The Open Block Mesh Project

DRAFT

The Open Block Mesh Project

The objective of this project is to run Hyperledger 0.6 under the control of Kubernetes to provide Production-Grade Container Orchestration for Hyperledger containers.

This work was commissioned by ANZ Bank which is a member of the Hyperledger Project under the direction of

Ben Smillie ([email protected])
Technical Manager - Emerging Technology
ANZ Bank

The goal of this project is to provide a rapid platform to stand up a Hyperledger peer fabric for development purposes under the control of Kubernetes.

The stand-up of the entire platform should take about six minutes and the tear down about one minute.

A majority of the time taken to stand up the fabric is GKE assigning external IP addresses.

Assumptions

This project assumes Kubernetes to be at version 1.4 or later.

This project assumes the hosting environment is Google Container Engine and Google Compute Engine.

All of the work detailed should be performed on a system with the correct version of gcloud and kubectl and has access to GKE and GCE.

As the Hyperledger project currently only supports build from source, this project utilizes two images built from source.

See: hyperledger/fabric#2336

These images are currently stored on Docker Hub under :

jackyhuang/fabric-peer
jackyhuang/fabric-baseimage

The metadata label: version: 0.6 is used to version these images.

These images are used in this project to build the fabric and run the chain code.

Technical End State Objectives

The fabric will be installed into a hyperledger-06 namespace to provide soft multi-tenancy and isolation.

Four Validating Peers Pods are built so that a single failure can be tolerated in the Fabric.

These Validating Peers are shown as Kubernetes Pods in the diagram above.

They are identified as: vp0 (root node), vp1, vp2 and vp3

This fabric uses the pbft (Practical Byzantine Fault Tolerance) protocol.

Four Validating Peer Kubernetes Services are installed.

These services are identified by a svc prefix.

They are:

svc-hl-vp0 - vp0 Hyperledger Kubernetes service
svc-hl-vp1 - vp1 Hyperledger Kubernetes service
svc-hl-vp2 - vp2 Hyperledger Kubernetes service
svc-hl-vp3 - vp3 Hyperledger Kubernetes service
svc-hl-vp-lb - vp loadbalanced Hyperledger Kubernetes service

The Validating Peer loadbalanced service svc-hl-vp-lb provides a way to interact with the fabric via a service instead of directly interacting with any of the peers in the fabric.

The Kubernetes Services provide stable service addresses for the Validating Peer Kubernetes Deployments running behind them.

The following labels have been used in this project :

version: "0.6" to support upgrades
environment: development to support different environments
provider: gke to denote the platform provider
city: "melbourne" to support geographic distributed installations

This project uses kind: Deployment Replica Sets to support upgrades moving forward.

The metadata label: version: 0.6 is to support future upgrades.

Kubernetes Cluster Setup

This guide is build using

GKE Google Container Engine
GCE Google Compute Engine

Kubernetes Project Quotas

Request the following additional quotas:

Up to 30 In-use IP addresses

Container Fabric Setup

Sign in to Google Cloud Platform

Create a Project

hyperledger

Setup a GKE (Google Container Engine) cluster with four nodes

Under the Compute tab..Container Engine

Create a Container Cluster.
Give your cluster a meaningful name such as : hyperledger-cluster
Type in a Description: Development Hyperledger cluster
Select a zone geographically close to your location to ensure low network latency.
The default machine type of 1vCPU and 3.75 GB RAM is sufficient for initial development.
Consider larger systems if you encounter resource constraints.
Select 4 under Size, this equates to 4 VM instances.
One VM Instance (node) for each Validating Peer.

If you have the gcloud already setup you can use the CLI to provision the container cluster with :

gcloud container clusters create gce-asia-east1 --scopes cloud-platform --zone asia-east1-b --num-nodes 4

Click on the cluster.

Select Connect to the cluster to get access details. Copy the value it should be similar to this:

gcloud container clusters get-credentials hyperledger-cluster --zone asia-east1-a --project hyperledger-xxxxxx

Install gcloud on the linux system you wish to access your cluster from.

sudo apt-get -y install python
wget https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-131.0.0-linux-x86_64.tar.gz
tar -zxvf google-cloud-sdk-131.0.0-linux-x86_64.tar.gz
cd google-cloud-sdk
./install.sh

Logout and login for profile changes to take effect.

