Run in a custom network

• git clone https://github.com/uhomeio/uhome-harmony
• cd uhome-harmony
• Run Service with custom config:

gradlew runCustom -Dethereumj.conf.file=/path/to/custom.conf

• It is also possible to use CLI to pass parameters:

gradlew runCustom -Dpeer.networkId=10101 -DgenesisFile=/path/to/custom/genesis.json -Dpeer.discovery.enabled=false -Dpeer.active.0.url=enode://0f4a5f92835a4604ecd9639ddcfb86d2a2999ad9328bc088452efffe4a7c6cd0eaaef77c779dc56fc1d0f21cd578eeb92cb5@23.101.151.28:30303

Note: parameters that haven't been substituted by either custom config or CLI will be supplied from ethereumj.conf

Custom config file format

Format of the file should be the same as of ethereumj.conf. It also works to specify only necessary config parameters.

An example:

genesisFile = /path/to/custom/genesis.json
database.dir = database-private

peer {
  networkId = 10101
  listen.port = 50505

  discovery.enabled = false
  active = [
    {url = "enode://6ce05930c72abc632c58e2e4324f7c7ea478cec0ed4fa2528982cf34483094e9cbc9216e7aa349691242576d552a2a56aaeae426c5303ded677ce455ba1acd9d@13.84.180.240:30303"}
    {url = "enode://20c9ad97c081d63397d7b685a412227a40e23c8bdc6688c6f37e97cfbc22d2b4d1db1510d8f61e6a8866ad7f0e17c02b14182d37ea7c3c8b9c2683aeb6b733a1@52.169.14.227:30303"}
  ]
}

sync.fast.enabled = false
