hyperledger composer existing network install

composer version v0.19.10 Fabric version 1.1 21 nodes: 3 CLI 3 CA 3 orders 3 www 3 api 6 peers channel name: common

My fabric network is up and running and I can commit a transaction. But I am trying to add composer playground into the mix. If I try a default install it fails because it wants to use composerchannel. My question is. Is there an way to install composer to an existing fabric deployment.

The Composer Playground uses Business Connection Cards that it finds on your local file system. By default these are under a folder under your home folder e.g. ~/.composer (Maybe you have created a standard PeerAdmin card for a standard 1 peer Development Fabric? )

If you have already connected to the Fabric with Composer, you will have some cards that you already use to commit a transaction. If you have separate machines you can use composer card export on the original machine and composer card import on the machine running Playground.

If you have not connected to the Fabric yet using Composer you might like to look at the Composer Tutorial for MultiOrg which goes through creating cards to connect Composer to the Fabric - it is not your exact scenario, but should provide enough information for you to move forward.

To answer the channel question, one of the files in the "Card" is a connection.json file and in that file the channel to use is specified. (By default composer uses a channel called composerchannel)
