What components are included in my Hyperledger Composer Environment?

The fabric-dev-servers.tar.gz package provides the 4 components running as Docker containers to form your Hyperledger Composer Environment.

You can identify Hyperledger Composer by their container names from the output of the "docker ps" command:

$ docker ps
CONTAINER ID    IMAGE                               ... NAMES
------------    -----                                   -----
...             hyperledger/fabric-peer:1.2.1       ... peer0.org1.example.com
...             hyperledger/fabric-couchdb:0.4.10   ... couchdb
...             hyperledger/fabric-orderer:1.2.1    ... orderer.example.com
...             hyperledger/fabric-ca:1.2.1         ... ca.org1.example.com

peer0.org1.example.com - A peer node owned by org1.example.com. It listens inbound transaction requests at port 7051. It also emits outbound event messages at port 7053.
