Adding a new member organization in Besu¶
Prerequisites¶
To add a new organization in Besu, an existing besu network should be running, enode information of all existing nodes present in the network should be available, genesis file should be available in base64 encoding and the information of besu nodes should be available. The new node account should be unlocked prior adding the new node to the existing besu 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.
Note
The guide is only for the addition of member organization in existing besu network.
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 file in base64 encoding and tessera transaction manager details
Note
Make sure that the genesis flie is provided 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

Run playbook¶
The site.yaml playbook is used to add a new organization to the existing network. This can be done using the following command
ansible-playbook platforms/shared/configuration/add-new-organization.yaml --extra-vars "@path-to-network.yaml"
Verify network deployment¶
