HGF K8S Workshop

Hyperledger Global Forum workshop on deploying Hyperledger Fabric on Kubernetes in development and production.

You may wish to explore https://github.com/aidtechnology/nephos, which helps automate the deployment of similar examples as presented here.

Workshop flow

Cluster creation

In the workshop we demonstrate how to create a managed K8S cluster on Azure:

export GROUP=hgf-workshop
export LOCATION=westeurope

az group create -n $GROUP -l $LOCATION
az aks create -g $GROUP -n ${GROUP}-aks -s Standard_DS2_v2 --kubernetes-version 1.11.5 --node-count 5
az aks get-credentials -g $GROUP -n ${GROUP}-aks

Then you can install Helm, using

kubectl create -f ./helm-rbac.yaml

helm init --service-account tiller

Finally, add the incubator repository, so you are able to install Kafka, etc.

helm repo add incubator https://kubernetes-charts-incubator.storage.googleapis.com/

helm repo update

Development example

We will start with the dev_example, using Cryptogen to set up the identities and cryptographic material.

This is sufficient for Development purposes and will use a very simple setup of 1 peer and 1 (solo) orderer.

Production example

In the second part of the workshop, prod_example, we will be using the Fabric CA to provide the identities and cryptographic material.

This uses as production-ready setup implementing Certificate Authorities persisting identities to PostgreSQL, multiple peers and multiple (Kafka-consensus) orderers.
