What is docker-hyperledger-fabric-peer?

Docker image with hyperledger fabric peer deployed.

How to use this image?

The docker image is auto built at https://registry.hub.docker.com/u/yeasy/hyperledger-fabric-peer/.

In Dockerfile

FROM yeasy/hyperledger-fabric-peer:latest

Local Run with single node

The peer command is the main command, you can use it as the start part.

E.g., see the supported sub commands with the help command.

$ peer help
02:10:10.359 [crypto] main -> INFO 001 Log level recognized 'info', set to INFO


Usage:
  peer [command]

Available Commands:
  node        node specific commands.
  network     network specific commands.
  chaincode   chaincode specific commands.
  help        Help about any command

Flags:
      --logging-level="": Default logging level and overrides, see core.yaml for full syntax


Use "peer [command] --help" for more information about a command.

Hyperledger relies on a core.yaml file, you can mount your local one by

$ docker run -v your_local_core.yaml:/go/src/github.com/hyperledger/fabric/peer/core.yaml -d yeasy/hyperledger-fabric-peer peer node start help

The storage will be under /var/hyperledger/, which should be mounted from host for persistent requirement.

Your can also mapping the port outside using the -p options.

  • 7050: REST service listening port (Recommened to open at non-validating node)
  • 7051: Peer service listening port
  • 7052: CLI process use it for callbacks from chain code
  • 7053: Event service on validating node

Local Run with chaincode testing

Start your docker daemon with

$ sudo docker daemon --api-cors-header="*" -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

Pull necessary images, notice the default config require a local built openblockchain/baseimage. We can just use the yeasy/hyperledger image instead.

$ docker pull yeasy/hyperledger:latest
$ docker tag yeasy/hyperledger:latest hyperledger/fabric-baseimage:latest
$ docker pull yeasy/hyperledger-fabric-peer:latest

Check the docker0 bridge ip, normally it should be 172.17.0.1. This ip will be used as the CORE_VM_ENDPOINT=http://172.17.0.1:2375.

$  ip addr show dev docker0
4: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    link/ether 02:42:f2:90:57:cf 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:f2ff:fe90:57cf/64 scope link
    valid_lft forever preferred_lft forever

PBFT consensus

PBFT requires at least 4 nodes.

$ git clone https://github.com/yeasy/docker-compose-files
$ cd docker-compose-files/hyperledger
$ docker-compose up

More details, please refer to hyperledger-compose-files.

After the cluster starts up, enter into the container

$ docker exec -it vp0 bash

Inside the container, deploy a chaincode using

$ peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'
