An Ethereum private network running on Docker to mess with Blockchain and smart contracts.
To provide a simple, private Ethereum setup as close as possible to a production environment where the nodes are completely independent and just share the same network.
The setup is simple enough to allow further experiments (thus the playground name) and deals with all the technical details as Docker deployment, node discovery and stats reporting.
Builds and maintains 3 independent nodes in a Docker network and a bootnode to connect them.
- Vanilla Ethereum: everything is built and setup from scratch
- Each node gets its own IP address and eth account, also:
- broadcasts its default account id from the 9090 TCP port.
- reports stats to the netstat node that is running eth-netstats
- The bootnode node connects nodes dynamically when added into the network
- A netstat node displaying the eth-netstat dashboard
- epl, a CLI tool to perform maintenance operations: build, start, stop, login into nodes, check truffle, etc
- Clone this repo
- cd eth-playground
- ./build.sh
- ./epl deploy
Docker will display 4 nodes (ethbn, eth1, eth2, eth3) running inside the ethnet network.
Once installed the nodes are fully independentent and self-discoverable thanks to the bootnode in place (ethbn).
- epl login nodeName : logs automatically inside the selected node
- epl geth nodeName : opens a geth console inside the selected node
- epl stop : stops the eth network
- epl start: starts the network again
- epl deploy: stops and deploys the whole network again
- epl info: displays the netstat node URL containing the dashboard
