Member Peers of a Channel

Q

How to find out which Peers are members of the "mychannel" channel?

✍: FYIcenter.com

A

One way to find out which Peers are members of the "mychannel" channel is to visit each peers and check their joined channel list:

1. Connect to the CLI container:

$ docker exec -it cli bash
bash-4.4#

2. Check joined channel list on each peer with the help peer switching scripts:

bash-4.4# source peer0-org1.sh
bash-4.4# peer channel list
Channels peers has joined:
mychannel

bash-4.4# source peer1-org1.sh
bash-4.4# peer channel list
Channels peers has joined:
mychannel

bash-4.4# source peer0-org2.sh
bash-4.4# peer channel list
Channels peers has joined:
mychannel

bash-4.4# source peer1-org2.sh
bash-4.4# peer channel list
Channels peers has joined:
mychannel

As you can see, there is only 1 channel, "mychannel", on the network. And all 4 peers have joined the same channel.
