Private ethereum blockchain network with 10 nodes (more can be added) in a docker container. Docker allows you to create, deploy and manage virtualized application containers on a common operating system. follow the instructions below to get the ethereum network working 😃

Docker Toolbox installed.

To download and install Docker Toolbox for your environment please follow the Docker Toolbox instructions.

After Docker Toolbox has been installed, create a default machine to run Docker against.

To run a single test Ethereum node run the following:

$ docker-compose -f docker-compose-standalone.yml up -d

If using docker-machine you should be able to get to the JSON RPC client by doing:

open http://$(docker-machine ip default):8545

You can scale the number of Ethereum nodes by running:

docker-compose scale eth=3

As part of the bootstrapping process we bootstrap 10 Ethereum accounts for use pre-filled with 100 Ether for use in transactions by default.

If you want to change the amount of Ether for those accounts See files/genesis.json.

To get attached to the geth JavaScript console on the node you can run the following

docker exec -it privateethereumdocker_geth_1 geth attach ipc://root/.ethereum/devchain/geth.ipc

Then you can miner.start(), and then check to see if it's mining by inspecting web3.eth.mining. 😄
