Modifying variables just for you
Since .docker.env is a common shared file you will not be able to make personal modifications on it. For this king of customizations you have .docker.override.env
.docker.override.env should be never committed since it is only for you and your environment. The usage is really simple. Just put in there the variables you want to override with the new value like in the original .docker.env file.
