View Source ExAws.Config (ExAws v2.5.3)

Generates the configuration for a service.

It starts with the defaults for a given environment and then merges in the common config from the ex_aws config root, and then finally any config specified for the particular service.

Refreshable fields

Some fields are marked as refreshable. These fields will be fetched through the auth cache even if they are passed in as overrides. This is so stale credentials aren't used, for example, with long running streams.

This behaviour must be explicitly enabled by passing refreshable: true as an option to Config.new/2

Builds a complete set of config for an operation.

  1. Defaults are pulled from ExAws.Config.Defaults
  2. Common values set via e.g config :ex_aws are merged in.
  3. Keys set on the individual service e.g config :ex_aws, :s3 are merged in
  4. Finally, any configuration overrides are merged in
