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
