Ask HN: How is your docker based production flow?

Hello, I've started to use docker and docker-compose recently and I've been enjoying so far!

Just wondering how everyone is using docker in their production environment, I am doing a side project to learn docker & django and basically what I do is:

git push -> webhook -> run tests -> tag images -> docker push image to docker hub.

Then I am using docker machine to an AWS instance (ec2), in which I connect and docker pull the images and then docker-compose up -d

This is probably not the best set up so I am open to suggestions / learn from you :)

Cheers
