Geth Private-Public Network

Docker-compose based Ethereum Network Validator Nodes set up as a private network (example uses IBFT consensus) with nodes connecting to each other via the public internet.

Running the demo

1. Start the network with docker-compose up in one terminal
2. npm install
3. npm run compile (Optional, the compiled contract is committed)
4. node deploy.js
5. node index.js

Creatign a docker-compose.yml with istanbul-tools

Installing istanbul-tools

Install go: https://golang.org/dl/

Install the actual tool: go get github.com/getamis/istanbul-tools/cmd/istanbul

This will install it under your $GOPATH, so in order to be able to use istanbul you need to make sure $GOPATH/bin is in your $PATH

Now if you type istanbul, you should see:

NAME:
   istanbul - the istanbul-tools command line interface

USAGE:
   istanbul [global options] command [command options] [arguments...]

VERSION:
   v1.0.0

COMMANDS:
     extra    Istanbul extraData manipulation
     setup    Setup your Istanbul network in seconds
     help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --help, -h     show help
   --version, -v  print the version

Generating a config:

istanbul setup --num 4 --docker-compose --save
docker-compose up

Creating an account with ether

1. Install geth
2. geth attach http://localhost:8545
3. Run personnal.newAccount, enter a password
4. log into validator-0 container and retrieve the account
5. modify docker-compose to include that file in validator-0
6. modify docker-compose to give eth to the new account in the genesis block(for each nodes)
7. modify docker-compose to unlock at start up(--unlock '0' --password '/eth/password.txt')
8. if you want the chain data to persist, add a volume for each validator and map it to /eth in each validator(or node)

You can look at docker-compose.yml for the end result.