Setup gcloud :

gcloud auth login
Enter the verification code
gcloud components install kubectl
gcloud container clusters get-credentials hyperledger-cluster --zone asia-east1-a --project hyperledger-xxxxxx
gcloud beta auth application-default login

Once kubectl is installed use this command to get a list of your nodes kubectl get nodes

root@ubuntu-512mb-sgp1-01:~# kubectl get nodes
NAME                                                 STATUS    AGE
gke-hyperledger-cluster-default-pool-214902e7-kezx   Ready     2d
gke-hyperledger-cluster-default-pool-214902e7-l6y5   Ready     2d
gke-hyperledger-cluster-default-pool-214902e7-vi6e   Ready     2d
gke-hyperledger-cluster-default-pool-214902e7-vtyp   Ready     2d

Label each node to ensure each validating peer runs on a separate node and can tolerate a hardware failure in the fabric.

One Label on each separate node :

node=node-vp0
node=node-vp1
node=node-vp2
node=node-vp3

Using each node from the kubectl get nodes command above label the nodes on your cluster.

Sample output from kubectl label nodes command.

kubectl label nodes gke-hyperledger-cluster-default-pool-214902e7-kezx node=node-vp0
kubectl label nodes gke-hyperledger-cluster-default-pool-214902e7-l6y5 node=node-vp1
kubectl label nodes gke-hyperledger-cluster-default-pool-214902e7-vi6e node=node-vp2
kubectl label nodes gke-hyperledger-cluster-default-pool-214902e7-vtyp node=node-vp3

Note the following values you will need them later for the svc-hosts.sh script :

project name
zone

CORE_VM_ENDPOINT Setup

Setup a single GCE (Google Compute Engine) instance to run the chain code

This is the CORE_VM_ENDPOINT instance

Under the Compute tab..Compute Engine

Create Instance
Instance Name: core-vm-endpoint
Select the same zone as selected above for the hyperledger-cluster cluster.
The default machine type of 1vCPU and 3.75 GB RAM is sufficient for initial development.
Boot Disk: Ubuntu 16.04 LTS
Boot Disk Type: Standard Persistent disk
Size: 20 GB

Install Docker on the GCE instance :

Connect to the GCE instance via

gcloud compute --project "hyperledger-xxxxxx" ssh --zone "asia-east1-a" "core-vm-endpoint"

Deploy Chain Code Example

During peer chaincode deploy the chain code is submitted to the ledger in a form of transaction and distributed to all nodes in the network. Each node creates a new Docker container with this chaincode embedded. After that container will be started and Init method will be executed.

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

It may take up to a minute for the chain code containers to start on `core-vm-endpoint'

You can check that the chaincode containers are running by docker ps -a on the core-vm-endpoint

watch docker ps -a

Initial chaincode images will come up

Query Chain Code Example

During “Query” - chain code will read the current state and send it back to user. This transaction is not saved in blockchain.

peer chaincode query -n ee5b24a1f17c356dd5f6e37307922e39ddba12e5d2e203ed93401d7d05eb0dd194fb9070549c5dc31eb63f4e654dbd5a1d86cbb30c48e3ab1812590cd0f78539  -c '{"Function": "query", "Args": ["a"]}'

Sample Output

21:01:54.733 [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Successfully queried transaction: chaincodeSpec:<type:GOLANG chaincodeID:<name:"ee5b24a1f17c356dd5f6e37307922e39ddba12e5d2e203ed93401d7d05eb0dd194fb9070549c5dc31eb63f4e654dbd5a1d86cbb30c48e3ab1812590cd0f78539" > ctorMsg:<args:"query" args:"a" > >

Troubleshooting

If you experience any issues please check the hosts file on the core-vm-endpoint.

If there was a delay in assigning external IP addresses sometimes there will be "PENDING" entries in the hosts file as opposed to the correct IP entries.

Execute kubectl get svc -n hyperledger-06 to a list of the correct IP addresses to place in the /etc/hosts file
