Hyperledger fabric-peer

The Hyperledger fabric is an implementation of blockchain technology, that has been collaboratively developed under the Linux Foundation's Hyperledger Project. It leverages familiar and proven technologies, and offers a modular architecture that allows pluggable implementations of various function including membership services, consensus, and smart contracts (chaincode) execution. It features powerful container technology to host any mainstream language for smart contracts development.

Usage

Vagrant

If Docker running within Vagrant, identify the IP of the Docker daemon host:

$ ip add
...
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    link/ether 02:42:9c:9a:d9:22 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 scope global docker0
       valid_lft forever preferred_lft forever
    inet6 fe80::42:9cff:fe9a:d922/64 scope link
       valid_lft forever preferred_lft forever

in the example output above, that would be 172.17.0.1. We'll use this IP as the value of the CORE_VM_ENDPOINT variable.

To start a single peer instance, without membership services, run the following docker command:

docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true hyperledger/fabric-peer peer node start

Natively on Mac or Windows

If running Docker natively on Mac or Windows, the value of CORE_VM_ENDPOINT should be set to unix:///var/run/docker.sock.

Using Docker Compose

When running in Vagrant, you can use the docker-compose yaml files in the fabric/bddtests directory to start up a network of peers, with or without the membership services.

When running natively on Mac or Windows, the following docker-compose.yml can be used to start a peer without the membership service:

vp0:
  image: hyperledger/fabric-peer
  environment:
    - CORE_PEER_ID=vp0
    - CORE_PEER_ADDRESSAUTODETECT=true
    - CORE_VM_ENDPOINT=http://172.17.0.1:2375
    - CORE_LOGGING_LEVEL=DEBUG
  command: peer node start

The following docker-compose.yml could be used for running Docker for Mac or Windows without the membership services:

vp0:
  image: hyperledger/fabric-peer
  ports:
    - "5000:5000"
    - "30303:30303"
    - "30304:30304"
  environment:
    - CORE_PEER_ADDRESSAUTODETECT=true
    - CORE_VM_ENDPOINT=unix:///var/run/docker.sock
    - CORE_LOGGING_LEVEL=DEBUG
  command: peer node start

Advanced Configuration

Please refer to the Hyperledger Fabric documentation for more advanced configurations, including running with the companion membership services component.
