# waku-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 NWAKU_IMAGE=quay.io/wakuorg/nwaku-pr:2759-rln-v2
|
|
export NUM_NWAKU_NODES=5
|
|
export TRAFFIC_DELAY_SECONDS=15
|
|
export MSG_SIZE_KBYTES=10
|
|
export PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
|
|
export ETH_FROM=0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266
|
|
export RLN_RELAY_EPOCH_SEC=10
|
|
export RLN_RELAY_MSG_LIMIT=2
|
|
|
|
docker-compose --compatibility up -d
|
|
```
|
|
|
|
|
|
This will:
|
|
* create a private blockchain and attach a block explorer.
|
|
* deploy RLN contract to it.
|
|
* spin up a bootstrap nwaku node.
|
|
* spin up a given amount of nwaku nodes with specific versions.
|
|
* register an RLN membership for each nwaku node.
|
|
* spin up a `rest-traffic` instance that will inject traffic into the network via the REST API.
|
|
* see block-explorer `http://localhost:3000`.
|
|
* see grafana with node metrics `http://localhost:3001`.
|
|

## notes
|
|
|
|
The default login/password for grafana is `admin`/`admin`.

|
|
|
|
```
|

sysctl net.ipv4.neigh.default.gc_thresh3=32000
|
|
```
|

|
|
Compose V2 users should spin up the containers with the following command:
|
|
|
|
```
|
|
docker-compose --compatibility up -d

# 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).
|
|
|
|
The deployed branch is [deploy-wakusim](https://github.com/waku-org/waku-simulator/tree/deploy-wakusim).
