Example of private ethereum cluster running on Cloud Foundry
The up.sh script will stand up 3 apps:
bootnodes- one instance of the service discovery node for the networkminers- one instance of a geth miner node for block creationnodes- one instance of a geth node to execute transactions
You can access any of these nodes with cf ssh and use the geth binary at app/geth and the data dir at app/data. The genesis file and accounts used are provided with the repo and should not be reused in any production environment.
The miner comes up in a stopped state to prevent run-away CPU usage.
The test.sh script will:
- Stop the miner if running
- Mine 1 block to create ETH for account 0
- Initiate a transfer of ETH from account 0 to account 1
- Mine 1 block to complete the transfer
- Show the balances of each account to confirm the transfer has occured
- Cloud Foundry CLI
- Docker
- Account on Cloud Foundry environment with Container-to-Container networking and SSH enabled
- Recommended: Pivotal Web Services
- Supported on Pivotal Cloud Foundry 1.10 and higher
