Deploy Validator Client

Staking is the act of depositing 32 ETH to activate validator software. As a validator you’ll be responsible for storing data, processing transactions, and adding new blocks to the blockchain. This will keep Ethereum secure for everyone and earn you new ETH in the process. This process, known as proof-of-stake, is being introduced by the Beacon Chain. source​

Deploy Validator Client

validator.yaml
apiVersion: ethereum2.kotal.io/v1alpha1
kind: Validator
metadata:
name: teku-validator
spec:
client: teku
network: pyrmont
beaconEndpoints:
- http://teku-beacon-node:9999
graffiti: Validated by Kotal
keystores:
- secretName: my-validator
In this validator client, we're using ConsenSys Teku Ethereum 2.0 client client: teku, validating pyrmont network blockchain network: pyrmont, connecting to beacon node endpoint using beaconEndpoints: ..., setting the graffiti text to include in the propsed blocks graffiti: validated by Kotal, and loading a validator keystore using keystores: ... from a kubernetes secret called my-validator.
The keystores loaded using spec.keystores[].secretName from kubernetes secret, must contain two data keys:
  • keystore key hodling the BLS12-381 keystore JSON file
  • password key holding the encryption key of the keystore.
Let's deploy the validator client:
kubectl apply -f validator.yaml
Kotal operator will notice your teku-validator and will create all the necessary pods, persistent volumes, services, configmaps, and secrets.
You can fetch the deployed Ethereum 2.0 Validator using:
kubectl get validators
It will return an output similar to the following:
NAME CLIENT NETWORK AGE
teku-validator teku pyrmont 1m

Fetch Validator Logs

Get the pods created for the validator client:
kubectl get pods
It will return an output similar to the following:
NAME READY STATUS RESTARTS AGE
teku-validator-0 1/1 Running 0 1m
Get the logs of the running validator pod:
kubectl logs -f teku-validator-0
You'll get an output similar to the following:
...
21:21:30.668 INFO - Storing validator data in: /opt/teku/kotal-data/validator
21:21:30.751 INFO - Loading 1 validator keys...
21:21:31.759 INFO - Loaded 1 Validators: 83dbb18
...
Finally delete the validator client:
kubectl delete validator teku-validator
Kubernetes garbage collector will delete all the resources that has been created by Kotal Ethereum 2.0 Validator controller.
