Where is rails env defined

If you use these values, then Cloud 66 will replace them with a fixed random string of the specified length 10 is the default length. Using this, you can safely commit your env file to your git repository with the following content for example, then load it when you create your new application for concrete values. As mentioned earlier, Cloud 66 auto-generates a number of environment variables, which can be used in addition to those that you define.
