How to change ports through which hyperledger composer installs runtime

Question

I am installing hyperledger composer and want to change the install options, in particular want to change the port. I found few sites where I found how to set options but did not find the format for it. Can someone tell me how I can change the port?

Answer 1

To change the port you have to modify the existing card. You’ll find it here /home/<user>/.composer/cards/<cardname>/connection.json

This file contains the the details like hosts and ports of the Fabric, then change the port and restart the network.
