title: Using Vault with docker-compose file
body: <p>Currently I am using docker-compose file to setup my dev/prod environments. I am using environment variables to store secrets, database credentials etc. After some search, I found out that Vault can be used to secure the credentials. I tried couple of basic examples with vault, but still I have no idea of how to use Vault with a docker-compose file. Can someone point me to a correct way. If Vault is not a good solution with docker-compose, what are the mechanisms I could use to secure credentials rather than storing them in environment as plain text.</p>
