  • {module_name}_cache_auth_token – The auth token/password of the cluster.
  • {module_name}_cache_host – The host to contact to access the cluster.

In the modules reference, the {module_name} would be replaced with cache

The permission list can optionally have one entry which should be a map for renaming the default environment variable names to a user-defined value:

links:
  - db:
      - cache_host: CACHEHOST
        cache_auth_token: CACHEPASS

If present, this map must have renames for all 2 fields.
