2. create new account

copy Public address of the key ใส่ใน docker-compose.yaml ในบรรทัด unlock

# docker run --rm -it -v $PWD:/poa -w /poa ethereum/client-go:v1.10.17 --datadir /poa/node --password password.txt  account new

3. init-genesis

# docker run --rm -it -v $PWD:/poa -w /poa ethereum/client-go:v1.10.17 --datadir /poa/node --nousb  init genesis.json

4. deploy

# docker-compose up -d
# docker-compose logs -f

5. JavaScript Console

https://geth.ethereum.org/docs/rpc/server

# docker exec -it validator sh
# geth --datadir /poa/node attach

	Command
Get Signer	> clique.getSigners()
Check Peers Count	> net.peerCount
Check IP Peers	> admin.peers
Add Peers Static	> admin.addPeer("enode://[email protected]:30303")
Check NodeInfo	> admin.nodeInfo
Add Singer	> clique.propose("0xd881234E73223d1623E0d56789942eA1c0B67890", true)
Remoce Signer	> clique.propose("0xd881234E73223d1623E0d56789942eA1c0B67890", false)
Check Vote	> clique.proposals
Check Vote	> clique.status()

command-line สำหรับ get enode

# docker exec -it validator geth --datadir /poa/node attach --exec 'admin.nodeInfo'

command-line สำหรับ add validator

# docker exec -it validator geth --datadir /poa/node attach --exec 'clique.propose("0x048F519b032bAfa19Cf28D0cbf717a5fd119fA7A", true)'

command-line สำหรับ check validator

# docker exec -it validator geth --datadir /poa/node attach --exec 'clique.getSigners()'

หากต้องการ reset data เพื่อทำการ join ใหม่

7. removedb

# docker run --rm -it -v $PWD:/poa -w /poa ethereum/client-go:v1.10.17 --datadir /poa/node --nousb  removedb

และให้ทำการ init genesis ใหม่อีกครั้งก่อนการ deploy

# docker run --rm -it -v $PWD:/poa -w /poa ethereum/client-go:v1.10.17 --datadir /poa/node --nousb  init genesis.json
