Issues with COS (S3) Samples about streamsx.objectstorage

[alexpy11]

@natashadsilva documentation and samples are still work in progress.
The following picture explains mapping of object storage service credentials on an object storage operator credentials.

IAM support for authentication will be available in an upcoming toolkit version. It is currently on iss#9-stocator-based-impl branch.

Thanks. So the master branch currently does not support it?
The samples refere to ObjectStorage-AccessKeyID", ObjectStorage-SecretAccessKey and ObjectStorage-Endpoint. There is no AccesskeyId or AccessKey in the credentials. I checked the samples in the 9-stocator-based-impl branch and they are the same names. Accesskey and AccessKeyid are not in the IAM credentials. Will the samples be updated to match the names in the credentials map?

Yes, the master branch does not support it, because the toolkit has been developed and released long time before IBM COS introduced IAM.
Samples are still valid for S3 object storages, where the user has the accesskey and secretaccesskey.
There is a new sample for IAM credentials available.
IBM COS S3 supports both authentication methods, but it seems that not every user has the chance to get the accesskey and secretaccesskey credentials. It depends when and how the IBM COS S3 service has been created.

@natashadsilva the following sample on iss#9-stocator-based-impl branch provides Scan, Source and Sink examples with IAM-based authentication: https://github.com/IBMStreams/streamsx.objectstorage/blob/iss%239-stocator-based-impl/samples/com.ibm.streamsx.objectstorage.sample/com.ibm.streamsx.objectstorage.sample/S3DownloadIAMAuthSample.spl
