1 // Package config provides utilities for loading configuration from multiple 2 // sources that can be used to configure the SDK's API clients, and utilities. 3 // 4 // The config package will load configuration from environment variables, AWS 5 // shared configuration file (~/.aws/config), and AWS shared credentials file 6 // (~/.aws/credentials). 7 // 8 // Use the LoadDefaultConfig to load configuration from all the SDK's supported 9 // sources, and resolve credentials using the SDK's default credential chain. 10 // 11 // LoadDefaultConfig allows for a variadic list of additional Config sources that can 12 // provide one or more configuration values which can be used to programmatically control the resolution 13 // of a specific value, or allow for broader range of additional configuration sources not supported by the SDK. 14 // A Config source implements one or more provider interfaces defined in this package. Config sources passed in will 15 // take precedence over the default environment and shared config sources used by the SDK. If one or more Config sources 16 // implement the same provider interface, priority will be handled by the order in which the sources were passed in. 17 // 18 // A number of helpers (prefixed by “With“) are provided in this package that implement their respective provider 19 // interface. These helpers should be used for overriding configuration programmatically at runtime. 20 package config 21
