Deploy Beacon Node

The Beacon Chain is the coordination mechanism of the new network, responsible for creating new blocks, making sure those new blocks are valid, and rewarding validators with ETH for keeping the network secure. Source​
Deploy Beacon Node
beacon.yaml
apiVersion: ethereum2.kotal.io/v1alpha1
kind: BeaconNode
metadata:
  name: teku-beacon-node
spec:
  network: pyrmont
  client: teku
  rest: true
  restPort: 8888
  eth1Endpoints:
    - http://goerli-besu-node:8545
In this beacon node, we're using ConsenSys Teku Ethereum 2.0 client client: teku, and syncing the pyrmont network beacon chain network: pyrmont. We also enable REST API server rest: true at port 8888 restPort: 8888. We're connecting to Ethereum 1 endpoint eth1Endpoints: .... Check Ethereum tutorial on how to deploy an Ethereum node.
Let's deploy the beacon node:
kubectl apply -f beacon.yaml
Kotal operator will notice your teku-beacon-node and will create all the necessary pods, persistent volumes, services, configmaps, and secrets.
You can fetch the deployed Ethereum 2.0 BeaconNode using:
kubectl get beaconnodes
It will return an output similar to the following:
NAME               CLIENT   Network   AGE
teku-beacon-node   teku     pyrmont   1m
Fetch Beacon Node Logs
Get the pods created for the beacon node:
kubectl get pods
It will return an output similar to the following:
NAME                 READY   STATUS    RESTARTS   AGE
teku-beacon-node-0   1/1     Running   0          1m
Get the logs of the running beacon node:
kubectl logs -f teku-beacon-node-0
Call /eth/v1/beacon/genesis REST API
Get the service created for the beacon node:
kubectl get services
It will return an output similar to the following:
NAME               TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                      AGE
teku-beacon-node   ClusterIP   10.96.197.218   <none>        9000/UDP,9000/TCP,8888/TCP   7s
Forward the localhost:8888 calls to the beacon node
kubectl port-forward teku-beacon-node-0 8888
In another terminal window, send REST API call to get chain genesis details:
curl localhost:8888/eth/v1/beacon/genesis
You'll get a result similar to the following:
{
  "data": {
    "genesis_time": "1606824023",
    "genesis_validators_root": "0x4b363db94e286120d76eb905340fdd4e54bfe9f06bf33ff6cf5ad27f511bfe95",
    "genesis_fork_version": "0x00000000"
  }
}
Finally delete the beacon node:
kubectl delete beaconnode teku-beacon-node
Kubernetes garbage collector will delete all the resources that has been created by Kotal Ethereum 2.0 BeaconNode controller.
