Installing Kotal
To get started, you need access to a Kubernetes cluster with cert-manager installed. Here’s how to install Kotal:
bash
# Create a Kubernetes cluster using KinD for development purposes
kind create cluster
# Once the cluster is up and running, install cert-manager
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml
# Install Kotal custom resources and controllers
kubectl apply -f https://github.com/kotalco/kotal/releases/download/v0.3.0/kotal.yaml
Example of Deploying an Ethereum Node
If you’d like to deploy an Ethereum node using the Hyperledger Besu client and join the Goerli network with RPC HTTP server enabled, here’s how you do it:
yaml
# ethereum-node.yaml
apiVersion: ethereum.kotal.iov1alpha1
kind: Node
metadata:
name: ethereum-node
spec:
client: besu
network: goerli
rpc: true
bash
# Deploy the node
kubectl apply -f ethereum-node.yaml
Troubleshooting Ideas
If you encounter issues while deploying with Kotal, here are some troubleshooting steps:
- Ensure your Kubernetes cluster has sufficient resources allocated.
- Check the status of the cert-manager installation to ensure it’s running properly.
- Verify the Kotal custom resources were installed correctly using
kubectl get crds. - Look at the logs of your Kubernetes pods for any error messages with
kubectl logs.
