AWS ElasticBeanstalk failed to deploy Django/Postgres app

Question

I'm having a hard time deploying my app built with Django, Postgres, DjangoQ, Redis and ES on AWS Elastic Beanstalk, using docker-compose.yml.

I've used EB CLI (eb init, eb create) to do it and it shows the environment is successfully launched but I still have the following problem.

1. On the EC2 instance, there is no postgres, djangoq and ec containers built like it says in the docker-compose file as below. Only django, redis and ngnix containers are found on the ec2 instance.

2. The environment variables that I specified in the docker-compose.yml file aren't being configured to the django container on EC2, so I can't run django there.

I'm pretty lost and am not sure where to even start to fix the problems here.. Any insight will be very much appreciated..

can you confirm that your environment variables are being used correctly? A common mistake with EB and docker-compsoe is that it is assumed that your.env file works the same way in EB as it does in docker-compose when it does not. I have made that mistake before. Check out the docs https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker.container.console.html#docker-env-cfg.env-variables
