This is a docker compose for a PRIVATE and INSECURE ethereum network - Use it for dev and test purpose only
This ethereum private network uses a genesis block with really low difficulty, this allow you to mine block in ms, useful for test and dev, but this makes the blockchain insecure.
Eth nodes have all rpc api enabled (included admin, db, ecc...), this allow full access from an external ethereum console, but it is insecure!

folder geth-solidity contains a docker for go ethereum with solidity compiler (solc)
folder geth-compose contains a docker compose for a private network with 3 nodes
$ docker-compose build
$ docker-compose up```
The build process may takes some time...
When nodes are up, you can run another docker with an ethereum console
```$ cd geth-solidity
$ ./manage.sh geth-console-node-01```
You can have multiple console connected to different nodes and see how data is replicated between nodes
# Tutorials
Check geth-solidity/console-script for two tutorials: one creates a simple transection between two users, second creates and compiles a smart contract

# Rpc api
Check if a node is connected to another
```curl http://dockerhost:8101 -X POST --data '{"jsonrpc":"2.0","method":"admin_peers","params":[]}'```
