# nwaku-simulator
|
|
|
|
## 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:latest
|
|
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)
|
|
|

# Infrastructure
|
|
|
|
An instance of this service is deployed at https://simulator.waku.org/.
|
|
|
|
It is configured using [`wakusim.env`](./wakusim.env) file, and new changes to this repository are picked up using a [GitHub webhook handler](https://github.com/status-im/infra-role-github-webhook).
|
|
The docker images used are updated using [Watchtower](https://github.com/containrrr/watchtower) as well.
|
|
|
|
For details on how it works please read the [Ansible role readme file](https://github.com/status-im/infra-misc/blob/master/ansible/roles/waku-simulator/). The original deployment issue can be found [here](https://github.com/status-im/infra-nim-waku/issues/79).
