Examples

Beacon node on the Holesky testnet connected to Holesky via Infura

mode: "beacon"

extraArgs:
  - --network=holesky
  - --ee-endpoint=<EXECUTION-ENDPOINT>

Exposing the P2P service via NodePort

This will make your node accessible via the Internet using a service of type NodePort. When using p2pNodePort.enabled the exposed IP address on your ENR record will be the “External IP” of the node where the pod is running.

Limitations: You can only run a single replica per chart deployment when using p2pNodePort.enabled=true.If you need N nodes, simply deploy the chart N times.

replicas: 1

p2pNodePort:
  enabled: true
  port: 31000

This would create 5 beacon nodes, exposed via Node Port services with the following configuration:

• Node 0: 30000
• Node 1: 30001
• Node 2: 30002
• Node 3: 32000
• Node 4: 30004

Validator node targeting a beacon node service

This example runs a validator on the holesky network that targets a pre-existing teku-beacon service by injecting the all-accounts.keystore.json` file via a secret ENV var. You could use a similar approach to fetch your secrets from some external secret management system (Hashicorp Vault, Azure key vault, etc.):

replicas: 1

mode: validator

initContainers:
  - name: init-keystore
    image: bash:latest
    imagePullPolicy: IfNotPresent
    securityContext:

      export INDEX=$(echo $(hostname)| rev | cut -d'-' -f 1 | rev);
      mkdir -p /data/validator/keys;
      mkdir -p /data/validator/secrets;
      KEY_COUNT="NODE_${INDEX}_KEY_COUNT";
      for ((i = 0 ; i < "${!KEY_COUNT}" ; i++ ));
      do
        key="NODE_${INDEX}_KEY_${i}";
        PUBKEY=$(echo ${!key} | jq '.pubkey' -j);
        echo ${!key} > "/data/validator/keys/0x${PUBKEY}.json";
        secret="NODE_${INDEX}_SECRET_${i}";
        echo ${!secret} > "/data/validator/secrets/0x${PUBKEY}.txt";
        echo "Added 0x${PUBKEY}";
      done
