Install Kotal

Kotal requires access to Kubernetes cluster with cert-manager installed.

For development purposes, we recommend KinD (Kubernetes in Docker) to create kubernetes clusters and tear down kubernetes clusters in seconds:

kind create cluster

After the cluster is up and running, install cert-manager:

kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.2.0/cert-manager.yaml

Install kotal custom resources and controllers:

kubectl apply -f https://github.com/kotalco/kotal/releases/download/v0.1-alpha.5/kotal.yaml

Example

Ethereum node using Hyperleger Besu client, joining rinkeby network, and enabling RPC HTTP server:

# ethereum-node.yaml
apiVersion: ethereum.kotal.io/v1alpha1
kind: Node
metadata:
  name: ethereum-node
spec:
  client: besu
  network: rinkeby
  rpc: true

kubectl apply -f ethereum-node.yaml
