Channel creation using fabric-admin-sdk

[adityajoshi12]

I wanted to use this sdk in my application to be able to create channels on the runtime and I was going through the testcases to understand how to use this sdk. I found that in the testcase we are using packages that are internal to this project, which makes it difficult to use this sdk in the application.

fabric-admin-sdk/test/e2e_test.go

Line 17 in d480efd

"github.com/hyperledger/fabric-admin-sdk/internal/configtxgen/genesisconfig"

Also will there be any high level API that support the creation of configtx programatically. This will remove the dependency of the Configtx.yaml and channel blocks can be generated using the sdk.

An internal to this project, which makes it difficult to use this sdk in the application.

@adityajoshi12 could you please more specific about why the internal package makes difficult in your case?

remove the dependency of the Configtx.yaml?

if we don't have a config tx yaml... there seems lots of input values into the function for generate the block right? I am confused a little. hence need a more specific/clear description.

I am trying to create channel using the sdk in my application, now in order to create/access the profile profile, err = genesisconfig.Load("ChannelUsingRaft", "./") I need to access the genesisconfig package which i can't access since it's a internal package.

Other part: if there would be some sort of function that create the genesis block required to create channel. This kind of feature is available in legecy fabric-sdk-java here. This will allow channel creation without the need of configtx file and make it indepenent.

  currently the admin-sdk try to keep same behavior with cli which read a config profile for block generation. IMO from code structure point of view seems no harmful to make the packages from internal to publish.
  wdyt?

Also, this align with the initial idea of @denyeart mentioned here

[SamYuan1990]

let's wait for @denyeart 's feedback.
I suppose @adityajoshi12 your point is that we just make the channel config package from internal to public for fabric admin sdk repo and replace with https://github.com/hyperledger/fabric-config ?

[adityajoshi12]

I am looking for two things:

1. Moving the configtxgen out of internal pkg. This can be immediate fix.
2. The other ask would be to have a high level API that allows the channel creation without the need of configtx.yaml file.

Hi @SamYuan1990 , it been a long, we didn't had any update on this.

[SamYuan1990]

I am waiting for other maintains feedback as well. @denyeart and @bestbeforetoday what do you think?

[SamYuan1990]

I listed this discussion on fabric contributor meeting. https://wiki.hyperledger.org/display/fabric/Contributor+Meetings+2024

[SamYuan1990]

@adityajoshi12 , here is feedback from contributor meeting.
#187 (reply in thread) the sample here as you mentioned is node sdk but the link is java and not one for channel creation.
So, we want to request more details.

at the meanwhile, as fabric-config project, if publish the package really benefits people, we are happy to make it. Hence I am going to make a PR, but we should evaluate if it's good enough to public.

[adityajoshi12]

I have updated the link above. The requirement here is to create a channel programatically using the admin-sdk. Currently admin-sdk has capability to create the channel using the Configtx.yaml file, but I would be interested in leveraging admin-sdk create channel using the high level API, that will avoid us from the need of Configtx.yaml file.

The other requirement is to make the configtxgen pkg out of internal pkg so that functions like genesisconfig.Load("ChannelUsingRaft", "./") can be accessed outside in client applications.
