ethereum

Ethereum is a decentralized platform for building applications using blockchain.

TL;DR;

$ helm install stable/ethereum

Introduction

This chart deploys a private Ethereum network onto a Kubernetes cluster using the Helm package manager. This network is not connected to MainNet, and for further information on running a private network, refer to Geth's documentation. This chart is comprised of 4 components:

  1. bootnode: used for Geth node discovery
  2. ethstats: Ethereum Network Stats
  3. geth-miner: Geth miner nodes
  4. geth-tx: Geth transaction nodes with mining disabled whose responsbility is to respond to API (websocket, rpc) queries

Prerequisites

  • Kubernetes 1.8

Installing the Chart

  1. Create an Ethereum address and private key. To create a new Ethereum wallet, refer to this blog post which will walkthrough the following instructions in greater detail:

    $ git clone https://github.com/vkobel/ethereum-generate-wallet
    $ cd ethereum-generate-wallet
    $ pip3 install -r requirements.txt
    $ python3 ethereum-wallet-generator.py
    
    Private key: 38000e15ca07309cc2d0b30faaaadb293c45ea222a117e9e9c6a2a9872bb3bcf
    Public key:  60758d37d431d34b920847212febbd583008ec2a34d00f907d48bd48b88dc2661806eb99cb6178312d228b2fd08cdb88bafc352d0395ae09b2fe453f0c4403ad
    Address:     0xab70383d9207c6cc43ab85eeef9db4d33a8ad4e8
  2. Install the chart as follows:

    $ helm install --name my-release stable/ethereum
        --set geth.account.address=[PUBLIC_ADDRESS]
        --set geth.account.privateKey=[PRIVATE_KEY]
        --set geth.account.secret=[SECRET]

    using the above generated example, the configurations would equate to:

    • geth.account.address = 0xab70383d9207c6cc43ab85eeef9db4d33a8ad4e8
    • geth.account.privateKey = 38000e15ca07309cc2d0b30faaaadb293c45ea222a117e9e9c6a2a9872bb3bcf
    • geth.account.secret = any passphrase that Geth will use to encrypt your private key

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

The following table lists the configurable parameters of the vault chart and their default values.

Parameter Description Default
imagePullPolicy Container pull policy IfNotPresent
nodeSelector Node labels for pod assignmen
bootnode.image.repository bootnode container image to use ethereum/client-go
bootnode.image.tag bootnode container image tag to deploy alltools-v1.7.3
ethstats.image.repository ethstats container image to use ethereumex/eth-stats-dashboard
ethstats.image.tag ethstats container image tag to deploy latest
ethstats.webSocketSecret ethstats secret for posting data my-secret-for-connecting-to-ethstats
ethstats.service.type k8s service type for ethstats LoadBalancer
geth.image.repository geth container image to use ethereum/client-go
geth.image.tag geth container image tag to deploy v1.7.3
geth.tx.replicaCount geth transaction nodes replica count 2
geth.tx.service.type k8s service type for geth transaction nodes ClusterIP
geth.tx.args.rpcapi APIs offered over the HTTP-RPC interface eth,net,web3
geth.miner.replicaCount geth miner nodes replica count 3
geth.miner.account.secret geth account secret my-secret-account-password
geth.genesis.networkId Ethereum network id 98052
geth.genesis.difficulty Ethereum network difficulty 0x0400
geth.genesis.gasLimit Ethereum network gas limit 0x8000000
geth.account.address Geth Account to be initially funded and deposited with mined Ether
geth.account.privateKey Geth Private Key
geth.account.secret Geth Account Secret

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example, to configure the networkid:

$ helm install stable/ethereum --name ethereum --set geth.genesis.networkid=98052

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install stable/ethereum -f values.yaml
