Kotal Operator

Kotal operator is a cloud agnostic blockchain deployer that makes it super easy to deploy highly-available, self-managing, self-healing blockchain infrastructure (networks, nodes, storage clusters ...) on any cloud.

What can I do with Kotal Operator ?

Deploy Bitcoin rpc nodes
Deploy ipfs peers and cluster peers
Deploy ipfs swarms
Deploy Ethereum transaction and mining nodes
Deploy Ethereum 2 beacon and validation nodes
Deploy private Ethereum networks
Deploy NEAR rpc, archive, and validator nodes
Deploy Polkadot rpc and validator nodes
Deploy Chainlink nodes
Deploy Filecoin nodes
Deploy Filecoin backed pinning services (FPS)
Deploy Stacks rpc and api nodes
Deploy Aptos full and validator nodes

Kubernetes Custom Resources

Kotal extended kubernetes with custom resources in different API groups.

| Protocol | Description | API Group | Status | | ---------------- | ------------------------------------------------ | --------------------------- | ------ | | Aptos | Deploy Aptos full and validator nodes | aptos.kotal.io/v1alpha1 | alpha | | Bitcoin | Deploy Bitcoin nodes | bitcoin.kotal.io/v1alpha1 | alpha | | Chainlink | Deploy Chainlink nodes | chainlink.kotal.io/v1alpha1 | alpha | | Ethereum | Deploy private and public network Ethereum nodes | ethereum.kotal.io/v1alpha1 | alpha | | Ethereum 2.0 | Deploy validator and beacon chain nodes | ethereum2.kotal.io/v1alpha1 | alpha | | Filecoin | Deploy Filecoin nodes | filecoin.kotal.io/v1alpha1 | alpha | | Graph | Deploy graph nodes | graph.kotal.io/v1alpha1 | alpha | | IPFS | Deploy IPFS peers, cluster peers, and swarms | ipfs.kotal.io/v1alpha1 | alpha | | NEAR | Deploy NEAR rpc, archive and validator nodes | near.kotal.io/v1alpha1 | alpha | | Polkadot | Deploy Polkadot nodes and validator nodes | polkadot.kotal.io/v1alpha1 | alpha | | Stacks | Deploy Stacks rpc and api nodes | stacks.kotal.io/v1alpha1 | alpha |

Client support

For each protocol, kotal supports at least 1 client (reference client):

| Protocol | Client(s) | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Aptos | Aptos Core | | Bitcoin | Bitcoin Core | | Chainlink | Chainlink | | Ethereum | Hyperledger Besu, Go-Ethereum, Nethermind | | Ethereum 2.0 | Teku, Prysm, Lighthouse, Nimbus | | Filecoin | Lotus | | Graph | graph-node | | IPFS | kubo, ipfs-cluster-service | | NEAR | nearcore | | Polkadot | Parity Polkadot | | Stacks | Stacks Node |

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/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

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

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