Understand the project

Practical overview

When it fits

Use Kotal when blockchain or IPFS workloads need to be deployed through Kubernetes resources and managed by Kubernetes controllers, and a cluster with cert-manager is available.

Who it is for

  • Infrastructure teams operating blockchain nodes or validators on Kubernetes.
  • Teams managing IPFS peers, cluster peers or swarms in a Kubernetes environment.

Documented uses

  • Deploy RPC, transaction, mining, archive, full or validator nodes for supported protocols.
  • Create private Ethereum networks and Ethereum beacon or validation nodes.
  • Deploy IPFS peers, cluster peers and swarms.
  • Represent protocol-specific infrastructure as Kubernetes custom resources.
Before you choose

Requirements & limits

The project is published under the Apache-2.0 license. Use requires access to a Kubernetes cluster with cert-manager installed; the README recommends KinD for development.

  • The README lists support for Bitcoin, Ethereum, Ethereum 2, NEAR, Polkadot, Chainlink, Filecoin, Stacks, Aptos, Graph and IPFS workloads.
  • The listed protocol custom-resource APIs are marked alpha in the README.
  • Kotal supports at least one client per listed protocol; Ethereum and Ethereum 2 have several named client options.
  • The implementation is written in Go and distributed under Apache-2.0.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Submit the documented Ethereum node resource

Use Kotal’s README example to define and submit an Ethereum node configured with Besu, Goerli and HTTP RPC.

Before you start

  • A Kubernetes cluster with cert-manager and Kotal installed
  • kubectl access to the cluster

Steps

  1. Save the README’s example as ethereum-node.yaml, with apiVersion ethereum.kotal.io/v1alpha1, kind Node, client besu, network goerli and rpc true.

  2. Submit the resource with kubectl apply -f ethereum-node.yaml.

Expected outcome

The example Ethereum node resource is submitted to Kubernetes with the specified client, network and RPC setting.

Guide limitations

  • The README provides a configuration and submission example, not a verified deployment result.
  • The Ethereum custom-resource API is listed as alpha.
