• What Is the Docker .env File and How Do You Use It? - The New Stack

  When you deploy Docker containers, you will oftentimes have to add customized variables. Those variables could include all sorts of information, including usernames, passwords, database names, etc. Of course, you can always hard code those variables into the container manifest but that is widely considered a security issue. On top of that, if you’re deploying similar containers over and over again, it’s not exactly efficient having to re-type all of that information.

  To solve these types of problems, most developers opt to go with the .env file. Essentially, an .env file is a list of key pair values that set specific variables for a container deployment. So, instead of having to code those variables into the manifest itself, you add them to an .env file and when you run docker-compose up -d, the variables will be applied from within the .env file (“env” being short for environment variables).
