Requires

• docker
• docker-compose

How to run

git clone https://github.com/waku-org/waku-simulator.git
cd waku-simulator

Configure the simulation parameters. You can place the env variable in an .env file.

export GOWAKU_IMAGE=statusteam/go-waku:v0.7.0
export NWAKU_IMAGE=statusteam/nim-waku:v0.18.0-rc.0
export NUM_NWAKU_NODES=5
export NUM_GOWAKU_NODES=5
export MSG_PER_SECOND=10
export MSG_SIZE_KBYTES=10
docker-compose up -d

This will:

• spin up grafana/prometheus for monitoring, see http://localhost:3000.
• spin up a bootstrap nwaku node.
• spin up a given amount of nwaku/gowaku nodes with specific versions.
• spin up a waku-publisher instance that will inject traffic into the network (see flags for rate and msg size)
