Configuration
There are multiple environment variables you can configure to modify behaviour of the Waku node:
NWAKU_IMAGE
- the image you want to use for the nwaku container (e.g.NWAKU_IMAGE=statusteam/nim-waku:v0.19.0-rc.0
). You can see the available tags in docker hub.DOMAIN
- domain name pointing to the IP address of your node, when configured the run script will request SSL certs from Let's Encrypt and run Waku node with WebSockets Secure (WSS) options enabled (e.g.DOMAIN=waku.example.com
)NODEKEY
- this env variable allows you to provide a node key as described in operators documentation (e.g.NODEKEY=9f439983aa4851346cfe6e17585e426f482871a43626812e23490895cd602c11
)ETH_CLIENT_ADDRESS
(mandatory) - URL to an HTTP Ethereum node URL on the same network as the contract address. If you're not running your own node, you can get the URL at Infura with the following instructionsRLN_RELAY_CRED_PATH
- path for peristing rln-relay credentialRLN_RELAY_CRED_PASSWORD
- password for encrypting RLN credentialsEXTRA_ARGS
- this variable allows you to specify additional or overriding CLI option for the Waku node which will be appended to thewakunode2
command. (e.g.EXTRA_ARGS="--store=false --max-connections=3000
)CERTS_DIR
- allows you to define a path where SSL certificates are/will be stored. It needs to follow the directory structure produced by Certbot in/etc/letsencrypt
STORATE_SIZE
- overrides the default allowed DB size of waku message storage service. Current default is 1GB. (e.g.STORAGE_SIZE=2GB
orSTORAGE_SIZE=3500MB
)
Log monitoring and troubleshooting
When running the container in detached mode, it's important to note that while notifications about successful container startup are received, any errors occurring during runtime won't be printed to the terminal.
To ensure the proper functioning of the container, it is strongly recommended to monitor the logs. Pay special attention during the first minute of runtime to confirm that the node has spun up successfully.
To check the status of the node, visit http://localhost:8003/health
For real-time logs of the 'nwaku' service, use the following command:
docker-compose logs -f nwaku
In general, to view logs of any service running on Docker Compose, execute:
docker-compose logs -f <service>
To identify different services currently running, refer to the "SERVICE" column displayed when executing:
docker-compose ps
RLN - Rate Limit Nullifier
RLN is the technology used to achieve the rate limiting feature, which combines zero-knowledge proofs, hashing, Merkle tree, Blockchain, etc.
