTHONUNBUFFERED 1
RUN groupadd -r django \
&& useradd -r -g django django
# Requirements have to be pulled and installed here, otherwise caching won't work
COPY ./requirements /requirements
RUN pip install --no-cache-dir -r /requirements/production.txt \
&& rm -rf /requirements
COPY ./compose/production/django/gunicorn.sh /gunicorn.sh
RUN sed -i 's/\r//' /gunicorn.sh
RUN chmod +x /gunicorn.sh
RUN chown django /gunicorn.sh
COPY ./compose/production/django/entrypoint.sh /entrypoint.sh
RUN sed -i 's/\r//' /entrypoint.sh
RUN chmod +x /entrypoint.sh
RUN chown django /entrypoint.sh
COPY ./compose/production/django/celery/worker/start.sh /start-celeryworker.sh
RUN sed -i 's/\r//' /start-celeryworker.sh
RUN chmod +x /start-celeryworker.sh
COPY ./compose/production/django/celery/beat/start.sh /start-celerybeat.sh
RUN sed -i 's/\r//' /start-celerybeat.sh
RUN chmod +x /start-celerybeat.sh
COPY . /app
RUN chown -R django /app
USER django
WORKDIR /app
ENTRYPOINT ["/entrypoint.sh"]
我的Docker Compose文件的相关部分（在Docker Cloud Django服务设置中复制）如下所示：
services:
django:
build:
context: .
dockerfile: ./compose/production/django/Dockerfile
depends_on:
- postgres
- redis
env_file: .env
command: /gunicorn.sh
任何人都可以帮我指出正确的方向吗？谢谢！
