What is purpose of "CORE_PEER_CHAINCODELISTENADDRESS" environment variable?

Question

In core.yaml for peer we can define env. variable as chaincodelistenaddress (CORE_PEER_CHAINCODELISTENADDRESS).

• what is purpose of this environment variable ?
• Can we use this variable for instead of DEV mode ?
• Currently I am trying to deploy network on Openshift platform. In this case when I set variable as CORE_PEER_CHAINCODELISTENADDRESS : peer01.local.com:7051 as same as CORE_PEER_ADDRESS :peer01.local.com:7051

it gives me error as address already bind while starting peer container.

• If i assign different port CORE_PEER_CHAINCODELISTENADDRESS : peer01.local.com:7052

it gives me error as can not assign address peer01.local.com:7052.

This refers to the endpoint that the peer would listen to with regarding for the chaincode service.

Yes, you can use the variable when using dev-mode.

With regarding the errors - please specify your fabric version as things have changed slightly in the master branch.

In v1.0.0 (release branch), you can make your chaincode bind to the same port as the peer.

Also - please upload your core.yaml and the peer log for further information. Alternatively you can seek advice in the fabric channel in https://chat.hyperledger.org/channel/fabric
