To fix this issue The sample config files in the Hyperledger Fabric main code base are fully commented/documented with all sections (though some are commented out).

Couchdb port mapping in yaml file for Hyperledger Fabric V1.0 network setup


By : brass_eye_cake

this will help The 5984 is the couch db port number, now the mapping of ports from docker-compose-couchdb.yaml file simply defines mapping from docker container into docker host machine. Since there are 4 couchdb container (one for each peer) you cannot map all of them on the same port number, therefore for each one defined different mapping: 5984, 6984, 7984 and 8984 respectively. So it's not mapping to the same port, but from the same port to the different ones. Please refer for docker compose docs here.
Starting from Hyperledger Fabric v1.0 there is no encryption of values in state db, if you would like to proceed and encrypt your data you can do it on application level. For example client could pass AES key via transient map field of the proposal and chaincode will encode params based on that key do the chaincode business logic, decode results back and store them.

Hope this helps A Fabric CA server can be configured with multiple profiles. By default, on the latest version of the CA there are 3 profiles:
code :
signing:
default:
  usage:
    - digital signature
  expiry: 8760h
profiles:
  ca:
     usage:
       - cert sign
       - crl sign
     expiry: 43800h
     caconstraint:
       isca: true
       maxpathlen: 0
  tls:
     usage:
        - signing
        - key encipherment
        - server auth
        - client auth
        - key agreement
