Below is an example of a successful output.bitcoin central nzIn my previous article about building a blockchain application, I shared some of the tools, tips and techniques I used to create an end-to-end blockchain web application.bitcoin explorer apiLet’s hone in on a specific part of that and explain in more depth how I built an underlying Ethereum private blockchain for testing purposes.valor bitcoin eurI mentioned that I predominantly used testrpc to stand up a simple, single-node Ethereum instance which had the APIs exposed and some accounts pre-filled with Ether for testing.Testrpc is a great tool, super simple and fast to get started, which makes it ideal for development and if you are new to the tech.However there are some situations where you might want some extra flexibility or you need to test different scenarios where you require a more “production like” setup.

These include - If you find yourself having to set up a private Ethereum cluster (as I did) you’ll find that it’s not actually a straightforward process.While there are one or two pretty clear tutorials out there as well as some scripts both for me had some problems.The scripts prefer that you are running Ubuntu, the preferred/recommended platform for Ethereum and the tutorials contain anywhere between 5-20 steps.I wanted a simple, repeatable and cross platform way to bring up and tear down my clusters.Enter Docker and Docker Compose.Today I’m announcing our open-sourced ethereum-docker which contains a bunch of Dockerfiles and Docker Compose scripts for bringing up standalone full Geth Ethereum nodes or multi-node clusters along with the very nice eth-netstats web dashboard for viewing the status of your cluster.Let’s take it for a spin.To run a single node do: docker-compose -f docker-compose-standalone.yml up -d If you are using Docker-machine with the “default” box you can do: Otherwise on Docker for Mac you can just open http://localhost:8545 this will give you a connection to the JSON RPC API.

To get attached to the geth JavaScript console on the node you can run the following - docker exec -it bootstrap geth --datadir=~/.ethereum/devchain attach From there you should have access to the full JavaScript runtime environment where you can execute commands against the node.To perform tasks like starting and stopping mining you can run: docker exec -it bootstrap geth --datadir=~/.ethereum/devchain --exec 'miner.stop()' attach To bootstrap the cluster run: This will create 3 nodes: 2 Ethereum nodes + 1 netstats node.To access netstats UI you can do: Or on Docker for Mac: And you should see something that looks like: You can scale the number of Ethereum nodes by doing: There you go, you have a private Ethereum cluster you can scale up, down and test your applications with.This provides basic support at the moment for Docker and Docker compose, as always there are a bunch of open tickets on Github for improvements.We would like to add things like support for deploying on top of Kubernetes and Marathon, support for deploying a cluster with IPFS enabled and ability to interact with the cluster nodes and APIs in an easier way.
