source code changes

deploy test network using k8s

pre-requirement

• install kubectl
• install kustomize

sample configuration is in k8s/n-nodes.

following nodes are pre-configured:

• boot node named eosio
• 26 bp nodes, named as bpa, bpb, bpc ... bpz
• 9 full nodes, named as node-0, node-1, node-2 ... node-8

in pre-configured network topology:

• full nodes are fully meshed
• each full node connects to 3 bp and eosio
• each bp connects to 3 node

the topology can be easily adjusted in k8s/n-nodes/configmap.yaml

how to deploy to localhost

cd k8s/src/localhost
./apply.sh

how to clean up

cd k8s/src/localhost
./delete.sh

for fast deletion of statefulset, use ./mannual_delete_pod.sh to fast delete all bp and node

how to monitor nodes info

• if deployed locally, use http://localhost to monitor
• if deployed in cloud, you need to config monitor.yaml to enable monitor
• for sample monitor page, view http://dpos-pbft.eosio.sg

shuffle producer scripts is in k8s/scripts

1. use . ./envto setup your env
2. use ./start to deploy contracts and create accounts
3. use ./cron-vote.sh to trigger producer shuffle
