Adding a new node in Quorum¶
Prerequisites¶
To add a new organization in Quorum, an existing quorum network should be running, enode information of all existing nodes present in the network should be available, genesis block should be available in base64 encoding and the geth information of a node should be available and that node account should be unlocked prior adding the new node to the existing quorum network.
Important
Addition of a new organization has been tested on an existing network which is created by Bevel. Networks created using other methods may be suitable but this has not been tested by Bevel team.
Create Configuration File¶
Refer this guide for details on editing the configuration file.
The network.yaml
file should contain the specific network.organization
details along with the enode information, genesis block in base64 encoding and geth account details
Note
Make sure that the genesis block information is given in base64 encoding. Also, if you are adding node to the same cluster as of another node, make sure that you add the ambassador ports of the existing node present in the cluster to the network.yaml
For reference, sample network.yaml
file looks like below for RAFT consensus (but always check the latest network-quorum-newnode.yaml at platforms/quourm/configuration/samples
):

# This is a sample configuration file for Quorum network which has 4 nodes.
# All text values are case-sensitive

# Network level configuration specifies the attributes required for each organization
# to join an existing network.
type: quorum
version: 23.4.0 #this is the version of Quorum
#Environment section for Kubernetes setup
env:
type: "dev" # tag for the environment. Important to run multiple flux on single cluster
proxy: ambassador # value has to be 'ambassador' as 'haproxy' has not been implemented for Quorum
# These ports are enabled per cluster, so if you have multiple clusters you do not need so many ports
# This sample uses a single cluster, so we have to open 4 ports for each Node. These ports are again specified for each organization below
ambassadorPorts: # Any additional Ambassador ports can be given here, this is valid only if proxy='ambassador'
portRange: # For a range of ports
from: 15010
