• Deploy Ethereum 2 beacon and validation nodes
• Deploy private Ethereum networks
• Deploy Filecoin nodes
• Deploy Filecoin backed pinning services (FPS)

Kotal extended kubernetes with custom resources in different API groups.

Group	Description	API Group	Status
Ethereum	Deploy ethereum nodes	ethereum.kotal.io/v1alpha1	alpha
IPFS	Deploy IPFS peers, cluster peers, and swarms	ipfs.kotal.io/v1alpha1	alpha
Filecoin	Deploy Filecoin nodes	filecoin.kotal.io/v1alpha1	alpha
Ethereum 2.0	Deploy validator and beacon chain nodes	ethereum2.kotal.io/v1alpha1	alpha
Algorand	Deploy relay and participation nodes	algorand.kotal.io/v1alpha1	coming soon 🚀

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.4/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
