Struct ProfileFileRegionProvider

Source 
pub struct ProfileFileRegionProvider { /* private fields */ }
Expand description

Load a region from a profile file

This provider will attempt to load AWS shared configuration, then read the region property from the active profile.

§Location of Profile Files

  • The location of the config file will be loaded from the AWS_CONFIG_FILE environment variable with a fallback to ~/.aws/config
  • The location of the credentials file will be loaded from the AWS_SHARED_CREDENTIALS_FILE environment variable with a fallback to ~/.aws/credentials

The location of these files can also be customized programmatically using ProfileFiles.

§Home directory resolution

Home directory resolution is implemented to match the behavior of the CLI & Python. ~ is only used for home directory resolution when it:

  • Starts the path
  • Is followed immediately by / or a platform specific separator. (On windows, ~/ and ~\ both resolve to the home directory.

When determining the home directory, the following environment variables are checked:

  • HOME on all platforms
  • USERPROFILE on Windows
  • The concatenation of HOMEDRIVE and HOMEPATH on Windows ($HOMEDRIVE$HOMEPATH)

§Examples

Loads “us-west-2” as the region

[default]
region = us-west-2

Loads us-east-1 as the region if and only if the AWS_PROFILE environment variable is set to other.

[profile other]
region = us-east-1

This provider is part of the default region provider chain.
