使用Traefik和Docker错误在EBS弹性Beanstalk服务中提供Django应用服务：502错误网关

如何解决使用Traefik和Docker错误在EBS弹性Beanstalk服务中提供Django应用服务：502错误网关

我正在尝试使用带有TravisCI，Docker的Django Cookiecutter（https://github.com/pydanny/cookiecutter-django）以及使用Traefik作为路由器来部署多容器应用程序。我已经通过绿色健康检查成功地将应用程序部署到了AWS中的EBS（弹性Beanstalk服务）应用程序。我当前遇到的唯一问题是，如果我尝试访问分配的主机名或域，则会收到502 bad gateway错误。我怀疑traefik.yml文件中的配置错误或Dockerrunaws.json文件中的端口映射错误。请帮助我找到错误。

以下是配置：

请注意，“ myhostname.com”是指我的实际DNS主机名，“ myusername”是指我的实际docker集线器用户名。

我还使用Route 53将带有A名称记录的主机名映射到我的ELB实例。

Traefik Dockerfile

FROM traefik:v2.0
RUN mkdir -p /etc/traefik/acme
RUN touch /etc/traefik/acme/acme.json
RUN chmod 600 /etc/traefik/acme/acme.json
copY ./compose/production/traefik/traefik.yml /etc/traefik

Django相关设置：

ALLOWED_HOSTS=.myhostname.com
DJANGO_SECURE_SSL_REDIRECT=False

其余的Django环境设置已经在我的ELB的环境属性中。
