Docker image across dev/qa/prod environment

Hi All,

One of advantage of using common image across all environments is that the same image that was tested in QA will reach the production environment with the same behavior.

The difference in the configuration of the service/application across envs could be manage by creation of parameterized container with using of env vars

What about situation when the image of application itself differs for example because of code instrumentation?
