在ibm bluemix区块链服务上部署BNA文件

Question

I am trying to deploy a BNA file on the IBM bluemix blockchain service. I have obtained the BNA file from the composer playground and i could not find a way to push that file on bluemix blockchain service.
I have tried this tutorial but they are trying to make a chaincode and then deploying it on the blockchain service of bluemix.
Why do i have to create a chaincode for deploying? can't i just push the models and javascript transaction processor functions and then use it via a REST API from the bluemix blockchain service.
A step by step process for deploying the BNA file(obtained from composer playground) on the bluemix blockchain service would be much appreciated.
Regards

Answer 1

The link you provide is for Go Lang chaincode, not a Composer Business Network (BNA). I would suggest the following link, Fabric composer integration with Bluemix blockchain service .

Answer 2

You're supposed to deploy a chaincode, to IBM-Blockchain, not a .bna file. To link your .bna file with the deployed code, you'd need to download the connections settings of your blockchain (which can be found at Overview/Connection Profile) and put it at the same directory of your .bna file.

The image below says where you can find the connections settings:
