Usage
The scheme for this provider is env. Usage looks like the following:
env:NAME_OF_ENVIRONMENT_VARIABLE
To use default values when the environment variable has not been set, you can include a suffix to specify it:
env:NAME_OF_ENVIRONMENT_VARIABLE:-default_value
Environment variables must match the following regular expression. That is, they must be at least one character, start with a letter or underscore, and can only include letters, numbers, and underscores.
^[a-zA-Z_][a-zA-Z0-9_]*$
