Default orderer.yaml in Orderer Docker Image

Q

What is the Default orderer.yaml file in Orderer Docker Image?

✍: FYIcenter.com

A

The default orderer.yaml file in the Orderer Docker Image is the default version of orderer.yaml, which provides settings to control the behavior of the Orderer peer.

If you deploy the Orderer Docker container without your own version of orderer.yaml, the default version in the Orderer Docker image will be used.

Here is how to view the default orderer.yaml file in the Orderer Docker image after it's been deployed to the Orderer Docker container:

1. Attach a "bash" shell to the Orderer Docker container:

$ docker exec -it orderer.example.com bash
root@552c40a524aa:/opt/gopath/src/github.com/hyperledger/fabric# cd

root@552c40a524aa:~# pwd
/root

2. View the default orderer.yaml file:

root@552c40a524aa:~# more /etc/hyperledger/fabric/orderer.yaml

#   Orderer Configuration
General:
    LedgerType: file
    ListenAddress: 127.0.0.1
    ListenPort: 7050
    TLS:
        Enabled: false
    Keepalive:
        ServerMinInterval: 60s
        ServerInterval: 7200s
        ServerTimeout: 20s
    Cluster:

    GenesisMethod: provisional
    GenesisProfile: SampleInsecureSolo
    GenesisFile: genesisblock
    LocalMSPDir: msp
    LocalMSPID: SampleOrg

...

You can also override any settings in the orderer.yaml file by using environment variables included in the docker-compose.orderer.yaml file.

For example, we changed the "GenesisMethod" setting from "provisional" to "file" by the following settings in the docker-compose.orderer.yaml file:

$ cd fabric-orderer

$ more docker-compose-orderer.yaml: 

# Copyright IBM Corp. All Rights Reserved.
version: '2'

volumes:
  orderer.example.com:

networks:
  hello:

services:
  orderer.example.com:
    networks:
      - hello
    container_name: orderer.example.com
    image: hyperledger/fabric-orderer:amd64-1.4.0
    environment:
      - FABRIC_LOGGING_SPEC=INFO
      - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
      - ORDERER_GENERAL_GENESISMETHOD=file
      - ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block

...      

As you can see, Fabrice Orderer is designed with a very flexible configuration mechanism.
