# Configuring environment variables and secret keys
|
|
|
|
Take a look at `Envfile`. This file lists all the `ENV` variables we use and
|
|
provides a fake default for any missing keys.
|
|
|
|
The [backend guide][backend_guide] will show you how to get free API keys for
|
|
additional services that may be required to run certain parts of the app.
|
|
|
|
To set up keys for your local instance of DEV, you'll need to create an
|
|
`application.yml` file. You can do this by copying the file called
|
|
`sample_application.yml` in the `config` directory:
|
|
|
|
```shell
|
|
cp config/sample_application.yml config/application.yml
|
|
```
|
|
|
|
Then, add each key you need to the `application.yml` file. For example, if
|
|
you're setting up GitHub authentication:
|
|
|
|
```shell
|
|
GITHUB_KEY: "SOME_REAL_SECURE_KEY_HERE"
|
|
GITHUB_SECRET: "ANOTHER_REAL_SECURE_KEY_HERE"
|
|
```
|
|
|
|
(Don't worry, your `application.yml` file is ignored by git)
|
|
|
|
If you are missing `ENV` variables on bootup, the [envied][envied] gem will
|
|
alert you with messages similar to
|
|
`'error_on_missing_variables!': The following environment variables should be set: A_MISSING_KEY.`.
|
|
|
|
Only certain features require "real" keys, so you may be able to add them as you
|
|
work on different areas of the application.
