Method Details

profileFile

InstanceProfileCredentialsProvider.Builder profileFile(ProfileFile profileFile)

Configure the profile file used for loading IMDS-related configuration, like the endpoint mode (IPv4 vs IPv6).

By default, ProfileFile.defaultProfileFile() is used.

• profileFile(Supplier)

profileFile

InstanceProfileCredentialsProvider.Builder profileFile(Supplier<ProfileFile> profileFileSupplier)

Define the mechanism for loading profile files.

Parameters:

profileFileSupplier - Supplier interface for generating a ProfileFile instance.

See Also:

• profileFile(ProfileFile)

profileName

InstanceProfileCredentialsProvider.Builder profileName(String profileName)

Configure the profile name used for loading IMDS-related configuration, like the endpoint mode (IPv4 vs IPv6).

By default, ProfileFileSystemSetting.AWS_PROFILE is used.

staleTime

InstanceProfileCredentialsProvider.Builder staleTime(Duration duration)

Configure the amount of time before the moment of expiration of credentials for which to consider the credentials to be stale. A higher value can lead to a higher rate of request being made to the Amazon EC2 Instance Metadata Service. The default is 1 sec.

Increasing this value to a higher value (10s or more) may help with situations where a higher load on the instance metadata service causes it to return 503s error, for which the SDK may not be able to recover fast enough and returns expired credentials.

Parameters:

duration - the amount of time before expiration for when to consider the credentials to be stale and need refresh
