title: docker-compose, run a script after container has started?
body: <p>I have a service that I am bringing up through Rancher via docker-compose. The issue I am running into is that I need to set a password after the container has been deployed.</p>
  
  <p>The way rancher secrets work, is that I set my secret in and rancher will mount a volume on my container with a file containing my secret. I was hoping to be able to execute a script to grab that secret, and set it as a password on my config file.</p>
  
  <p>I don't believe I have a way to get that secret in through the Dockerfile as I don't want the secret to be in git, so I'm left looking at doing it via docker-compose.</p>
  
  <p>Does anyone know if this is possible?</p>
