Deploying Hyperledger Fabric on a Kubernetes cluster

A collection of kubernetes configurations and helm charts used to deploy a blockchain network.

The current configuration of the network is set to:

• 2 organisations
• 2 peers (1 for each org)
• (optional) 2 couchdb state for the peers
• 1 ca
• 1 orderer (SOLO)

Therefore it is meant to be used mostly for development purposes.

Prerequisites

• Kubernetes
• Helm

DEV: Using a single script

Deployment

cd dev/scripts
./create_all [--with-couchdb]

Cleanup

cd dev/scripts
./delete_all

STAG and PROD: Using Helm charts

Follow the README

Troubleshooting

Error in instantiating your chaincode. Your peer is logging

error trying to connect to local peer: userChaincodeStreamGetter -> ERRO 003 context deadline exceeded

Broken communication between peer and chaincode. The reasons could be different:

• CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE="bridge" is not set on the peer

• CORE_VM_ENDPOINT: “unix:///host/var/run/docker.sock” is not set on the peer

• CORE_PEER_CHAINCODEADDRESS is set with the wrong chaincode addres (It is recommanded to comment this out)

DeliveryBlocks error logged on the peer

[blocksProvider] DeliverBlocks -> ERRO 0b4 [mychannel] Got error &{FORBIDDEN}

Check your orderer logs. There could be some broken communication with your peer.

• The address of the orderer could be wrongly spelled in the configtx.yaml file or different from the one set on the peer

• The admin user who is performing the operations of creating/joining the channel (CLI) is different from the one registered on the peer

Peer crashes immediately after launch

Be sure you to set GODEBUG: “netdns=go” on the peer
