For testing you can use Kubernetes, we have provided a script in launch-tool/launch.py. Please note that launch.py hardcodes a bunch of assumptions about how pods are created, about the fact that we are running under minikube, and that the image itself is named local/node-container.

To use Kubernetes with this project use ./create-docker-image.sh to first create a Docker image. Then:

• ./launch.py boot <num peers> will boot a cluster with num peers participants. Each participant is given a list of all other participants (so you can connect to them).
• ./launch.py list lists all peers in the current cluster. You can use kubectl logs <name> to access the log for a particular pod.
• ./launch.py kill <n> can be used to kill the nth pod.
• ./launch.py launch <n> can be used to relaunch the nth pod (e.g., after it is killed).
• ./launch.py shutdown will kill all pods, shutting down the cluster.
• ./launch.py client-url <n> can be used to get the URL for the nth pod. One example use of this is ./client $(../launch-tool/launch.py client-url 1) to get a client to connect to pod 1.
