# A utility tool to create .env files
[](https://travis-ci.org/sobolevn/dump-env) [](https://coveralls.io/github/sobolevn/dump-env?branch=master) [](https://https://pypi.org/project/dump-env/) [](http://dump-env.readthedocs.io/en/latest/?badge=latest)
dump-env takes an .env.template file and some optional environmental variables to create a new .env file from these two sources. No external dependencies are used.
## Why?
Why do we need such a tool? Well, this tool is very helpful when your CI is building docker (or other) images. [Previously](https://github.com/wemake-services/wemake-django-template/blob/6a7ab060e8435fd855cd806706c5d1b5a9e76d12/%7B%7Bcookiecutter.project_name%7D%7D/.gitlab-ci.yml#L25) we had some complex logic of encrypting and decrypting files, importing secret keys and so on. Now we can just create secret variables for our CI, add some prefix to it, and use dump-env to make our life easier.
## Quickstart
This quick demo will demonstrate the main and the only purpose of dump-env:
`bash $ dump-env --template=.env.template --prefix='SECRET_ENV_' > .env `
This command will:
take .env.template
parse its keys and values
read and all the variables from the environment starting with SECRET_ENV_
remove this prefix
mix it all together, where environment variables could override ones with the same name from the template
sort keys in alphabetic order
dump all the keys and values into the .env file
## Installation
`bash $ pip install dump-env `
