Method Detail

discover

public DefaultsMode discover(Region regionResolvedFromSdkClient)

Discovers the defaultMode using the following workflow: 1. Check if it's on mobile 2. If it's not on mobile (best we can tell), see if we can determine whether we're an in-region or cross-region client. 3. If we couldn't figure out the region from environment variables. Check IMDSv2. This step might take up to 1 second (default connect timeout) 4. Finally, use fallback mode
