feat(fabric): install multiple chaincodes on peers

Description :

Now BAF is supporting to install single chaincode on peer. I would like to install multiple chaincodes on peers

Proposal Summary:

would like to install multiple chaincodes on peers. And the proposal network.yaml would be like this

network.yaml

1. network:
2.   chaincodes:
3.     - chaincode1: 
4.         ........
5.     - chaincode2:
6.         ........    
7.     - chaincode3:
8.         ........

120.               name: peer1      

                       

Note :

Here with the chaincode section in the network.yaml file defines all the chaincode and its parameters . And in the remaining places where we need to use the chaincode just need to use the name and version of the chaincode.

Hi Suvajith, Manual Deployment Steps: Step 1: Generation of certificates for organization that requires external chaincode Step 2: Create chaincode files with connection.json and metadata.json and package it in .tgz format. Make sure Connection.json should have server address and values of certificates generated. Step 3: Copy the packaged chaincode into organization containers and go into peer cli and install the chaincode using “peer lifecycle chaincode install <chaincode file>” Step 4: Create configmap for certificates generated and map the certificates with external chaincode deployment file, run external chaincode as pod &deployment and expose as a service Step 5: Use the exposed chaincode Service IP to create a DNS name. Step 6: Go inside the peer cli and approve and commit the chaincode If the commit is successful try to invoke the chaincode from cli and query. these manual steps are working fine for now, i am in the middle of automation with bevel…

Hi Suvajit, i have tested the external chaincode deployment with kubernetes and bevel, changes pending with bevel, i am trying to complete it ASAP
