Cello follows a typical Master-Workers architecture.
Master: Holds Cello services to manage the blockchain networks inside Workers via corresponding management APIs. Typically, Master Node provides web dashboard (port
8080) and RESTful APIs (port
80). It is recommended to use Linux (e.g., Ubuntu 18.04) as the Master.
Worker: Nodes to hold blockchain networks. Cello supports several types of
worker nodefrom single server to cluster. Take
Swarmfor example, the Worker's management APIs (i.e., Docker daemon APIs) should be accessible (typically on port
2375) from the Master Node.
Currently we support Docker Host or Swarm Cluster as Worker Node. More types will be added soon.
Docker Host: Setup Docker Host as a Worker Node.
Docker Swarm: Create a Docker Swarm.
vSphere: Setup vSphere as a Worker Node.
Kubernetes: Setup Kubernetes as a Worker Node.
Ansible: Setup Ansible as a Worker Node.
Special Configuration for Production
Here we describe the setups for development usage. If you want to deploy Cello for production, please also refer to the Production Configuration.
