If you do not follow this naming convention the provider will not work and throw.In the above the prefix is used for the keys path and can also be set with CONSUL_PREFIX (provide an empty string to the prefix if you wish to just use the env var)The CONSUL_HOST env var is used for the host to talk to consul and defaults to localhostThe CONSUL_PORT env var is used for the port to talk to consul and defaults to 8500The http_module is dynamic and you can specify your own if you choose to do so. Just implement the HTTP behaviour and make your implementation return an {:ok, json_body_binary_string} as per the mojito example which will be the fallback. You might have to deal with coercing the input keyword list for the mojito arguments to support the client you are using, as well. You also need to set config :consul_config_provider, :http_module, Client.YourClient pointing to your client in your configs.Dependency-related configs are namespaced with their own application name while other configs use the input app_name for their namespace","ref":"readme.html#installation","title":"ConsulConfigProvider - Installation","type":"extras"}]
