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.
